For help to migrate to the '''PayPal''' module from '''PayPal Basic''', see the [[PayPal_Checkout_Migration_Guide|PayPal Checkout Migration Guide]].
  
−
For One Time payments, all PayPal supported payment methods are made available. For Subscription purchases, payment methods such as PayPal Credit are not available due to restrictions imposed by PayPal.
+
=== Limitations and Restrictions ===
  
−
==Express Checkout==
+
<div class="docs-alert-warning">
 +
This module requires an HTTPS-secured connection. If the WHMCS installation's domain does not have a valid SSL certificate or the '''[[General_Tab|WHMCS System URL]]''' value does not begin with <tt>https://</tt>, the connection between WHMCS and PayPal will not work.

</div>
 +
 +
The following limitations and restrictions apply to PayPal Checkout:
 +
 +
* Users who choose to use one of the PayPal Checkout express checkout options within the view cart step of the shopping cart workflow will not be asked to select a payment gateway in the checkout step.
 +
* The option to apply credit during checkout for existing customers who have a credit balance is not displayed during express checkout to avoid conflicts with the pre-authorized amount at PayPal.
 +
* MarketConnect Upsells will not be displayed after payment has been pre-authorized with PayPal to avoid changes being made to the cart total after authorization of the payment amount with PayPal.
 +
* '''Convert to for Processing''' is not offered in the module configuration. Payments will be made in the client's selected currency.
 +
* The system will offer clients the subscription option if they are ordering a recurring product on a monthly or annual billing cycle. The modules configuration does not offer an option to force only one-time payments.
  
−
Clicking any of the checkout with PayPal buttons will launch a modal based payment authorization process.
+
=== Unlinking Your PayPal Account ===
  
−
Users will be asked to login to their PayPal account and confirm they approve payment, before being returned to the WHMCS shopping cart to complete the checkout process.
+
<div class="docs-alert-warning">

+
Clicking any '''Checkout with PayPal''' will launch a modal-based payment authorization process. Users will log in to their PayPal accounts and confirm their payment before returning to WHMCS to complete the checkout process.
−
 
+
−
[[File:Paypal-checkout-invoice-subscription-notice.png]]
+
* When first-time customers return to WHMCS, the registration form will pre-fill the name, email, and billing address.
−
 
+
* Existing users who have not already authenticated will see the login screen with their email address pre-filled.
−
Users can click on the More Details link to view the details of the subscription associated with an invoice, including Subscription ID, Last Payment Amount and Date, Next Payment Date and Start Date.
+
−

+
−
 
+
[[File:Paypal-checkout-cart-buttons.png]]
−
Users can still elect to make a payment using the "Make a Payment" link. Selecting this option will reveal the PayPal payment buttons allowing the customer to make a one-off payment for the invoice balance. Note that the module will not allow users to create a subscription whilever an Active Subscription is found to be present.
 
−
 
 
−
==Admin Area Subscription Management==
 
−
 
 
−
Admin users can view the Subscription ID associated with a Product/Service or a Domain via the service details view within the WHMCS admin area.
 
−
 
 
−
For modules that support it such as PayPal Checkout, up to 2 additional buttons will be available alongside the Subscription ID field:
 
−
 
 
−
* '''Get Subscription Info''' - This button can be used to view subscription details in much the same way as clients have access to from an invoice within the client area. Clicking this button will open a modal and query the PayPal API to fetch the real-time status and information relating to the given PayPal Subscription ID.
 
−
* '''Cancel Subscription''' - This button can be used to cancel a subscription.
 
−
The subscription management buttons are shown in the screenshot below taken from the Product/Service view within the WHMCS admin area.

==Getting Started==
+
=== Express Checkout ===
  
−
To get started with the PayPal Checkout module, you will need a PayPal Business account. If you don't already have one, please click here.
+
Express checkout users will not see a payment method choice after authorizing payment by PayPal. Instead, they will see a message indicating that they have pre-approved payment.
  
−
Once you have an account, follow the steps below to activate and configure PayPal Checkout for use in WHMCS.
+
Carts that only have '''One-Time''', '''Biennial''', or '''Triennial''' Payment items will immediately include Express Checkout buttons. For carts that contain at least one recurring item (on a '''Monthly''' or '''Annual''' billing cycle), the client can proceed through the standard WHMCS checkout routine and select PayPal as the payment method. Upon placing an order, they will be redirected to PayPal to create a subscription.
 +
 +
== Disputes ==
 +
 +
In WHMCS 8.3 and higher, you can manage disputes for this module from within WHMCS at '''Billing > [[Disputes]]'''.
  
−
* Begin by logging in to the WHMCS admin area and navigating to Setup > Payment Gateways
+
== Troubleshooting ==
−
* Select the "All Payment Gateways" tab
+
−
* Find the "PayPal Checkout" option and click the button to activate it
+
=== Missing and Orphaned Subscriptions ===
−
* Visit https://developer.paypal.com/ in a new browser window
+
−
* Select the "Log into Dashboard" link
+
On WHMCS 8.7.2 or higher, the system may log one of the following entries to the '''Activity Log''' at '''Configuration (<i class="fa fa-wrench" aria-hidden="true"></i>) > [[System Logs]]''':
−
* Enter your PayPal account credentials
+
−
* Upon successful login, you should be automatically redirected to the "My Apps & Credentials" page
+
==== The system has detected a missing subscription. The subscription is not associated with any services, but the event was attributable to a client and/or invoice. ====
−
* Select the Live mode button
+
−
* Click Create App
+
This message indicates that the subscription is not associated with any service, addon, or domain in the WHMCS database for your installation. However, the system did find an alternate ID to use to identify an associated invoice or client.
−
* Enter a name for your app when prompted. We recommend using your company name.
+
−
* Click the Create App button
+
If this message begins with <tt>[PAYMENT.SALE.COMPLETED]</tt>, there is not an immediate issue, but you should review the subscription in order to understand why the ID is missing.
−
* Copy the automatically generated Client ID and Secret and enter those into the PayPal Checkout module configuration fields within WHMCS where prompted
+
−
* Click Save Changes to complete the setup process
+
* If the subscription is active, update the ID to associate the subscription with the relevant service. If you do not, the message will repeat for each payment.
−
 
+
* If the subscription has been cancelled, the cancellation event was received before the final payment. You do not need to take further action.
−

−
* The option to apply credit during checkout for existing customers who have a credit balance is not displayed during express checkout to avoid conflicts with the pre-authorized amount at PayPal.
+
* If this message begins with <tt>[PAYMENT.SALE.COMPLETED]</tt> and you updated to WHMCS 8.7.2 '''more''' than 48 hours ago, there is a '''serious problem'''. The PayPal account received payment, but WHMCS has not recorded it. Investigate the issue immediately to determine the necessary action.
−
* MarketConnect Upsells will not be displayed after payment has been pre-authorized with PayPal to avoid changes being made to the cart total after authorization of the payment amount with PayPal.
+
* If this message begins with <tt>[BILLING.SUBSCRIPTION.CREATED]</tt> and you updated to WHMCS 8.7.2 within the last 48 hours, this is a normal indicator that a user checked out using PayPal just before you upgraded. You do not need to take further action.
−
* Subscription payments cannot be pre-authorized, and therefore are final at the time of payment approval. This occurs prior to checkout being completed which leads to two possible consequences:
+
−
* Subscription payments occur prior to fraud checks having been performed for the order
+
=== Missing Payments in WHMCS ===
−
** Due to the inability to pre-authorize a subscription and capture later, if a user fails to complete the checkout process after authorizing a PayPal Subscription, the subscription payment may still occur.
+
 +
If a client pays an invoice and a completed payment is deposited into your PayPal account, but not recorded in WHMCS, you can troubleshoot this by navigating to '''Billing > [[Gateway Log]]'''.
 +
 
 +
The explanations and resolutions for common problems are listed below:
 +
 
 +
==== Signature Verification Failed ====
 +
 
 +
''Signature Verification Failed'' indicates a problem in the payment notification anti-spoof verification. When a payment notification is received from PayPal, WHMCS makes an API request to PayPal confirming that the notification originated from PayPal.
 +
 
 +
Seeing this typically indicates that a subscription renewal payment was made through a different [https://developer.paypal.com/docs/integration/admin/manage-apps/# integration app] from the one currently linked to your WHMCS installation.
 +
 
 +
This situation can arise if '''Unlink PayPal Account''' on the module configuration was used after the PayPal subscription was originally created. Once the unlink function is used, the subscription payments that pre-date it can no longer be recorded in WHMCS. Such subscriptions will need to be cancelled via the PayPal website. Clients can then create a new subscription under the current integration app linked to your WHMCS installation when their next invoice is due.
 +
 
 +
==== An unknown error occurred. Please try again ====
 +
 
 +
''unknown error occurred'' will be displayed if data saved by the PayPal payment button is invalid, such as the amount, client's name, email address, postal address, postal code, or country code.
 +
 
 +
To capture more details, use the [[Troubleshooting_Module_Problems|Module Debug Log]]. Examine the logged request and response data. It should become apparent what data is missing or incomplete from the client's profile. For example:
 +
 
 +
'''Request:'''
 +
<div class="source-cli">
 +
{"intent":"CAPTURE","purchase_units":[{"description":"Bronze Hosting - Invoice #123",<br/>
 +
"amount":{"currency_code":"USD","value":"25.00"},"invoice_id":123}],"payer":{"name":<br/>
 +
{"given_name":"WHMCS","surname":"Support"},"email_address":"email@example.com",<br/>
 +
"address":{"address_line_1":"123 Test Street","postal_code":"ABC 123","country_code":""}}}
 +
</div>
 +
 
 +
'''Response:'''
 +
<div class="source-cli">
 +
{"name":"INVALID_REQUEST","message":"Request is not well-formed, syntactically incorrect,<br/>
 +
or violates schema.","debug_id":"abc123","details":[{"field":"/payer/address/country_code",<br/>
 +
"value":"","location":"body","issue":"INVALID_STRING_LENGTH","description":"<br/>
 +
The value of a field is either too short or too long."},
 +
</div>
 +
 
 +
In this case, the '''Country Code''' at the end of the request is empty. To correct this, go to '''Profile''' for the client and ensure that a country is selected. Then, click '''Save Changes'''.
 +
 
 +
If a '''Billing Contact''' is specified, make the change via '''Contacts''' instead.
 +
 +
If the '''currency_code''' value is not amongst [https://developer.paypal.com/docs/api/reference/currency-codes/#paypal-account-payments PayPal API's supported currency list] then the PayPal Basic module can be used as an alternative in conjunction with the [[Payment_Gateways#Setting_Up_Gateway_Modules|Convert to For Processing setting]] to transparently convert the payment amounts into a currency which is supported by PayPal.

Adding the PayPal Payment Gateway

To set up the PayPal payment gateway in WHMCS:

  1. Ensure that your WHMCS installation uses an HTTPS-secured connection with a valid SSL certificate. If it does not, this module will not function correctly.
  2. Go to the appropriate location for your version of WHMCS:
    • For WHMCS 8.0 and later, go to Configuration () > Apps & Integrations or Addons > Apps & Integrations.
    • For WHMCS 7.10 and earlier, go to Setup > Products/Services > Payment Gateways and choose All Payment Gateways.
  3. Click Activate & Configure for PayPal.
  4. When the system prompts you, log in to your existing PayPal account or sign up for a new one.
  5. When the system prompts you, confirm permission for the WHMCS application to access your account.
  6. Click Confirm to continue. API credentials will populate and WHMCS will save them automatically. The page will refresh.
  7. Check Show on Order Form to display this payment method in the Client Area during checkout.
  8. Click Save Changes.

Migrating from PayPal Basic

For help to migrate to the PayPal module from PayPal Basic, see the PayPal Checkout Migration Guide.

Limitations and Restrictions

This module requires an HTTPS-secured connection. If the WHMCS installation's domain does not have a valid SSL certificate or the WHMCS System URL value does not begin with https://, the connection between WHMCS and PayPal will not work.

For more information, see PayPal Checkout SSL Requirement.

The following limitations and restrictions apply to PayPal Checkout:

  • Users who choose to use one of the PayPal Checkout express checkout options within the view cart step of the shopping cart workflow will not be asked to select a payment gateway in the checkout step.
  • The option to apply credit during checkout for existing customers who have a credit balance is not displayed during express checkout to avoid conflicts with the pre-authorized amount at PayPal.
  • MarketConnect Upsells will not be displayed after payment has been pre-authorized with PayPal to avoid changes being made to the cart total after authorization of the payment amount with PayPal.
  • Convert to for Processing is not offered in the module configuration. Payments will be made in the client's selected currency.
  • The system will offer clients the subscription option if they are ordering a recurring product on a monthly or annual billing cycle. The modules configuration does not offer an option to force only one-time payments.

Unlinking Your PayPal Account

Do not use this option if there are PayPal subscriptions you wish to keep.

Clicking Unlink PayPal Account will irreversibly remove the link to your PayPal account. Subscription payments will no longer be recorded in WHMCS.

Updating the PayPal Webhook URL

If your WHMCS installation's URL has changed because you moved it, you must update the webhook URL in PayPal. This will allow WHMCS to continue to record transactions.

To update the PayPal webhook URL:

  1. Log in to https://developer.paypal.com/developer/applications.
  2. Select Live, which will then display the WHMCS app.
  3. Click on the app name.
  4. Scroll down to the Live Webhooks section and click the edit (pencil) icon.
  5. Update the Webhook URL to the correct address, ending with /modules/gateways/callback/paypalwebhooks.php.
  6. Click Save.

Checkout

With PayPal Checkout, users can elect to check out using PayPal.

Clicking any Checkout with PayPal will launch a modal-based payment authorization process. Users will log in to their PayPal accounts and confirm their payment before returning to WHMCS to complete the checkout process.

  • When first-time customers return to WHMCS, the registration form will pre-fill the name, email, and billing address.
  • Existing users who have not already authenticated will see the login screen with their email address pre-filled.

The View Cart step of the order process will display the PayPal Checkout options in addition to the default Checkout:

Paypal-checkout-cart-buttons.png

Express Checkout

Express checkout users will not see a payment method choice after authorizing payment by PayPal. Instead, they will see a message indicating that they have pre-approved payment.

Carts that only have One-Time, Biennial, or Triennial Payment items will immediately include Express Checkout buttons. For carts that contain at least one recurring item (on a Monthly or Annual billing cycle), the client can proceed through the standard WHMCS checkout routine and select PayPal as the payment method. Upon placing an order, they will be redirected to PayPal to create a subscription.

Disputes

In WHMCS 8.3 and higher, you can manage disputes for this module from within WHMCS at Billing > Disputes.

Troubleshooting

Missing and Orphaned Subscriptions

On WHMCS 8.7.2 or higher, the system may log one of the following entries to the Activity Log at Configuration () > System Logs:

The system has detected a missing subscription. The subscription is not associated with any services, but the event was attributable to a client and/or invoice.

This message indicates that the subscription is not associated with any service, addon, or domain in the WHMCS database for your installation. However, the system did find an alternate ID to use to identify an associated invoice or client.

If this message begins with [PAYMENT.SALE.COMPLETED], there is not an immediate issue, but you should review the subscription in order to understand why the ID is missing.

  • If the subscription is active, update the ID to associate the subscription with the relevant service. If you do not, the message will repeat for each payment.
  • If the subscription has been cancelled, the cancellation event was received before the final payment. You do not need to take further action.

This message indicates that the subscription is not associated with any service, addon, or domain in the WHMCS database for your installation. Additionally, the system could not find an alternate ID to use to identify an associated invoice or client.

  • If this message begins with [PAYMENT.SALE.COMPLETED] and you updated to WHMCS 8.7.2 more than 48 hours ago, there is a serious problem. The PayPal account received payment, but WHMCS has not recorded it. Investigate the issue immediately to determine the necessary action.
  • If this message begins with [BILLING.SUBSCRIPTION.CREATED] and you updated to WHMCS 8.7.2 within the last 48 hours, this is a normal indicator that a user checked out using PayPal just before you upgraded. You do not need to take further action.

Missing Payments in WHMCS

If a client pays an invoice and a completed payment is deposited into your PayPal account, but not recorded in WHMCS, you can troubleshoot this by navigating to Billing > Gateway Log.

The explanations and resolutions for common problems are listed below:

Signature Verification Failed

Signature Verification Failed indicates a problem in the payment notification anti-spoof verification. When a payment notification is received from PayPal, WHMCS makes an API request to PayPal confirming that the notification originated from PayPal.

Seeing this typically indicates that a subscription renewal payment was made through a different integration app from the one currently linked to your WHMCS installation.

This situation can arise if Unlink PayPal Account on the module configuration was used after the PayPal subscription was originally created. Once the unlink function is used, the subscription payments that pre-date it can no longer be recorded in WHMCS. Such subscriptions will need to be cancelled via the PayPal website. Clients can then create a new subscription under the current integration app linked to your WHMCS installation when their next invoice is due.

An unknown error occurred. Please try again

unknown error occurred will be displayed if data saved by the PayPal payment button is invalid, such as the amount, client's name, email address, postal address, postal code, or country code.

To capture more details, use the Module Debug Log. Examine the logged request and response data. It should become apparent what data is missing or incomplete from the client's profile. For example:

Request:

{"intent":"CAPTURE","purchase_units":[{"description":"Bronze Hosting - Invoice #123",
"amount":{"currency_code":"USD","value":"25.00"},"invoice_id":123}],"payer":{"name":
{"given_name":"WHMCS","surname":"Support"},"email_address":"email@example.com",
"address":{"address_line_1":"123 Test Street","postal_code":"ABC 123","country_code":""}}}

Response:

{"name":"INVALID_REQUEST","message":"Request is not well-formed, syntactically incorrect,
or violates schema.","debug_id":"abc123","details":[{"field":"/payer/address/country_code",
"value":"","location":"body","issue":"INVALID_STRING_LENGTH","description":"
The value of a field is either too short or too long."},

In this case, the Country Code at the end of the request is empty. To correct this, go to Profile for the client and ensure that a country is selected. Then, click Save Changes.

If a Billing Contact is specified, make the change via Contacts instead.

If the currency_code value is not amongst PayPal API's supported currency list then the PayPal Basic module can be used as an alternative in conjunction with the Convert to For Processing setting to transparently convert the payment amounts into a currency which is supported by PayPal.
