Title: Compatibility with GoCardless plugin (HTTP ERROR 403) Last modified: November 25, 2022 --- # Compatibility with GoCardless plugin (HTTP ERROR 403) * Resolved [Ludovic S. Clain](https://wordpress.org/support/users/ludovicsclain/) * (@ludovicsclain) * [3 years, 6 months ago](https://wordpress.org/support/topic/compatibility-with-gocardless-plugin-http-error-403/) * Hi there 👋  I have just spoken with the support of the GoCardless plugin and it appears that BBQ Firewall is overzealous and causes 403 errors after purchase when redirecting to the site. Indeed, when I deactivate BBQ Firewall the GoCardless plugin works correctly. Here is a screenshot of the Webhook: [https://markuphero.com/share/gvFLIAgZYgnLHB6G9IP7](https://markuphero.com/share/gvFLIAgZYgnLHB6G9IP7) Thank you for your help!

Can you let me know the steps to repeat it on default WordPress install? * Thread Starter [Ludovic S.

Also, I read about the BBQ Whitelist addon, I think I need to Whitelist something, but I don’t know what… * Plugin Author [Jeff Starr](https://wordpress.org/support/users/specialk/) * (@specialk) * [3 years, 6 months ago](https://wordpress.org/support/topic/compatibility-with-gocardless-plugin-http-error-403/#post-16233950) * Yeah that’s really the ticket to resolving the issue: getting the URL that is blocked, and then use the whitelist plugin to ignore the offending pattern. We’re not allowed to log in to client sites, but if you can determine the URL, I can help you get set up with the whitelist plugin. * Thread Starter [Ludovic S.

[https://markuphero.com/share/gvFLIAgZYgnLHB6G9IP7](https://markuphero.com/share/gvFLIAgZYgnLHB6G9IP7) * Maybe this URL [https://staging.waomizik.re/wc-api/WC_Gateway_GoCardless/?request=webhook](https://staging.waomizik.re/wc-api/WC_Gateway_GoCardless/?request=webhook) but I am not sure * The HTTP ERROR 403 screenshot: [https://markuphero.com/share/A2NcbkxY5dhna18NNyls/3](https://markuphero.com/share/A2NcbkxY5dhna18NNyls/3) - This reply was modified 3 years, 6 months ago by [Ludovic S.
