I was developed my custom offsite payment gateway for my GiveWP. I need to update the donation status in my WP site according the result from my Payment Gateway status, how can I do this ? I have a little bit problem with notify_url, can I use notify_url to update my donation status ?

Thanks for your help

I am currently using WordPress version 6.4.2 and WooCommerce version 8.3.1 in previous version my custom payment gateway plugin is working but when I updated the WP and WooCommerce it is no longer visible in the checkout page. It say’s, “There are no payment methods available. This may be an error on our side. Please contact us if you need any help placing your order.” in the Payment Options tab.

I have installed and activated the plugin and enabled it also. There is no error and no warning even when I have set WP to debug mode. I have tried this in multiple server’s still I am facing the same issue.

Thank you in advance.

Thanks in advance. Regards,

I am trying to add a custom payment Gateway [Braintree] to the marketplace.
I go from Settings> Payment Setting and although the plugin of Braintree is installed and appears as payment method on Woocommerce it doesn’t sync with Marketplace.

I ve found a tip here: https://wclovers.com/knowledgebase/wcfm-marketplace-custom-payment-gateway-developers-guide/

but I don’t know in which php file to put it and how exactly in order to achieve it.

Any ideas? Thanks a lot

and this one:
plugins
->woocommerce
–>gateways
—>cheque

Neither one works. Any help?
