Two Separate PayPal Accounts?

That is currently only possible with this PHP snippet:

If you need guidance implementing custom PHP functions on your website, we have this guide here: https://givewp.com/documentation/resources/adding-custom-functions-to-your-wordpress-website/

In addition to that, you’ll want to login to both PayPal accounts and ensure that their IPN is configured to point to your website with the Give IPN Listener. See this FAQ doc on where you can find that and what it should look like:

Thanks!
