Hello, here is a message from our developer. We are trying to integrate EE4 with a payment gateway.
hi. so i found the reason why it doesn’t’ work but the problem is that i need to pass some custom value to paystack to get it back then on transaction verification page but seems i am not able to do that. the webhook url event espresso uses to verify payments is dynamic, it is changed each transaction but paystack doesn’t allow me to pass each time new webhook url to it so i am not able to verify the payment securely.
Can anyone help with this?
I’m sorry, but I’m not really sure what you are asking:
EE already dynamically sets the ‘webhook’ url, you can’t change this but you can add additional params to the query string.
Judging by your post I’m assuming you are trying to integrate with PayStack?
If so, hows do PayStack support passing additional variables to the IPN/Webhook/return_url?
Do they not POST the user back with the variables in the request?
