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 i set dynamic webhook url each time i am generating new transaction?
this is an example of webhook url http://demo1.spylabs.net/transactions/?e_reg_url_link=1-b413f08eb1bae1cbd4f23dded417e9cc&ee_payment_method=new_payment_method_offsite
where e_reg_url_link=1-b413f08eb1bae1cbd4f23dded417e9cc is a transaction id which is new each time

Hi there,
I’m sorry, but I’m not really sure what you are asking:
can i set dynamic webhook url each time i am generating new transaction?
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?
