Hey @cusursuz,

Can you please clarify what you mean by you can't run handleCreatePaymentRedirect method, are you receiving an error? If so, please share.

Thanks!

[cusursuz]

we receive response back with POST request.
I will ask if bank can give response with GET request

[cusursuz]

The bank can only respond using the POST method.
Is there another solution?

[jonwaldstein]

@cusursuz that should still be possible, however it looked liked the gateway was still stripping the return_url query params which would mean its not reaching the correct url. do you have documentation for this gateway you are working with?

[cusursuz]

Yes, this is
https://github.com/maibank/maibapi

[jonwaldstein]

@cusursuz from the docs it says:

The second step is the redirected user to the Maib Payment Gateway URL using the TRANSACTION_ID.
When the transaction has been finalised, the Maib Payment Gateway redirects the user to your callback URL where you get the transaction status

I'm not sure how to supply the callback URL - but that should be the url from $this->generateSecureGatewayRouteUrl()

[cusursuz]

Return url begin with return_url=http://customgateway.local?give-listener=give-gateway&.....
Is it possible to change to ...http://customgateway.local/SOME-PATH?give-listener=give-gateway&.....
Thanks

[jonwaldstein]

Out of curiosity, why do you want to change the path?

Technically yes, you could probably change that with php but our generated routes are meant to be used in conjunction with the method specified in $secureRouteMethods to work properly with our gateway api.

[cusursuz]

I understood you
P.S. It’s more difficult to change the callback at a bank

[jonwaldstein]

I saw this in the docs:

Need to write an email to maib commerce support: ecom@maib.md with the request including The Merchant IP and callback URL, to receive access and certificate for testing.

Do you know if the callback url can be dynamic using an api or does it have to be a specific url including domain name? That could be a challenge in a WordPress environment where our plugin is distributed. Typically payment gateways will need a specific webhook url to reply asynchronously - but the return url / callback url is usually something given programatically.

[cusursuz]

can't be dynamic
We make request to change it for main domain ex.: our_site.md/
