Shopify Offsite Payment App Extension

I have created a Offsite Payment App Extension. I have provided the payment session URL to the extension that redirects the customers from shopify checkout to the payment portal to complete the payments.

Now I have no idea how to redirect the customer back to the payment portal to the shopify checkout with the payment details. In the payment session request we get the payment cancel URL not the checkout URL.

Kindly guide me how to complete this process.

I have followed this documentation:
https://shopify.dev/docs/apps/build/payments/request-reference#offsite-payment

Thanks

hii @Anilket26 . have you had any success? also, is there hope that we could communicate privately for possible paid help?

Hi can you share a file structure and the redacted file for shopify.extension.toml file I am working on same but not able to redirect from the checkout page to my extension checkout page.
