Help regarding hosted payment sim about hosted-payment-sim HOT 5 CLOSED

Hi @satyendrakumarsingh you should pass all of the parameters received in the POST request from shopify that have a prefix of "x_" apart from the "x_signature". All the params should be merged into a string that's sorted alphabetically with the format "keyvaluekeyvalue...". This string should then be signed using HMAC-SHA256 with the HMAC key set to the password you enter for your gateway in your shops payment settings, as can be seen under "Gateway Signing Mechanism" here. The result of this signing can then be compared against the x_signature parameter passed from Shopify.

When responding you'll need to redirect the customer to x_url_complete with all the values shown here as query parameters appended to the complete url. Meanwhile creating an async POST request to x_url_callback with the request body set to the same query params you passed in the x_url_complete redirect.

I know this is only repeating what's in the docs but sometimes a second explanation can help, and hopefully this helps you.

Thanks Dan! Just to add to this Satyendra, you can check out the docs over at https://docs.shopify.com/api/sdks/hosted-payment-sdk/develop-gateway to see a detailed example of this signing mechanism. The relevant example is about halfway down the page.

Hi @prasanthrubyist when shopify store redirect to hosted payment gateway shopify store sends post(http method) request parameters you have to receive that post request and process all the needed request parameters and after that its up to you that how you can use that request parameters with your payment processor. After that you have to return post(http method) response parameters to the given x_url_complete , x_url_callback. So that shopify store update the order status based on the payment status.
