I've currently developed a Shopify app in which I'm tryiing to integrate the Billing API.
I referred the docs.
In order to create the first test transaction, I called the POST request https://myshop.myshopify.com/admin/recurring_application_charges.json
It returned a successfull response that contained recurring_application_charge
JSON object. In this object, there was a field called confirmation_url
. On hitting that URL, I received an error. It's mentioned below.
I just want to know that is this the right procedure that I'm following to test the payments? What exactly needs to be done in this situation?
