There’s no page at this address | After enabling the Recurring charge API in Nodejs app
i have created a Shopify public app using node with shopify CLI , and for payment i enabled the recurring charge API after that the major issue occurred.
So after running the code locally with the ngrok tunneling when i click on the provided Url i was successfully able to redirect to the initial oAuth page and after oAuth it will redirect to the Billing Approval page and after approval i was able to redirect to the App Dashboard.
All these Works fine when i run it locally, and the issue begins when i deployed My app in Heroku and and try to re-install it in my store.
These Screenshots are the correct work flow of my application when i run it locally with ngrok tunneling.
So after deployed in heroku i uninstalled my app in the development store to check the working in the production and after whitelisting the Url
i go to the App -> Myapp -> test in development store -> Install app.
Here the issue comes.
After clicking the Install App it doesn't redirect to the initial oAuth it shows like Invalid Url
it was working fine initially but the issue happens after implemented the code for recurring Billing in the server.js file
The code portion will be mentioned below

If anyone can covey there thoughts on this and share there suggestions on this it will be awesome and very helpful.
Thanks
Hi Henry
When i uncomment the code that you mentioned, it shows the following error.
initially the app will direct to the billing page and when we click on the Approve then it is not getting redirected to my app dashboard page.
It shows that site can't reach or Undefined.
The url appeared - https://undefined/admin/oauth/authorize?client_id=7db4f02ae21a1d663629a17110658006&scope=write_products%2Cwrite_script_tags&redirect_uri=https%3A%2F%2F12c5-103-160-233-158.ngrok.io%2Fauth%2Fcallback&state=986183926163707&grant_options%5B%5D=per-user
The issue will be after calling the billing function it will redirect to the confirmation url and when we click on the approve page and it come back in the server then the shop will be undefined there.
Hi Henry,
We may be running into a similar issue... Here's the call sequence for initiating recurring charge:
Request:
{"recurring_application_charge": {"name": "Standard", "price": 0, "return_url": "https://zumigostore4.myshopify.com/admin/apps/deriskify", "test": "true", "capped_amount": 500, "terms": "Name Address Phone verification\n USA Phones: USD 0.20;\n Canada Phones: USD 0.30;"}}
Response:
{"recurring_application_charge": {"id": 24549851288, "name": "Standard", "api_client_id": 6068747, "price": "0.00", "status": "pending", "return_url": "https://zumigostore4.myshopify.com/admin/apps/deriskify", "billing_on": null, "created_at": "2022-02-08T13:57:49-08:00", "updated_at": "2022-02-08T13:57:49-08:00", "test": true, "activated_on": null, "cancelled_on": null, "trial_days": 0, "capped_amount": "500.00", "trial_ends_on": null, "balance_used": 0.0, "balance_remaining": 500.0, "risk_level": 0.0, "decorated_return_url": "https://zumigostore4.myshopify.com/admin/apps/deriskify?charge_id=24549851288", "confirmation_url": "https://zumigostore4.myshopify.com/admin/charges/6068747/24549851288/RecurringApplicationCharge/conf..."}}
When the browser visits the confirmation_url, it gets a 404:
This was working fine until a few days back. Any ideas why this is failing now?
Thanks
