API: 403 'Forbidden' response after a call to a Shopify 'canary' server

Richard33 · ‎08-22-2023

We have an in-house app that uses the Shopify API.
We use it to fulfil orders.

Lately, when we try to fulfil an order, we get an error response:
403 Forbidden

For every order, we get this response 4-5 times, and then it works!

Successful fulfilment

During a successful fulfilment, there are these calls:

A successful fulfilment also contains the header response:

X-Shopify-Stage: production

Unsuccessful fulfilment

An unsuccessful fulfilment only has the first call:

This call is successful, but during the next one, get the above '403 Forbidden' error message

However the header response is different:

X-Shopify-Stage: canary

Observations

We can infer that the problem may be when Shopify returns a response from

X-Shopify-Stage: canary

instead of

X-Shopify-Stage: production

then the subsequent call fails.

We can also infer that the problem occurs in the call to

GET /admin/api/2023-04/orders/xxxxxxxxxxxxx/fulfillment_orders.json
