Update carrier services return 404 error

Retired Boards Appdev Fulfillment Api

Topic summary

Main issue: POST/PUT requests to the carrier_services endpoint return errors, while GET requests succeed.

  • Initial state: PUT/POST returned 404. The app reportedly has both Read and Write shipping permissions. The user discovered their endpoint was behind a store password and asked how to make it public.
  • Clarification: A responder noted a password block would not typically produce a 404 and requested the full POST/PUT URL for diagnosis.

Latest update: After making the endpoint publicly accessible, attempts to create a carrier service from the server now return 400 Bad Request.

  • The user triggers creation via a frontend call to a backend “/add” route. Code samples and console output are provided as images, which are central to understanding the request payload/headers.

Status and next steps:

  • No confirmed solution yet; the issue shifted from 404 to 400 after removing password protection.
  • Pending details include the exact URL being used and verification of the request body and headers shown in the screenshots. The discussion remains open.

Hi @jon2022

Does your app have both Read and Write access for shipping?

@csam yes

i found that my endpoint protected by store password

how to make it public endpoint ?

Could you please provide the full URL of the endpoint you’re trying to POST/PUT to? If it was blocked by a password, it wouldn’t be returning a 404 response.
