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.

ifount a solution to my endpoint publicly availeble but still can’t create new crrier service from my server with post request provided by shopify api

@csam my error is 400 badrequest

this is my code :

and this is my console :

when i made get request from frontend to my (“/add”) get request to create new carrier service with REST api provided by shopify api it return error 400 bad request
