PUT product does not update the title

Retired Boards Appdev Merchandising

Topic summary

A user encountered a 301 redirect error when attempting to update a product title via Shopify’s REST API using PUT requests in Postman. Despite receiving what appeared to be a successful response, the product title remained unchanged in the store.

Root Cause:
The issue stemmed from using the store’s public/custom domain (e.g., ‘example.myshopify.com’) instead of the correct admin domain format visible in the Shopify admin panel (e.g., ‘999xxx.myshopify.com’).

Key Findings:

  • GET requests worked with the public domain due to automatic redirection
  • PUT, POST, and DELETE requests failed with 301 redirects when using the public domain
  • The 301 response indicated a redirect was occurring rather than the expected 200 success response

Resolution:
Always use the store’s admin domain format (‘999xxx.myshopify.com’) for all API requests. This ensures all HTTP verbs (GET, PUT, POST, DELETE) function correctly without redirect issues.

The discussion is resolved with the user successfully identifying and fixing their configuration error.

I’m trying to start using the REST API, so am working in Postman first. I can get products, but I am unable to update a product’s title. The PUT appears to work (I get back a 301) but the title never changes in the store. I am sure I am doing something really stupid.

Here’s what I am trying (this is Postman’s code output, replaced sensitive info with ‘{}’) :

curl --location --request PUT ‘https://{}.myshopify.com/admin/api/2023-10/products/8852085932353.json’
–header ‘Content-Type: application/json’
–header ‘X-Shopify-Access-Token: {}’
–header ‘Cookie: request_method=PUT’
–data ‘{
“product”: {
“id”: 8852085932353,
“title”: “New product title”
}
}’

Here’s the raw log of the request/response:

The 301 results in the unchanged product coming back, and the Shopify admin confirms the title has not been updated.

Any ideas?

Hi Ciiboivy,

If you’re seeing a 301 being returned, this suggests that something related to a redirect is taking place - ideally you should be seeing a 200 response. I would doublecheck that the URL you’re using in the PUT request is correct (that the store URL is accurate and the endpoint is in the right format.

One thing to check would be to run the request in Terminal to see if there’s a config issue in Postman that might be causing this.

So…newbie error. I was using the external friendly domain name of my store instead of my store name that you can see when logging into the admin (e.g. 'https://admin.shopify.com/store/999xxx) - the ‘999xxx’ part is what you should be using as ‘999xxx.myshopify.com’ - this works for GETs but not for anything else. It was 301 redirecting me back to the correct URL with a GET.

Glad you figured this out - I was think it was URL/ domain related. Best of luck with the rest of your project!

I should have said that the my public store URL works when issuing a GET, but fails on a PUT/POST/DELETE - you will get 301 redirected back to a ‘999xxx.myshopify.com’ URL. To fix the problem, always use ‘999xxx.myshopify.com’ as the domain, and all 4 verbs will work.
