Hi,
Thanks for the message.
I tried to replace the code and I get 301 error now
Topic summary
Issue: 401 Unauthorized when calling Shopify REST Admin API (Products) from a PHP script for a custom app using basic auth (API key/password embedded in the URL).
Key points:
- 401 indicates failed authentication; likely due to incorrect credentials, missing permissions, or malformed URL.
- Advice given: verify API key/password, ensure app has required product read/write scopes, confirm API version (2023-10) and endpoint (/admin/api/2023-10/products.json), and check rate limits and Shopify status. Use cURL with HTTPS and Basic Auth for clearer errors.
- Technical note: 301 Moved Permanently was later observed, typically a redirect caused by incorrect endpoint, HTTP→HTTPS enforcement, or malformed URL.
Actions/Outcome:
- Switched to cURL and saw a 301; an image was shared showing the redirect (not essential to resolution).
- Root cause identified as an error in the URL; correcting it resolved the API access.
Status: Resolved. No remaining open questions or disagreements.
