Fixing 403 errors when scraping
Distinguish missing authorization, content blocks, and configuration failures.
Understand the response
A 403 response means the server refused the request. Record the status, endpoint and a redacted response sample. Confirm that your account and application are permitted to access the resource.
Diagnose before retrying
Check credentials, permissions and the endpoint against its documentation. Compare with a request to a fixture you control. Do not repeatedly retry the same refused request.
When access is restricted, use an approved API or ask the site operator for access. Changing a provider does not grant permission.
Keep failures in the denominator
Count authorization and content-check failures separately in your error breakdown. A successful HTTP response containing a block page still fails a content-success check.
