Based on the credential validation logic in Dify, errors like 403 or "invalid_param" (400) during xAI model configuration almost always mean the credentials provided (such as the API key) are missing, malformed, or not matching the expected schema for that provider. Even if your API key looks correct, double-check that:

  • The key is entered in the exact field required by the xAI provider schema (sometimes the variable name or field label must match exactly).
  • All other required fields in the credential form are filled in, not just the API key.
  • There are no leading/trailing spaces or invisible characters in your API key.
  • The configuration method matches what xAI expects (predefined-model vs customizable-model). Some providers require per-model credentials, others just a unified provider credential. See the provider configuration guide.

If you’re still seeing the error, it’s possible the xAI plugin’s credential schema or validation logic is stricter than expected, or the API key is being rejected by the xAI backend. Reviewing the provider credential schema and ensuring all required variables are present and valid is key. The validation process is strict and will raise errors if any required credential is missing or not formatted as expected (see code).

If you can share the exact error message or a screenshot of the credential form, I can help pinpoint the issue further.

To reply, just mention @dosu.

I directly copied the API Key from xAi and then pasted it here. I am very sure it is correct @dosu

@dosubot[bot] commented on GitHub (Jun 5, 2025):

If you're certain the API key is correct, here are a few things to try based on how Dify validates credentials:

  • Make sure there are no invisible characters or extra spaces in the API key field—sometimes copying from a web UI can add these.
  • Double-check that every required field in the credential form is filled, not just the API key. The schema is strict: missing or blank fields will cause errors, even if the key itself is valid.
  • Try adding the model one by one instead of configuring everything at once—this workaround has helped with similar 403 errors for other providers.
  • If xAI expects a specific endpoint or format, ensure the API base URL and model selection match exactly what xAI's docs specify.
  • If possible, test the API key with a direct curl request or Postman to confirm it works outside Dify.

Dify treats all providers generically, so any schema mismatch or missing field will trigger these errors, not just an invalid key. If you have access to the provider schema (YAML or plugin config), check that the variable names and requirements match what you're entering. If you still get the error, it could be a compatibility issue between Dify and the xAI API or plugin, not just the key itself.
