OAuth Request Failure with Wix Integration in n8n Workflow

Below is some guidance to help troubleshoot OAuth errors like the one you’re seeing. Although the Wix API isn’t explicitly documented in our common issues guides, many OAuth-related errors follow similar patterns for most integrations. Here are some steps to consider:

1. Check Your OAuth Credentials and Scopes

Often a 401 error means that the credentials (client ID/secret) or the requested scopes aren’t aligned with what Wix expects. Verify that:

• You’ve correctly entered your client details in the n8n credentials.
• The OAuth scopes you’re requesting match what’s required by the Wix API.
• Your app is authorized to use the selected endpoints.

2. Verify Redirect URI and Callback Settings

Ensure that the redirect URI configured in your Wix developer app matches exactly what n8n is using. Mismatches here often trigger unauthorized errors.

3. Review Your API Endpoint and Request Parameters

Double-check that:

• The URL for the OAuth token request is correct.
• All required parameters (like grant type, scopes, state, etc.) are present and formatted correctly.

4. Consult Wix API Documentation

Since the error involves an OAuth request, it can be helpful to review the Wix API documentation. Look for any notes on:

• Specific security requirements.
• Changes to the expected authorization methods.
• Any additional headers or parameters that must be sent.

By verifying these configurations and ensuring they meet Wix’s requirements, you should be in a better position to resolve the error and successfully post your blogs from n8n to your website.
