Hey there, let's break down what's happening here and rule out possibilities step by step—first off, a full feature ban is unlikely to be the root cause here. Most of the time, these errors tie back to authentication missteps or invalid request setup. Let's walk through the most common fixes:

1. Fix the 401 Unauthorized Error in Your App #

This error almost always points to authentication issues, not an outright ban:

• Double-check your access token: Pinterest access tokens have expiration dates—head to your app dashboard to confirm yours is still valid. If it's expired, use your refresh token to generate a new one.
• Verify scopes: Make sure your token has the exact scopes required for the endpoint you're calling. For example, creating pins needs the pins:write scope; missing this will trigger a 401 even with a valid token.
• Check app status: If your app is still in "draft" mode, it has limited API access—publish it to unlock full functionality.

2. Resolve the API Explorer "Something went wrong, are your fields correct?" Error #

This message is often a red herring, tied to either authentication glitches or malformed requests:

• Re-authenticate the Explorer: Log out of the Pinterest Developer Portal, clear your browser cache, then log back in and re-authorize the API Explorer with your app. Stale sessions can cause weird authentication hiccups.
• Validate request fields: Pinterest's API is strict about required parameters and formatting. For example, when creating a pin, you must include link, title, and a publicly accessible image_url. Cross-check the endpoint's docs to ensure you're not missing mandatory fields or using invalid formats.
• Test with a minimal request: Strip your request down to only the required fields. If that works, add parameters one by one to pinpoint which one is causing the error.

3. When to Suspect a Restriction or Ban #

If you've tried all the above and still can't get access, a restriction might be on the table:

• Check your app dashboard: Pinterest will notify you directly there if your app has been restricted for violating their Developer Terms of Service.
• Review API usage: Repeatedly hitting rate limits or sending spammy/violating requests can lead to temporary or permanent restrictions. Check the rate limit headers in your API responses to see if you're exceeding limits.

If none of these steps resolve your issue, reach out to Pinterest Developer Support through your app dashboard—they can provide specific details about any account or app restrictions.
