OAuth Token Expired: How to Reconnect Your Ad Platform

When an OAuth token expires or gets revoked, your automated relay uploads stop. Here’s how to diagnose and fix the issue quickly.

Symptoms

• Relay uploads fail with 401 Unauthorized or 403 Forbidden
• TUOCA Activity Logs show authentication errors
• Conversions stop appearing in your ad platform

Common Causes

Cause	Platform	Fix
Refresh token expired	Google (6mo unused)	Re-authenticate in TUOCA
Password changed	All	Re-authenticate
2FA updated	All	Re-authenticate
User removed from account	Google, Meta	Add user back, re-authenticate
MCC access revoked	Google	Re-link client account
App access revoked	Meta, Google	Re-authorize in TUOCA
Token manually revoked	All	Re-authenticate

How to Reconnect

Google Ads

1. In TUOCA → Settings → Destinations → Google Ads
2. Click Reconnect
3. Sign in to your Google account (the one with Ads access)
4. Click Allow to grant TUOCA permissions
5. Your relays automatically resume

Meta

1. In TUOCA → Settings → Destinations → Meta
2. Click Reconnect
3. Sign in to Facebook (the account with Business Manager access)
4. Select the business and pixel
5. Click Continue

Microsoft Ads

1. In TUOCA → Settings → Destinations → Microsoft Ads
2. Click Reconnect
3. Sign in to your Microsoft account
4. Authorize TUOCA access

TikTok

1. TikTok uses access tokens, not OAuth refresh tokens
2. Go to TikTok Ads Manager → Assets → Events → your pixel → Settings
3. Click Generate Access Token
4. Copy the new token
5. Update it in TUOCA → Settings → Destinations → TikTok

Prevention

1. Use a shared service account — Not a personal account that might be deactivated
2. Don’t change the password on the authenticating account unnecessarily
3. Monitor relay health — TUOCA alerts you to authentication failures
4. Keep access current — Ensure the authenticating user retains ad account access
