Zapier errors / Auth
Authentication failed: The app returned "Invalid API Key"
Cause
The stored API key is wrong, expired, or lacks the permissions required by the action.
Fix
In My Apps, reconnect the affected app and re-enter the key directly from the source app (copy-paste to avoid stray spaces). Confirm the key was not rotated or revoked and that its scopes match the action (read-write vs read-only). If a security/firewall plugin is active (common on WordPress), temporarily disable it to rule out request blocking.
