I authorize Pabbly Support to log in to my account and make changes to the specified workflow for troubleshooting.

We have a workflow that executes automatically every few days. Recently, every time an API call is made, it is coming back with a fail (about no header in authorisation section). However, whenever we manually trigger it, it works. Nothing has changed in the past few months, so I'm unsure why it's started failing.

Hello @janson ,

Thanks for sharing the details.

We checked your workflow and found that the step “API (Pabbly): Execute API Request” is failing with:

“No Authorization header found for authentication!”

This means the Authorization header is missing or not being passed during auto-execution, which is why it works manually but fails when triggered automatically.

Since this is a LeadConnector API, please use the native action “LeadConnector V2: Get Calendar”, which handles authentication automatically and is more reliable.

Please update the workflow and re-run it. Let us know if you need help.
