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.

Hi, I'm unabel to do this because when I use the API action, it results in 'The token is not authorized for this scope.' error (maybe because “calendars.write” is not in your scope). So I need to do webhook method with private key instead.

Why is the authorisation header not being passed during auto execution? It worked before, it just stopped working tihs week.

Hi @janson,

Thanks for sharing the details.

Could you please confirm which type of HighLevel connection/account you have used for this request — Agency account or Sub-account (Location)?

This will help us review the authorization behavior and assist you accordingly.

I am on a sub account
