Free Busy Custom API Google calendar doesn't work

I am trying to build a webhook automation that checks my schedule and can provide times when I am free via text message. the automation works using AI and the get all calendar events action but it is grossly token inefficient as it has to load roughly 33k tokens per run.

I tried to set up a custom API call to the free busy end point as this would require far fewer tokens. but no matter what configuration I try ( even using the custom code action) AP modifies the API call to prevent it from connecting to the free busy endpoint. Can you fix this or add a free busy action?

can you try Custom API call action of calendar piece?

I tried that first. AP edits the end point back to the default before it sends the call I can see it reflected in the testing log.

@kishanprmr any update on this?

Can you share the step configuration for the custom API call?

@kishanprmr I worked on this with Grok Here is the full thread showing the different things I tried and the errors I received https://x.com/i/grok/share/4sauEm6qIIzikbRoARFH79nYD

You can use custom API call as shown in image. You can provide items id in request body.
