Hey Darby! Thanks for the Loom - super helpful to see what's happening. Looks like Zapier is having trouble validating the connection. This usually comes down to either auth caching on Zapier's end or something with how the API key is being sent. Quick things to try: • Remove and re-add the entire Gamma action step (not just reconnect the API key) • Try the connection in a brand new Zap to see if it's workflow-specific • Open browser console (F12), try connecting again, screenshot any errors What would help me debug: • Error messages from Zapier's task history for this Zap • The exact error text when it fails (looked generic in the video) • Does this happen in other Zaps or just this one? One sanity check - your subscription is still active at https://gamma.app/settings/billing right? Just ruling out if there was a payment hiccup since that can temporarily block API access. My theory: Since you're using agent mode, it might be auto-firing multiple requests during testing. If those hit errors, could be triggering rate limits or some protection on our end. Or Zapier changed something that's clashing with cached auth data. Let me know what you find!

Thanks Max J. it appears that removing it entirely from the automation then re-adding it did the trick. I also noticed a few of the updates like Themes from a dropdown and Folders are now there so it might have been an issue from an update on Zapier / Gamma since I think there was an updated in the last couple days which would make sense. Thanks for the support!

We did update our Zapier integration to be fully compatible with our 1.0 API (more details to come soon) so that could be apart of it. I am glad to hear you were able to get it to work! Have a good 🦃 if you celebrate.
