Hi Pabbly team,

I am experiencing a recurring issue with my Notion connection in Pabbly Connect and would like some help troubleshooting it.

I’m using Pabbly Connect to send data from a webhook to Notion.

Every few days I receive an email from Pabbly that a task failed with the following error (excerpt):

• status: 401
• code: unauthorized
• message: API token is invalid
• OAuthException > error: invalid_grant
• OAuthException > error_description: Invalid refresh token

After that, I log into Pabbly, open the Notion step, update/reconnect the Notion connection once, and everything works again for a while. Then, after a few days, the same error appears again.

My questions:

1. Is this a known issue with the Notion integration or OAuth handling?
2. Is there a permanent fix so that I don’t have to manually re-authorize Notion every few days?
3. Is there a recommended best practice for keeping a Notion connection stable across multiple workflows (without recreating the connection and updating every single workflow)?

Any guidance or a workaround would be greatly appreciated.
If you need more details (Task History ID, timestamps, screenshots), I’m happy to provide them.
