How to set up automatic token renewal in n8n for AWS Cognito?

Hey everyone, I’m struggling with n8n and AWS Cognito OAuth tokens. Right now I have to refresh the token manually every day. It’s a pain! I tried to make a workflow in n8n to do it automatically, but it’s not working as I hoped. The workflow doesn’t seem to update the access token on its own. I still have to trigger it manually to get a new token. Does anyone know how to make this process truly automatic? I really want to avoid having to do this manually every day. Any tips or tricks would be super helpful! Thanks in advance for your help.

I’ve been in your shoes with the Cognito token renewal headache. What worked for me was setting up a cron job in n8n to trigger the token refresh workflow automatically. Here’s the gist:

  1. Create a separate workflow just for token refresh.
  2. Use the ‘Cron’ node to schedule it to run daily, about an hour before the token expires.
  3. In this workflow, use the ‘HTTP Request’ node to call Cognito’s token endpoint.
  4. Store the new token securely (I use n8n’s credentials store).
  5. Update your main workflows to fetch the token from this centralized store.

It took some trial and error, but this approach has been running smoothly for months now. No more manual refreshes! Just make sure your error handling is solid, and you should be good to go. Let me know if you need more specifics on any part of the setup.

hey, i’ve had this issue too. solution: use ‘schedule trigger’ node to run daily, then call cognito token endpoint via ‘HTTP Request’ node, and store the new token. update your workflows to use n8n’s credentials. hope that helps!

I’ve tackled this issue before, and here’s what worked for me:

Create a dedicated workflow in n8n for token refresh. Use the AWS Credentials node to store your Cognito credentials securely. Then, set up an HTTP Request node to hit the Cognito token endpoint.

The key is to use the Cron node to trigger this workflow automatically. Set it to run a bit before your token expires. In the HTTP Request node, make sure you’re passing the correct grant type and refresh token.

Once you get the new access token, use the Set node to store it in a variable. You can then use this variable in your other workflows.

This setup has been running smoothly for me for months. It takes some initial setup, but it’s worth it to avoid the daily manual refresh. Hope this helps!
