Hey folks, I’m stuck with a problem in n8n. I need to keep my AWS Cognito OAuth tokens fresh without doing it by hand every day. I tried making a workflow to hit the Cognito token endpoint, hoping it would update the access token on its own. But it’s not working as I thought it would.
Right now, I still have to kick off the workflow myself to get a new token. This is a real pain, and I’m looking for a way to make it happen automatically. Has anyone figured out how to make n8n handle token refreshes without needing to push any buttons? Any tips or tricks would be super helpful!
Thanks in advance for any advice you can share!
I’ve tackled this issue before, and here’s what worked for me: Set up a separate workflow dedicated to token renewal. Use the Cron node to schedule it to run a bit before your token expires. In the workflow, use the HTTP Request node to hit the Cognito refresh token endpoint, then use the Set node to update the credentials in your n8n environment variables.
One gotcha to watch out for: make sure your refresh token doesn’t expire. Some OAuth providers have separate expiration times for access and refresh tokens. If your refresh token expires, you’ll need to handle that scenario too.
Also, consider implementing error handling in your token refresh workflow. If the refresh fails, you could set up an alert (via email or Slack) to notify you, so you can intervene if needed. This approach has kept my workflows running smoothly without manual intervention for months now.
yo, i had the same issue! wat worked 4 me was using the cron node to schedule a workflow that refreshes the token automatically. set it to run like 10 mins b4 the token expires. use http request node to hit cognito and update ur creds with the set node. works like a charm, no more manual refreshes!
In my experience, a dedicated workflow for token renewal can simplify the process significantly. I solved a similar issue by creating a separate workflow that runs on a scheduled trigger set slightly shorter than the token expiry time. This workflow makes an HTTP request to the Cognito endpoint to refresh the token and securely updates the credentials used in the main workflows. By isolating the token refresh logic, the process becomes more reliable and requires no manual intervention, ensuring that authentication remains uninterrupted.
