Review Zapier Functions logs

You can review logs for any tests and runs of your functions. This helps you understand if your code is working as expected and find errors.

Beta

This product is in open beta. It’s available for use but still in active development and may change.

Check logs for live runs

If your function has been deployed, you can find logs for past runs in the Runs menu.

To display logs of a function run:

1. From the Functions home, select the function.
2. Click the Runs icon on the left. A sidebar will open.
3. From the list, select the run (identified by date, time, and function version) you want to review. A Run details sidebar will open on the right, displaying the logs for that specific run.

Tip

You can also see all test run logs in the Runs menu on the left side.

Check logs during development

You can check logs while writing code by testing your function. To display logs for function tests:

1. From the Functions home, select the function.
2. Click the Logs tab in the right sidebar.
3. Click Run function. Logs will appear once the test has run.
