On TinyCommand, add the Mailchimp Get List Member action to a workflow, map its 2 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

What happens if Mailchimp returns an error?

The run history shows the failed step with its input and the error message Mailchimp returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Get List Member support batch operations?

Run Get List Member inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Mailchimp's rate limits.
