The correct use is: time_in_force='GTT', cancel_after='min'

To cancel after 2 or 3 minutes use a timer in your loop and then send a cancel message after the elapsed time. If you are getting into the fine details of time and candles then it can be helpful to use public_client.get_time() in order to get the most accurate coinbase time and build a stopwatch from that.

Also I would highly recommend using a more recent version of python!

Thanks noah222 for your prompt reply and advise. I tried it with your suggestion but still it fails. Maybe my python version is too old. I will use my self timed cancel order function. This is also more flexible in the time you would like to wait.

This is very odd. You basically only get this error if you provide the cancel_after kwarg without also providing time_in_force='GTT'

I was not able to reproduce this on my end. I copied and pasted your call and it works on my end. Are you still seeing this issue?
