GPA orders begin in the PENDING state and remain that way for the duration of the configured funding time. The default funding time is three days.
Once the GPA order has transitioned to the COMPLETION state, it will be unloadable.
If you attempt to unload a GPA order in the PENDING state, you will receive this message:
{'error_message': 'The order token is not a valid GPA load token', 'error_code': '400429'}
