Good to know:
It's only possible to choose one state per Payment Intent at a time using the test API endpoints or the Payment Window UI.
In reality, a Payment Intent always transitions from the detected state to a final one, e.g. completed. However, using the test endpoints, you can only put the Payment Intent in a single state at a time.

Your feedback is always welcome, so do not hesitate to get in touch with us if you have a suggestion for an additional Test API endpoint.
