Best method to get status?

What is the best practice to determine what the device is currently doing and/or cancel the current operation?

Here’s the scenario: User starts a checkout but closes the app (or loses connectivity etc). User immediately reopens app and attempts to do a new checkout before the prior checkout times out.

The app can start a new payment request, but it will just be pending until the previous checkout times out.

:wave: What SDK is this with? Is it Reader SDK or is it Point of Sale API? :slightly_smiling_face:

Hi Bryan,

It’s the Terminal Api (

The approach we selected was to query all checkouts for the last x minutes and cancel anything that’s IN_PROGRESS or PENDING for the specified device and that approach seems to work.

Great! Glad to hear you found an approach that fits the business need. :slightly_smiling_face:
