Submit Touchpoints forms from NPS mobile apps

This is a new user request from the National Park Service mobile apps team. We have an installed base of about 3.5M users and many use the app offline in National Parks. We're requesting the Touchpoints API be expanded to allow our mobile apps to POST to Touchpoints using an auth API key. The following describes a typical user scenario:

1. I open the NPS mobile app and navigate to any screen.
2. At the bottom of the view, I see a clear option to leave feedback.
3. I tap the feedback option, and a text field appears.
4. I type in my comments or suggestions.
5. I press Submit.
6. If I am connected to the internet, the app immediately sends my feedback to the National Park Service via the Touchpoints API.
7. If I am offline, the app securely stores my feedback locally.
8. When my device reconnects to the internet, the app automatically sends the stored feedback in the background, without me needing to take further action.
9. I receive confirmation that my feedback has been submitted successfully.
