Third-Party Application Declaration

A three-part, step-by-step guide to building the declaration solution in Power Apps: a multi-record form writing to the 3rd party inventory SharePoint list, with validation, a confirmation popup, and an IAM email notification via Power Automate.

Work through the parts in order — each ends with a checkpoint that proves the build is ready for the next.

1 Foundations: the list, the app, and the multi-row form

Check the SharePoint list, create the app, and build the add/delete multi-row form on the write-back architecture — ending with a smoke test that proves rows never lose data.

Steps A1–A10 2 Guidance, validation, and error messaging

Placeholder help text on every field, the mandatory-field validation gate, red-border highlighting, and per-row error messages that clear live as users fix them.

Steps B1–B9 3 Confirm, submit, notify, and ship

The confirmation popup, the one-transaction submit into SharePoint with audit stamping, the IAM notification flow, an end-to-end test script, and publishing.

Steps C1–C9
Before you startWherever a step shows <YOUR-SITE-URL> or <IAM-DL-EMAIL>, substitute your own SharePoint site URL and the IAM distribution list address. Each part tracks its own progress on this device — you can close the page and pick up where you left off.
