Challenge
The client needed a simple, testable messaging surface without exposing provider credentials in the browser or turning a small integration into a large application.
Approach
We separated the React interface from the protected messaging endpoint, added explicit delivery states, and kept the interaction small enough for fast operator use.
What changed
- Credentials stayed on the server side.
- Operators received clear success and failure feedback.
- The integration remained easy to extend with templates and inbound events.
