Third-party token API endpoint

Devin AI planned and built a backend API endpoint for generating third-party user access tokens, then opened a GitHub pull request.

After 2-3 review rounds the PR was production-ready and merged. The task took about 1 hour versus roughly 15 minutes coding it alone.

Overview

How it was set up

Devin was given the third-party API docs, the target microservice name, and instructions to reuse the existing CDK secrets logic for the API key. Review feedback went in as GitHub PR comments.

Worth knowing

First pass missed the API key and style rules; the author fixed these in 2-3 review rounds.

A prompt to start from

Implement the backend API based on this documentation [link to third-party docs]. Add it to [microservice name]. Use the existing CDK secrets logic to store the third-party API key.
