# 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.

Result: 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.

## 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.

## Prompt

```text
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.
```
