Connect Postman to Lettermint
When New Collection fires in Postman, your agent runs List projects in Lettermint. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.
