Integration
Connect EasyPost and Rex
When New tracker update fires in EasyPost, your agent runs Create Lead in Rex, or Appraisal Created in Rex to Add address in EasyPost. 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.

Can my AI client use EasyPost and Rex without building an automation?

Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
