Metrc

METRC allows API access to their systems. Each vendor must be validated, for each region. Some regions, such as Alaska allow vendors to simply sign the agreement and are enabled -- provided they've passed the validation in another METRC State. It seems that only Colorado and Oregon environments provide a test-sandbox.

This API is REST-like, pull the index of objects, pull a specific object. One caveat to note is that on write, when objects are created, the response is empty -- no information about the created resource is provided. A similar caveat exists on update, which can be mitigated by a post update read request (write/re-read).
