Introduction

The T3 API allows you to talk to metrc.com with HTTP requests. Using just a metrc.com login, you can load all your Metrc data or perform compliance tasks like creating harvests, transfers, or packages.

The T3 API is completely separate from the Metrc API.

Motivation

Empower Metrc users. Metrc users should be able to easily load all their Metrc data and automate compliance tasks that otherwise would require a lot of clicking and typing.

Eliminate API restrictions. The T3 API is capable of performing any task in Metrc, including tasks that the Metrc API does not support.

Offer the best documentation. APIs are hard to use, so T3 has extremely high quality API documentation.

Support interoperability. The T3 API uses an OpenAPI specification, so tools like Postman can use the APi out of the box.

Offer beginners an on-ramp. The T3 API has a rich collection of examples showing how to use the API.

Metrc API vs T3 API

To use the Metrc API, you need the following:

  • A metrc.com login
  • A generated Metrc API key
  • A third party integrator API key
  • A Metrc Connect subscription

The Metrc API cannot perform all needed tasks for compliance purposes, and it cannot return all data that is available via the metrc.com web interface.

To use the T3 API, you need the following:

  • A metrc.com login
  • A T3+ subscription

The T3 API can perform any task that is available to you on the metrc.com web interface
