Tekmetric Inventory API

openapi: 3.0.3
info:
  title: Tekmetric Appointments Inventory API
  description: Tekmetric is a cloud-based auto repair shop management platform. Its REST API is partner-gated - access requires requesting credentials at api.tekmetric.com and Tekmetric's approval (reported at roughly 2-3 weeks); there is no self-serve signup or public API reference. The endpoints, parameters, and response envelope documented here are sourced from beetlebugorg/tekmetric-mcp, an independent open-source client that holds approved credentials and calls the live API - not from an official Tekmetric API reference document. Only read (GET) endpoints are documented because that is all the reference client implements; write endpoints may exist but are not evidenced in any public source.
