The Job Tracking system API allows to retrieve (read-only) users, contacts, inventory, jobs, and invoices from the A-Vision Job Card Tracking system. An active Job Tracking system subscription is required in order to use the API. The Job Tracking system offers a 1 month TRIAL period, see https://www.jobcardtracking.com/
Authentication is done using the X-API-Key header. Please contact us at email@example.com to get an API key. There is a rate limit to use a fair use policy and abuse will result in blocking access to the API.
