Thanks for using Backtrack. If you have any comments, suggestions or questions just let me know.
A few facts about Backtrack…
There is a rate limit enforced on the service side, not on Rapid. I can adjust on request.
The core of this service is based on Backtrack Slack Bot and has been in use since 2016. This API is new and separate from that deployment.
There is a simple Telegram Bot using this service @TrackShipmentsBot. The bot has its own route to the API and so will not count against your Rapid quota.
Work in flight includes notifications through webhooks, white box tracking page for individual shipments, and a site to manage and report on shipments.
