Hi all, I’m really excited to start talking about Postmaster. We are a small startup in Austin that is focused on shipping integration. With Postmaster you can be shipping packages in less than 5 minutes (from signup to your first curl against the RESTful API). You can ship/track/validate-addresses through multiple vendors, get callbacks on your shipment events, and we are working on much more. We are letting people into the beta slowly to make sure we keep response times and service levels high. Let us know if you have any shipping feature requests.
Q3: When creating a shipment, will it be possible to specify rules for the "service"? E.g. "cheapest service with delivery by X date, but no more than Y dollars."
Q4: Can carrier specific account numbers be provided for lower shipping rates (and so shipments will be tied to account for claims, etc.)?
A1: Yes, you can reference them by the carrier tracking number (although you could not void/modify a shipment that wasn't created by your carrier account).
A2: Do those have a tracking number pre-printed? If so, yes. It will also work with a UPS InfoNotice or Waybill #.
A3: Yes! We have "best-effort" functionality, it will be expanded to add more complex statements, but we currently have "Send best price from X to Y within N days."
A4: Yes, if you rate is lower than ours and you are over a certain shipping threshold.
Also, yes, we know about these:
