Integrate order creation and price quotes via the e-Courier (e-courier.com) API

Steps

1. Request that your e-Courier account be enabled for API connectivity via the e-Courier Help Center — this is a one-time per-customer configuration step, not a public self-serve toggle.
2. Note your assigned customer-specific base URL (in the pattern https://post.[yourcompany].e-courier.com); endpoint calls are built on top of that base, not a shared public host.
3. Call the Login endpoint with a username/password to retrieve a user token (User GUID), or use a token provisioned directly to you, for use on subsequent requests.
4. Use the token to create orders, update orders, search orders/statuses, request courier price quotes, check availability, and cancel orders, choosing either JSON or SOAP/XML payloads.
5. Retrieve rich media tied to a shipment (signature images, BOL documents, continuous GPS trail data) through the same API once available.
6. For event-driven outbound updates instead of polling, use the EDI functions in e-Courier's CMS to push status changes via webhook, SFTP, FTP, or AS2.
