API changelog

Changelog

payment_method now works when confirming a booking. Previously only create accepted the flat payment_method string; confirm silently ignored it and fell back to your credit account, which surfaced as a confusing 403 NO_PAYMENT_METHOD. Both endpoints now take the same value, and it is the same id that GET /api/members/payment-methods returns.
New "credit" token — bill your credit account explicitly, instead of selecting it by leaving the field out. See how payments work.
Clearer payment errors. An unrecognised payment_method, a malformed id, or a misspelt field name (for example payment-method instead of payment_method) now returns a 400 naming the problem. Previously these were ignored and the request quietly fell through to the credit-account path.
payment_method and payment may be sent together as long as they select the same method. Naming two different methods returns a 400 rather than one silently winning.
GET /api/members/payment-methods now also returns card_id and agreement_id (v4 only), so you do not have to strip the nab_ prefix to build a confirm request. GET /api/v4/members/me/cards is accepted as an alias of the same endpoint.
New documentation — how payments work and a reference page for listing payment methods.

Terms and information-package acceptance is recorded when an API key is issued.

Developer Center rebuilt around v5, with an interactive API Explorer and the @transdirect/api-sdk TypeScript SDK. See SDKs and versioning.

@transdirect/api-sdk published, generated from the v5 OpenAPI spec.
Booking items accept an {id} path parameter, and demo confirmation behaves the same on v4 and v5.

API access is now open by default. The manual “validate your account to enable API access” step was removed. Any API key can quote immediately, and a booking goes live as soon as you can pay for it. See the access model.

Demo mode added — a flag on your normal API key that exposes a synthetic Demo courier, so you can run a full quote, book, label and track cycle with no charge and nothing shipped. See demo mode.

Multipickup upgraded to Frequent rates — discounted pricing for members shipping several parcels from the same address on the same day, on Couriers Please and Aramex.

Order boxing functionality updated — improvements to the order boxing API for better packing calculations.

Multipickup functionality added — initial release of the multipickup system for Couriers Please and Aramex, allowing discounted rates for multiple pickups from the same address on the same day.

Order boxing functionality added — new API support for consolidating multiple items into defined box sizes for more efficient quoting.
