MVMNT API (1.1.0)

The MVMNT API enables you to automate freight brokerage workflows by integrating directly with our Transportation Management System.

Postman setup guide: API Clients.

Authentication

OAuth 2.0 client credentials flow. See Authentication Guide for details.

Token Endpoint

POST https://api.mvmnt.io/oauth2/token

Request

Headers:

Content-Type: application/x-www-form-urlencoded

Body Parameters:

grant_type=client_credentials
client_id=YOUR_CLIENT_ID
client_secret=YOUR_CLIENT_SECRET

Example Request

curl -X POST https://api.mvmnt.io/oauth2/token \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=client_credentials" \
  -d "client_id=YOUR_CLIENT_ID" \
  -d "client_secret=YOUR_CLIENT_SECRET"

Success Response

Status: 200 OK

{
  "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...",
  "token_type": "Bearer",
  "expires_in": 3600
}

Response Fields:

  • access_token: JWT Bearer token to use for API requests
  • token_type: Always Bearer
  • expires_in: Token lifetime in seconds (3600 = 1 hour)

Idempotency

Mutating requests (POST, PATCH, DELETE) accept an optional Idempotency-Key header (up to 255 characters). Retrying a request with the same key and the same body returns the original result instead of repeating the operation; reusing a key with a different body fails. Keys are scoped to your organization — keys chosen by other tenants can never collide with yours. Use a stable identifier from your system (for example your own record id plus the action) rather than a random value per attempt.

Apply credit to invoice

Request

Not available as a standalone operation; returns 501.

A credit memo is applied as part of a payment, the same way the TMS applies it: send it in creditApplications on POST /payments, together with the invoices in applications. The credit is spread over those invoices in order, each absorbing up to its own applied amount. The total credit cannot exceed the total applied to invoices.

Reference Data

Read-only catalogs (equipment, charge codes, special requirements) referenced by id from other resources.

Every catalog also answers on its short top-level path, so GET /v1/charge-codes and GET /v1/reference-data/charge-codes are the same endpoint. The documented /reference-data/* form is canonical — it keeps the catalogs grouped here as more are added (port codes, cities, zip codes) — and the short form is a convenience alias.
