MVMNT API (1.0.0)

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.

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.

Payments
