# TransactionDesk Partner API OpenAPI file: https://apidocs.lwolf.com/doc/transactiondesk-api.json ## Description This is version `2.0` of this API documentation. Last update on Aug 3, 2026. Lonewolf's TransactionDesk API for Partners to integrate with the TransactionDesk application. ## Authorization ### Authorization Code Flow 1. Redirect the user to the OAuth authorization URL: `https://api.pre.transactiondesk.com/oauth/authorize?client_id=Lonewolf&redirect_uri=https://www.example.com&response_type=code&state=active` 2. The user logs in via the Lonewolf Authentication system. 3. On success, the user is redirected back to your `redirect_uri` with a `code` parameter appended. 4. Exchange the code for an access token via `POST /oauth/token` (see Authentication section). The code is one-time-use and expires in 10 minutes. 5. Include the access token in the `Authorization: Bearer ` header on every request. ### Client Credentials Flow For enterprise integrations, use `grant_type=client_credentials`. No user redirect is required. Include an `On-Behalf-Of` header with the target user's GUID on API requests. ## Universal Global Fields Below is a list of the fields related to a transaction that can be updated through the API for the Transaction Desk System. ### 1.
