Memsource REST API

REST API Authentication

Most API calls require an authenticated Memsource user. The APIs do not use any special user accounts. Each API can be called on behalf of any existing user using their username and password.


Before calling any API that requires an authenticated user, call the auth/login API to obtain an authentication token. The token is valid for 24 hours and can be used for all subsequent calls. Do not create a new token for every call.

In subsequent API calls, the obtained token is used in the Authorization header. The header value field is introduced with ApiToken followed by a space and the token itself.

OAuth 2.0

Use OAuth 2.0 in applications instead of sending tokens with each call.

To establish the OAuth 2.0 connection, follow these steps:

  1. From the Setup Setup_gear.png page, scroll down to the Integrations section and click on Registered OAuth Apps.

    The Registered OAuth Apps page opens.

  2. Click New.

    The Create OAuth App page opens.

  3. Provide a Name, Redirect URI (Callback) and an optional Description.

  4. Click Save.

    The Registered OAuth Apps page opens with the new connection in the list and an associated Client ID.

    The ID is used in the application that connects to Memsource to establish the connection. It is stored in the Memsource database and is used to pair requests with the proper requester.

  5. Use these URLs with the generated Client ID for authorization:

    • Auth URL

    • Token URL

  6. When authorizing, use the Administrator account to log in and click Allow.

    The application is now linked with Memsource and the authentication API call will not be required.
