Token Exchange

This page describes how to request a token exchange. These authentication tokens should be used when making api requests for a single user.

Exchanging Tokens Using The API

Once a valid token has been obtained using the Authentication API, a limited scope token can be obtained using the token exchange API. This token can be used to make requests for a specific customer, and is safe to send to the client application/web browser as needed.

To request a token exchange send a POST to our auth server containing the access_token and requested scope.

Here’s what a successful response looks like:

1{
2    "token_type": "Bearer",
3    "expires_in": 3600,
4    "access_token": "[scoped access token]",
5    "scope": "api:credit-insights:read api:profile:read api:write",
6    "issued_token_type": "urn:ietf:params:oauth:token-type:access_token"
7}

Notes:

  • The audience must be for the correct Environment.
  • The upwardli_customer_id is the Upwardli id that you get from the Customer.created webhook.
  • The new access token is a significantly longer string than the original access token.
