New field in the accounts API

A new string field, “external_user_id”, has been added to the accounts API.

This new field allows third party agent app developers using the authorization key flow to assign a unique account user id string to the authorization key. This is very useful when an app makes investments on behalf of a single user that has multiple Prosper accounts.

If you make investments for a user that has multiple Prosper accounts, you’ll need a separate authorization key for each account. You can map the authorization key Prosper assigns to the account by making a call to the accounts API after retrieving an access token. Assign the string value passed back in the “external_user_id” field to the authorization key so your client knows which account belongs to the authorization key.
