If your use case requires it, you can associate users and businesses with one another by creating parent-child relationships. This relationship enables a parent user or business to monitor the spending of its children. You can optionally enable a child user to make payments using funds held by the parent’s account.
To create a child account, send a POST request to the /users endpoint that includes the token of the parent account as the value of the parent_token field.
For more information, see Users in the Core API Reference.
