Resume aggregation

Best practice is to use the resume endpoint to answer MFA challenges; however, MX continues to support partners who leverage the update member endpoint for this purpose. This endpoint allows you to respond to multi-factor authentication by providing answers to MFA challenges. Aggregation is automatically resumed if the correct credentials are provided in the request, i.e., if the challenges are answered correctly. A member must have a connection_status of CHALLENGED in order to successfully use the resume aggregation endpoint; a 405 Method Not Allowed error will be returned otherwise. A 400 Bad Request error will be returned if the credentials provided are invalid.
