In most cases, FlexPay Client Success Managers will set up the FlexPay MIDs on sticky.io (formerly Limelight) for you (clients). To do so, you (client) must provide credentials for the CSM to access the account. Unfortunately, there are times when the credentials provided do not grant access and the CSM is unable to log in to setup the MIDs.
