To retrieve all user records associated with your account

ResponseList list = await client.GetResponses();
//Returns a List<SecureStoreUser>


foreach(SecureStoreUser user in list.users)
{
}

The SecureStoreUser object:

SecureStoreUser
      {
        string remoteID 
        string stripeID
        string businessName
        bool accountSet 
        bool routingSet
        bool stripeSynced
        bool melioSynced 
      }

You can limit the ResponseList to only records that haven’t been synced with either Stripe or Melio

ResponseList list = await client.GetResponses(stripeNotSynced:true);

o

ResponseList list = await client.GetResponses(meliosNotSynced:true);
