Instead of passing query string to rhoconnect server, you can store those value in redis during initial sync(which you will trigger after successfully loggedin using doSync method). And then you can fetch it when ever its required during auto sync.
Kindly find the store API documentation available at http://docs.rhomobile.com/en/5.1.1/rhoconnectapi/source-adapter-store-api-ruby
Thank you for the reply.
The solution suggested doesn't work in my case since values which are being sent to the server will vary since every time there would be a different person logging into the application(Login Id and the device id are being passed to the rhoconnect server currently).
Even if the values are stored in the redis server , there is no way for auto sync to know which user id and which device id to be fetched from the redis server since there is no field on which it can identify this.
Hope the explanation was clear enough.
