I am using Dynamics CRM 365 trial version currently but client is having Dynamics 365 On-premise version.
Requirement: I want to use CRM 365's data into Mobile App which can consume data from Web API and will be able to fetch and manipulate the data which will reflect in CRM itself too.
What I have tried till now is created a Demo Web API which access the data from XML using oData same as which comes with Dynamics CRM SDK 365 - and it is working fine.
But for this I need to have Metadata ( Reference Link to get Metadata of CRM 365 ) which is getting too big because of unrequired data. Also I don't know that how to query (specially JOINS) using this code.
How can I access and manipulate the data easily and POST/PATCH/DELETE the manipulated data back to CRM data?
