Configuration in Rapidi

1. Login to MyRapidi. Navigate to the Connections page and create a new connection of type CRMODATA.
   
   The fields of the CRMODATA Connection are as follows:
   • Code: auto-populated
   • Description: - type a proper description (Example: Connection to CRM TEST Environment)
   • Authentication Type: Oauth2 (Azure AD)
   • Server Connect: Here paste the Url from the CRM environment, for example, https://domainname.crm4.dynamics.com/xxxxx
   
   

   Note that the URL from the client could be larger but you’ll need to chop it until ‘dynamics.com’ and then add ‘/api/data/v9.0/accounts’. The full server connect URL should look like this: https://domainname.crm4.dynamics.com/api/data/v9.0/accounts

   • Company: Enter Company Name (or leave it blank)
   • User Id: This is the Azure application Id (that was created in the first step)

   • Domain: This is the tenant id of the customer (can be found under Azure)
   • Resource: https://domainname.crm4.dynamics.com/
   • Metadata URL: copy from the Server Connect and remove the last /accounts and add /$metadata. The full metadata URL should look like this:
     https://domainname.crm4.dynamics.com/api/data/v9.0/$metadata
   • Use SSL: Mark it as True
