Custom services to run web services

D365 FO supports custom services. With a custom service, you can call application logic in D365 FO from outside D365 FO.
For Connectivity studio, a custom service is available for web services: 'BisWsServiceCall' (in service group 'BisWsWebserviceOperation').
This custom service has these service operations:

Operation	Description
executeOperation	Runs an inbound web service.
executeOperationV2	The same as 'executeOperation, but with the additional argument 'companyId'.
Ping	Tests the connection.

For these service operations, the arguments are:

Argument	Description
ProjectId	The identification of the project in Connectivity Studio.
WebServiceId	The identification of the web service in Connectivity studio.
HttpMethod	The applicable HTTP action. The HTTP action can be Get, Post, Create, Delete, Put, or Post or put.
UserName	The name of the external web service user as defined in Connectivity studio.
Url	The URL of the web service action is used to find the applicable argument values, if arguments are used.
Content	The body content if the HTTP action is not Get.
companyId	The applicable company ID in the D365 FO environment. Note: This argument only applies to the 'executeOperationV2' operation. For the 'executeOperation' operation, the default company of the D365 FO user is used.

To call the webservice from outside D365 FO, use a URL like:

https://Instancename.cloudax.dynamics.com/api/services/BiswsWebserviceOperation/bisWsWebserviceCall/executeOperationV2

('Instancename' = Your D365 FO instance identification)

Make sure to call the custom service operation with the arguments. So, the call must include the value for each of the used arguments.
