Implementation

Classic

To create a new Apex class, access Setup in SalesForce, and type in "Apex" in the quick search box. 

Select "Build ... Develop ... Apex Classes".

Lightning

Access Setup, and search for "Apex" in the search box.

Classic and Lightning

Create a new class. Add the following code:

Sample Apex
@RestResource(urlMapping='/jtelACD/createCallback')
global with sharing class JTELACD_CreateCallback {
      
          
    public class JTELCallback {
        public Integer  ID;
        public Integer  AcdEventsID;
        public String   Caller;
        public String   CallbackNumber;
        public String   ServiceNumbersNumber;
        public String   ServiceNumbersName;
        public Integer  AcdGroupsID;
        public String   AcdGroupsName;
        public String   AcdGroupsForeignSystemID;
        public String   dtCallStart;
        public String   dtCallEnd;
        public String   Subject;
        public String   Body;
        public Integer  CreatingUsersID;
        public String   CreatingUsersUID;
        public String   CreatingUsersNickName;
        public String   TargetUsersID;
        public String   TargetUsersUID;
        public String   TargetUsersNickName;
        public String   SalesforceId;
        public Integer  SalesforceQueryResult;
    }
      
    @HttpPost
    global static void doPost() {
        RestRequest req = RestContext.request;
        RestResponse res = RestContext.response;
  
        try {
            // Deserialize the JSON
            JTELCallback callback = (JTELCallback) System.JSON.deserialize( req.requestBody.toString(), JTELCallback.class );
            res.statusCode = 200;
            Case newCase = new Case ( subject = callback.Subject,
                                      ContactId = callback.SalesforceId,
                                      Description = callback.Body,
                                      SuppliedPhone = '+' + callback.CallbackNumber );
            insert newCase;
            res.responseBody = Blob.valueOf( System.JSON.serialize( newCase) );
        }
        catch( Exception e ) {
            res.statusCode = 500; // Internal server error
            res.responseBody = Blob.valueOf( e.getMessage() );
        }
    }
}

This sample class will create a Case object, and attach it to the supplied ContactId provided in the SalesforceId field. The telephone number will be added to the field SuppliedPhone.

Note: this will NOT work if the SalesforceId field is not a valid contact in your Salesforce instance. Please bear this in mind, when executing the examples below.

CURL Test

First of all, obtain an OAUTH Token, see Testing with CURL.

Next, create a file on your local disk, containing the following example Callback event data in JSON:

{
	"ID": 2496,
	"Body": "Caller: +4919998764321\nCall Start: 2021-11-07 18:38:19.031\nACD Group: Group 1 - BigShoes\nCallback Reason: Hangup in queue",
	"Caller": "+4919998764321",
	"Subject": "ACD: automatic callback (hangup in queue) for +4919998764321",
	"dtCallEnd": "2021-11-07T18:38:32",
	"AcdEventsID": 2496,
	"AcdGroupsID": 235,
	"dtCallStart": "2021-11-07T18:38:19",
	"SalesforceId": "00Q1n00000LSL4WEAX",
	"AcdGroupsName": "Group 1 - BigShoes",
	"TargetUsersID": null,
	"CallbackNumber": "+4919998764321",
	"TargetUsersUID": null,
	"CreatingUsersID": null,
	"CreatingUsersUID": null,
	"ServiceNumbersName": "Big Shoes Hotline",
	"TargetUsersNickName": null,
	"ServiceNumbersNumber": "49199510",
	"CreatingUsersNickName": null,
	"SalesforceQueryResult": 1,
	"AcdGroupsForeignSystemID": null
}


The following CURL command can be used to test this API, assuming the file created above was named: c:\temp\eventJSONData.json

CURL - getCallerInformation Test
curl.exe -L --post302 --silent -i -X POST -d '@C:\temp\eventJSONData.json' --header "Content-Type: application/json" --header "Authorization: Bearer <OAUTH_TOKEN>" --header "Connection: Close" "https://<SALES_FORCE_INSTANCE_URL>/services/apexrest/jtelACD/createCallback"
