We provide two examples here.
The first example queries email Task objects from the Salesforce system:
Sample Apex genericQuery
@RestResource(urlMapping='/jtelACD/getEmailTasks') global with sharing class JTELACD_GetEmailTasks { // Class to decode the parameters public class GenericQueryParams { public String Param1; public String Param2; public String Param3; public String Param4; public String Query; } @HttpPost global static String doPost() { RestRequest req = RestContext.request; RestResponse res = RestContext.response; // Deserialize the JSON (not used in this example - just for illustration purposes) GenericQueryParams genericQueryParams= (GenericQueryParams) System.JSON.deserialize( req.requestBody.toString(), GenericQueryParams.class ); // Find next task to schedule in jtel system. // Note - the exact logic of this will be dependent on the Salesforce installation - this is JUST AN EXAMPLE. List<Task> tasks = [SELECT FIELDS(STANDARD), TYPEOF Who WHEN Lead THEN FirstName, LastName, Email WHEN Contact THEN FirstName, LastName, Email END FROM Task WHERE Status = 'Inbound Email' WITH USER_MODE LIMIT 1]; if( tasks.size() >= 0 ) { return JSON.serialize( tasks[0] ); } res.statusCode = 404; return null; } }
The second example sets Task objects to "In Progress" in Salesforce:
Sample Apex genericQuery
@RestResource(urlMapping='/jtelACD/setEmailTaskStatus') global with sharing class JTELACD_SetEmailTaskStatus { // Class to decode the parameters public class GenericQueryParams { public String Param1; public String Param2; public String Param3; public String Param4; public String Query; } @HttpPost global static String doPost() { RestRequest req = RestContext.request; RestResponse res = RestContext.response; // Deserialize the JSON GenericQueryParams genericQueryParams = (GenericQueryParams) System.JSON.deserialize( req.requestBody.toString(), GenericQueryParams.class ); Task task = [SELECT FIELDS(STANDARD) FROM Task WHERE id =: genericQueryParams.Param1]; task.Status = genericQuery.Param2; update task; return System.JSON.serialize(task); } }
CURL Test
First of all, obtain an OAUTH Token, see Testing with CURL.
The following CURL command can be used to test this API:
CURL - genericQuery Test
curl --silent -i -X POST -d '{ "Param1" : "Example Param 1", "Param2" : "Example Param 2", "Param3" : "Example Param 3", "Param4" : "Example Param 4", "Query" : "Example Query" }' --header "Content-Type: application/json" --header "Authorization: Bearer <OAUTH_TOKEN>" --header "Connection: Close" "https://<SALES_FORCE_INSTANCE_URL>/services/apexrest/jtelACD/genericQuery"
