How can I use “json.serialize” in Apex for converting a list format into JSON?

 In the context of Salesforce, you can convert a list of “employee_ _ C” records into the format of JSON by using “json.serialize” apex for sending over a REST API callout by using the steps which are given below:-

// Step 1: Query the Employee__c records

List employees = [SELECT Id, Name, Email FROM Employee__c LIMIT 100];

// Step 2: Convert the list of Employee__c records to a JSON string

String jsonPayload = JSON.serialize(employees);

// Step 3: Make the REST API callout and include the JSON payload in the request body

HttpRequest request = new HttpRequest();

Request.setEndpoint(‘https://api.example.com/employees’);

Request.setMethod(‘POST’);

Request.setHeader(‘Content-Type’, ‘application/json’);

Request.setBody(jsonPayload);

// Step 4: Send the request

Http http = new Http();

HttpResponse response = http.send(request);

// Step 5: Handle the response as needed

If (response.getStatusCode() == 200) {

    // Success handling

} else {

    // Error handling

}
