Hello friends, today we will discuss the Invocable Method in Apex Salesforce. We use @InvocableMethod annotation on the apex method to invoke this method from the process builder. Without @InvocableMethod annotation, we can’t access the apex method in process builder.
Check this Wrapper class Datatable in LWC Salesforce
Invocable Method Snippets :
public class InvocableCtrl {
@InvocableMethod(label='Update Contact' description='Update the list of contacts')
public static void updateData(List<Id> contactIds) {
}
}
Highlights Points :
- We can use only one @InvocableMethod annotation per class.
- The invocable method must be static and public or global, and its class must be an outer class
- Method should only one parameters
- We can’t use other annotations with the InvocableMethod annotation.
Let’s start with an example :
Step 1: Create an Apex class to update the account name when the Account is inserted.
public class InvocableCtrl {
@InvocableMethod(label='Update Account' description='Update the list of accounts')
public static void updateData(List<Id> accountIds) {
List<Account> accList = new List<Account>();
for(Account acc : [SELECT Id, Name FROM Account WHERE ID IN :accountIds]){
Account ac = new Account();
ac.Id = acc.Id;
ac.Name = ac.Name + '-' + 'Household';
accList.add(ac);
}
if(!accList.isEmpty()){
update accList;
}
}
}
Step 2: Create a Process Builder, click Setup > Process Builder > New

Step 3: Add Object Account and Set execution when only when a record is created

Step 4: Set Criteria, in my case I chose No criteria -just execute the action

Now Activate the process builder and test the full process by creating an account record and checking account name with household postpend.
