Hello, I am receiving the Error "system.limitexception too many future calls 51" when I Inserted 300+ records in our Org. I would like an assistance to get around this Error. I hope someone can help here.. I am new to Apex Code for Callouts.. Here's my code.


TRIGGER:

trigger SG_ContactTriggers on Contact (after insert) {

    //TriggerHandler
    TriggerHandlerREST handler = new TriggerHandlerREST();
    
    if(trigger.isAfter){
        handler.UPDATE_CONTACT_ADDRESS(trigger.new);
    }
}

And Here's my CLASS​

public class TriggerHandlerREST {
    //GET GEOCODE METHOD
    public void UPDATE_CONTACT_ADDRESS(List<contact> newContacts){
        
        List<contact> contactsToUpdate = new List<contact>();
        for(contact contacts : [select id, MailingPostalCode from contact where id in: newContacts]){
            
        	GET_GEOCODE(contacts.MailingPostalCode,contacts.id);
        
        }
    }
