Hi, 
My requirement is that when an account is created in the Salesforce dashboard, I need to make a rest call-out to an external service to post the account details. 
For this, I have created a trigger with after insert / after update that calls the appropriate apex class (which makes rest callout).
Can someone please confirm if I am going in the right direction?
Any template or reference code for performing this would be very helpful.
Thanks and regards.
