title: Callout from trigger without using Future annotation
body: <p>At this moment I'm calling a @future method X from the Account_after_update trigger. I have to use @future annotation because X makes an external site call (just to notify account is updated). It's working fine.</p>
  
  <p>But for some reasons (please don't ask why) I have to remove @future annotation.
  And of course it will be impossible to make HTTP request from the X method (Salesforce restriction).</p>
  
  <p>Is there a way how to notify external site about account updating (and send an account ID) without using of @furure annotation? Or even without a trigger? Probably something like subscription to account_updated event.</p>
