I have written a callout class as below.But when a account is created/updated am getting the exception like "You have uncommitted work pending. Please commit or rollback before calling out" at 36 line(response = httpProtocol.send(request); ).But am able to see the correct ouput as I have written try , catch but the client is getting exception mails even when the output is correct.

Please help guys, would be waiting for your reply!! Appreciate the help!!

If the query in your insertFunction returns more than one Account then you wil be performing this sequence:

  • Http request
  • database update
  • HttpRequest
  • database update
  • ...

which as the error message reports is not allowed (because it would potentially leave an uncommitted transaction open for many seconds which is expensive for the platform).

If you rearrange your code to do all the Http requests first and then the updates second you should avoid this problem (though you may hit the 10 Http callouts governor limit instead).
