Cool... Glad you solved it.

I'm having the same error. I'm doing a simple GET request in my browser to test by entering:
www.pesapal.com/API/PostPesapalDirectOrderV4?oauth_signature=q5KC%2B1dYG5HHq1iBSNEe5Ei1F3U%3D=&oauth_timestamp=1345035041&oauth_nonce=vaopfjgv3498fjua9pewr8jaa&oauth_consumer_key=Z0M7wru3yk2ZyPULg4gYj6ZRuy%2F%2FiJuQ&oauth_callback=http%3A%2F%2F127.0.0.1%3A3000%2Fuser%2Ftransaction_complete&oauth_signature_method=HMAC-SHA1&pesapal_request_data= This e-mail address is being protected from spambots.

And all that is returned to me is:
Problem: signature_invalid | Advice: > |

Is it a problem in escaping the oauth signature? How did you solve this issue?

This also happen if the $iframelink is http instead of https when you are going live

this is what it should look like

$iframelink = 'www.pesapal.com/api/PostPesapalDirectOrderV4';
not

$iframelink = 'www.pesapal.com/api/PostPesapalDirectOrderV4';

Thanks the https pointed me to the right direction... :)

Hello How did you manage to solve this problem?

am still stuck to these problem guys. am testing my application on sandbox but get the same error

While testing whether my IPN setup works, I used curl and supplied the GET parameters as required. Note: I know the url mapping to my ipn file should be triggered by pesapal. Anyhow, I used curl on my terminal to simulate pesapal. I got a response that the object had been moved to a different url. I simulated the same on a browser and on clicking the link that the object had been moved to I got the status.

Unfortunately, arriving at the status should be autonomous. What is not happening, has the php ipn file handling the ipn-listener been updated or what?

You may check the xmlhttprequest.php file attached

The XML Http Request is empty? Why?
