QuickBooks PHP DevKit connection errors

Question

I've been trying to sync QB-Web Connector but I keep receiving errors:

The first was: 'Fatal error: Class 'QuickBooks_Loader' not found', which I fixed by adding including the file location at the top of the page: include_once("$_SERVER[DOCUMENT_ROOT]/qb/QuickBooks/Loader.php");

Now I am getting the following error from the web-connector:

QBWC1012: Authentication failed due to following error message. Client found response content type of 'text/html', but expected 'text/xml'. The request failed with an empty response. See QWCLog for more details. Remember to turn logging on.

I checked all the files to be sure that the content type is text/xml, still no dice. Please help.

Answer 1

The URL you're using:

$appurl = 'https://www.domain.com/qb/QuickBooks/SOAP/Server.php';

Is not the right URL.

If you reference the quick start guide you'll note that it has to point the Web Connector to this script:

docs/example_web_connector.php

That is the script that should be in your AppURL. The example script is an actual SOAP endpoint which will allow connections from the Web Connector. You've instead pointed the Web Connector to one of the library files which does nothing on it's own, and which you shouldn't need to touch or reference anywhere.

Incidentally, this is also the reason you've had to add that include_once line as well - you won't need that if you have the Web Connector pointed to the right place.
