Sounds like you need another class to wrap that API call in.

Create a new class and make sure it's going to be autoloaded. You might need to create a classes directory and then in your global start file add the directory to the class loader.

Economic.php

<?php

class Economic {

	public function pushCustomerData()
	{
		// Place your API call in here
	}

}

Then from within your store method you can get an instance of the Economic class and call the pushCustomerData method.

$economic = new Economic;

$economic->pushCustomerData();

This is just the basic idea. You might like to create a constructor on that class to simplify a few things, especially if you have a number of API calls that you make that re-use the same connection details.

Thanks mate, got the idea.. Great input ;)
