How to setup custom api for Magento with SOAP V2?

Question

I am on Magento 1.4.1.1 and I am trying to setup a custom function in the API using SOAP v2. I have it working for SOAP v1 but I need v2 so that C# can use it. For v2 the function shows up in the WSDL but alwasy returns this error: Procedure 'testFoo' not present.

Here are my files:

/app/etc/modules/ABT_Test.xml

/app/code/local/ABT/Test/Model/API.php

<?php
class ABT_Test_Model_Api extends Mage_Api_Model_Resource_Abstract
{

    public function foo()
    {
        return true;
    }
}
?>

/app/code/local/ABT/Test/Model/API/V2.php

<?php
class ABT_Test_Model_Api_V2 extends ABT_Test_Model_Api
{
}
?>

And here is the code I use to test the API:

<?php
    $mageUser   = '########';
    $mageApiKey = '########';

    //SOAP V1
    echo "SOAP V1 <br />";
    $mageUrl    = 'http://www.########.com/api/soap/?wsdl';
    $soap = new SoapClient($mageUrl, array('cache_wsdl' => 0));

    try {
        $sessionID = $soap->login($mageUser, $mageApiKey);
        var_dump($soap->call($sessionID, 'test.foo', array()));
    } catch (Exception $e) {
        echo 'Exception: ' . $e->getMessage() . '<br />';
    }

    //SOAP V2
    echo "SOAP V2 <br />";
    $mageUrl2    = 'http://www.########.com/api/v2_soap/?wsdl';
    $soap2 = new SoapClient($mageUrl2, array('cache_wsdl' => 0));

    try {
        $sessionID2 = $soap2->login($mageUser, $mageApiKey);
        var_dump($soap2->testFoo($sessionID2));
    } catch (Exception $e) {
        echo 'Exception: ' . $e->getMessage() . '<br />';
    }
?>

I obscured the username, password and url. The function shows up in the v2 WSDL and the php code recognizes that it is in the WSDL but I still get the error: Procedure 'testFoo' not present.

So what am I missing?

EDIT: I did what Zyava suggested and it got my example working. I then copied the folder and did an exact (case sensitive) find and replace to use a meaningful Module name and function name. I was careful to pick names that I didn't think would be reserve words. On the new module the call on the v1 WSDL works fine but the v2 gives the same "Procedure 'xxx' not present" message. I then went and renamed the method on the test from 'Foo' to 'Fooz' and I got this message: "Resource path is not callable." I find it interesting that I get a different message. This leads me to believe there is some cache/configuration/something that is causing the problem. Any ideas?

Answer 1

At first I should warn you that Magento doesn't support SOAP v2 format for now, api/v2_soap/?wsdl is just second version of soap api .

1.

<models>
    <test>
        <class>ABT_Test_Model</class>
    </test>
</models>

Because you are writing module which isn't core, you should write <abt_test>

2. <model>test/api</model> . Should be <model>abt_test/api</model> in your case.

3. <acl>test/foo</acl> .

Does this acl section exist in your adminhtml.xml?

Answer 2

bygrace,

your code is so perfect!

add

 .... <resources_alias> <test>test</test> </resources_alias> ..... 

same level with

<resources> and <v2>

on Api.xml

and it'll be working good.

I has having the same issue and i tried clearing the tmp file as i had hosted it using xampp it didnt work i was getting Procedure ххх not present exception , I had to disable the cache management in the admin page of the server .
How to disable Cache in Admin page
In the admin page under the system there is a section called cache management disable everything during the development phase or else any change you do wont be reflected in the wsdl.
