Extending Magento API - Invalid Path

I am trying to extend the Magento API - I've followed the steps from most tutorials and have done the following. I keep getting an invalid resource path error from magenta when I try to call any of the extended api methods.

Create a Module XML descriptor in app/etc/modules called Woe_Services.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Woe_Services>
            <active>true</active>
            <codePool>local</codePool>
        </Woe_Services>
    </modules>
</config>

I created a corresponding directory structure:

-app
--code
---local
----Woe
-----Services

------etc
-------|api.xml
-------|config.xml

------Model
------- Catalog
-------- Product
--------- Attribute
---------- Api.php

My config.xml file is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Woe_Services>
            <version>1.0</version>
        </Woe_Services>
    </modules>
    <global>
        <models>
            <catalog>
                <rewrite>
                    <product_attribute_api>Woe_Services_Model_Catalog_Product_Attribute_Api</product_attribute_api>
                </rewrite>
            </catalog>
        </models>
    </global>
</config>

My api.xml file is as follows:

<?xml version="1.0"?>
<config>
    <api>
        <resources>
            <catalog_product_attribute translate="title"
                module="catalog">
                <title>Product attributes API</title>
                <model>catalog/product_attribute_api</model>
                <acl>catalog/product</acl>
                <methods>
                    <create translate="title" module="catalog">
                        <title>Create new product attribute</title>
                        <acl>catalog/product/attribute/create</acl>
                    </create>
                    <delete translate="title" module="catalog">
                        <title>Delete product attribute</title>
                        <acl>catalog/product/attribute/delete</acl>
                    </delete>
                    <addoptions translate="title" module="catalog">
                        <title>Add attribute options</title>
                        <acl>catalog/product/attribute/addoptions</acl>
                    </addoptions>
                </methods>
            </catalog_product_attribute>
        </resources>
        <acl>
            <resources>
            </resources>
        </acl>
    </api>
</config>

Finally, Api.php file is as follows:

Make sure you turn rewrite on in the server config.

If you are using soap the you are missing a critical file called wsdl.xml you need to define that module inside your module etc/ folder; the file should look something like this:

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns:typens="urn:{{var wsdl.name}}" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"

    name="{{var wsdl.name}}" targetNamespace="urn:{{var wsdl.name}}">
    <types>
        <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:Magento">

            <complexType name="TestSvcEntity">
                <all>
                    <element name="testArg" type="xsd:string" minOccurs="1" />
                </all>
            </complexType>
            <complexType name="testArrayOfString">
                <complexContent>
                    <restriction base="soapenc:Array">
                        <attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:string[]"/>
                    </restriction>
                </complexContent>
            </complexType>                        
        </schema>
    </types>
    <message name="testRequest">
        <part name="sessionId" type="xsd:string" />
        <part name="param1" type="xsd:string" />
    </message>
    <message name="testResponse">
        <part name="test_out" type="xsd:string" />
    </message>     
    <portType name="{{var wsdl.handler}}PortType">

            <input message="typens:testRequest" />
            <output message="typens:testResponse" />
        </operation>        
    </portType>
    <binding name="{{var wsdl.handler}}Binding" type="typens:{{var wsdl.handler}}PortType">
        <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />
        <operation name="test">
            <soap:operation soapAction="urn:{{var wsdl.handler}}Action" />
            <input>
                <soap:body namespace="urn:{{var wsdl.name}}" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />

                <soap:body namespace="urn:{{var wsdl.name}}" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
            </output>
        </operation>        
    </binding>
    <service name="{{var wsdl.name}}Service">
        <port name="{{var wsdl.handler}}Port" binding="typens:{{var wsdl.handler}}Binding">
            <soap:address location="{{var wsdl.url}}" />
        </port>
    </service>
</definitions>

You can always check your API http://www.yoursite.com/api/v2_soap?wsdl=1 that will show all your ip available methods.

Also check that:

1. Your model appears and is enabled under the advanced tab
2. Clear your cache
3. Depending on your server config check the /tmp folder for a cache version of the wsdl.

Let me know how it goes and if that solves the issue.

Cheers!
