Magento – Invalid api path

apimagento-1.6php-5.4phpstormsoap

I have created v1 & v2 API successfully and invoking
the all methods to fallow the Marius & Sylvain instructions.

v1 & v2 all methods are successfully running except v1: update method.

v1:
1)update ->Invalid api path Error?

can any one tell me where I went wrong?

my code is:

<?php 
//$proxy = new SoapClient('http://IPAddress/ics/index.php/api/soap?wsdl'); //edit the address and put the url to your magento here
$proxy = new SoapClient('http://localhost/ics/index.php/api/?wsdl');
try
{

$sessionId = $proxy->login("magento","magento@123");


$result = $proxy->call($sessionId,'mca.mcaMcaUpdate',array('1',array('firstname'=>'Manoj','lastname'=>'Kumar','telephone'=>'97012365478')));

print_r($result); 


$proxy->endSession($sessionId);
} catch (Exception $e) {
    echo '<h1>Error</h1>';
    echo '<p>' . $e->getMessage() . '</p>';
}

thanks in advance.

Please check the url once ... your url is

"http://localhost/ics/index.php/api/?wsdl"

but it should be

 "http://localhost/ics/index.php/api/soap/?wsdl"

Magento – How to Create Custom SOAP/XML-RPC API

You can read this. It explains a lot but it's mostly for API V1.
To show you how you can create an API I think it's better to offer an example.
Let's say you have a module named Easylife_Portfolio with an entity named Project.
For this entity you can set the name, description and status.
Here are the files you need in addition to the rest of the files (controllers, models, blocks..).
app/code/local/Easylife/Portfolio/etc/api.xml - the api declaration file.

Magento 1.6 API – Why Can’t I Access My Custom Magento API?

It's a kind of error which shows that Magento doesn't find the method of your API. So you have an issue how you define this method in the api.xml. By the way I saw several potential issues. See below

You don't need to create again the public function create in your class Course_Mca_Model_Mca_Api_V2 because you extend Course_Mca_Model_Mca_Api and this one has the same method.
Your method Course_Mca_Model_Mca_Api::create expects a string as a parameter and a string as a returned value, in your WSDL definition, you define a kind of array (which is anyway badly defined). For your test purpose and to allow you a step by step coding, do:

Replace in wsdl.xml

<message name="mcaMcaCreateRequest">
    <part name="sessionId" type="xsd:string" />
    <part name="data" type="typens:mcaMcaCreateEntity" />
</message>
<message name="mcaMcaCreateResponse">
    <part name="result" type="xsd:int"/>
</message>

With

<message name="mcaMcaCreateRequest">
    <part name="sessionId" type="xsd:string" />
    <part name="data" type="xsd:string" />
</message>
<message name="mcaMcaCreateResponse">
    <part name="result" type="xsd:string"/>
</message>

You will have to update also the wsi.xml file like you did for the wsdl.xml file
Into api.xml, you have maybe some issue too, do the following:

Replace

    <resources_alias>
        <mca>mca_mca</mca>
    </resources_alias>
    <v2>
        <resources_function_prefix>
            <mca>mcamca</mca>
        </resources_function_prefix>
    </v2>

with

    <resources_alias>
        <mca>mca_mca</mca>
    </resources_alias>
    <v2>
        <resources_function_prefix>
            <mca>mcaMca</mca>
        </resources_function_prefix>
    </v2>

Then in your test code, use the V2 Soap Version

$proxy = new SoapClient('http://localhost/ics/index.php/api/v2_soap?wsdl');
$sessionId = $proxy->login('magento', 'magento@123');
$result = $proxy->mcaMcaCreate($sessionId, 'my text test');
print_r($result);
