iOS sign in on Android redirect uri issue

[BigGiantHead]

Hi,

I started using your asset and it seems like it works well.
I managed to get the google login on Android working well.
Started implementing iOS login, and I did all the steps, but when I get to the part where I have to implement a redirect URI, I followed your instructions on how to create the server and for some reason the Apple sign in page does not use POST, but it simply uses a GET request to the URI I provided and the body/token/user info is nowhere to be found. The reacts fine to the deep link that is in your documentation.
Please advise how to proceed from here. The server is done in PHP, but I don't think that makes a big difference. I was reading Apple's documentation and they say there are multiple options on how to call the redirect URI.

Thank you in advance.

To summarize your question, are you saying that the request comes to the server as a GET, not a POST?

Is it set to http instead of https?

Hi,

Thanks for answering.
Yes, that is correct, on the server it is a GET not a POST. It is set to https, http is not allowed by Apple.

Thank you for your help.

Can you share your server source code?

Sure here it is.

    add_action( 'rest_api_init', function() {
        register_rest_route( 'api', '/applelogin', array(
            'methods' => 'GET',
            'callback' =>  'applelogin',
            'permission_callback' => function() { return true; }
        ));
    });

    function applelogin($data) {
        // Read raw POST body
        $strBody = file_get_contents('php://input');
        if ($strBody === false) {
            error_log("Failed to read request body");
            http_response_code(500);
            exit;
        }

        // Log the request body to the PHP error log
        error_log("Apple login redirect body: " . $strBody);
        
        // Send redirect with custom scheme
        header("Location: coolish://callback?" . $strBody, true, 302);
        
        exit();
    }

I had to change the 'methods' parameter to 'GET' otherwise if I use 'POST' I am getting a 404, because the Apple login page is trying to use GET. The redirect deep linking to the app works fine, but the body of the request is empty.

Hi,

Any update on this?

[coolishbee]

I don't know the exact cause. Since form_post is a fixed parameter in the SDK, I have no choice but to use post. Could you please tell me the redirect uri address? And does it match the information registered in the Apple Developer console? service id or return uri, etc.

Hi,

Here are screenshots of the setup.

Hope this helps.

Is the web server down? It's not responding. Is the certificate registered?

[BigGiantHead]

Hi,

That is weird. Something must have happened with the setup.
Can you please try with https://www.myanatomyka.com/wp-json/api/applelogin
It is still setup as GET, do you want me to change it to POST?

[coolishbee]

Yes. If you don't receive it by post, you won't be able to use it anyway.

[BigGiantHead]

Ok, I changed it to POST.
