I'm mostly a front-end developer, and a new one at that. I have a client that wants to streamline the login process from their private website to their flarum forum. the web hosting platform is not open source and doesn't offer api options for login credentials to be managed through OIDC etc... so the way I'm doing this is by creating an extension that checks the website login for the users email (because their API allows for that) and then cross checks it with the flarum to see if an account with a matching email exists and then automatically logs them into the matching email's forum account.

I mostly wrote this using ChatGPT because I dunno how to do this otherwise and I ran into a wall with debugging and need some help if anyone can. I can still log into the forum, but the admin portion now gives an error. there is also a 405 error that comes up.

ChatGPT says "After reviewing the provided information, it seems that the core issue is related to how your extension is registered and how the namespaces are resolved in Flarum."

when I give the files and share my file structure, ChatGPT can find no errors, so I'm not sure where to go.

    jgrowlow are you able to share any of the code with us? The errors you see are quite generic, they could be caused by many different things.

    Are the API errors thrown when your extension makes server-side HTTP calls to the remote API, or is it something you see client-side in your browser?

    Thanks for jumping in to help! it's a server side boot error when loading and can't find the class: Error: Class "CustomApi\Providers\CustomApiServiceProvider" not found

    What I've done so far:
    checked the file structure to make sure it's correct
    ran composer dump-autoload/cache clear
    checked autoloading in composer.json

    //--------------------------------
    //extend.php

    <?php
    use Flarum\Extend;
    use CustomApi\Controllers\LoginController;
    use CustomApi\Providers\CustomApiServiceProvider;
    
    return [
        (new Extend\Routes('api'))
            ->post('/neoncrm/login', 'neoncrm.login', LoginController::class),
    
        (new Extend\ServiceProvider())
            ->register(CustomApiServiceProvider::class),
    ];

    //---------------------------------------------
    //CustomApiServiceProvider.php

    <?php
    
    namespace CustomApi\Providers;
    
    use Flarum\Foundation\AbstractServiceProvider;
    use CustomApi\Services\NeonCRMService;
    
    class CustomApiServiceProvider extends AbstractServiceProvider
    {
        public function register()
        {
            $this->container->bind(NeonCRMService::class, function () {
                return new NeonCRMService();
            });
        }
    }

    //-----------------------------------------------
    //composer.json

    {
        "name": "custom/api",
        "description": "Custom API for integrating Flarum login with NeonCRM.",
        "type": "flarum-extension",
        "require": {

            "guzzlehttp/guzzle": "^7.0"
        },
        "autoload": {
            "psr-4": {
                "CustomApi\\": "custom_api/src/"
            }
        },
        "autoload-dev": {
            "psr-4": {
                "CustomApi\\Tests\\": "custom_api/tests/"
            }
        },
        "extra": {
            "flarum-extension": {
                "title": "Login Integration for NeonCRM",

                    "backgroundColor": "#2E86C1",
                    "color": "#FFFFFF"
                }
            }
        },
        "flarum": {
            "serviceProvider": "CustomApi\\Providers\\CustomApiServiceProvider"
        }
    }

      jgrowlow this line probably doesn't do anything. It looks like the AI might be mixing up Laravel APIs and Flarum APIs:

          "flarum": {
              "serviceProvider": "CustomApi\\Providers\\CustomApiServiceProvider"
          }

      Regarding the actual error, what is the file structure?

      The way your code is written, it's expected to be:

      - extension folder (are you working with a local composer workbench directory?)
        - composer.json
        - extend.php
        - custom_api
          - src
            - Providers
              - CustomApiServiceProvider.php

      If that's indeed your file structure, try running composer dump-autoload to refresh the Composer class mapping.

      I would recommend just using "src" instead of "custom_api/src", this would better align with how files are usually organized in a Flarum extension.

      If you don't mind the code being shared or if you are planning to open-source it anyway, I'd suggest putting the code on GitHub and share the repo link with us, so we can better understand how the extension is made.

        clarkwinkelmann Thank you so much! I've never shared on GitHub before so I'm gonna go figure out how to do that and give you guys a link! I'll send the file structure without any changes made that you recommended.
