LemonSqueezy URL’s

Larafast comes with all URL’s pre-defined, you can find them in routes/web.php

Route::prefix('lemonsqueezy')->name('lemonsqueezy.')->group(function () {
    Route::get('subscription-checkout/{productId}/{variantId}', [LemonSqueezyController::class, 'subscriptionCheckout'])->name('subscription.checkout');
    // If your product checkout does not require auth user,
    // move this part outside "auth:sanctum" middleware and change the logic inside method
    Route::get('product-checkout/{variantId}', [LemonSqueezyController::class, 'productCheckout'])->name('product.checkout');
    Route::get('billing', [LemonSqueezyController::class, 'billing'])->name('billing'); // Redirects to Customer Portal

web.php
Route::middleware([Subscribed::class])->group(function () {
    // Add endpoints that are only for subscribed users
});

​
Customer Portal

To redirect users to their Customer Portal for Subscription and Orders management use /billing route
web.php
Route::get('billing', [LemonSqueezyController::class, 'billing'])->name('billing'); // Redirects to Customer Portal

​
Webhooks

Finally, make sure to set up incoming webhooks. This is both needed in development and production. Webhooks In Development The easiest way to set this up while developing your app is with the php artisan lmsqueezy:listen command that ships with this package. This command will setup a webhook through the Lemon Squeezy API, start listening for any events and remove the webhook when quitting the command. 
php artisan lmsqueezy:listen
Although this command should always cleanup the webhook after itself, you may wish to cleanup any lingering webhooks with the --cleanup flag: 
php artisan lmsqueezy:listen --cleanup
Currently, this command supports Ngrok and Expose. Webhooks In Production For production, we’ll need to set things manually. Go to your Lemon Squeezy’s webhook settings and point the URL to your app’s domain. The path you should point to is /lemon-squeezy/webhook by default. Make sure to select all event types.
We also very much recommend to verify webhook signatures in production.
Add LEMON_SQUEEZY_SIGNING_SECRET= in your .env file
