Building a webhook endpoint

    Receive events on your local test environment to build your integration.

    With the Stripe CLI you can have events triggered on your Stripe account sent to your local environment and then forwarded on to your application. This helps you easily test a webhook integration without needing to deploy your application or figure out how to open up your local environment to the public internet in order for Stripe to communicate to it.

    Create a webhook endpoint

    Webhook data is sent as JSON in the POST request body. The full event details are included and can be used directly, after parsing the JSON into an Event object.

    Creating a webhook endpoint on your server is no different from creating any page on your website. With PHP, you might create a new .php file on your server; with a Ruby framework like Sinatra, you would add a new route with the desired URL.

    require 'json' # Using Sinatra post '/webhook' do payload = request.body.read event = nil begin event = Stripe::Event.construct_from( JSON.parse(payload, symbolize_names: true) ) rescue JSON::ParserError => e # Invalid payload status 400 return end # Handle the event case event.type when 'payment_intent.succeeded' payment_intent = event.data.object # contains a Stripe::PaymentIntent # Then define and call a method to handle the successful payment intent. # handle_payment_intent_succeeded(payment_intent) when 'payment_method.attached' payment_method = event.data.object # contains a Stripe::PaymentMethod # Then define and call a method to handle the successful attachment of a PaymentMethod. # handle_payment_method_attached(payment_method) # ... handle other event types else # Unexpected event type status 400 return end status 200 end
    import json from django.http import HttpResponse # Using Django @csrf_exempt def my_webhook_view(request): payload = request.body event = None try: event = stripe.Event.construct_from( json.loads(payload), stripe.api_key ) except ValueError as e: # Invalid payload return HttpResponse(status=400) # Handle the event if event.type == 'payment_intent.succeeded': payment_intent = event.data.object # contains a stripe.PaymentIntent # Then define and call a method to handle the successful payment intent. # handle_payment_intent_succeeded(payment_intent) elif event.type == 'payment_method.attached': payment_method = event.data.object # contains a stripe.PaymentMethod # Then define and call a method to handle the successful attachment of a PaymentMethod. # handle_payment_method_attached(payment_method) # ... handle other event types else: # Unexpected event type return HttpResponse(status=400) return HttpResponse(status=200)
    $payload = @file_get_contents('php://input'); $event = null; try { $event = \\Stripe\\Event::constructFrom( json_decode($payload, true) ); } catch(\UnexpectedValueException $e) { // Invalid payload http_response_code(400); exit(); } // Handle the event switch ($event->type) { case 'payment_intent.succeeded': $paymentIntent = $event->data->object; // contains a \Stripe\PaymentIntent // Then define and call a method to handle the successful payment intent. // handlePaymentIntentSucceeded($paymentIntent); break; case 'payment_method.attached': $paymentMethod = $event->data->object; // contains a \Stripe\PaymentMethod // Then define and call a method to handle the successful attachment of a PaymentMethod. // handlePaymentMethodAttached($paymentMethod); break; // ... handle other event types default: // Unexpected event type http_response_code(400); exit(); } http_response_code(200);

    Listening and forwarding events

    The Stripe CLI provides a quick way for you to see events being created on your account. With the CLI you can get a look behind the scenes at all the events that will be sent to you:

    stripe listen Ready! Your webhook signing secret is {{SIGNING_SECRET}} (^C to quit)

    In a new tab, run:

    stripe trigger payment_intent.created

    Going back to the tab with listen running, you should see the event coming in:

    stripe listen Ready! Your webhook signing secret is {{SIGNING_SECRET}} (^C to quit) 2019-09-24 11:01:22 Received: payment_intent.created [evt_1FMIKEByst5pquEtW2TQHNP6]

    Once you’ve seen events coming into the CLI you can start forwarding them to your application. Stop the listen command with Ctrl+C and start it again with the --forward-to flag:

    stripe listen --forward-to localhost:4242/webhook Ready! Your webhook signing secret is {{SIGNING_SECRET}} (^C to quit)

    Make sure to replace localhost:4242 with the address of your development server with the appropriate path!

    When forwarding events, the CLI takes the event created by Stripe and makes a request to the URL provided, simulating a webhook request from Stripe. In the CLI, you should see a 200 status code from your server after the request is made:

    stripe listen --forward-to localhost:4242/webhook Ready! Your webhook signing secret is {{SIGNING_SECRET}} (^C to quit) 2019-09-24 11:34:54 Received: payment_intent.created [evt_1FMIqgByst5pquEtgAQ1Zreq] 2019-09-24 11:34:54 [200] POST http://localhost:4242/webhook

    The listen command lets you filter events coming in to your CLI with the --events flag. This is useful if you only care about or want to test specific events. The flag accepts a comma-separated list of events:

    stripe listen --events payment_intent.created,payment_intent.completed \ --forward-to localhost:4242/webhook Ready! Your webhook signing secret is {{SIGNING_SECRET}} (^C to quit)

    Triggering events

    The CLI ships a command called trigger that automatically creates certain event types for you. To trigger an event, run:

    stripe trigger <event_type> #OR stripe trigger payment_intent.created

    There are only a handful of events currently available, but the list is growing. To see supported trigger events, run stripe trigger --help or visit our GitHub page. If you’d like to see a new event added, open a feature request on GitHub.

    Testing new API versions

    The Stripe CLI lets you test upgrading to the latest Stripe API version without any side effects on your account. When invoking the listen command, give it the flag --latest to have events of the latest API version forwarded to you:

    stripe listen --latest --forward-to localhost:4242/webhook Ready! Your webhook signing secret is {{SIGNING_SECRET}} (^C to quit)

    Advanced usage

    Work with Connect

    In some cases, Connect events might be sent to a separate endpoint than standard account events. The CLI supports splitting these events using the --forward-connect-to flag, which operates similarly to the --forward-to flag.

    Set custom headers

    To add additional headers to the request the Stripe CLI makes, use the --headers (or --connect-headers when using `–forward-connect-to):

    $ stripe listen --forward-to localhost:4242/webhook --headers ...
    

    Use jq to parse events

    The CLI has the option to print events that come in as JSON instead of the default output. Provide the listen command with the --print-json flag to print the JSON to standard out:

    $ stripe listen --print-json
    

    Using the --print-json flag is useful if you want to work with a tool like jq to filter or manipulate the input. For example, you can display the type of all webhooks Stripe sends to you:

    $ stripe listen --print-json | jq .type
    

    Load your saved endpoints

    If you’ve already setup webhook endpoints in the Dashboard, the CLI has a flag to load and configure those endpoints for you as local forwarding. The flag is --load-from-webhooks-api and must be used in conjunction with the --forward-to flag:

    $ stripe listen --load-from-webhooks-api --forward-to localhost:4242
    

    The flag works by loading the endpoints defined in the Dashboard through our Wehooks API. It parses the path and event mapping for each defined endpoint, then appends that path to the --forward-to path provided while maintaining the event list for each endpoint.

    For example, let’s say you defined two endpoints on the Dashboard:

    1. https://example.com/webhook/charges consumes charge.created and charge.failed
    2. https://example.com/webhook/payment_intents consumes payment_intent.created

    When you invoke the CLI with --forward-to localhost:4242, the CLI inbounds events to two locations:

    1. http://localhost:4242/webhook/charges with charge.created and charge.failed
    2. http://localhost:4242/webhook/payment_intents with payment_intent.created

    Local HTTPS

    If you’re developing in a local environment that has self-signed HTTPS certificates, you can disable certificate verification with --skip-verify.
