Handle Zoom Webhooks in a Laravel application

Zoom can notify your application of various events using webhooks. This package can help you handle those webhooks. Out of the box it will verify Zoom webhook signature of incoming requests. All valid calls will be logged to the database. You can easily define jobs or events that should be dispatched when specific events hit your app.

This package will not handle what should be done after the webhook request has been validated and the right job or event is called. You should still code up any work (eg. what should happen) yourself. For more, read on.

Before using this package we highly recommend reading the entire documentation on webhooks over at Zoom.

This package is an adaptation of absolutely amazing spatie/laravel-stripe-webhooks

Upgrade from ^1.0

If you are upgrading from previous version, please note that spatie/laravel-webhook-client has been upgraded to ^3.0 - which adds an extra field into the webhooks table. Read upgrading instructions for more details.

Installation

You can install the package via composer:

The service provider will automatically register itself.

You must publish the config file with:

This is the contents of the config file that will be published at config/zoom-webhooks.php:

In the signing_secret key of the config file you should add a valid webhook secret. You can find the secret used at [HTTP webhook signing key]().

You can skip migrating is you have already installed Spatie\WebhookClient

Next, you must publish the migration with:

After migration has been published you can create the webhook_calls table by running the migrations:

Routing

Finally, take care of the routing: At the Markerplace dashboard you must configure at what url Zoom webhooks should hit your app. In the routes file of your app you must pass that route to Route::zoomWebhooks():

I personally like to group webhooks functionality by calling domain, so I would suggest webhooks/zoom (especially if you plan to have more webhooks), but it is your app, and it is up to you.

Behind the scenes this will register a POST route to a controller provided by this package. Because Zoom has no way of getting a csrf-token, you must add that route to the except array of the VerifyCsrfToken middleware:

Alternative middleware configuration

When you have multiple webhooks for various services, defined with a simialr packages, like Stripe Webhooks and Mailgun Webhooks it may be easier to define VerifyCsrfToken middleware as:

Usage

Zoom will send out webhooks for several event types. You can find the full list of events types in Zoom documentation.

Zoom will sign all requests hitting the webhook url of your app. This package will automatically verify if the signature is valid. If it is not, the request was probably not sent by Zoom.

Unless something goes terribly wrong, this package will always respond with a 200 to webhook requests. Sending a 200 will prevent Zoom from resending the same event over and over again. All webhook requests with a valid signature will be logged in the webhook_calls table. The table has a payload column where the entire payload of the incoming webhook is saved.

If the signature is not valid, the request will not be logged in the webhook_calls table but a BinaryCats\ZoomWebhooks\Exceptions\WebhookFailed exception will be thrown. If something goes wrong during the webhook request the thrown exception will be saved in the exception column. In that case the controller will send a 500 instead of 200.

There are two ways this package enables you to handle webhook requests: you can opt to queue a job or listen to the events the package will fire.

Handling webhook requests using jobs

If you want to do something when a specific event type comes in you can define a job that does the work. Here's an example of such a job:

Spatie highly recommends that you make this job queueable to minimize the response time of the webhook requests. Asynchronous processing also allows you to handle more Zoom webhook requests and avoid timeouts. More on queues.

Verification token is located in authorization reqeust header.

After having created your job you must register it at the jobs array in the zoom-webhooks.php config file. The key should be the name of zoom event type where but with the . replaced by _. The value should be the fully qualified class name.

Handling webhook requests using events

Instead of queueing jobs to perform some work when a webhook request comes in, you can opt to listen to the events this package will fire. Whenever a valid request hits your app, the package will fire a zoom-webhooks::<name-of-the-event> event.

The payload of the events will be the instance of WebhookCall that was created for the incoming request.

Let's take a look at how you can listen for such an event. You can register your event listener in EventServiceProvider.

Here's an example of such a listener:

Spatie highly recommends that you make the event listener queueable, as this will minimize the response time of the webhook requests and allow you to consume more Zoom webhook requests while avoiding timeouts.

The above example is only one way to handle events in Laravel. To learn the other options, read the Laravel documentation on handling events.

Advanced usage

Retry handling a webhook

All incoming webhook requests are written to the database. This is incredibly valuable when something goes wrong while handling a webhook call. You can easily retry processing the webhook call, after you've investigated and fixed the cause of failure, like this:

Performing custom logic

You can add some custom logic that should be executed before and/or after the scheduling of the queued job by using your own job class. You can do this by specifying your own job class in the process_webhook_job key of the zoom-webhooks config file. The class should extend BinaryCats\ZoomWebhooks\ProcessZoomWebhookJob.

Here's an example:

Handling multiple signing secrets

Sometimes you may want the package to handle multiple endpoints and secrets. Here's how to configurate that behaviour.

If you are using the Route::zoomWebhooks macro, you can append the configKey as follows:

Alternatively, if you are manually defining the route, you can add configKey like so:

If this route parameter is present, the verify middleware will look for the secret using a different config key, by appending the given the parameter value to the default config key. E.g. if Zoom posts to webhooks/zoom/my-special-secret you'd need to add a new config named signing_secret_my-special-secret, like so:
