Receive notifications about media assets without polling the JW Platform Management API.
Webhooks allow you to automate your workflow by notifying you when specific events occur in the JWP video process.
If you are not a developer or prefer a simpler implementation, you can use Zapier to create Zaps to manage your notifications.

Available webhook events
JWP's webhooks support the following notifications.
| Webhook Event | Description |
|---|---|
| Conversions Complete | Notification sent when both the thumbnail is ready and all initial video renditions have been processed
This event is only fired for the first media upload, and not when the media's original is replaced through a reupload. Event Example |
| Live Channel is Active | Notification sent when a Live Channel enters an active state
Event Example |
| Live Channel is Idle | Notification sent when a Live Channel enters an idle state
Event Example |
| Media Available | Notification sent when media is first publishable and indexed
At this point, the thumbnail is ready, but not all video renditions, such as those with higher resolutions, may have finished processing. If your media has a publish start date in the future, no Media Available notification will be sent. Event Example |
| Media Created | Notification sent when media has been first uploaded
Event Example |
| Media Deleted | Notification sent when media has been deleted
Event Example |
| Media Reuploaded | Notification sent when a media has been reuploaded
The Media Reuploaded notification is the point at which the reupload has been initiated, not the time at which the reupload has been fully processed. You will receive Conversion Complete and Media Available notifications when conversions have been indexed and the media is first publishable. Event Example |
| Media Updated | Notification sent when a media is updated
Event Example |
| New Live Channel Created | Notification sent when a Live Channel is created
Event Example |
| Stream created | Notification sent when the Broadcast Live stream has been successfully created
Event Example |
| Stream deleted | Notification sent when the the Broadcast Live stream has been deleted
Event Example |
| Stream go live | Notification sent when the Broadcast Live stream has become available
Event Example |
| Stream transitioned | Notification sent when the Broadcast Live stream has transitioned to a new state
Event Example |
| Stream updated | Notification sent when the properties of the Broadcast Live stream have changed
Event Example |
| Thumbnail Created | Notification sent when a thumbnail is created
Event Example |
| Thumbnail Deleted | Notification sent when a thumbnail is deleted
Event Example |
| Track Created | Notification sent when a track is created
Event Example |
| Track Deleted | Notification sent when a track is deleted
Event Example |
Webhooks are enabled at the property level. So, if you have multiple properties under a single account, you will need to create webhooks for each property.
Create a webhook
In your platform or language of choice, use the following steps to create a webhook:
- Create a
POST api.jwplatform.com/v2/webhookscall. - Add your secret to the header of your
POSTcall to authenticate your request. For example, in the use case below:'Authorization: 123Four56==7123Four56==7' - Create a request body. The request body must include a
metadataobject that defines the appropriate webhook properties. - Append the query body to your
POSTrequest. - Execute the API
POSTrequest.
USE CASE: A publisher wants to automate the publishing workflow for a property whose key is
1A23bCD4. Without needing to poll JWP's API, the publisher wants to know when newly uploaded videos are ready to be published to its site.
SOLUTION: The publisher must create a webhook for the property (1A23bCD4) that subscribes to the Media Available (media_available) notification. As noted in the table at the beginning of the section, the Media Available notification event indicates when media has been indexed and can be shared.
curl -X POST https://api.jwplayer.com/v2/webhooks \
-H 'Authorization: 123Four56==7123Four56==7' \
-H 'Content-Type: application/json' \
-d '{"metadata": {"name" : "Media Available Webhook", "description": "Webhook to notify me when media is ready to be published", "webhook_url": "https://my-endpoint.com", "events": ["media_available"], "site_ids": ["1A23bCD4"]}}'
If the API call is successful, the publisher receives the following response.
{
"created": "2019-09-05T11:54:37.182547+00:00",
"id": "c0Y6ebVU",
"last_modified": "2019-09-05T11:54:37.182547+00:00",
"metadata": {
"description": "Webhook to notify me when media is ready to be published",
"events": [
"media_available"
],
"name": "Media Available Webhook",
"site_ids": ["1A23bCD4"],
"webhook_url": "https://my-endpoint.com"
},
"schema": null,
"secret": "efZQiWvaaoqx1Hpgi-hhLGInZUhWa1UyWjVaVk5ZVldoR2FVZERja3BoV0hWNE4xTjYn",
"type": "webhook"
}
Verify the authenticity of a webhook
JWP gives you the ability to verify the authenticity of a webhook. To verify that a webhook originated from JWP, JWP's webhooks use JWT encryption.
When a webhook is created, the JSON response contains a secret property. The value of the secret is the shared key used for decryption. Be sure to securely store the value of the secret. This secret is returned only in the response to the POST api.jwplatform.com/v2/webhooks call.
Incoming webhooks include a header Authorization whose value is Bearer {Token}. The token is generated by hashing the webhook payload with the shared secret.
To verify the authenticity of a webhook, use the JWT decode method. The {Token} and secret should be used as arguments in the decode method. The value returned from this method should equal the body sent in the request.
JWP's webhooks do not support a rotating webhook secret. In order to generate a new webhook secret, you must first delete the existing webhook and then, create a new webhook.
The following code example shows how this workflow might look in Python.

return jwt_payload == webhook_payload

jwt_token = parse_token_from_request(request)
# This assumes a Flask implementation, but parse JSON body
webhook_payload = json.loads(request.data)
# This represents the shared secret returned on POST /v2/webhooks
# This should be stored securely.
shared_secret = "secret!"
is_jw_webhook = verify_authenticity(jwt_token, shared_secret, webhook_payload)
if is_jw_webhook:
# Congrats it is a valid JW webhook!
process_webhook(webhook_payload)
else:
# Not a JW webhook!
return
Understand available webhooks API routes
In addition to creating webhooks, you can list, return, update, and delete webhooks.
