Webhooks

The Webhooks API allows you to subscribe to events happening in a HubSpot account with your integration installed. Rather than making an API call when an event happens in a connected account, HubSpot can send an HTTP request to an endpoint you configure. You can configure subscribed events in your app’s settings or using the endpoints detailed below. Webhooks can be more scalable than regularly polling for changes, especially for apps with a large install base.

Using the Webhooks API requires the following:

  • That you set up a HubSpot app to use webhooks by subscribing to the events you want to be notified about, and by specifying a URL to send those notifications. See the prerequisites documentation for more details about creating an app.
  • That you deploy a publicly available and secure (HTTPS) endpoint for that URL that can handle the webhook payloads specified in this documentation.

Webhooks are set up for a HubSpot app, not individual accounts. Any account that install your app by going through the OAuth flow will be subscribed to its webhook subscriptions.

You can subscribe to CRM object events, which includes contacts, companies, deals, tickets, products and line items, as well as conversations events. 

Please note: to subscribe to conversations webhooks, you need access to the conversations inbox and messages APIs, which is currently in beta.

Scopes

In order to use webhooks to subscribe to CRM events, your app will need to be configured to require the contacts scope. Your app will need to be configured to require the conversations.readscope to subscribe to conversations events.  

These scopes must be set up before you'll be able to create any webhook subscriptions, either from your developer account in your app's settings, or when using the Webhooks API to configure subscriptions. Review the OAuth documentation for more details about scopes and setting up the authorization URL for your app.

If your app is already using webhooks, you won't be able to remove the contacts or conversations.read scope until you remove all webhook subscriptions from your app.

Webhooks settings

Please note: webhook settings can be cached for up to five minutes. When making changes to the webhook URL, concurrency limits, or subscription settings, it may take up to five minutes to see your changes go into effect.

Before setting up your webhook subscriptions, you need to specify a URL to send those notifications to. You can also adjust the event throttling limit, which is the number of concurrent requests your endpoint can handle. 

This throttle limit is a concurrency limit, so as soon as there is a response to a request, the total active requests will be reduced by one and another request can be sent. For example, if you have a limit of 1 request per 10 seconds, if 1 request is sent, HubSpot will wait for a response or for 10 seconds to pass before sending another request, which ever comes first.

Setting this limit helps HubSpot send you notifications as fast as possible without putting too much load on your API.

  • If you set this limit too low, notifications might time out if there are too many notifications sent to your API and the limit is saturated for more than a few seconds. This will result in notification delays. 
  • If you set this limit too high, you may saturate the resources available to your endpoint which could result in slow responses, notification delays, or your endpoint becoming unresponsive.

Manage settings in your developer account

 You can manage your URL and event throttling limit in your app’s configuration page in your developer account:

  • In your developer account, navigate to your App dashboard.
  • Click the name of the app you want to set up webhooks for. 
    app_id_list
  • In the left sidebar menu, navigate to Webhooks.
  • In the Target URL field, enter the URL that HubSpot will make a POST request to when events trigger.
  • Use the Event throttling setting to adjust the maximum number of events HubSpot will attempt to send.

  • Click Save

Manage settings via API

You can use the following endpoints and your developer API key to programmatically configure webhook settings for an app.

To view any webhook settings currently configured for an app, make a GET request to webhooks/v3/{appId}/settings.

You'll need to include the app ID in the request, which you can find below the name of the app in your Apps dashboard, or on the Auth tab in your app's settings.

The settings object contains the following fields:
Use this table to describe parameters / fields
FieldDescription
webhookUrl

The URL that HubSpot will send webhook notifications to. This URL must be served over HTTPS. 

maxConcurrentRequests

The concurrency limit for the webhook URL. This value must be a number greater than five. 

To make edits to these settings, make a PUT request to webhooks/v3/{appId}/settings and include the following fields in the request body:

Use this table to describe parameters / fields
FieldDescription
targetUrl

The publicly available URL for HubSpot to call where event payloads will be delivered.

throttling

Configure webhook throttling details in this object. The throttling object includes the period and maxConcurrentRequests fields. 

period

Time scale for this setting. Can be either SECONDLY (per second) or ROLLING_MINUTE (per minute).

maxConcurrentRequests

The maximum number of HTTP requests HubSpot will attempt to make to your app in a given time frame determined by period.

For example, your request might look similar to the following:

// PUT request to https://api.hubapi.com/webhooks/v3/{appId}/settings { "throttling": { "period": "SECONDLY", "maxConcurrentRequests": 10 }, "targetUrl": "https://www.example.com/hubspot/target" }

Webhook subscriptions

Once you’ve set up your webhook URL and event throttling limit, you’ll need to create one or more subscriptions. Webhook subscriptions tell HubSpot which events your particular app would like to receive.

Subscriptions apply to all customers who have installed your integration. This means that you only need to specify what subscriptions you need once. Once you've turned on a subscription for an application, it will automatically start getting webhooks for all customers that have installed your application, and your integration will start receiving webhook triggers from any new customers. 

The following subscription types are supported and can be used as the value for the eventType field when creating subscriptions via API: 

Use this table to describe parameters / fields
Subscription TypeDescription
contact.creation

Get notified if any contact is created in a customer's account.

The following conversations subscription types are available to you to subscribe to if you're using the conversations inbox and messages API, which is currently in beta

Use this table to describe parameters / fields
Subscription TypeDescription
conversation.creation

Get notified if a new thread is created in an account.

conversation.deletion

Get notified if a thread is archived, or soft-deleted, in an account.

Get notified if a thread is permanently deleted in an account.

conversation.propertyChange

Get notified if property on a thread has been changed. 

conversation.newMessage

Get notified if a new message on a thread has been received. 

For property change subscriptions, you will need to specify which property you want to be notified of. You can specify multiple property change subscriptions. If a customer's account doesn't have the property you specify in a subscription, you will not get any webhooks from that customer for that property.

Certain properties are not available for CRM property change subscriptions. These properties are:

  • num_unique_conversion_events
  • hs_lastmodifieddate

If you are using the conversations messages and inbox API, which is currently in beta, the following properties are available:

  • assignedTo: the conversation thread has been reassigned or unassigned. If the thread was reassigned, the propertyValue will be an actor ID in the webhooks payload; if unassigned, it will be empty.
  • status: the status of the conversation thread has changed. In the webhooks payload, the propertyValue will either be OPEN or CLOSED.
  • isArchived: the conversation thread has been restored. The propertyValue in the webhooks payload will always be FALSE

Create subscriptions in your developer account

You can create webhook subscriptions in your HubSpot developer account. 

  • In your HubSpot developer account, navigate to the Apps dashboard. 
  • Click the name of an app. 
  • In the left sidebar menu, navigate to Webhooks
  • Click Create subscription
  • In the right panel, click the Which object types? dropdown menu and select the objects you want to create a subscription for. 
  • Click the Listen for which events? dropdown menu and select the event types

create-contact-create-subscription

  • If you're creating a subscription for property change events, click the Which properties? dropdown menu and select the properties to listen for. 
  • Click Subscribe

The subscription will appear in your webhooks settings. New subscriptions are created in a paused state, so you will need to activate the subscription for webhooks to send:

  • In the Event subscriptions section, hover over the object type and click View subscriptions
  • Select the checkbox next to the event, then in the table header click Activate

activate-subscription

Create subscriptions via API

You can programmatically create subscriptions using the following endpoints. You will need to use your developer API key when making requests to these endpoints. 

A subscription object can include the following fields:

Use this table to describe parameters / fields
FieldDescription
id

A number representing the unique ID of a subscription. 

createdAt

The time in milliseconds when this subscription was created. 

createdBy

The user ID associated with the user who created the subscription. 

active

This indicates whether or not the subscription is turned on and actively triggering notifications. The value can be true or false

eventType

The type of subscription. The table at the start of this section includes the available subscription types. 

propertyName

The name of the property the subscription will listen for changes to. This is only needed for property change subscription types. 

Get subscriptions

To retrieve the list of subscriptions, make a GET request to webhooks/v3/{appId}/subscriptions.

The response will be an array of objects representing your subscriptions. Each object will include information on the subscription like the ID, create date, type, and whether or not it’s currently active. Here’s what an example response would look like:

// Example GET request to https://api.hubapi.com/webhooks/v3/{appId}/subscriptions [ { "id": 25, "createdAt": 1461704185000, "createdBy": 529872, "eventType":"contact.propertyChange", "propertyName": "lifecyclestage", "active": false }, { "id": 59, "createdAt": 1462388498000, "createdBy": 529872, "eventType":"company.creation", "active": false }, { "id": 108, "createdAt": 1463423132000, "createdBy": 529872, "eventType": "deal.creation", "active": true } ]

Create a new subscription

To create a new subscription, make a POST request to webhooks/v3/{appId}/subscriptions.

In the request body, you can include the following fields:

Use this table to describe parameters / fields
FieldDescription
eventType

The type of subscription. 

propertyName

The name of the property the subscription will listen for changes to. This is only needed for property change subscription types. 

active

This indicates whether or not the subscription is turned on and actively triggering notifications. The value can be true or false

You don't need to include id, createdAt, or createdBy, as those fields are set automatically.

For example, your request body may appear similar to the following: 

// Example POST request to https://api.hubapi.com/webhooks/v3/{appId}/subscriptions { "eventType":"company.propertyChange", "propertyName": "companyname", "active": false }

The eventType must be a valid subscription type as defined in the above section and the propertyName must be a valid property name. If a customer has no property defined that matches this value, then this subscription will not result in any notifications.

Update a subscription

To activate or pause a subscription, make a PUT request to webhooks/v3/{appId}/subscriptions/{subscriptionId}.

In the request body, include the following:

Use this table to describe parameters / fields
FieldDescription
active

This indicates whether or not the subscription is turned on and actively triggering notifications. The value can be true or false

Delete a subscription

To delete a subscription, make a DELETE request to webhooks/v3/{appId}/subscriptions/{subscriptionId}.

Webhooks payloads

The endpoint at the target URL that you specify in your app's webhooks settings will receive POST requests containing JSON formatted data from HubSpot.

To ensure that the requests you're getting at your webhook endpoint are actually coming from HubSpot, HubSpot populates a X-HubSpot-Signature header with a SHA-256 hash built using the client secret of your app combined with details of the request. Learn more about validating request signatures

// [ { "objectId": 1246965, "propertyName": "lifecyclestage", "propertyValue": "subscriber", "changeSource": "ACADEMY", "eventId": 3816279340, "subscriptionId": 25, "portalId": 33, "appId": 1160452, "occurredAt": 1462216307945, "eventType":"contact.propertyChange", "attemptNumber": 0 }, { "objectId": 1246978, "changeSource": "IMPORT", "eventId": 3816279480, "subscriptionId": 22, "portalId": 33, "appId": 1160452, "occurredAt": 1462216307945, "eventType": "contact.creation", "attemptNumber": 0 } ]

The request can contain the following fields: 

Use this table to describe parameters / fields
FieldDescription
objectId

The ID of the object that was created, changed, or deleted. For contacts this is the contact ID; for companies, the company ID; for deals, the deal ID; and for conversations the thread ID

propertyName

This is only sent for property change subscriptions and is the name of the property that was changed. 

propertyValue

This is only sent for property change subscriptions and represents the new value set for the property that triggered the notification. 

changeSource

The source of the change. This can be any of the change sources that appear in contact property histories. 

eventId

The ID of the event that triggered this notification. This value is not guaranteed to be unique. 

subscriptionId

The ID of the subscription that triggered a notification about the event.

portalId

The customer's HubSpot account ID where the event occurred. 

appId

The ID of your application. This is used in case you have multiple applications pointing to the same webhook URL.

occurredAt

When this event occurred as a millisecond timestamp.

eventType

The type of event this notification is for. Review the list of supported subscription types in the webhooks subscription section above.

attemptNumber

Starting at 0, which number attempt this is to notify your service of this event. If your service times-out or throws an error as describe in the Retries section below, HubSpot will attempt to send the notification again. 

messageId

This is only sent when a webhook is listening for new messages to a thread. It is the ID of the new message. 

messageType

This is only sent when a webhook is listening for new messages to a thread. It represents the type of message you're sending. This value can either be MESSAGE or COMMENT

As shown above, you should expect to receive an array of objects in a single request. The batch size can vary, but will be under 100 notifications. HubSpot will send multiple notifications when a lot of events have occurred within a short period of time. For example, if you've subscribed to new contacts and a customer imports a large number of contacts, HubSpot will send you the notifications for these imported contacts in batches and not one per request.

HubSpot does not guarantee that you'll receive these notifications in the order they occurred. Use the occurredAt property for each notification to determine when the event that triggered the notification occurred.

HubSpot also does not guarantee that you'll only get a single notification for an event. Though this should be rare, it is possible that HubSpot will send you the same notification multiple times.

Privacy compliant contact deletions

HubSpot users have the ability to permanently delete a contact record to comply with privacy laws. Learn more about performing a GDPR compliant delete.

You can subscribe to the contact.privacyDeletion subscription type to receive webhook notifications when a user performs a privacy compliant contact deletion.

Privacy deletion notifications have some special behavior:

  • A privacy deletion event will also trigger the contact deletion event, so you will receive two notifications if you are subscribed to both events.
  • These notifications will not necessarily be sent in any specific order or in the same batch of messages. You will need to use the object ID to match the separate messages.

Security

To ensure that the requests you're getting at your webhook endpoint are actually coming from HubSpot, HubSpot populates a X-HubSpot-Signature header with a SHA-256 hash of the concatenation of the app-secret for your application and the request body HubSpot is sending.

To verify this signature, concatenate the app secret of your application and the un-parsed request body of the request you're handling, and get a SHA-256 hash of the result. Compare the resulting hash with the value of the X-HubSpot-Signature. If these values match, then this verifies that this request came from HubSpot. Or, the request came from someone else who knows your application secret. It's important to keep this value secret.

If these values do not match, then this request may have been tampered with in-transit or someone may be spoofing webhook notifications to your endpoint.

Learn more about validating signature requests

Retries

If your service has problems handling notifications at any time, HubSpot will attempt to re-send failed notifications up to 10 times.

HubSpot will retry in the following cases:

  • Connection failed: HubSpot cannot open an HTTP connection to the provided webhook URL. 
  • Timeout: your service takes longer than five seconds to send back a response to a batch of notifications. 
  • Error codes: your service responds with any HTTP status code (4xx or 5xx).

Notifications will be retried up to 10 times. These retries will be spread out over the next 24 hours, with varying delays between requests. Individual notifications will have some randomization applied, to prevent a large number of concurrent failures from being retried at the exact same time.

Limits

You can create a maximum of 1000 subscriptions per application. If you attempt to create more you will receive a 400 bad request in return with the following body:

// { "status": "error", "message": "Couldn't create another subscription. You've reached the maximum number allowed per application (1000).", "correlationId": "2c9beb86-387b-4ff6-96f7-dbb486c00a95", "requestId": "919c4c84f66769e53b2c5713d192fca7" }
