Build webhooks into your private app to subscribe to events occurring in the account.
In this guide, learn about:
- Defining webhook subscriptions
- Subscription types
- Response payloads
- Updating your private app configuration to point to your webhooks JSON file
- Viewing webhook subscriptions in HubSpot
Webhook subscriptions are defined in the webhooks.json
file within a webhooks
folder in the same directory as your app (e.g., src/app
). You'll also need to update your app.json configuration file to reference that file.
The webhooks.json
file contains fields for defining the webhook's settings and event subscriptions.
// Example webhooks.json
{
"settings": {
"targetUrl": "https://example.com/webhook",
"maxConcurrentRequests": 10
},
"subscriptions": {
"crmObjects": [
{
"subscriptionType": "object.propertyChange",
"objectName": "contact",
"propertyName": "firstname",
"active": true
},
{
"subscriptionType": "object.creation",
"objectName": "contact",
"active": true
}
],
"legacyCrmObjects": [
{
"subscriptionType": "contact.propertyChange",
"propertyName": "lastname",
"active": true
},
{
"subscriptionType": "contact.deletion",
"active": true
}
],
"hubEvents": [
{
"subscriptionType": "contact.privacyDeletion",
"active": true
}
]
}
}
Parameter | Type | Description |
---|---|---|
settings | Object | An object that specifies your webhook settings, including targetUrl and maxConcurrentRequests . |
targetUrl | String | The URL that webhooks will be sent to. Learn more about the response payload sent with the POST request. |
maxConcurrentRequests | String | The maximum number of concurrent requests that will be sent. |
subscriptions | Object | An object that specifies the webhook subscriptions. |
crmObjects | Array | An array containing event subscription definitions. This is the standard array to include, and should be used for all events in the new format (object.* ). Classic webhook subscription types should instead be included in legacyCrmObjects and hubEvents arrays, depending on the event. See subscription types for more information. |
subscriptionType | String | The type of event being subscribed to. Learn more about subscription types. |
objectName | String | The CRM object being subscribed to. |
propertyName | String | The property on the CRM object being subscribed to. |
active | Boolean | Whether webhooks will be sent for this subscription. |
legacyCrmObjects | Array | An array containing classic subscription types, such as contact.creation and deal.deletion . See the webhooks API guide for more information. |
hubEvents | Array | An array containing the classic subscription types contact.privacyDeletion and conversation.* . See the webhooks API guide for more information. |
Private apps built with projects use generic webhook subscription syntax, using the format object.*
rather than specifying the object name in the subscription type (e.g., contact.*
).
Subscription type | Format |
---|---|
Creation | object.creation |
Deletion | object.deletion |
Merge | object.merge |
Restore | object.restore |
Property change | object.propertyChange |
Association change | object.associationChange |
To specify the type of CRM object you're subscribing to, include the objectName
field in the subscription definition object using any of the supported objects in the table below. You'll need to include the object's corresponding scopes in your app.json
file.
appointment | fee | quote_template |
call | feedback_submission | task |
cart | goal_target | tax |
commerce_payment | line_item | ticket |
communication | listing | partner_client |
company | meeting_event | lead |
contact | note | service |
course | order | subscription |
deal | postal_mail | invoice |
discount | product | user |
email | quote | partner_account |
engagement |

"subscriptions": {
"crmObjects": [
{
"subscriptionType": "object.propertyChange",
"objectName": "contact",

If you need to subscribe to classic subscription types, you can store them in the legacyCrmObjects
and hubEvents
arrays instead, depending on the type of subscription.

legacyCrmObjects | Array | An array containing classic subscription types (e.g., contact.propertyChange ). |
hubEvents | Array | An array that can contain the contact.privacyDeletion and conversation.* classic subscription types. |
When an event that the app is subscribed to occurs, the targetUrl
you specify in webhooks.json
will receive a POST
request containing JSON formatted data from HubSpot. All events will include the same base set of fields, with other fields being added depending on the event type. Learn more about parsing webhook payloads for specific event types.
Below is an example payload for propertyChange
event. This type of event contains all generic fields, plus the propertyName
and propertyValue
fields to show which property changed and the new value.

Field | Description |
---|---|
appId | The ID of your private app. This can be helpful if you have multiple private apps pointing to the same webhook URL. |
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 the event. |
portalId | The ID of the HubSpot account where the event occurred. |
occurredAt | When the event occurred as a unix timestamp (in milliseconds). |
subscriptionType | The webhook subscription type. Can be one of the following:
|
attemptNumber | Starting at 0 , which number attempt this is to notify your service of this event. |
objectId | The ID of the object that was created, changed, or deleted. For example, for a contact-related event, objectId would be the contact's ID. |
changeSource | The source of the change. This can be any of the change sources that appear in contact property histories. |
objectTypeId | The type of object that triggered the event. See the full list of object type IDs for more information. |
propertyName | The name of the property that was updated (for object.propertyChange events only). |
propertyValue | The new property value that resulted from the change (for object.propertyChange events only). |
isSensitive | Will be true if the property is a sensitive data property. |
sourceId | The ID of the source that triggered the event (e.g., a user ID if it was a user that updated the property data). |
The object.associationChange
subscription will trigger for all associations, including custom association labels. Association change events will also trigger on both incoming and outgoing association changes. This means that an object.associationChange
event defined for an objectName
of contact
will not only trigger on a CONTACT_TO_DEAL
association change, but also on a DEAL_TO_CONTACT
association change.

After you add your webhooks.json
file and configure your webhooks, you'll need to update your app.json
file to point to the webhooks JSON file.
The following app.json
file provides an example of updating the "webhooks"
field to point to your webhooks.json
file, using the file structure from the quick start guide.
