Legacy apps are still supported by HubSpot, but don’t have access to the latest app features. Learn more about the new developer platform.
Learn how to set up the User import source feature to register your public app as a data source for bulk user imports. This means customers who have installed your app in their HubSpot account can use it to bulk import users. This feature is only available for public apps.

​
Set up the User import source feature

Before you configure your app to use the User import source feature, you’ll need to set up and host two API endpoints that will accept POST requests from HubSpot when a customer who’s installed your app triggers a bulk user import. One endpoint you set up will be to return account data, while the other will return user data. The specifications for each endpoint are detailed in the sections below. Requests are sent with the HubSpot Signature. To ensure that the requests that are received are from HubSpot, they can be validated using the signature: https://developers.hubspot.com/docs/api/webhooks/validating-requests

​
Endpoint to return account data

The URL of the endpoint that returns account data should be structured like https://BASE_PATH_OF_YOUR_SERVICE/feature/USER_IMPORT/event/FETCH_ACCOUNTS. HubSpot wil provide the following fields in the body of the request: 
// Example request body HubSpot will send to your hosted service
{
  "portalId": 10,
  "appId": 20
}
The response you return when HubSpot makes a POST request to the endpoint should be a JSON-formatted object with the following fields: 
{
"portalId": 10,
"appId": 20,
"eventType": "FETCH_ACCOUNTS",
"payload": {
"accounts": [
{
"id": "testId1",
"name": "testAccount1"
},
{
"id": "testId2",
"name": "testAccount2"
}
]
}
}

Endpoint to return user data

The URL of the endpoint that returns account data should be structured like https://BASE_PATH_OF_YOUR_SERVICE/feature/USER_IMPORT/event/FETCH_USERS. HubSpot will provide the following fields in the body of the request: 
// Example request body that HubSpot will send to your hosted service
{
"portalId": 10,
"appId": 20
}
The response you return when HubSpot makes a POST request to the endpoint should be a JSON-formatted object with the following fields: 
{
"portalId": 10,
"appId": 20,
"eventType": "FETCH_USERS",
"payload": {
"users": [
{
"id": "testUser1",
"email": "testuser1-invalid@hubspot.com",
"firstName": "Test",
"lastName": "User-One",
"existingUserId": null
},
{
"id": "testUser2",
"email": "testuser2-invalid@hubspot.com",
"firstName": "Test",
"lastName": "User-Two",
"existingUserId": null
},
{
"id": "testUser3",
"email": "testuser3-invalid@hubspot.com",
"firstName": "Test",
"lastName": "User-Three",
"existingUserId": null
}
]
}
}
Once you’ve set up your two endpoints, you can configure your app settings.
  • In your app developer account, navigate to apps in the main navigation bar.
  • Click the name of the app.
  • In the left sidebar, click More features.
  • In the Target URL section, enter the URL that HubSpot will make a POST request to when events trigger. Or, use this testing URL: https://api.hubspot.com/integration-components-example/v1/sample-app-webhooks/beta-app
  • Click to toggle the User import source switch on.
  • Click Save changes.
