The Challenge: Accessing User Phone Numbers Programmatically

A user in the HubSpot Community recently encountered this exact challenge. They were looking for a reliable method to retrieve user and owner phone numbers using the HubSpot API. While HubSpot offers a wealth of data through its API, pinpointing the correct endpoint and properties can sometimes be tricky.

The Solution: Leveraging the CRM Objects API

The good news is that accessing user phone numbers programmatically is indeed possible! The key lies in utilizing the CRM Objects API, specifically the endpoint designed for users:

/crm/v3/objects/users

This endpoint provides access to a wealth of information about users within your HubSpot account. By making a request to this endpoint and specifying the hs_main_phone property, you can retrieve the phone numbers associated with those users.

A Step-by-Step Guide to Retrieving User Phone Numbers

Here's a detailed breakdown of the steps involved:

Authentication: Before you can access any data through the HubSpot API, you'll need to authenticate your application. This typically involves obtaining an API key or setting up OAuth 2.0 authentication. Refer to the HubSpot developer documentation for detailed instructions on authentication.
Construct the API Request: Send a GET request to the /crm/v3/objects/users endpoint. To retrieve the phone number, you'll need to include the hs_main_phone property in the properties query parameter.
Specify Properties: The properties parameter allows you to specify which properties you want to retrieve for each user. To get the phone number, include hs_main_phone. For example:
```
/crm/v3/objects/users?properties=hs_main_phone
```
You can also retrieve other user properties simultaneously by adding them to the properties parameter, separated by commas. For example, to retrieve the user's first name and phone number, you would use:
```
/crm/v3/objects/users?properties=hs_main_phone,firstname
```
Handle Pagination: The CRM Objects API returns results in pages. If you have a large number of users, you'll need to handle pagination to retrieve all the results. The API response will include a paging object that contains information about the next page of results. Use the after parameter to retrieve subsequent pages.
```
/crm/v3/objects/users?properties=hs_main_phone&after=[pagination_token]
```
Parse the Response: The API will return a JSON response containing an array of user objects. Each object will include a properties object that contains the requested properties, including hs_main_phone, if a phone number is associated with that user.

Example API Response

Here's an example of what the API response might look like:


{
  "results": [
    {
      "id": "12345",
      "properties": {
        "hs_main_phone": "555-123-4567"
      },
      "createdAt": "2023-10-26T10:00:00.000Z",
      "updatedAt": "2023-10-27T12:00:00.000Z",
      "archived": false
    },
    {
      "id": "67890",
      "properties": {
        "hs_main_phone": "555-987-6543"
      },
      "createdAt": "2023-10-27T09:00:00.000Z",
      "updatedAt": "2023-10-28T11:00:00.000Z",
      "archived": false
    }
  ],
  "paging": {
    "next": {
      "after": "[pagination_token]",
      "link": "https://api.hubspot.com/crm/v3/objects/users?properties=hs_main_phone&after=[pagination_token]"
    }
  }
}

Important Considerations

Data Privacy: Always be mindful of data privacy regulations and best practices when accessing and using user phone numbers. Ensure you have the necessary permissions and comply with all applicable laws.
Error Handling: Implement robust error handling to gracefully handle potential API errors, such as invalid API keys or rate limits.
Rate Limits: Be aware of HubSpot API rate limits and design your integration to avoid exceeding them. Implement caching and other optimization techniques to minimize the number of API requests.

Extending the Solution: Beyond Phone Numbers

The CRM Objects API is a powerful tool for accessing a wide range of data within HubSpot. You can use it to retrieve information about contacts, companies, deals, and other CRM objects. By combining this data with other systems, you can create powerful integrations and automate complex workflows. For example, you could use this to build a Shopify alternative storefront using HubSpot data.
