HubSpot Calling Extensions: Display Contact Names Without Full CRM API

Ever found yourself needing a specific piece of data from HubSpot without wanting to dive headfirst into the complexities of API authentication and backend management? You're definitely not alone. This is a common challenge for developers and RevOps professionals aiming to streamline their HubSpot integrations.

Recently, a fantastic discussion in the HubSpot Community shed light on just such a scenario, offering a clever solution for those integrating custom softphones with HubSpot's Calling Extensions SDK. For businesses leveraging HubSpot to manage their sales, service, and even to create free ecommerce website experiences, efficient communication tools are paramount. This article will expand on that insight, providing a comprehensive guide to enhancing your outbound calling experience.

The Outbound Calling Conundrum: Missing Contact Names

The original poster in the community thread laid out a clear problem: when integrating their custom softphone with the HubSpot Calling Extensions SDK, displaying contact names for inbound calls was a breeze thanks to the onCallerIdMatchSucceeded event. HubSpot handles the lookup, and voilà, the name appears.

However, for outbound calls initiated via click-to-dial, the onDialNumber event payload was a bit sparse. It provided crucial details like phoneNumber, objectId, objectType, and calleeInfo, but conspicuously absent were the contact's firstName, lastName, or displayName. The goal was simple: show the contact's name in the softphone UI for outbound calls, just like for inbound.

The tricky part? A strong preference to avoid the full CRM API with its OAuth requirements, token management, and backend changes. The original poster had already explored a couple of avenues:

Trying @hubspot/ui-extensions / useCrmSearch within the Calling iframe, which failed due to a lack of UI Extensions runtime.
Attempting to request data from a CRM card, but discovered no official channel exists between the Calling iframe and CRM cards due to different origins and sandboxes.

So, the question hung in the air: Was there a workaround, an undocumented field, or a trick to pass the contact name directly?

HubSpot's Official Stance and the Recommended Path

A HubSpot community member and expert confirmed that, for outbound calls, the supported approach is indeed to use the objectId (and objectType) provided in the onDialNumber event and then make a subsequent call to the HubSpot CRM API to fetch the contact or company name.

The onDialNumber payload, as confirmed, does not include fields like displayName, firstName, or lastName. While onCallerIdMatchSucceeded for inbound calls benefits from HubSpot's automatic lookup, a similar mechanism isn't yet available for outbound calls.

The Lightweight Solution: Private App Tokens for Client-Side API Calls

The good news is that avoiding the full complexity of OAuth and backend services is entirely possible. The recommended path, as suggested by a community expert, is to use a private app token directly from your iframe. This approach still leverages the CRM API but significantly streamlines the process.

Why Private App Tokens are a Game Changer

Private app tokens offer a simplified authentication method for HubSpot API access, especially when you want to keep things client-side or avoid building a dedicated backend service for token management. Here’s why they’re ideal for this scenario:

No OAuth Flow: You generate the token once in your HubSpot account, and it remains static. No need for user consent flows, refresh tokens, or complex state management.
Direct Client-Side Usage: With appropriate security considerations, you can use this token directly within the JavaScript of your Calling Extensions iframe to make API requests.
Reduced Backend Overhead: Eliminates the need for a server-side component solely for authenticating with the HubSpot API.

Implementing the Solution: Step-by-Step

Here’s how you can implement this solution to display contact names for outbound calls in your custom softphone UI:

Generate a Private App Token:
- In your HubSpot account, navigate to Settings > Integrations > Private apps.
- Click Create a private app.
- Give your app a meaningful name (e.g., "Calling Extension Contact Lookup").
- Under the Scopes tab, grant the necessary permissions. For fetching contact names, you'll need at least crm.objects.contacts.read. If you also need company names, add crm.objects.companies.read.
- Create the app and copy your token. Treat this token like a password; never expose it publicly in your client-side code without proper precautions.

Integrate into Your Calling Extension Iframe:

When your onDialNumber event fires, you'll receive the objectId and objectType. Use these to construct your API request.


HubSpot.onDialNumber((data) => {
  const { objectId, objectType } = data;

  if (objectId && objectType === 'CONTACT') {
    // Make an API call to fetch contact details
    fetch(`https://api.hubapi.com/crm/v3/objects/contacts/${objectId}?properties=firstname,lastname`, {
      headers: {
        'Authorization': `Bearer YOUR_PRIVATE_APP_TOKEN`,
        'Content-Type': 'application/json'
      }
    })
    .then(resp> response.json())
    .then(c> {
      const fullName = `${contact.properties.firstname || ''} ${contact.properties.lastname || ''}`.trim();
      console.log('Contact Name:', fullName);
      // Update your softphone UI with the contact name
      // e.g., updateSoftphoneUI({ name: fullName, phoneNumber: data.phoneNumber });
    })
    .catch(error => console.error('Error fetching contact:', error));
  } else if (objectId && objectType === 'COMPANY') {
    // Similar logic for company names if needed
    fetch(`https://api.hubapi.com/crm/v3/objects/companies/${objectId}?properties=name`, {
      headers: {
        'Authorization': `Bearer YOUR_PRIVATE_APP_TOKEN`,
        'Content-Type': 'application/json'
      }
    })
    .then(resp> response.json())
    .then(company => {
      const companyName = company.properties.name;
      console.log('Company Name:', companyName);
      // Update your softphone UI
    })
    .catch(error => console.error('Error fetching company:', error));
  }
});

Security Best Practices:

While private app tokens simplify things, remember that embedding them directly in client-side code has security implications. Consider these precautions:
- Restrict Scopes: Only grant the absolute minimum necessary permissions to your private app.
- Environment Variables/Secure Storage: For production, avoid hardcoding the token. While a private app token is less sensitive than a user's OAuth token, it still grants API access. Ideally, proxy your API calls through a small backend service that injects the token, or use secure client-side environment variables if your deployment environment supports it. For simple, internal tools, direct embedding might be acceptable, but be aware of the risks.
- Content Security Policy (CSP): Ensure your iframe's CSP is configured to prevent unauthorized data exfiltration.

Why This Matters for ESHOPMAN Users and HubSpot Operators

For businesses that rely on HubSpot for their CRM, sales, and service operations, and especially those using platforms like ESHOPMAN to create free ecommerce website solutions, seamless integrations are critical.

Faster Development Cycles: Developers can implement this functionality quickly without the overhead of building and maintaining a full OAuth integration.

Conclusion

While HubSpot's Calling Extensions SDK provides robust functionality, sometimes a little ingenuity is needed to bridge gaps in specific use cases. The community discussion highlighted a common challenge and provided a pragmatic, lightweight solution using private app tokens. By leveraging the objectId from onDialNumber and making a targeted CRM API call, you can ensure your outbound calling experience is as informative and efficient as your inbound one, all without the full complexity of OAuth.

This approach empowers HubSpot users and developers to build more integrated and user-friendly tools, ultimately contributing to a more effective sales and service ecosystem.
