HubSpot's Latest Developer Updates: What E-commerce & RevOps Pros Need to Know

Alright, ESHOPMAN fam! We've been keeping a close eye on the HubSpot Community, and a recent developer rollup caught our attention. While the original post was pretty technical, it's packed with crucial updates that could significantly impact how you manage your e-commerce operations, customer relationships, and overall RevOps strategy within HubSpot. Think of it as a peek under the hood of your favorite CRM, revealing new ways to optimize.

Let's break down the most important takeaways from this 'April 2026 Rollup' – especially for those of us running stores or managing complex customer journeys.

Say Goodbye to Legacy CRM Cards: Time to Migrate!

This is probably the biggest headline for anyone with custom integrations or unique data displays in their HubSpot CRM. HubSpot is deprecating Legacy CRM Cards on October 31st, 2026. That might sound far off, but trust us, you don't want to be scrambling at the last minute.

The good news? HubSpot has introduced a Legacy CRM Card View Swapping Tool. This tool allows developers (or your integration partners) to migrate those older CRM cards to the newer, more robust UI Extension App Cards without disrupting your existing customer views. This means your sales team won't suddenly lose sight of critical e-commerce data (like recent orders, customer lifetime value, or product preferences) that you've built into your contact or company records.

Why this matters for your e-commerce business: If you've got custom cards pulling in order details from your storefront, shipping info, or any other e-commerce-specific data, this migration is essential. The new App Cards offer more flexibility and a better user experience, ensuring your team continues to have all the relevant customer context right inside HubSpot.

Actionable Steps for Developers (or Your Tech Team):

The original poster outlined a clear path for migration:

  1. Prepare Your App: Upgrade to the latest HubSpot CLI and connect to your account.
    2. npm i -g /cli@latest
hs auth
  2. Migrate Your App: Ensure your app is on the Projects Framework. If not, run hs app migrate. If it's already project-based, use hs project migrate.
    3. hs app migrate
  3. Create a Replacement App Card: You have two options here: redesign from scratch using UI extension React components for full advantage, or use the Legacy Card Converter for a quicker replication of your existing card's behavior.

Important Note: If your legacy CRM card supports tickets, you'll need to create two App Cards – one for crm.record.sidebar and another for helpdesk.sidebar.

Once your replacement card is ready, you'll call the Migrate Views API. This runs asynchronously, ensuring a smooth transition for your users. The key here is proactive action to avoid any data visibility issues for your sales and service teams.

Custom Channels API Gets Smarter for Outgoing Messages

For those of you leveraging HubSpot's Custom Channels API for unique customer communication (think personalized order updates, abandoned cart reminders via custom chat, or specific support channels), this is a neat upgrade. The API now includes associateWithContactId and senderActorId for outgoing messages.

What this means for e-commerce and RevOps:

  • Better Contact Association: associateWithContactId ensures that your custom outgoing messages (like a proactive chat about a recent purchase) are correctly linked to the right contact record from the very first message. No more guessing which customer that chat belongs to!
  • Clearer Sender Attribution: With senderActorId, you can explicitly state who (or what) sent an outgoing message. Was it a support rep? An automated bot? Your e-commerce platform's integration? This creates a much clearer audit trail and context in your Conversations inbox, which is invaluable for customer service and team collaboration.

This will help you refine your customer engagement strategies, ensuring every interaction is contextualized and attributed correctly.

POST conversations/custom-channels/2026-03/123/messages
{
  "channelAccountId": 789,
  "messageDirection": "OUTGOING",
  "associateWithContactId": 54321
}
POST conversations/custom-channels/2026-03/123/messages
{
  "channelAccountId": 789,
  "messageDirection": "OUTGOING",
  "text": "Hi from our support bot",
  "senders": [
    {
      "deliveryIdentifier": {
        "type": "CHANNEL_SPECIFIC_OPAQUE_ID",
        "value": "sender-opaque-id-123"
      },
      "name": "Support Bot",
      "senderActorId": "A-1234567"
    }
  ],
  "recipients": [
    {
      "deliveryIdentifier": {
        "type": "CHANNEL_SPECIFIC_OPAQUE_ID",
        "value": "recipient-opaque-id-456"
      }
    }
  ]
}

Breeze Assistant: Your New App Discovery Sidekick

Here's a cool one for anyone looking to expand their HubSpot capabilities: Breeze Assistant can now recommend Marketplace apps based on natural language queries. You can describe a business need, like needing the "best ecommerce app maker" for your specific product type or a tool to streamline inventory, and Breeze will point you in the right direction.

This is a game-changer for marketers and RevOps pros who are constantly searching for solutions but don't always know the exact app name or category. It cuts down on research time and helps you find the right fit faster, potentially uncovering powerful e-commerce integrations you might have missed.

Self-Service Client Secret Rotation for Enhanced Security

Security is paramount, especially when dealing with customer data and payment information in e-commerce. Previously, rotating an app's client secret (a crucial security measure) required a support ticket. Now, app owners can do this directly from the Developer Platform UI with a new "Rotate" button.

Why this matters: If an app's client secret is ever compromised, you can now take immediate action to invalidate the old secret and generate a new one. This self-service capability significantly enhances your security posture and allows for swift responses to potential incidents, protecting your valuable e-commerce data and customer trust.

New Workflow Action: Automate Marketing Event Participant Status

Finally, a direct win for marketers and event organizers! HubSpot has introduced a new workflow action that lets you automatically update a contact's participant state for manually created Marketing Events. You can set contacts as 'Registered', 'Attended', or 'Canceled'.

E-commerce application: If your e-commerce brand runs webinars, virtual product launches, or in-person events (even if they're not directly tied to a specific ticket system), this streamlines your follow-up. You can trigger different nurture sequences based on participation, ensuring your leads get the right message at the right time. For example, those who attended a product demo webinar could receive a discount code, while those who registered but didn't attend get a recording and a different offer.

ESHOPMAN Team Comment

We think this developer rollup is a powerful indicator of HubSpot's commitment to a more robust, secure, and developer-friendly platform. The CRM card migration is a critical task for anyone with custom e-commerce data in HubSpot, and the new tool makes it far less painful. The Custom Channels API enhancements are particularly exciting for creating truly personalized and trackable customer journeys, which is essential for modern e-commerce. These updates reinforce that HubSpot is continuously evolving as a strong foundation for sophisticated e-commerce and RevOps strategies.

So, there you have it! While these announcements might seem geared towards developers, their implications for your e-commerce business and RevOps efficiency are huge. Stay proactive, work with your tech teams, and keep leveraging HubSpot's evolving capabilities to drive growth and deliver exceptional customer experiences.
