HubSpot CRM Card Iframes: Sizing, Data Passing & E-commerce Integrations

At ESHOPMAN, we're dedicated to empowering online shop makers and e-commerce businesses to thrive within the HubSpot ecosystem. Our mission is to provide a built-in storefront and robust e-commerce capabilities that seamlessly integrate with your HubSpot CRM, Sales Hub, and Service Hub. A crucial aspect of building a truly unified RevOps strategy is leveraging HubSpot's extensibility features, such as custom CRM cards. These powerful tools allow you to bring external data and actions directly into your HubSpot records, making your sales and service teams incredibly efficient.

Recently, a fascinating discussion in the HubSpot Community forum highlighted some common challenges developers face when working with these custom cards, specifically regarding iframe primary actions. Understanding these nuances is key to building a flawless, integrated experience for your online store, whether you're managing orders, tracking shipments, or processing refunds.

The Power of Custom CRM Cards for E-commerce

Custom CRM cards are game-changers for e-commerce businesses. Imagine having real-time order details, customer lifetime value, or even the ability to initiate a refund or re-order directly from a contact or deal record in HubSpot. This is precisely what custom CRM cards enable. They act as windows into external systems, embedding crucial information and actions right where your team needs them most.

The 'legacy card converter' mentioned in the community thread refers to a tool designed to help developers create or migrate UI extensions that display custom information or actions within HubSpot records. While HubSpot's UI extension capabilities have evolved, understanding the underlying principles of how these cards interact with iframes remains vital for any developer or store operator looking to deeply integrate their e-commerce platform with HubSpot.

The Iframe Primary Action Conundrum: Sizing and Data Flow

The community discussion began with an original poster encountering issues with a custom CRM card utilizing an iframe as its primary action. The card itself rendered correctly, but the iframe within it was misbehaving. Specifically, it displayed at an incorrect size (much smaller than intended) and, more critically, failed to pass the specified associatedObjectProperties as query parameters to the iframe's URI.

Initially, a community member suggested that empty uri and label fields might be the culprit. However, the original poster quickly clarified that these fields were indeed populated, providing a more complete code snippet:

let resp
  results: [
    {
      title: 'Convert To New Currency',
      objectId: process.env.CR8_CARD_ID,
      currency: `${currency.name} (${currency.symbol}) ${currency.sign}`,
      amount: currency.sign + parseFloat(amount).toFixed(2)
    }
  ],
  primaryAction: {
    type: 'IFRAME',
    uri: `${process.env.BASE_URL}/currencyr8/crmcard/iframe?currency=${currency.symbol}&portalId=${portalID}`,
    label: 'Convert Currency',
    associatedObjectProperties: [
      'amount',
      'deal_currency_code',
      'hs_object_id'
    ],
    width: '600',
    height: '400'
  }
};

Even with explicit width: '600' and height: '400' values, the iframe was rendering at a much smaller 300x150 pixels within a full-width popup. This highlighted a common misunderstanding of how these dimensions are interpreted by HubSpot's UI.

Decoding Iframe Sizing and Data Transmission

Let's break down the two core issues and provide actionable insights for ESHOPMAN users and developers:

1. Iframe Sizing in HubSpot CRM Card Primary Actions

When you define width and height within the primaryAction object for an IFRAME type, these dimensions typically control the size of the modal or popup window that contains your iframe, not the iframe element itself. Within that modal, the iframe is often designed to take up 100% of the available width and height of its parent container. The original poster's observation of a 300x150 iframe within a larger popup suggests that HubSpot's UI might have a default minimum size for the iframe container or that the specified 600x400 was indeed for the modal that then contained a smaller iframe due to other CSS rules or responsive design within HubSpot's framework.

Actionable Insight: To control the visual dimensions of your iframe's content, you should primarily manage the responsiveness and layout within the HTML and CSS of the page loaded inside the iframe. Ensure your iframe content is designed to be fully responsive and adapts well to various container sizes. While the width and height properties in the primaryAction are important for the modal, don't rely solely on them to dictate the internal rendering of your embedded application.

2. Passing `associatedObjectProperties` to Iframes

The associatedObjectProperties array is designed to automatically append the values of specified HubSpot object properties as query parameters to your iframe's uri. For example, if hs_object_id is '123' and amount is '500.00', your URI might become something like your-iframe-url?currency=USD&portalId=123456&hs_object_id=123&amount=500.00.

The original poster's issue of these properties not being sent is critical. Here's why this might happen and how to troubleshoot:

Property Existence: Ensure that the associatedObjectProperties you list (e.g., amount, deal_currency_code, hs_object_id) actually exist and have values on the HubSpot object (e.g., a Deal or Contact) from which the CRM card is being loaded. If a property is empty or doesn't exist, it won't be passed.
Correct Object Type: Verify that the CRM card is associated with the correct object type (e.g., Deal, Contact, Company) that possesses these properties.
URI Inspection: The most straightforward debugging step is to inspect the network requests in your browser's developer tools when the iframe primary action is triggered. Look at the actual URL loaded by the iframe to see if the query parameters are present.
Encoding: While HubSpot typically handles URI encoding, ensure that any values you're passing directly in your uri (like currency=${currency.symbol}) are properly encoded if they contain special characters.

Actionable Insight: Always validate the presence and values of your associatedObjectProperties on the target HubSpot object. Use browser developer tools to confirm the final URI loaded by the iframe. If properties are still missing, consider passing them via a different mechanism, such as HubSpot's UI Extension SDK, which offers more robust data exchange capabilities between the parent HubSpot window and your iframe.
