HubSpot API v4 and hs_object_source_detail

HubSpot's APIs are powerful tools, but sometimes you run into unexpected behavior. A recent HubSpot Community thread highlighted an issue with the hs_object_source_detail_3 property when using the Single Send API v4. Let's break down the problem and explore potential solutions.

The Issue: Read-Only Error with hs_object_source_detail_3

The original poster encountered an error when trying to set the hs_object_source_detail_3 property during object creation using the /marketing/v4/email/single-send endpoint. The error message indicated that the property was read-only, even though it worked fine with direct object creation and the v3 endpoint /marketing/v3/transactional/single-email/send/.

The core question was whether this behavior in the v4 API was a bug or an intentional design choice, impacting migration plans.

Understanding the Property and API Behavior

hs_object_source_detail_3 is a HubSpot property that provides further detail about the source of a contact or company. It's often used to track how an object was created or updated. The expectation is that you can set this property on creation but not necessarily update it directly afterward.

The respondent in the thread shared links to HubSpot's knowledge base and developer documentation, which provide general information about default contact properties and the Single Send API v4. While these resources don't directly address the read-only issue, they offer context about how the API and properties are intended to function.

Possible Causes and Workarounds

Here's a breakdown of potential reasons for this behavior and how to handle it:

API Design: It's possible that the v4 API intentionally restricts write access to hs_object_source_detail_3 for single sends. This could be due to changes in how HubSpot tracks the source of these interactions.
Timing: Ensure you're setting the property during the initial object creation process. Trying to modify it afterward might trigger the read-only error.
Alternative Properties: Consider using a custom property to store the information you intended to put in hs_object_source_detail_3. While it's not ideal, this allows you to track the source detail without running into the API restriction.
Review API Documentation: Double-check the HubSpot API documentation for the Single Send v4 endpoint for any specific notes on writable properties during creation.

General Tips for HubSpot API Integrations

When working with HubSpot's APIs, keep these best practices in mind:

Stay Updated: HubSpot's APIs evolve. Regularly review the changelog and documentation for any updates that might affect your integrations.
Error Handling: Implement robust error handling in your code to gracefully manage unexpected API responses.
Testing: Thoroughly test your integrations in a development environment before deploying them to production.

ESHOPMAN Team Comment

This issue highlights the importance of carefully testing API migrations. While HubSpot provides extensive documentation, unexpected changes in behavior can still occur. Using custom properties can be a good workaround when encountering limitations with default properties like hs_object_source_detail_3. For e-commerce businesses using HubSpot, ensuring accurate source tracking is crucial for attribution and reporting.
