Hello all,  
I’m trying to understand the differences between some call properties: hs\_object\_source, hs\_object\_source\_label,

hs\_engagement\_source, and

hs\_call\_source.

In addition, I’m trying to understand what the different value options are for each one.

For example for hs\_object\_source\_label I see COMMUNICATOR,

INTERNAL\_PROCESSING, and

INTEGRATION. What do those values mean?

Thank you in advance,

MGoldstone

Hi @MGoldstone

The Call Objects API in HubSpot includes several properties that provide insight into the origin and context of calls.

The hs\_object\_source property identifies the initial source of the contact associated with the call, such as organic search, paid search, or email marketing.

The hs\_object\_source\_label provides a human-readable label for this source, making it easier to understand.

The hs\_engagement\_source property, on the other hand, specifies the specific interaction that triggered the call, like a web form submission, meeting, or email interaction.

Ultimately, the hs\_call\_source property, which may be deprecated in newer API versions, potentially captured the source of the call itself, such as a phone number dialed or an inbound call from a website.

In summary, these properties help distinguish between the initial contact source, the interaction leading to the call, and the call’s origin, providing valuable context for calls in HubSpot.

**Hope this helps - Happy to help further!!**
