Retrieve Sequence Endpoint Not Returning emailPattern Attribute

Develop, Build & Integrate APIs & Integrations
1

Hi guys, when using the Retrieve Sequence endpoint the documentation specifies that an emailPattern attribute should be returned if the actionType = EMAIL. However in my testing this is not the case. Am I doing something wrong?

curl -i  --request GET \
  --url https://api.hubapi.com/automation/sequences/2026-09/serviceaccounts/sequences/310649634 \
  --header 'Authorization: Bearer TOKEN'

Hi @MJohnson59, I hope that you are well!

Thanks for asking the HubSpot Community and for sharing the API link, that’s useful!

According to the documented response schema for Retrieve a sequence, the emailPattern property is defined as an object (type: object) but isn’t marked as required (required: true).

This means that emailPattern is an optional field and will only be included in the response when available, rather than being guaranteed for every step with an EMAIL action type.

I’d love to hear from our Top Experts: Hi @Anton, @evaldas and @zach_threadint are you experiencing the same with this endpoint, please? Do you have suggestions to help @MJohnson59?

If you see the same, I’ll investigate interanlly.

Thanks so much and wishing you a great day!
