How to match contact property to use for matching in OneSignal Integration settings?

How can I specified the correct contact property to use for matching in OneSignal Integration settings?
In sending OneSignal notification, After selecting an App name. I can select method for matching HubSpot Contact to OneSignal device. So I can select “Match by OneSignal external_user_id”. I have existing property created in my contact property to match the external user id. However, I cannot find any help or guide for matching my created property to external_user_id.
Please help. Thank you very much!

Hey, @JMadid :waving_hand: Thank you for your question.

While I don’t have this specific integration in my portal to test with, I do have a few questions to get us started on the troubleshooting path.

From the guide:

  • In your HubSpot account, click the Marketplace icon
  • Under Manage, select Connected apps
  • Click OneSignal
  • Click Contact Matching
  • From the dropdown menu, select the HubSpot contact property you want to use for matching with the OneSignal external_user_id property

Can you get through those steps?
