API Not Triggering on Contact Creation?

[sethg]

I am trying to set up a call to notfiy an external app when contact is created in Hubspot. I built a webhook subscription with the Object and Event of Contact Creation. When I test the subscription it works. However, when a real contact is created in Hubspot it doesn't trigger the API. Am I missing a step to get it live and working?

Hi @sethg , your application that you created the webhook subscription in must be installed in the account you're looking to get notifications for. Have you installed your application by going through the OAuth flow yet? https://developers.hubspot.com/docs/methods/oauth2/oauth2-overview
