Hello,  
I wanted to add authentication on a webhook that is triggered from a workflow, however, it says I should add **Authentication Type,** not **App Id**. The documentation doesn’t say anything about **Authentication Type,** even if I add the App ID which is in the URL, it says: **Action is invalid: INVALID\_APP\_ID.  
 [How to Trigger Webhooks in HubSpot Contact-Based Workflows](https://knowledge.hubspot.com/workflows/how-do-i-use-webhooks-with-hubspot-workflows)**  
That documentation says you should insert **App Id** not, not **Authentication Type.**  
Any ideas on how I can add authentication here?

@Socke

I am asking the internal team about this. I will get back to you when I have an answer!

The [docs](https://knowledge.hubspot.com/workflows/how-do-i-use-webhooks-with-hubspot-workflows) says:

To verify that the requests received at your URL are from HubSpot:

- Own a developer account. If you don’t have one, [sign up for a developer account](https://app.hubspot.com/signup-v2/developers/step/join-hubspot).
- Own an app. If you don’t have an app, learn how to [create an app](https://developers.hubspot.com/docs/faq/how-do-i-create-an-app-in-hubspot).
- [Check the hash value of the signature](https://developers.hubspot.com/docs/methods/crm-extensions/crm-extensions-overview#request-signatures).

My apologies, I forgot to create an app and a developers account. I took the **App Id** from the developers account and now the signature works!  
Thanks @dennisedson for responding.
