Hi,  
Building my own app in Hubspot to connect with a custum connector in Power Automate, using Oauth. Works fine!

Now I’m registering for a webhook from PA to Hubspot, setting up goes fine. Webhook is triggered, but then getting a error:

**Header** : “x-hubspot-auth-failure”: “401 Unauthorized”,

**Body** : {  
“status”: “error”,  
“message”: “Authentication credentials not found. This API supports both API Key and OAuth 2.0 authentication and you can find more details at [Accounts Dashboard | HubSpot](https://developers.hubspot.com/docs/methods/auth/oauth-overview)”,  
“correlationId”: “xxx”,  
“category”: “INVALID\_AUTHENTICATION”  
}  
Is there any special permission/authorization required for the usage of the webhooks?

Hi, @RDoorn 👋 Thanks for reaching out. Can you post an example of what your request looks like? It’s not possible to give a definitive answer, but in other posts with the same error, a common culprit was sending the authorization in the URL.

Best,

Jaycee

Hi [@Jaycee\_Lewis](https://community.hubspot.com/t5/user/viewprofilepage/user-id/127074) , thanks. This is a sample
