Getting 401 error when webhook confirmation handshake being sent to a flow - allow anonymous access?

(0) ShareShare

Posted on by

Hi-
I’m trying to use a flow to establish a webhook with Asana by following this guide.  The flow is using a trigger "When a HTTP request is received"

 

The steps for the flow are:

  • Trigger a webhook creation from Postman to Asana using an HTTP POST request
  • Asana sends a confirmation handshake to my flow using the HTTP POST URL
  • See screenshot below.

Unfortunately, I keep receiving a 401 error from Asana since I think my flow is requiring Asana provide some form of  authentication.  How do I allow anonymous access to the flow?  I will turn the flow off once I've established the webhook, so it will only be exposed for a minute or so.

 

Thanks.
