Not able to get web hook signature from redirect URL headers,

Now web hook signature is not able get from redirect URL headers

Could you elaborate what you mean by this? Is the registered webhook handler issuing a redirect to the Community?

Hi Ben,

Below is code snippet as per documentation(https://community.telligent.com/community/12/a/developer-training/c/webhooks ) of webhook.

-------------------------------------------------------------------------

string senderUrl = HttpContext.Request.Headers["X-Telligent-Webhook-Sender"];
string hashSignature = HttpContext.Request.Headers["X-Telligent-Webhook-Signature"];

string rawPostData;
using (var reader = new System.IO.StreamReader(HttpContext.Request.InputStream))
{
rawPostData = reader.ReadToEnd();
}

// Validate the posted data's authenticity
string calculatedSignature = CalculateSignature(rawPostData, SECRET_KEY);
if (!hashSignature.Equals(calculatedSignature))

----------------------------------------------------------------------------

In the last line, we are trying to compare hashSignature which is provided by Telligent framework to the calculatedSignature generated by rawPostData &  SECRET_KEY.

Once this condition matches we proceed further, but in current scenario we are unable to receive any value from HttpContext.Request.Headers["X-Telligent-Webhook-Signature"] 

So, please guide me if i am missing any configuration to receive value successfully.

Thanks

If you are attempting to redirect the response on your side you shouldn't.  There should not be an expectation that when you do a redirect that headers are redirected as well(they generally are not).

Our only query is we are not getting string value of  hashSignature = HttpContext.Request.Headers["X-Telligent-Webhook-Signature"];

do we need to do some kind of backend configuration for this?

What is you webhook handler doing?  Are you trying to read the headers in the page/endpoint community is calling or are you attempting to redirect the request elsewhere then read the headers?
