Invoke Web Job with credentials on HTTP Post Action in Logic App Fails with 401 Unauthorized

Question

I'm trying to invoke a triggered web job in Azure from a Logic App. I am using the HTTP action posting the following URL:

Method:
POST

Uri:
https://$slicetime:[e-mail]/api/triggeredwebjobs/FullSync/run?arguments%3D-x+-n

No Headers, No Body.

The Outputs are

• Status code
  401
• Headers
  { "Date": "Mon, 31 Oct 2016 06:07:31 GMT", "Server": "Microsoft-IIS/8.0", "WWW-Authenticate": "Basic realm=\"site\"", "Content-Length": "1293", "Content-Type": "text/html" }
• Body
  ...<title>401 - Unauthorized: Access is denied due to invalid credentials.</title> <
• ...<h1>Server Error</h1>
• ...<h2>401 - Unauthorized: Access is denied due to invalid credentials.</h2>
• ... <h3>You do not have permission to view this directory or page using the credentials that you supplied.</h3>

The HTTP post works fine with curl and Postman. Any ideas?

Thanks

Hi Barry,

Seems like cURL uses the syntax

http://myusername:[e-mail]

Based on your URL, you can you try the following on the HTTP action:

URL: https://slicetime.scm.azurewebsites.net/api/triggeredwebjobs/FullSync/run?arguments%3D-x+-n

Method: POST

Headers:

{
“Authorization”:”Basic @base64(‘$slicetime:AAMYKEYAA’)”
}

This might do the trick.

I hope this helps, Wagner.

Answer 2

Thank you Wagner,

I wasn't able to get the @base64 function to work. Same error message, but you got me pointed in the right direction. I manually encoded by userid & password (with the $) and then just used that in the header. I also in my attempts ended up with a content type. This solution works.

{
  "Authorization": "Basic mybase64useridandkeyendingwith=",
  "Content-Type": "application/json"
}

Great to know mate.

Here is how I created the Authorization on my case:

{
   "Authorization": "Basic @{base64(parameters('$mycredentials'))}",
    "Content-Type": "application/json"
}

Then my $mycredentials parameter looks like this:

"parameters": {
            "$connections": {
                "defaultValue": {},
                "type": "Object"
            },
            "$mycredentials": {
                "defaultValue": "username:password",
                "type": "String"
            }
}

I hope this helps, Wagner.
