Azure OAuth2 Client Credentials Grant Flow

See more OAuth2 Examples

Demonstrates how to get an OAuth2 access token for an Azure Registered App using the Client Credentials Grant Flow.

Note: Your Azure app must be registered as a single-tenant app to use client credentials.

Ruby

require 'chilkat'

success = false

#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

http = Chilkat::CkHttp.new()

req = Chilkat::CkHttpRequest.new()
req.AddParam("client_secret","CLIENT_SECRET")
req.AddParam("client_id","CLIENT_ID")

#  See Understanding Scopes in Azure OAuth2 Client Credentials Flow
req.AddParam("scope","https://graph.microsoft.com/.default")

req.AddParam("grant_type","client_credentials")

#  Note: Your Azure app must be registered as a single-tenant app to use client credentials.
#  Use your own tenant ID, for example 4d8fdd66-66d1-43b0-ae5c-e31b4b7de5cd
url = "https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token"

req.put_HttpVerb("POST")
req.put_ContentType("application/x-www-form-urlencoded")

resp = Chilkat::CkHttpResponse.new()
success = http.HttpReq(url,req,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

statusCode = resp.get_StatusCode()
print "Response status code = " + statusCode.to_s() + "\n";

json = Chilkat::CkJsonObject.new()
json.Load(resp.bodyStr())

json.put_EmitCompact(false)
print json.emit() + "\n";

#  Sample successful output:

#  {
#    "token_type": "Bearer",
#    "expires_in": 3599,
#    "ext_expires_in": 3599,
#    "access_token": "eyJ0eX...K0jOERg"
#  }

if (statusCode == 200)
    json.WriteFile("qa_data/tokens/azureClientCredentialsToken.json")
    print "Success." + "\n";
else
    print "Failed." + "\n";
