Calling Rest Api From Plugin

Posted on by Community Member

I have created a plugin which get activated when any new connection created.

And in plugin i am calling a REST api to store data in our OLD system.

But when i am calling  like below

bytes = Encoding.UTF8.GetBytes(PayLoad);

  1. using (var client = new WebClient())
  2. {
  4. client.Headers[HttpRequestHeader.Accept] = "application/json";
  5. client.Headers[HttpRequestHeader.ContentType] = "application/json";
  6. client.Encoding = Encoding.UTF8;
  7. var response = client.UploadData(RestUrl, "PUT", bytes);
  9. return Encoding.UTF8.GetString(response);
  10. }

But its not running and when i am debugging it comes on line 7 and when i hit F10 it getting stop and my Plugin Registration Tool also get crashed.

If it don't get crash i can get the exception but due to that i am unable to catch the cause.

Thanks,

Rahul tiwari

    Actually, if you log to the tracingservice the plugin actually carries on.  Its just the plugin registration tool does not seem to like web service calls like this.  I got around the issue by just being very verbose with the tracing service.

    What is the authentication mechanism for the service?

    Please note :

    Sandboxed plug-ins and custom workflow activities can access the network through the HTTP and HTTPS protocols. This capability provides support for accessing popular web resources like social sites, news feeds, web services, and more. The following web access restrictions apply to this sandbox capability.

    • Only the HTTP and HTTPS protocols are allowed.
    • Access to localhost (loopback) is not permitted.
    • IP addresses cannot be used. You must use a named web address that requires DNS name resolution.
    • Anonymous authentication is supported and recommended. There is no provision for prompting the logged on user for credentials or saving those credentials.
