How does it work?

This extension uses the callExtension method provided by the CometChat Pro SDK.
You can call the extension as follows:

                        'POST', 'v1/shorten', 
                        {text: "Your message with URL"})
  .then(response => {
    // minifiedText in response
.catch(error => {
    // Error occured
String URL = "/v1/shorten";
JSONObject body=new JSONObject();

body.put("text", "Your message with URL");

CometChat.callExtension("url-shortener-bitly", "POST", URL, body,
new CometChat.CallbackListener < JSONObject > () {
    public void onSuccess(JSONObject jsonObject) {
        // minifiedText from the extension
    public void onError(CometChatException e) {
        // Some error occured
CometChat.callExtension(slug: "url-shortener-bitly", type: .post, endPoint: "/v1/shorten", body: ["text": "Your message with URL"], onSuccess: { (response) in
        // minifiedText from the extension
      }) { (error) in
        // Some error occured
