Salesforce to BIt.ly API Integration using HTTP CallOut

 1. Using in site URL

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

@RestResource(urlMapping='/ProcessBitlyAPIService/*')

Global with sharing class BitlyWebService {

    @HttpPost

    global static void AcuityWebService1123() {

        string username = '**************'; //Bitly username

        String password = '**************'; //Bitly password

        Blob headerValue = Blob.valueOf(username + ':' + password);

        String authorizationHeader = 'BASIC ' +EncodingUtil.base64encode(headerValue);

        

        //String authorizationHeader = 'Basic'+base64encode(username + ":" + password);

        

       

        //BitlyCalloutService.doGet12(authorizationHeader);

}

}
