Zoom API - Create JWT to Authenticate API Requests

See more Zoom Examples

var success = false;

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

// Use your API key and secret here...
var apiKey = "o9rw6Gq0RnqlkfaSqtCMOA";
var apiSecret = "UslmE23Kjh7at9z3If1xAHEyLmPDNxvxQrjR";

// Create a JWT to authenticate Zoom API requests.
var jwt = new CkJwt();

var jose = new CkJsonObject();
success = jose.UpdateString("alg","HS256");
success = jose.UpdateString("typ","JWT");

// Build claims to look like this:
// {"aud":null,"iss":"o9rw6Gq0RnqlkfaSqtCMOA","exp":1627651762,"iat":1627646363}
var claims = new CkJsonObject();
success = claims.UpdateString("iss",apiKey);
success = claims.UpdateNull("aud");

// Set the timestamp of when the JWT was created to now.
var curDateTime = jwt.GenNumericDate(0);
success = claims.AddIntAt(-1,"iat",curDateTime);

// Set the timestamp defining an expiration time (end time) for the token
// to be now + 1 month(3600 * 24 * 30 seconds)
var oneMonth = 3600 * 24 * 30;
success = claims.AddIntAt(-1,"exp",curDateTime+oneMonth);

// Produce the smallest possible JWT:
jwt.AutoCompact = true;

var strJwt = jwt.CreateJwt(jose.Emit(),claims.Emit(),apiSecret);

console.log(strJwt);

// Let's test the JWT to by sending the following request:

// curl --request GET \
//   --url 'https://api.zoom.us/v2/users?status=active&page_size=30&page_number=1' \
//   --header 'authorization: Bearer { your_token }' \
//   --header 'content-type: application/json

var http = new CkHttp();

// Implements the following CURL command:

// curl --request GET \
//   --url 'https://api.zoom.us/v2/users?status=active&page_size=30&page_number=1' \
//   --header 'authorization: Bearer { your_token }' \
//   --header 'content-type: application/json

// Use the following online tool to generate HTTP code from a CURL command
// Convert a cURL Command to HTTP Source Code

http.SetRequestHeader("content-type","application/json");
// Adds the "Authorization: Bearer { your_token }" header.
http.AuthToken = strJwt;

var sbResponseBody = new CkStringBuilder();
success = http.QuickGetSb("https://api.zoom.us/v2/users?status=active&page_size=30&page_number=1",sbResponseBody);
if (success == false) {
    console.log(http.LastErrorText);
    return;
}

var jResp = new CkJsonObject();
jResp.LoadSb(sbResponseBody);
jResp.EmitCompact = false;

console.log("Response Body:");
console.log(jResp.Emit());

var respStatusCode = http.LastStatus;
console.log("Response Status Code = " + respStatusCode);
if (respStatusCode >= 400) {
    console.log("Response Header:");
    console.log(http.LastHeader);
    console.log("Failed.");
    return;
}
