For details regarding making API calls with the VideoSDK, refer to this section in the documentation - Make API requests

If you are using the UI Toolkit, I believe you will also need the Web VideoSDK as well.

Let me know if this helps :slight_smile:

Hey @kellyjandrews. I have referred the shared link and it is giving me an error.

StatusCode: Unauthorized
{“code”:124,“message”:“Invalid access token.”}

Can you please look into this on some priority.

Thanks

Invalid Access Token can represent a couple of different scenarios - but most typically is due to using the incorrect Key/Secret.

In your VideoSDK developer account, be sure you are using the API key/secret to call the API, and not the SDK key/secret.

Hey @kellyjandrews ,
I’m sure on using API and API secret, so what will be the other possible reason.
Also I have used JWT token which is available in Video SDK APP, please refer below image

Code to generate the token is as below, using .Net Core C#.

using System.IdentityModel.Tokens.Jwt;

public string GetVideoSDKAPIToken(string apiKey, string apiSecret, int accessTokenValidityInMinutes = 120, int tokenValidityInMinutes = -1)
        {
            DateTime now = DateTime.UtcNow;

            if (tokenValidityInMinutes <= 0)
            {
                tokenValidityInMinutes = accessTokenValidityInMinutes;
            }

            int tsNow = (int)(now - new DateTime(1970, 1, 1)).TotalSeconds;
            int tsAccessExp = (int)(now.AddMinutes(accessTokenValidityInMinutes) - new DateTime(1970, 1, 1)).TotalSeconds;
            int tsTokenExp = (int)(now.AddMinutes(tokenValidityInMinutes) - new DateTime(1970, 1, 1)).TotalSeconds;

            return GenrateVideoSDKAPIToken(apiSecret, new JwtPayload
                {
                    { "iss", apiKey },
                    { "exp", tsAccessExp },
                    { "iat", tsNow }                                        
            });
        }
		
public static string GenrateVideoSDKAPIToken(string apiSecret, JwtPayload payload)
        {
            // Create Security key using private key above:
            // note that latest version of JWT using Microsoft namespace instead of System
            var securityKey = new Microsoft.IdentityModel.Tokens.SymmetricSecurityKey(Encoding.UTF8.GetBytes(apiSecret));

            // Also note that securityKey length should be >256b
            // so you have to make sure that your private key has a proper length
            var credentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);

            // Finally create a Token
            var header = new JwtHeader(credentials);
            var secToken = new JwtSecurityToken(header, payload);
            var handler = new JwtSecurityTokenHandler();

            // Token to String so you can use it in your client
            return handler.WriteToken(secToken);
        }

Code to call a API,

var client = new RestClient(_zoomConfiguration.Zoom_Base_URL + "/videosdk/sessions/" + sessionid + "/events");

                var request = new RestRequest(Method.PATCH);
                request.AddHeader("content-type", "application/json");
                request.AddHeader("authorization",  token);
                request.AddParameter("application/json", json, ParameterType.RequestBody);

                IRestResponse response = await client.ExecuteAsync(request);
                responseObj = JsonConvert.DeserializeObject<CallOutDTO>(response.Content);
