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

// Insert your Bearer token here:
NSString *accessToken = @"VOICEBASE_TOKEN";

CkoHttp *http = [[CkoHttp alloc] init];

// Add the access (bearer) token to the request, which is a header
// having the following format:
// Authorization: Bearer <userAccessToken>
CkoStringBuilder *sbAuth = [[CkoStringBuilder alloc] init];
[sbAuth Append: @"Bearer "];
[sbAuth Append: accessToken];
[http SetRequestHeader: @"Authorization" value: [sbAuth GetAsString]];

NSString *strJson = [http QuickGetStr: @"https://apis.voicebase.com/v2-beta/media"];
if (http.LastMethodSuccess != YES) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

// The response should be JSON, even if an error.
CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json Load: strJson];
json.EmitCompact = NO;

NSLog(@"%@%d",@"Response status code = ",[http.LastStatus intValue]);

if ([http.LastStatus intValue] != 200) {
    NSLog(@"%@",[json Emit]);
    NSLog(@"%@",@"Failed");
    return;
}

// See the sample JSON response below..

// Iterate over the JSON like this:
CkoDateTime *dt = [[CkoDateTime alloc] init];
int mediaCount = [[json SizeOfArray: @"media"] intValue];
int i = 0;
while (i < mediaCount) {
    json.I = [NSNumber numberWithInt: i];

    NSString *dateCreated = [json StringOf: @"media[i].dateCreated"];
    [dt SetFromTimestamp: dateCreated];

    i = i + 1;
}
