Refinitiv World-Check One - Get Top Level Groups

See more Refinitiv Examples

Sends a signed GET request to get the top level groups.

Note: This example requires Chilkat v9.5.0.89 or later.

Rust

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

let json = chilkat::JsonObject::new();

// Create the following JSON:
// 
// {
//   "keyId": "aaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
//   "hmacKey": "xxxxzI3vi58xxxCBxxx1+P/d8tGxx7KuLqN/KMPNxxxxekhj8/bx83+1YQSUxxxxYyv939ceY06GvhYRKmxxxx==",
//   "algorithm": "hmac-sha256",
//   "headers": [
//     "(request-target)",
//     "host",
//     "date"
//   ]
// }

// Substitute your actual API key and API secret in place of "api-key" and "api-secret"
let _ = json.update_string("keyId", "api-key");
let _ = json.update_string("hmacKey", "api-secret");
let _ = json.update_string("algorithm", "hmac-sha256");
// Indicate the names of the headers to be included in the signature.
// "(request-target)" is not actually a header name, but is a special name for HTTP signatures.
// Copy the following three lines of code exactly as-is.  
// Do not replace "host", "date", or "(request-target)" with values.
let _ = json.update_string("headers[0]", "(request-target)");

// Setting the AuthSignature property causes the following header to be computed and added:
// Authorization: Signature keyId="...", algorithm="hmac-sha256", headers="(request-target) host date", signature="..."
http.set_auth_signature(&json.emit().unwrap_or_default());

http.set_request_header("Cache-Control", "no-cache");

// Chilkat will auto-add the Date header because it's needed by the HTTP Signature.

let Ok(response_json) = http.quick_get_str("https://api-worldcheck.refinitiv.com/v2/groups") else {
    println!("{}", http.last_error_text());
    return;
};

println!("{}", response_json);
println!("----");
// A 200 status code indicates success.
println!("Status code = {}", http.last_status());

// Successful JSON looks like this:
// [

//   "name": "Company Name",
//   "parentId": null,
//   "hasChildren": false,
//   "status": "ACTIVE",
