Test Salesforce OAuth2 Access Token

See more Salesforce Examples

Demonstrates how to make a simple Salesforce REST API call to test a previously obtained access token. Rust

// This example does the following:

// curl -X GET https://yourInstance.salesforce.com/services/oauth2/userinfo \
//      -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

let http = chilkat::Http::new();

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

// This example assumes the OAuth2 access token was previously fetched 
// and saved to a file.  See Get SalesForce OAuth2 Access Token via Authorization Flow

let json = chilkat::JsonObject::new();
if json.load_file("qa_data/tokens/_salesforce.json").is_err() {
    println!("Failed to load OAuth2 access token.");
    return;
}

// Here's an example of the JSON:

// {
//   "access_token": "00D41000....uLZBpT6",
//   "refresh_token": "5Aep....25xdGgkrV",
//   "signature": "cjTbSc5DvcKpaMoRTzuQTJLb1tcMw8LEO01flq4aMD4=",
//   "scope": "refresh_token id",
//   "instance_url": "https://d41000000f8a0eak-dev-ed.my.salesforce.com",
//   "id": "https://login.salesforce.com/id/00D41000000F8A0EAK/005410000....xAAE",
//   "token_type": "Bearer",
//   "issued_at": "1738348388166"
// }

// Adds the "Authorization: Bearer YOUR_ACCESS_TOKEN" header.
http.set_auth_token(&json.string_of("access_token").unwrap_or_default());

// We want to build the following URL:  https://<instance_id>.salesforce.com/services/oauth2/userinfo
let sb_url = chilkat::StringBuilder::new();
let _ = sb_url.append(&json.string_of("instance_url").unwrap_or_default());
let _ = sb_url.append("/services/oauth2/userinfo");

let sb_response_body = chilkat::StringBuilder::new();
if http.quick_get_sb(&sb_url.get_as_string().unwrap_or_default(), &sb_response_body).is_err() {
    println!("{}", http.last_error_text());
    return;
}

println!("Response status code = {}", http.last_status());

let json_response = chilkat::JsonObject::new();
let _ = json_response.load_sb(&sb_response_body);
json_response.set_emit_compact(false);
println!("{}", json_response.emit().unwrap_or_default());

// The expected JSON response is something like this:

// {
//   "sub": "005xxxxxxxxxxxx",
//   "name": "John Doe",
//   "preferred_username": "johndoe@example.com",
//   "email": "johndoe@example.com",
//   "profile": "https://na85.salesforce.com/005xxxxxxxxxxxx"
// ...
// ...
// }
