Changelog

Regenerated the Rust SDK to incorporate latest API documentation improvements. See July 28, 2026 for more information.

Added OAuth2 client-credentials support. Set client_id/client_secret on ClientConfig instead of api_key and the SDK handles the token exchange and refresh automatically:

1
let config = ClientConfig {
2
    client_id: Some(CLIENT_ID.to_string()),
3
    client_secret: Some(CLIENT_SECRET.to_string()),
4
    base_url: Environment::Sandbox.url().to_string(),
5
    ..Default::default()
6
};

As part of an ongoing effort to improve the consistency and usability of our SDKs, we’ve updated the SDK generation process. This update introduces breaking changes to the SDK. All breaking changes affect only method signatures and namespacing, not core record types or properties. SDK initialization, configuration, business logic, and workflows remain unchanged. For more information on precise method signatures and example usage, please see the SDK reference on GitHub.
