New business_summary field on PaypointData

// Before
client

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:

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

Changed the VendorQueryRecord.additional_data type from HashMap<String, HashMap<String, serde_json::Value>> to HashMap<String, String> to match the API.

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.

Fixed an issue where the Rust SDK wasn’t properly deserializing the extra_data field in certain API response models.

Regenerated the Rust SDK to incorporate latest API documentation improvements. See May 11, 2026 for more information.

Fixed a bug that caused the CustomerSummary object to be deserialized incorrectly in customer records. Fixed a bug that caused the InvoiceData object to be deserialized incorrectly in transaction records. Regenerated the Rust SDK to incorporate latest API definition updates.
