C# SDK changelog

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

Added OAuth2 client-credentials support. Pass clientId/clientSecret and the SDK handles the token exchange and refresh automatically:

1
var client = new PayabliApiClient(
2
    clientId: "...",
3
    clientSecret: "...",
4
    clientOptions: new ClientOptions { BaseUrl = PayabliApiEnvironment.Sandbox }
5
);

See the C# SDK guide and Authentication to compare both methods.

Changed the VendorQueryRecord.AdditionalData type from Dictionary<string, Dictionary<string, object?>>? to Dictionary<string, string>? to match the API.

Increased support for additional date formats on bill dueDate and invoiceDate fields to prevent crashes when deserializing a non-ISO date string returned by MoneyOut.PayoutDetails in the Bills array.

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.
