New BusinessSummary field on PaypointData

PaypointData now includes BusinessSummary, a business description from boarding. See August 28, 2026 for more information.

Added OAuth2 client-credentials support via option.WithClientID/option.WithClientSecret. The SDK handles the token exchange and refresh automatically:

client := client.NewClient(
    option.WithClientID("..."),
    option.WithClientSecret("..."),
    option.WithBaseURL(sdk.Environments.Sandbox),
)

The existing option.WithApiKey(...) option function still works unchanged — no action needed if you’re not switching auth methods. See the Go SDK guide and Authentication to compare both methods.

Changed the VendorQueryRecord.AdditionalData type from map[string]map[string]any to map[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.
