Client SDK Download Center

Aptia One provides officially generated, strongly-typed client SDKs compiled directly from the canonical OpenAPI 3.1 specification. Using these SDKs eliminates manual HTTP boilerplate, ensures contract fidelity, and detects breaking integration errors at compile time.

Important Architecture Note: OAuth Token Exchange

OAuth 2.0 Token Management

Generated SDKs are strongly-typed API clients focused exclusively on API operations and domain models. The SDK does NOT automatically perform OAuth 2.0 token exchange or cache tokens internally.

Your application or backend service is responsible for:

1. Submitting client credentials (client_id and client_secret) to the AWS Cognito token endpoint.
2. Managing token expiry and refresh schedules.
3. Supplying the resulting Bearer access_token to the SDK's Configuration instance.
