Secure Multi-Token API Authentication & Downstream Integration

Controlled handling of two authentication tokens per request, so downstream access stays secure and reliable.

API security & integrationEnterprise API modernization

The challenge

API requests carried two authentication tokens with different purposes. Without controlled separation and validation, downstream access and request processing could be disrupted by missing or invalid credentials.

The architecture

IBM API Connect and IBM DataPower enable controlled token extraction, primary API authentication, separate downstream-token handling, secure forwarding, validation, and error handling.

The business impact

Centralized API governance, stronger security enforcement, reusable API policies, and JSON-to-XML transformation support a more consistent integration model with fewer backend changes.
