Link keeps adapter logic in versioned templates and a declarative filter chain rather than in per-vendor code or deploys. To integrate or change a provider, you define mapping rules that translate a protocol into that provider's request and response format – configuration that can be updated without shipping application code.

Where other CPA services own a capability (Guardian owns tokenization, Specter owns decisioning), Link owns the connection, so integration stops being an engineering bottleneck.
