CPA turns integration into configuration. Because components talk through open, versioned contracts rather than bespoke code, adding a PSP, changing a fraud backend, or updating a compliance rule is a configuration change – not a multi-month engineering project. Link, for example, lets you re-point a stable API contract to a different provider without the caller ever changing.

For enterprises this collapses the cost of switching providers and the risk of being trapped by a single vendor, protecting both margins and negotiating power.
