The day the API stopped working, everything froze. Calls failed. Services stalled. Customers waited. The root cause wasn’t downtime. It was a broken API token policy under new CPRA rules nobody had fully mapped.
API tokens are the keys to your systems. In a CPRA-compliant world, those keys carry legal weight. California’s privacy law doesn’t just hit databases and front-end forms. It impacts how you create, store, rotate, and retire API tokens. A token can expose personal data in a tiny string of characters. Mishandling it means both a security breach and a compliance violation.
The California Privacy Rights Act adds scope to existing protections. For API design, that means tighter controls on access scope, purpose limitation, and deletion workflows. Each API token you issue should be tied to a defined purpose. An unused but active token is not harmless—it’s a risk that could violate CPRA’s data minimization principle.
Start by mapping every API token in your system. Identify what personal data each can touch. Remove tokens that no longer serve a justified purpose. Design your issuance process so that tokens expire by default, with renewal requiring explicit reason and review. This builds a natural compliance wall into your architecture.
Encryption isn’t optional. Tokens in storage must be encrypted at rest. Tokens in transit should pass through encrypted channels. Access logs must track when and by whom each token is used. Under CPRA, these logs might need to support consumer requests for access or deletion of data, which means your logging must reference tokens without leaking them.
