Authentication
Bearer tokens, API key prefixes, and what a key can reach.
All requests require a Bearer token in the Authorization header.
Bearer token
Authorization: Bearer pc_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxAPI keys are prefixed with pc_live_.
Creating a key
Generate one from the dashboard's Developers settings, or via POST /api-keys — see API Key Endpoints. Key management itself needs a signed-in dashboard session: a key cannot mint or revoke another key.
Access scope: API keys can access campaign, asset, recipient, rendering, analytics, and webhook endpoints. Billing, profile, and account management are available only through the dashboard.
