string
header

Your HayInsights API key (prefixed apk_). Create and manage keys in the HayInsights dashboard (Account → API keys).

Send it in the X-API-Key header on every request to /openapi/v1/*. Which data domains you may access and your request quota are both governed by the subscription plan attached to the key — see the Plans & features and Rate limits guides.
