Acoustic Connect API
The GraphQL API for Acoustic Connect — the platform's contact, consent, audience, reference-set, product-catalog, product-performance and signal surface. A single POST endpoint at the region host root, authenticated with an X-API-Key header generated in Connect under Administration > General settings > API keys. Three regional endpoints (us-east-1, ap-southeast-2, eu-central-1). Schema introspection is authentication-gated.
