API ReferenceSegments

List segments

Get all audience segments for the project, newest first. This endpoint is not paginated — it returns a bare array of every segment.

GET
/segments

Authorization

ApiKeyAuth

AuthorizationBearer <token>

API Key authentication. The project is automatically derived from the key.

/v1/track requires a public key (pk_*) — it is the one endpoint intended for client-side use, and a secret key is rejected there with 401.

Every other endpoint requires a secret key (sk_*) and rejects public keys with 401.

So the two key types are not interchangeable in either direction: pick the key that matches the endpoint you are calling.
