Supported Entities

POST /caliper/v1p2 accepts only the entity types below. If any entity in the envelope uses a known Caliper entity type that is not on this list, the whole envelope is rejected with HTTP 400 and the description The [Type1, Type2] entity types are not supported.

The check does not enter target, referrer, group, membership, extensions, or attributes. A bare IRI has no type and is not judged.

For event payloads and when to send each event, see Caliper Events Reference. For how to send envelopes, see Level 3: Caliper Events.
