What is an entity_id?

An entity is any subject you store knowledge about: a user, org, product, or topic. Use a stable ID like ent:user_123.

​
Best practices

  • Prefix with ent: and a domain-specific namespace (e.g., user_, org_).
  • Keep IDs stable across sessions. Do not use ephemeral chat IDs.
  • Use namespace per app/env (e.g., default, staging).

​
Naming and display

You can attach a human name via the profile type or in provenance: 
{"type":"profile","entity_id":"ent:user_123","text":"Alex"}

​
Merge / alias

If two IDs refer to the same subject, store a fact like subject=ent:user_abc, predicate=alias_of, object_entity=ent:user_123, then query by either.

​
Scoping

  • Org is inferred from your API key.
  • Scope traffic via X-Flumes-Agent and namespace.
