Adapter classifies every piece of ingested data as an evidence type. Each evidence type has a fixed schema regardless of which provider it came from. Evidence types fall into two categories:
  • General — not tied to a single provider. For example, email uses the same schema whether the source is Gmail or Outlook. General types include communication (email, calendar events), files, and assets.
  • Provider-scoped — specific to one integration. Types like github_issue or linear_cycle represent resources that only exist within that provider.
When you query the Search or Context endpoints, each result includes an evidence_type field set to one of the values below.
All evidence_type values
