Update Person
People
Update Person
Assert claim values directly on a person. Asserted claims are sticky — the derivation engine will not overwrite them from later observations.
PATCH
Update Person
:id may be an entity UUID, email, domain, or LinkedIn URL. Identifier fields on the body attach to the entity. Every other field is asserted as a claim.
Body
Any subset of identifier fields (email, linkedin_url, linkedin_member_id, hubspot_id, pipedrive_id, apollo_id, attio_id) plus any claim fields (first_name, last_name, job_title, company, seniority, department, city, country, phone, pipeline_stage, etc.).
To clear a claim, pass null for its value. The claim is invalidated rather than deleted, so prior values remain auditable.
Response
id and entity_id are returned and always carry the same value (the entity UUID). GET /v2/people returns only id.
The write model in one line
Observations record what happened. Assertions throughPOST and PATCH declare what is true now. Both land in the same customer graph, both show up in /v2/accounts/:id, and asserted facts stick until you change them.
