Update a user
Label an end user with a display name and/or email so your partner dashboard shows something readable instead of an opaque hash.
Optional and unmetered — retrieval and isolation still key off the
hashed ID. Send a string to set a field, null to clear it, or omit
it to leave it unchanged.
Authorizations
A scoped Integration key, prefixed cint_. Send as
Authorization: Bearer cint_... on every request. Server-side only.
Legacy personal cmem_... keys remain accepted during migration;
team/org-scoped cmem_... keys are not valid on this API.
