Classifications

Update a classification

PATCH/classifications/{id}
classifications:writeupdate_classificationIdempotent

Renames the classification and returns it. A label another classification already has, ignoring case, returns 422. Callers without the manage-classifications permission get 403 missing_permission; holders of the assign-only permission can't rename. dry_run shows the result without saving it. Emits classification.updated and sends no email. Sending the previous label undoes it.

Path parameters

  • idintegerRequired#

    The classification's id. Classifications are keyed by integer ids, not UUIDs: a whole number from 1 to 2147483647.

Query parameters

  • dry_runboolean#

    Validate and run the call without committing it, returning what the real call would return with meta.dry_run set.

Request body

application/json, required · ClassificationUpdate

  • labelstring#

    The new name. Letters, digits, spaces and - . , & only. Another classification can't have the same label, ignoring case.

  "label": "Elective Professional Investor"
