Use this endpoint when you want to change blocks, title, recipient, attachments, or other draft fields without creating a new version. For a new version (duplicate + apply body), use Create new version of proposal — POST /v3/proposals/{uuid}. To update only the JSON data metadata blob with a shallow merge, use Patch proposal data.

​

Eligibility

• The proposal must exist (404 if the UUID is unknown).
• The authenticated user must be allowed to edit the proposal (401 if not).
• company_id in the body must match the proposal’s company (400 if not).
• Status must be draft or template. Other statuses return 409 (e.g. active, accepted).
• withdrawn proposals return 400.

​

Request body

The body is strict: only documented fields are accepted; extra keys return 400 with error.issues describing each problem (field path and message).

• company_id (number, required on every request) — must match the proposal’s company.
• At least one other field is required besides company_id (empty patches are rejected).

All other fields match Create proposal in shape, but they are optional: send only the keys you want to change. Omitted keys are left as-is on the server. Not accepted on this endpoint

• creator_email — use Create proposal only.
• status — not used for publishing; see warning above.

language

• Optional on the patch if the proposal already has a language and you are not changing blocks that depend on the content library.
• If you send blocks with content_id, you must supply language in the body or the proposal must already have a language stored.

Common body fields
