Endpoints, fields, and behavior may still change, so avoid depending on it in production. Replaces the text of a comment you wrote and sets its `edited_at`. Only the author can edit a comment, so replies from the builder agent can't be edited. `mentioned_emails` records who the comment mentions. Only emails that [List mentionable users](/api-reference/list-mentionable-users) returns are kept, and the rest are dropped without an error. Mentioning someone sends them no email or notification, and responses never return the list. The list you send replaces the comment's previous mentions. The response's `reactions` is always empty, even when the comment has reactions. Read them from [List comments](/api-reference/list-comments). Anyone with the app open in the builder sees the change right away. This is limited to 120 requests per minute per app, shared by every other comments endpoint. A signed-in session has its own limit, and every personal access token for the workspace shares one. Some workspaces have a different limit. Every request that counts against the limit gets `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset` (Unix time in seconds) headers, and a `429` also gets `Retry-After` in seconds. If the limiter itself is unavailable, requests go through without these headers. Call this as an editor of the app, with a personal access token sent as a Bearer token or from a signed-in session. Viewers in the app's workspace, read-only tokens, and workspace API keys are refused. ## OpenAPI ````yaml /developers/references/app-management/app-management-openapi.json patch /api/apps/{app_id}/comments/threads/{thread_id}/messages/{message_id} openapi: 3.1.0 info: title: Base44 App Management API version: 1.0.0 servers: - url: https://app.base44.com security: - PersonalAccessTokenAuth: [] paths: /api/apps/{app_id}/comments/threads/{thread_id}/messages/{message_id}: patch: summary: Edit comment description: >- This API is in beta.
