Endpoints, fields, and behavior may still change, so avoid depending on it in production. Adds your reaction with an emoji to a comment, or removes it when you already reacted with that emoji. Calling it twice undoes the first call, so don't retry it blindly. Any text of up to 16 characters is accepted as `emoji`. 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 post /api/apps/{app_id}/comments/threads/{thread_id}/messages/{message_id}/reactions 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}/reactions: post: summary: Toggle comment reaction description: >- This API is in beta.
