Endpoints, fields, and behavior may still change, so avoid depending on it in production. Returns a signed link to a thread's screenshot that works for one year, for pasting somewhere that outlives the one-hour links in [List comments](/api-reference/list-comments). Each call creates a new link, and a link can't be revoked before it expires. The link opens the screenshot for anyone who has it, so share it only where that's fine. 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}/chat-screenshot-url 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}/chat-screenshot-url: post: summary: Create comment screenshot link description: >- This API is in beta.
