Without embed_origins no page may frame them. An embedded page sends its parent window messages when control changes and when it connects or disconnects (see the browser guide). Either link opens the window to anyone who holds it until it expires; detaching the window ends it early. Minting takes being the browser's creator or a role with sandboxes:exec. ## OpenAPI ````yaml /langsmith/langsmith-platform-openapi.json post /api/v2/sandboxes/browsers/{name}/attachments/{attachment_id}/links openapi: 3.1.0 info: title: LangSmith description: >+ The LangSmith API is used to programmatically create and manage LangSmith resources. ## Host https://api.smith.langchain.com ## Authentication To authenticate with the LangSmith API, set the `X-Api-Key` header to a valid [LangSmith API key](https://docs.langchain.com/langsmith/create-account-api-key#create-an-api-key). version: 0.1.0 servers: - url: / security: [] tags: - name: run x-group: Tracing - name: runs x-group: Tracing - name: sessions x-group: Tracing - name: tracer-sessions x-group: Tracing - name: threads x-group: Threads - name: datasets x-group: Datasets - name: examples x-group: Datasets - name: evaluators x-group: Evaluation - name: experiment-view-overrides x-group: Evaluation - name: experiments x-group: Evaluation - name: annotation-queues x-group: Feedback & Annotation - name: annotation_queues x-group: Feedback & Annotation - name: feedback x-group: Feedback & Annotation - name: feedback-configs x-group: Feedback & Annotation - name: alert_rules x-group: Monitoring - name: bulk-exports x-group: Monitoring - name: charts x-group: Monitoring - name: commits x-group: Prompts & Playground - name: directories x-group: Prompts & Playground - name: hub_environments x-group: Prompts & Playground - name: playground-settings x-group: Prompts & Playground - name: prompt-webhooks x-group: Prompts & Playground - name: prompts x-group: Prompts & Playground - name: tag-transitions x-group: Prompts & Playground - name: comments x-group: Prompt Hub - name: likes x-group: Prompt Hub - name: optimization-jobs x-group: Prompt Hub - name: ownerships x-group: Prompt Hub - name: repos x-group: Prompt Hub - name: settings x-group: Prompt Hub - name: tags x-group: Prompt Hub - name: integrations x-group: Integrations & Tools - name: mcp x-group: Integrations & Tools - name: mcp_vendors x-group: Integrations & Tools - name: oauth x-group: Integrations & Tools - name: tools x-group: Integrations & Tools - name: gateway-policies x-group: LLM Gateway - name: sandboxes x-group: Sandboxes - name: issues x-group: Issues - name: issues-agent x-group: Issues - name: Organizations x-group: Administration - name: SCIM Tokens x-group: Administration - name: TTL Settings x-group: Administration - name: access_policies x-group: Administration - name: api-key x-group: Administration - name: audit-logs x-group: Administration - name: auth x-group: Administration - name: aws_marketplace x-group: Administration - name: data_planes x-group: Administration - name: me x-group: Administration - name: orgs x-group: Administration - name: service-accounts x-group: Administration - name: tenant x-group: Administration - name: ttl-settings x-group: Administration - name: usage-limits x-group: Administration - name: workspaces x-group: Administration - name: ace x-group: System - name: backfills x-group: System - name: features x-group: System - name: info x-group: System - name: model-price-map x-group: System - name: public x-group: System - name: fleet orgs - name: fleet secrets - name: fleet tenants - name: fleet threads x-hidden: true - name: fleet users - name: productfeedback x-hidden: true - name: usage paths: /api/v2/sandboxes/browsers/{name}/attachments/{attachment_id}/links: post: tags: - sandboxes summary: Create links to a browser window (Beta) description: >- Beta: mint a view link and an act link for one window, as every attachment response does, with a chosen lifetime and the origins allowed to embed the window's pages in an iframe.
