Benchling Events API

openapi: 3.0.3
info:
  title: Benchling AA Sequences Events API
  description: 'Curated OpenAPI for the Benchling life-sciences R&D cloud (LIMS + ELN + registry + inventory + workflows). Benchling exposes a tenant-scoped REST API at https://{tenant}.benchling.com/api/v2 covering the same objects scientists work with in the UI: DNA/RNA/protein sequences, custom entities and the registry, sample inventory, notebook entries, assay results and runs, lab automation, workflow tasks, requests, plus an events stream and Benchling Apps/webhooks.


    Every path and method in this document is grounded in Benchling''s own published OpenAPI specification (benchling.com/api/v2/openapi.yaml). This is a curated, representative subset of the full ~325-path Benchling spec - the core CRUD, bulk, and action endpoints per resource - not the exhaustive spec. For the authoritative, complete, always-current definition, fetch Benchling''s published spec.


    Authentication: personal user API keys use HTTP Basic (Authorization: Basic {api_key}); Benchling Apps use OAuth2 client credentials (POST /api/v2/token -> Bearer {access_token}). OIDC is available to act as a specific user with their permissions. Note the {tenant} placeholder in the server URL must be replaced with your Benchling tenant subdomain.'
