A `tenant_viewer` is read-only and gets 403. Saves name, description, graph. Each save bumps `version`. A flow that is the Partner API's KYC policy can be changed by an admin only (403). **Auth:** dashboard session (`Authorization: Bearer `). Not available with a partner API key. ## OpenAPI ````yaml /openapi-console.json put /v1/flows/{flow_id} openapi: 3.1.0 info: title: Sahl Console API version: 0.1.0 description: >- **Used by the Sahl console. Not available with partner API keys. Contact Sahl if you need programmatic access.** These are the routes the Sahl console calls with a signed-in user's session. They are documented so that a developer or a workspace admin can see what the console does, with the real request and response models. They are **not** part of the [Partner API](/api-reference/introduction): an API key is refused here (401), there is no try-it, and the shapes can change with the console. Authentication: `Authorization: Bearer `, the JWT the console gets from `POST /v1/auth/login` (30 minutes; renewed with `POST /v1/auth/refresh`, refresh token valid 7 days). There is no cookie. The role of the user is read from the user's record on every call, not from the token. Every call is scoped to the workspace of the user. Common answers: 401 (no or bad session), 403 `Insufficient permissions` (role), 422 (validation), 429 (100 requests per minute and IP). Error bodies have the same three shapes as the Partner API: see [Errors](/errors). servers: - url: https://app.sahlfinancial.com/api description: Console host.
