The connected surfaces of the organization

GET /api/auth/surfaces/{organizationId}

The connected surfaces of the organization (Settings › Apps › Slack): each person's delegation to a core service they reach from somewhere else — the Slack app now; Teams, WhatsApp or a voice line later — with the surface it is for, since when and with which scopes: every delegation for an owner or admin, the caller's own for any other member.

These are agent grants recorded by PUT /api/auth/delegations/…, and GET /api/auth/agents/:organizationId leaves them out; one is withdrawn with DELETE /api/auth/agents/:organizationId/:clientId/:userId, after which the surface's next exchange is refused. Which account on the surface a delegation is for (the Slack workspace's name) is the surface's own data, read from it. 403 NotAMember for anyone outside the organization.

Access

Requires a signed-in session: Any active member of the organization, checked against its membership by the route: an owner or admin reads every delegation, anyone else their own

How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.

AI agent tool

No agent tool. Which people have connected Slack (and later other chat and voice surfaces) is read in Settings › Apps › Slack in the admin; the MCP server does not reach the auth service, and an agent is not a surface.

Connecting an agent: AI agents.

The panel writes this call in other languages. It does not send it: Manifold's APIs do not take calls from a web page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: auth-service.openapi.json. Base URL https://auth.getmanifold.io.

Errors

Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.

`401`

Refusal	What it means	What to do
`Unauthorized` reason	The token is missing, expired or not one Manifold issued.	Get a fresh token and send the call again.
`TokenAlreadyUsed` tokenId	A single-use app token was already spent.	Mint a new token for this call.

`402`

Refusal	What it means	What to do
`SubscriptionRequired` status	The organization's subscription has lapsed, so writes are refused.	An owner settles billing. Reads still work meanwhile.

`403`

Refusal	What it means	What to do
`NotAMember`	The person is not a member of this organization.	Check the organization, or invite them first.
`TenantRequired` userId	The token names no organization.	Choose the organization, then get a new token.
`ScopeRequired` required	The token's roles do not grant the scope this call needs.	Ask an owner or admin for a role that grants it.

`409`

Refusal	What it means	What to do
`MirroredFromSource` source	This area is fed by your source system until the organization goes live.	Make the change in the source system, or go live first.

`503`

Refusal	What it means	What to do
`RequestLogUnavailable` tokenId, reason	The service could not record the request, so it did nothing.	Try again shortly.
