Assign a role to an identity at a node

POST/portal/v1/accounts/{accountSlug}/applications/{appSlug}/environments/{envSlug}/assignments

Assigns a role to an identity at a specific hierarchy node, granting that role's permissions at the node and — through inheritance — at every descendant node. Authorization is evaluated as rbac.manage_assignments at the target node_id; the node must belong to the current Environment, the identity must have an active membership in it, and the role must be active and non-system (400 for system roles). Optional effective_from/effective_to schedule the assignment; a duplicate identity + role + node triple returns 409. Emits an assignment.created audit event.

Authentication

Bearer TokenAuthorization

JWT access token. Never send alongside X-API-Key: a request carrying both is refused.

Requires capability env_identities.manageDeveloper Console

Create, invite, edit, and remove identities and assign their roles. Granted through an administrator role in the Admin Workspace; a valid token without it is refused with 403.

Production Environments require production_identities.accessDeveloper Console

Access identities in production Environments. Applies to users only, and only in an Environment marked production: its identities are real end users. API keys and identity principals are exempt.

Path Parameters

accountSlugstring Required

The Account's slug. An unknown one answers 404.

appSlugstring Required

The Application's slug within the Account.

envSlugstring Required

The Environment's slug within the Application.

Errors

When the request can't be completed, the response body includes a stable error code you can branch on, and a correlation_id (also sent as the X-Correlation-Id header). Quote the correlation id when you contact support: it identifies the exact request in Canopy's logs.

403account.capability_requiredForbidden
When it happens

The signed-in user's administrator roles do not grant the capability this endpoint requires.

Remediation

Ask an account administrator to grant a role carrying the capability named in the Authentication section, then retry.

403environment.production_identities_forbiddenForbidden
When it happens

The Environment is marked production and the caller is a user without production identity access.

Remediation

Manage these people in the Admin Workspace, or ask an administrator to grant the Production Support role, then retry.
