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.

Errors

When the request can't be completed, the response body includes a stable error code you can branch on.

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.
