# List an application's assignments in an organization

`GET /v1/organizations/{org_id}/applications/{application_id}/assignments` · permission `organizations:write`

Lists the memberships and directory groups the application is assigned to in the organization, oldest first. Only forward pagination is supported: `before` and an `order` other than `asc` return `422`. The cursor is bound to this organization and application. There is no endpoint for reading a single assignment; assignments are immutable and only deleted.

## Request

|---|---|---|---|
| `org_id` | path | yes | Organization ID (`org_…`). |

| `limit` | query | no | 1–100, default 20. |
| `after` | query | no | Cursor from `list_metadata.after`. |

No request body.
