Reference: https://docs.ocpplab.io/api-reference/emsp/token-groups/assign-network ## Authentication - `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer `, where token is your auth token. ## Request ### Path parameters - `group_id` (integer, required) — The token group's ``id``. ### Headers - `Idempotency-Key` (string, required) — A unique key you choose for this call, e.g. a UUID. Retrying with the same key returns the first result instead of acting twice. ### Body (application/json) This endpoint expects a TokenGroupNetworkAssign. - `network_id` (integer, required) ## Response ### 201 The assigned network. - `network_id` (integer, required) - `group_id` (integer, required) - `organization_id` (string, required) - `name` (string, required) - `network_type` (string, required) - `owner_country_code` (string, required) - `owner_party_id` (string, required) - `publish_state` (string, required) - `publicly_accessible` (boolean, required) - `assigned_at` (datetime, required) - `description` (string, optional, nullable) - `parent_network_id` (integer, optional, nullable) ## Errors ### 401 Unauthorized Error Missing or invalid Bearer token - `detail` (string, required) — Human-readable error message returned by the API. ### 404 Not Found Error Token group not found for your organization - `detail` (string, required) — Human-readable error message returned by the API. ### 409 Conflict Error The network is already assigned to the group - `detail` (string, required) — Human-readable error message returned by the API. ### 422 Unprocessable Entity Error The request does not match the schema - `detail` (list of ValidationError, optional) — One entry per invalid field. ### 429 Too Many Requests Error Gateway rate limit reached; retry after the given seconds - `detail` (string, required) — Human-readable error message returned by the API. ### 502 Bad Gateway Error Gateway unreachable, failing, or misconfigured - `detail` (string, required) — Human-readable error message returned by the API. ### 504 Gateway Timeout Error Gateway timed out - `detail` (string, required) — Human-readable error message returned by the API. ## Types ### ValidationError Why one field is invalid. - `loc` (list of ValidationErrorLocItems, required) — Where the field is: ``body`` / ``query`` / ``path`` / ``header``, then its name. - `msg` (string, required) — What is wrong, in English. - `type` (string, required) — Machine-readable error code, e.g. ``missing``. - `input` (any, optional) — The value that was sent. - `ctx` (ValidationErrorCtx, optional) — Details of the rule that failed, e.g. `{"le": 200}`. ### ValidationErrorLocItems ### ValidationErrorCtx Details of the rule that failed, e.g. `{"le": 200}`. ## Examples **Request** ```json { "network_id": 21 } ``` **Response** ```json { "network_id": 21, "group_id": 12, "organization_id": "550e8400-e29b-41d4-a716-446655440000", "name": "Fleet fast chargers", "network_type": "TENANT", "owner_country_code": "NL", "owner_party_id": "OCP", "publish_state": "UNPUBLISHED", "publicly_accessible": false, "assigned_at": "2026-09-30T10:00:00Z", "description": "DC sites only", "parent_network_id": 20 } ``` **SDK Code** ```python import requests url = "https://api.ocpplab.io/emsp/token-groups/12/networks" payload = { "network_id": 21 } headers = { "Idempotency-Key": "5d1f7c2e-8b3a-4e6f-9c0d-1a2b3c4d5e6f", "Authorization": "Bearer ", "Content-Type": "application/json" } response = requests.post(url, json=payload, headers=headers) print(response.json()) ``` ```javascript const url = 'https://api.ocpplab.io/emsp/token-groups/12/networks';
