# Send an OCPP command to a charger

POST https://api.ocpplab.io/proxy/ocpp/commands/{command}
Content-Type: application/json

Queues one OCPP CALL for the charger through the OCPP gateway. Poll `GET /proxy/ocpp/commands/{tracking_id}` for the charger's answer. Organization is taken from the Bearer JWT.

Reference: https://docs.ocpplab.io/api-reference/proxy/commands/send-ocpp

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `command` (string, required) — OCPP action, e.g. ``RemoteStartTransaction`` or ``Reset``.

### Headers

- `X-Request-Id` (string, optional, nullable)
- `X-Correlation-Id` (string, optional, nullable)

### Body (application/json)

This endpoint expects a SendOcppCommandRequest.

- `charge_point_id` (string, required) — Charger that receives the OCPP CALL.
- `ocpp_version` (enum, optional, nullable) — ``v16`` → OCPP 1.6, ``v201`` → 2.0.1, ``v21`` → 2.1. Omit to use the charger's registered version (1.6 if it has none).
  - Allowed values: `v16`, `v201`, `v21`
- `payload` (map from string to any, optional) — OCPP action payload, sent as the CALL body.
- `idempotency_key` (string, optional, nullable) — Replays return the first dispatch instead of sending again.

## Response

### 200

Successful Response

- `charge_point_id` (string, required) — Charger the CALL was sent to.
- `ocpp_version` (string, required) — OCPP version the CALL was sent in.
- `commands` (list of OcppCommandItem, required) — The CALLs queued for the charger.

## Errors

### 400 Bad Request Error

Rejected by the gateway (business rule)

- `detail` (string, required) — Human-readable error message returned by the API.

### 401 Unauthorized Error

Missing or invalid Bearer token

- `detail` (string, required) — Human-readable error message returned by the API.

### 404 Not Found Error

Not found for this organization

- `detail` (string, required) — Human-readable error message returned by the API.

### 409 Conflict Error

Already exists or not allowed in its current state

- `detail` (string, required) — Human-readable error message returned by the API.

### 422 Unprocessable Entity Error

Validation Error

- `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

### OcppCommandItem

One OCPP CALL accepted by the gateway.

- `action` (string, required) — OCPP action sent, e.g. ``Reset``.
- `tracking_id` (string, required) — Pass to `GET /proxy/ocpp/commands/{tracking_id}`.
- `status` (string, required) — Dispatch status, e.g. ``queued``.
- `replayed` (boolean, optional, default: false) — True when an ``idempotency_key`` replay returned an earlier dispatch.

### 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}`.
