# Get Customer by ID

`GET /customers/{id}`

## Request

- Base URL: `https://api.smartroutes.io/v2`
- URL: `https://api.smartroutes.io/v2/customers/{id}`
- Auth: none declared

Returns one customer from your depot by its SmartRoutes `id`, nested under a `customer` key. The response includes the customer's details plus its capacities, skills, tags, time windows and custom fields. If you only have the account reference, find the customer with `GET /customers` first. An `id` that doesn't exist in your depot returns `404 RESOURCE_NOT_FOUND`.

## Path parameters

- `id` string, required

## Response `200`

Successful response

## Other responses

- `400`: Invalid input. The request body failed validation.
- `403`: Forbidden. Returned for rate-limit exhaustion (`name = FORBIDDEN`, with `details.retry_after_seconds` and `Retry-After` header) and permission gate failures (`name = PERMISSION`). Inspect `name` to disambiguate. Send `x-sr-api-features: rate-limit-429` to receive `429 RATE_LIMIT_EXCEEDED` for the rate-limit case instead, leaving `403` to mean permission failures only — see [API Features](#section/Getting-started/API-Features).
- `404`: The requested resource was not found.
- `429`: Rate limit exceeded (`name = RATE_LIMIT_EXCEEDED`). **Only returned to callers that opt in** with the `x-sr-api-features: rate-limit-429` request header; without it the same condition returns `403` with `name = FORBIDDEN` and an otherwise identical body. See [API Features](#section/Getting-started/API-Features).
- `500`: An unexpected server error occurred. The body carries only `name` and `description`: internal details are never returned.
