# [BETA] Get all signals that match the query parameter criteria.

GET https://app.unleash-instance.example.com/api/admin/signals

**Enterprise feature**

**[BETA]** This API is in beta state, which means it may change or be removed in the future.

Returns a list of all signals that match the query parameter criteria.

Reference: https://docs.getunleash.io/api/get-signals

## Authentication

- `Authorization` header (required) — API key needed to access this API
- `Authorization` header (bearer token, required) — API key needed to access this API, in Bearer token format

## Request

### Query parameters

- `from` (string, optional) — The starting date of the creation date range in IS:yyyy-MM-dd format
- `to` (string, optional) — The ending date of the creation date range in IS:yyyy-MM-dd format
- `offset` (string, optional, default: 0) — The number of features to skip when returning a page. By default it is set to 0.
- `limit` (string, optional, default: 50) — The number of feature environments to return in a page. By default it is set to 50. The maximum is 1000.

## Response

### 200

#/components/schemas/signalQueryResponseSchema

- `signals` (list of signalQuerySignalSchema, required) — The list of signals
- `total` (integer, required) — The total count of signals

## Errors

### 401 Unauthorized Error

Authorization information is missing or invalid. Provide a valid API token as the `authorization` header, e.g. `authorization:*.*.my-admin-token`.

- `id` (string, optional) — The ID of the error instance
- `name` (string, optional) — The name of the error kind
- `message` (string, optional) — A description of what went wrong.

## Types

### signalQuerySignalSchema

An object describing a signal enriched with source data.

- `id` (integer, required) — The signal's ID. Signal IDs are incrementing integers. In other words, a more recently created signal will always have a higher ID than an older one.
- `createdAt` (string, required) — The date and time of when the signal was created.
- `source` (enum, required) — The signal source type. Should be used along with `sourceId` to uniquely identify the resource that created this signal.
  - Allowed values: `signal-endpoint`
- `sourceId` (integer, required) — The ID of the source that created this signal. Should be used along with `source` to uniquely identify the resource that created this signal.
- `payload` (SignalQuerySignalSchemaPayload, optional) — The payload of the signal.
- `tokenName` (string, optional, nullable) — The name of the token used to register this signal.
- `sourceName` (string, optional, nullable) — The name of the source that registered this signal.
- `sourceDescription` (string, optional, nullable) — A more detailed description of the source that registered this signal.

### SignalQuerySignalSchemaPayload

The payload of the signal.
