# List API Keys

GET https://api.getthera.com/companies/{companyId}/api-keys

Lists every API key on the company, active and revoked, including legacy ones.

Reference: https://docs.getthera.com/thera-api/company/apikey-api/list-api-keys

## Authentication

- `X-Thera-API-Key` header (required) — API Key authentication via header

## Servers

- `https://api.getthera.com` (Production, default)
- `https://api.staging.getthera.com` (Staging)

## Request

### Path parameters

- `companyId` (string, required)

## Response

### 200

- `list of ApiKeySummary`

## Types

### ApiKeySummary

A key as shown on the settings page. The secret itself is never returned here.

- `id` (string, required) — Identifies the key in every other call. The service account for a self-serve key, and the stored hash of the token for a legacy one, which has no service account. The raw secret is never exposed either way.
- `legacy` (boolean, required) — True for a key issued before self-serve. Those hold full write access on the /external endpoints and cannot be replaced in place, only revoked and reissued.
- `name` (string, required)
- `last4` (string, required)
- `createdAt` (string, required)
- `active` (boolean, required)
- `createdByUserId` (string, optional)
- `createdByName` (string, optional) — Display name of the admin who issued the key, resolved for the settings page.
- `lastUsed` (string, optional)
- `expiresAt` (string, optional)
