API Keys

API keys are a long-lived, revocable alternative to the session-token login flow, intended for third-party server-to-server integrations. Instead of logging in with an email and password to obtain a session token (which expires after 14 days), an integration sends a single static key on every request.

A key is bound to a user in your company and authenticates as that user — it inherits exactly that user’s permissions (user group / ACL). Choose the bound user carefully; give integrations a dedicated, least-privilege user where possible.

Using a key

Send the key as a Bearer token, exactly like a session token. API keys are prefixed with flk_:

Authorization: Bearer flk_3pQ8...Zr

curl https://fmc.flylogs.com/v1/flights.json \
  -H "Authorization: Bearer flk_3pQ8...Zr"

Keys do not expire on inactivity and are not affected by logout. A key stops working only when it is revoked or, if an expiry date was set, after that date passes.

Managing keys

API keys are created and revoked by a company administrator in the Flylogs app, under Company Settings → API → API keys. They are not managed with an API key itself — management requires an interactive admin session.

The management endpoints below sit under the manager routing prefix and are used by the app; they are documented here for completeness.

List keys

GET /manager/api_keys.json

Returns the company’s keys. The secret itself is never returned — only a short, non-secret key_prefix for identification.

Response

{
  "keys": [
    {
      "ApiKey": {
        "id": "8f1c...",
        "user_id": 1234,
        "name": "Ops dashboard",
        "key_prefix": "flk_3pQ8",
        "last_used_at": 1718450000,
        "expires": null,
        "revoked": false,
        "created": 1718000000
      },
      "User": { "id": 1234, "email": "integration@example.com" }
    }
  ]
}

Create a key

POST /manager/api_keys/add.json

Issues a new key. The plaintext key is returned once, in this response only, and cannot be recovered afterwards. Store it immediately.

Request Body

Field	Type	Required	Description
name	string	Yes	Human label for the integration (e.g. `"Zapier"`)
user_id	number	Yes	A user in your company the key will authenticate as
expires	number	No	Unix timestamp after which the key is rejected. Omit for a key that never expires

Response

{
  "result": true,
  "message": "Store this key now — it will not be shown again.",
  "key": {
    "id": "8f1c...",
    "name": "Ops dashboard",
    "user_id": 1234,
    "key_prefix": "flk_3pQ8",
    "expires": null,
    "plaintext": "flk_3pQ8XnX...full-secret...Zr"
  }
}

Example

curl -X POST https://fmc.flylogs.com/v1/manager/api_keys/add.json \
  -H "Authorization: Bearer <admin-token>" \
  -H "Content-Type: application/json" \
  -d '{"name": "Ops dashboard", "user_id": 1234}'

Revoke a key

POST /manager/api_keys/revoke/{id}.json

Permanently disables a key. Revocation is immediate and irreversible; the key is retained for audit but is rejected on every subsequent request.

Path Parameters

Parameter	Type	Description
id	string	The key’s `id` (not the secret)

Response

{ "result": true, "message": "API key revoked" }

Access control

Capability	Who
Create / list / revoke API keys	Company Administrators & Operations Managers (user group ≤ 110)
What a key can do once issued	Whatever the bound user’s user group permits

A key can only be bound to a user in the same company as the administrator creating it. Cross-company keys are rejected.

API keys vs. session tokens

	API key	Session token
Obtained by	Admin issues it in API key management	`POST /login` with email + password
Lifetime	Until revoked (optional expiry)	14 days / until logout
Identity	Bound user	Logged-in user
Best for	Unattended server-to-server integrations	Interactive clients (e.g. the NEO app)
2FA / IP allowlist	Not applicable	Applies to interactive logins
