Every Voyant API and SDK authenticates with a Voyant API token. One token works across Cloud, Connect, and Data; its scopes decide what it is allowed to do.

​
API tokens

A token is sent as a bearer token in the Authorization header: 
Authorization: Bearer <your-api-token>
The SDKs do this for you when you pass apiKey: 
import { createVoyantCloudClient } from "@voyant-travel/cloud-sdk";

const client = createVoyantCloudClient({
  apiKey: process.env.VOYANT_API_KEY!,
});
Mint tokens in the dashboard tokens UI, or with the CLI after voyant login. Keep tokens on the server. They carry the scopes that authorize real actions, so they should never ship in a browser bundle.

​
Scopes

Tokens are scoped per service and per action. A route checks the scope it declares against the token’s scopes, and rejects the call if it is missing. Examples:
ActionScope
Send an SMSsms:send
Read a vault secretvault:read
Publish a realtime messagerealtime:publish
Read geography datadata:geo:read
Read SEO datadata:seo:read
Each service page lists the scopes its methods need. Grant a token only the scopes it actually uses.
If a read comes back empty or a call is rejected, check the token’s scopes first. A missing scope is the most common cause, and for some data products an entitlement gap surfaces as empty results rather than an error.

​
Machine-to-machine tokens

Connect supports OAuth client credentials for machine-to-machine flows. Provision a client, then exchange its credentials for a short-lived bearer token: 
import { createVoyantConnectClient } from "@voyant-travel/connect-sdk";

const client = createVoyantConnectClient({ apiKey: process.env.VOYANT_API_KEY! });

const token = await client.oauth.issueToken({ /* client credentials */ });
// token.access_token, token.expires_in, token.scope
Both static API keys and minted access tokens hit the same scope-checked routes. The access token’s scope claim must include the scope the route declares.

​
Short-lived client tokens for browsers

Some services let a browser connect directly without your API key. Realtime is the main example: you mint a short-lived, capability-scoped client token on the server and hand it to the front end, which uses it to open a WebSocket. The API key never leaves your server. See Realtime.

​
Base URL

Every API is served from: 
https://api.voyant.travel
You can override baseUrl on any client for testing or self-hosted environments.

​
CLI credentials

The CLI stores cloud credentials in ~/.voyant/credentials.json (mode 0600), keyed by API URL and organization, so you can be logged into several environments and organizations at once. On every cloud command it resolves a token in this order:
  1. A --token <value> flag.
  2. The VOYANT_CLOUD_API_KEY environment variable.
  3. The stored credential for the resolved API URL and active organization.
The active organization is chosen by --org → VOYANT_CLOUD_ORG → voyant org use → the sole logged-in org. See the CLI overview for login flows and organizations.
