Authentication

Use a Tenklo API key as a Bearer token in the Authorization header.

Authorization: Bearer <NANGO-API-KEY>

Tenklo has two API key types. They are not interchangeable:

• Environment API keys — access a single environment. Manage them under Environment Settings > API Keys. Each key has scopes that control which environment endpoints it can access. A key without the required scope receives a 403 Forbidden response.
• Account API keys — access account-level APIs only. Requests to environment-level APIs with an Account API key return a 403 Forbidden response. Manage them from Account API keys in the dashboard.
