Authentication

Base URL

All public API requests use:

https://api.nylon.dev/v1

Send your Nylon API key in the Authorization header of every request:

Authorization: Bearer nylon_live_YOUR_API_KEY

API keys are associated with your Nylon user account and can access that account’s connected profiles.

Create and manage keys from the Nylon API page. Use a descriptive name so you can identify the application or environment using each key.

Create separate keys for development, staging, and production. This lets you revoke one environment without interrupting the others.

The API returns 401 Unauthorized when the bearer token is missing, malformed, revoked, or invalid.
