API Key Authentication

API Keys provide a simple, long-lived credential for programmatic access. They are ideal when your backend service needs to call the FileSpin API without user interaction.

curl -H "X-FileSpin-Api-Key:{API_KEY}" \
  https://app.filespin.io/api/v1/assets

Send API requests with the API Key in the HTTP header:

X-FileSpin-Api-Key:{API_KEY}

Where {API_KEY} should be replaced with your API Key.

When to use:

  • Backend services and cron jobs
  • Server-to-server integrations
  • Scenarios where a user is not present and API key can be used securely

How to obtain: Get the API Key from the FileSpin Dashboard under Settings → API Keys.

tip

API Keys do not expire automatically, but can be revoked at any time from the Dashboard.
