Tips

  • The API uses JSON-RPC — requests go to user-api.simplybook.me. The Company Login is passed in the X-Company-Login header.
  • If the API plugin is not visible, your plan may not include it. Check your plan features or contact SimplyBook.me support.
  • SimplyBook.me is HIPAA-compliant from the Standard plan — suitable for healthcare providers.
