Individual App Authentication

This section explains how to authenticate your own FYERS account with an individual app and get an access token for all later requests.

Individual apps are created for your own use. Only the creator can log in with the app; no other client can use it. Create the app in the API Dashboard  with a redirect URL that you control. See Create an app.

  • Access tokens expire daily at 6:30 AM. Generate a new token after 6:30 AM for it to remain valid throughout the day.
  • Send app_id:access_token in the HTTP Authorization header on every request after login. See API Standards.
