Exchange a Refresh Token

  • Available in Paper Trading
  • Available in Production
  • Available to Advisors
  • Supported

A member of the Tradier Brokerage team must approve your application for refresh tokens. This is only available to Tradier Partners. You can email techsupport@tradier.com to start the approval process.

Refresh tokens can be exchanged for access tokens without a customer reauthorizing the application. These tokens should be protected like passwords! You will obtain a refresh token in the same response as an access token.

Unlike other requests to the Tradier API, this request only returns JSON due to the OAuth 2.0 specification and for compatibility with most OAuth clients.

Due to the OAuth specification, this API endpoint uses HTTP Basic Authentication. Your application client Id will serve as your username and the client secret the password. You can learn more about HTTP Basic Authentication on Wikipedia or directly reference the specification.




Header Required Values/Example Default
Content-Type Required application/x-www-form-urlencoded
Authorization Required Basic lhQOWo0RzJUOWc6Z==
Basic HTTP Authentication. Username: Application client Id, Password: Application client secret


Parameter Type Param Type Required Values/Example Default
grant_type Form String Required refresh_token
Value MUST be set to "refresh_token".
refresh_token Form String Required o0d897fusdnjfo28yoi2noi23098j
The refresh token to exchange.
