exchangeAuthorizationCodeWithPkce

client.exchangeAuthorizationCodeWithPkce({
  code: string,
  redirectUri: string
})

About this command

Get an access token by providing an authorization code.

Only available if PKCE is enabled or if the authorization code was retrieved from the loginWithSocialProvider method.

Passwordless flow

PKCE expects the same client context to complete both steps of the exchange. This means that if a user starts the flow on one device and then tries to complete it on a different device (e.g., by switching from mobile to tablet), the exchange fails.

Examples

client
  .exchangeAuthorizationCodeWithPkce({
    code: 'QVVUSE9SSVpBVElPTl9DT0RF',
    redirectUri: 'https://www.example.com/login/callback'
  })
  .then(authResult => {
    // Retrieve the access token
  })
  .catch(err => console.error(err))

Parameters

code string

The authorization code.

redirectUri string

The URL the user will be redirected to after getting the access token.

Response

Type: Promise<AuthResult>

AuthResult object fields

Field Type Description

accessToken

string

The user’s newly-generated access token.

This a security token that gives access to authorized resources without further identification. It is represented as a JSON Web Token (JWT).

expiresIn

number

The lifetime of the access token (in seconds).

expiresIn always equals the access token lifetime set on your First-party Identity client in the ReachFive Console.

tokenType

string

The type of token that is issued.

This is always Bearer.

refreshToken

string

The user’s newly-generated refresh token.

A refresh token is not present unless you are implementing the refresh token grant. This is only possible when the offline_access scope is requested.

idToken

string

The user’s newly-generated ID token. This is a security token that contains authentication claims about the user. It is represented as a JSON Web Token (JWT).

Claims are pieces of information made about a particular subject.

For example, ID tokens might contain a claim called name that makes the claim that the name of the user authenticating is "Nicole Dubois".

{
    "sub": "987654321",
    "name": "Nicole Dubois",
    ...
}

idTokenPayload

JSON

The body of the ID token which outlines the claims. See ID token payload for more details.

For a full list of claims, check out the JWT Claims Registry.

code

string

The authorization code received from the initial authorization call.

state

string

An opaque value used to maintain state between the request and callback. The authorization server includes this value when redirecting the user-agent back to the client.

stepUpToken

string

The step up token needed to complete the stepup flow.

amr

string

The Authentication Method Reference (amr). When using MFA, the mfa value must be present.

For more on amr values, see here.

providerName

string

The name of the social login provider used to log in.

Example

kakaotalk

This is only relevant for SLO and is not included in the auth response for other flows.

providerAccessToken

string

The access token from the social login provider.
