Parameters

Parameter	Type	Description
config	Configuration	-
backchannelAuthenticationResponse	BackchannelAuthenticationResponse	Backchannel Authentication Response obtained from initiateBackchannelAuthentication
parameters?	Record<string, string> | URLSearchParams	Additional parameters that will be sent to the token endpoint, typically used for parameters such as scope and a resource (Resource Indicator)
options?	BackchannelAuthenticationGrantPollOptions	-

Returns

Promise<TokenEndpointResponse & TokenEndpointResponseHelpers>

Example

let config!: client.Configuration
let scope!: string
let login_hint!: string // one of login_hint, id_token_hint, or login_hint_token parameters must be provided in CIBA

let backchannelAuthenticationResponse =
  await client.initiateBackchannelAuthentication(config, {
    scope,
    login_hint,
  })

// OPTIONAL: If your client is configured with Ping Mode you'd invoke the following after getting the CIBA Ping Callback (its implementation is framework specific and therefore out of scope for openid-client)

let { auth_req_id } = backchannelAuthenticationResponse

let tokenEndpointResponse =
  await client.pollBackchannelAuthenticationGrant(
    config,
    backchannelAuthenticationResponse,
  )
