The flow endpoint is used to interact with the user in a sign-on workflow. Flow endpoint operations are used only to implement custom authentication UIs. OIDC/OAuth 2 and SAML requests initiate the flow and redirect the browser to the custom authentication UI (which is configured in the application through the application’s loginPageUrl property).

Common sign-on actions

Login actions

The flow endpoint can initiate login actions that specify the operations required to authenticate with a username and password.

Multi-factor authentication actions

The flow endpoint can also initiate multi-factor authentication (MFA) actions that specify the operations required to complete authentication using a registered user device and a one-time password (OTP).

Identity first actions

The flow can initiate a discovery action used to identify the user by username and determine the applicable authentication methods for this user.

Progressive profiling actions

Progressive profiling actions prompt users to provide additional data at sign on. This action type does not authenticate users. It is used only to obtain additional profile data.

Agreement actions

Agreement actions enforce user consent to an agreement at sign on. This action type does not authenticate users. It is used only to obtain user consent to a terms of service agreement.

Identity provider actions

An action that bypasses the PingOne sign-on prompt and immediately redirects the user to an external identity provider’s sign-on workflow to authenticate.

Use Cases

Flow status

In a sign-on workflow, the flow’s status property value returned by the last action identifies the appropriate next action in the authentication process. For example, if an application uses the LOGIN sign-on policy, when a user initiates sign-on and starts the authentication flow, the response returned by the flow shows a status value that specifies the next required step to complete this flow successfully. For the LOGIN sign-on policy, the next action prompts the user to enter a username and password, as indicated by the USERNAME_PASSWORD_REQUIRED value in the status property.

"status" : "USERNAME_PASSWORD_REQUIRED"

The response data includes a link to the required action, which in this case is the usernamePassword.check:

{
  "_links" : {
    "self" : {
      "href" : "https://auth.pingone.com/{{envID}}/flows/{{flowID}}"
    },
    "session.reset" : {
      "href" : "https://auth.pingone.com/{{envID}}/flows/{{flowID}}"
    },
    "usernamePassword.check" : {
      "href" : "https://auth.pingone.com/{{envID}}/flows/{{flowID}}"
    }
  },

After the user submits a username and password, the flow calls the usernamePassword.check action to verify the username and password.

For more information about flow actions, see Flow API Actions.

Flow status values

An authentication flow can return one of the following status values in response to a sign-on action:

Status value Description
USERNAME_PASSWORD_REQUIRED This value specifies that a username and password is required. This status can initiate a usernamePassword.check action, a user.register action, a registration.external action, a password.forgot action, or an authenticate action to sign on using an external identity provider.
PASSWORD_REQUIRED This value specifies that a password is required. This status initiates a usernamePassword.check action.
SIGN_ON_REQUIRED This value specifies that a sign-on action is required. This status transitions to a user.lookup action and a registration.external action in a passwordless authentication flow.
RECOVERY_CODE_REQUIRED This value specifies that the user initiated a password.forgot action and a recovery code must be sent. This status calls the password.recover action.
VERIFICATION_REQUIRED This value specifies that the user’s account must be verified. This status calls the user.verify action.
OTP_REQUIRED This value specifies that the user must complete a multi-factor authentication action. This status calls the otp.check action.
DEVICE_SELECTION_REQUIRED This value specifies that the user must complete a device selection multi-factor authentication action. This status calls the device.select action.
PASSWORD_EXPIRED This value specifies that a user’s password has expired and must be updated. This status calls the password.reset action.
MUST_CHANGE_PASSWORD This value specifies that a temporary password must be changed or updated. This status calls the password.reset action.
ACCOUNT_LINKING_REQUIRED This value specifies that the external identity returned by the identity provider requires an account linking action to link the external account to an existing user. This status can initiate a usernamePassword.check to link to an existing user, a user.register action to create a link to a new user, a registration.external action, or a password.forgot to link to an existing user who has forgotten the password.
ACCOUNT_CONFIRMATION_REQUIRED This value specifies that the external identity informaiton returned by the identity provider requires an account confirmation action to verify the account data. This status can initiate a user.confirm action to verify the account information.
EXTERNAL_AUTHENTICATION_REQUIRED This value specifies that account authentication is required through an external identity provider’s authentication flow. The authenticate embedded resource link provides the location to redirect the browser to sign on with the specified identity provider.
PROFILE_DATA_REQUIRED This value specifies that user must submit the requested profile data in order to continue the authentication flow.
COMPLETED This value specifies that the entire flow is completed and initiates a browser redirect to the resumeUrl property to continue.
FAILED This value specifies that the entire flow has failed.
PUSH_CONFIRMATION_REQUIRED This value specifies that a push was sent to a native device to confirm the authentication. The client will have to poll this status using GET /{{envID}}/flows/{{flowID}} to check whether the native device answered the push.
PUSH_CONFIRMATION_TIMED_OUT This value specifies that a push was sent to a native device, but the native device didn’t answer the push during the allowed timeframe.
ASSERTION_REQUIRED This value specifies that for a FIDO2 device type, an assertion generated by the browser from the provided webauthn public key credential request is required to continue the flow. The flow calls the assertion.check action.
AGREEMENT_CONSENT_REQUIRED This value specifies that users need to consent to an agreement. This status calls the user.consent action.
DAG_USER_CODE_REQUIRED This value specifies that an activation action is required to continue the flow. The flow calls the deviceAuthGrant.userCode.verify action.
DAG_CONSENT_REQUIRED This value specifies that users need to consent to a device authorization grant agreement. This status calls the deviceAuthGrant.consent action. After accepting consent, a record is stored in the user’s OAuth Scope Consents.
COMPLETED_ACCEPTED This completed state is used for device authorization grants to transition to a completed state. Unlike the COMPLETED flow state, this state does not transition the flow to the resume URL.
COMPLETED_DECLINED This completed state is used for device authorization grants to transition to a completed state, and it generates a “device consent declined” audit event.
