Step 18: Read External Authentication Initialization

GET {{authPath}}/{{destinationEnvID}}/rp/authenticate?providerId={{oidcProviderID}}&flowId={{flowID}}

When the option to sign-on with the identity provider is selected, the user is redirected to the external identity provider's sign-on screen to authenticate with a username and password:

Set the following parameters:

• providerId

Use the OIDC provider id.

• flowId

Use the flow id returned in the previous step.
