Link APIs

Overview

This API has been available since 1.28.0

This page contains the APIs that are used to manage Links that establish a relationship between a FusionAuth User and an Identity Provider.

This API is used to create a link between a FusionAuth User and a user in a 3rd party identity provider. This API may be useful when you already know the unique Id of a user in a 3rd party identity provider and the corresponding FusionAuth User.

Request

This API has been available since 1.43.0

Link a User
POST/api/identity-provider/link

Request Headers

X-FusionAuth-TenantId[String]optional

The unique Id of the tenant used to scope this API request.

The tenant Id is not required on this request even when more than one tenant has been configured because the tenant can be identified based upon the request parameters or it is otherwise not required.

Specify a tenant Id on this request when you want to ensure the request is scoped to a specific tenant. The tenant Id may be provided through this header or by using a tenant locked API key to achieve the same result.

See Making an API request using a Tenant Id for additional information.

Request Body

identityProviderLink.displayName[String]optional

A optional human readable name for this link such as an email address, username or given name. This value should be used to make it easier to identify the user this link represents in the remote identity provider.

Please note, that this value will always be overwritten during login to reflect the most current information from the identity provider. In most cases this value will be an email address or username.

identityProviderLink.identityProviderId[UUID]required

The Id of the identify provider that will be linked to the User.

identityProviderLink.identityProviderUserId[String]required

The Id for the user that is provided by the upstream identity provider. This is the value that will allow FusionAuth to link this User on future logins. This value is expected to be immutable.

identityProviderLink.userId[UUID]required

The unique Id of the FusionAuth User that is being linked to the identity provider.

identityProviderLink.token[String]optional

The token returned from the identity provider. This is treated as an opaque token as the type varies by identity provider, this value may not be returned by all identity providers. When provided, this token is typically a long lived access or refresh token, but consult individual identity provider documentation for specifics.

This API has been available since 1.46.0

This API is used to retrieve a pending IdP Link. A pending IdP Link is created after a user completes login with an Identity Provider configured with a linking strategy of Create a Pending Link . This pending IdP link is then used to link a user in a 3rd party identity provider to a user in FusionAuth.

Retrieving this link may be useful if you are building your own login pages, and need to identify the Identity Provider or various meta-data associated with his pending link.

Request

Request Headers

X-FusionAuth-TenantId[String]optional

The unique Id of the tenant used to scope this API request.

The tenant Id is not required on this request even when more than one tenant has been configured because the tenant can be identified based upon the request parameters or it is otherwise not required.

Specify a tenant Id on this request when you want to ensure the request is scoped to a specific tenant. The tenant Id may be provided through this header or by using a tenant locked API key to achieve the same result.

See Making an API request using a Tenant Id for additional information.
