# User invitation CTA

The API provides **Call to Action (CTA)** objects, which define the actions the current user is allowed to perform
on a specific user invitation.

Each CTA includes all the necessary argument values required to perform its respective action.
The purpose of the action is determined by the `actionId`.

## Available user invitation CTA types

* `ACCEPT_USER_INVITATION` - allows execution of [`acceptUserInvitation`](/OpignoEnterpriseAPI/UserConnection/AcceptDeclineUserInvitation#accept-invitation) mutation to add the invitation initiator to the current user's network.
* `DECLINE_USER_INVITATION` - indicates that [`declineUserInvitation`](/OpignoEnterpriseAPI/UserConnection/AcceptDeclineUserInvitation#decline-invitation) mutation can be executed.
* `CANCEL_USER_INVITATION` - represents that the current user can cancel the pending invitation by execution of [`cancelUserInvitation`](/OpignoEnterpriseAPI/UserConnection/AcceptDeclineUserInvitation#cancel-invitation) mutation.
