Sends an invitation to a project.

To add participants to a project, they must first be invited. Users that already exist in Kantata OX will automatically accept the invitation and be added to the project. If your account allows anyone to be invited to projects, users that don't already exist will have the option to create an account. Otherwise, the invited user must be a member of your account.

This endpoint has its own rate limit. See the Knowledge Base for more information.

This endpoint returns structured Workspace Invitation objects. As with all Kantata OX API endpoints, the returned data will be referenced in sorted order in the results array and will be indexed by ID in the workspace_invitations top-level JSON key. Please see our Response Format section for more information.
