Merging a guest session with a authenticated user

Frigade will generate a guest user ID for you if you do not provide a user id. This ID is stored in the user’s browser using localStorage. This allows unauthenticated users to have state in Frigade Flows and to be able to continue their session when they return to your application.

Often it is useful to link a guest session to a user when they register or log in and transfer all state and data.

You can do this by calling the Users API endpoint with a linkGuestId parameter. This will merge all state from the guest session to the user with the userId you provide. Note that this will only take affect if the given userId does not yet have any state in Frigade.

To do this in Javascript, you can use the fetch API:

const options = {
  method: 'POST',
  headers: { Authorization: 'Bearer <FRIGADE_PUBLIC_API_KEY>',
            'Content-Type': 'application/json' },
  body: '{"userId":"<USER_ID>", "linkGuestId":"<GUEST_ID>"}'
};

fetch('https://api.frigade.com/v1/public/users', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));
