Identity Verification — When adding a new user, the user will be automatically authenticated for their current browser session and you do not need to call the authenticateUser function or provide a signature to subsequent API requests.

Identity Verification — A HTTP 403: Forbidden error will be returned if the following conditions are met: (1) the project has identity verification enabled, (2) the given email address already exists in the project, and (3) there is no authentication cookie present on the user's browser (e.g. you have not called the authenticateUser function).

Pro Tip — Use the recordFormImpression function when using your own form in order to ensure the form impression and signup conversion rate data is accurate on your Analytics Dashboard.

Authenticate a User

If your project has identity verification enabled, you can authenticate the user into their current browser session so that you do not have to provide a signature to each subsequent API request. This authentication will last until the user closes their browser.

Note — When adding a new user, the user will be automatically authenticated for their current browser session and you do not need to call this function nor provide a signature to subsequent API requests. 

    
      prefinery('authenticateUser', data, callback);

Parameters

data string or object
required An Object, where keys can be:
  • email or referral_code or id— Either the user's email address, referral code or id.
  • signature— HMAC signature of the email, referral_code, or id value and your project's identity verification secret. Learn more about identity verification.
callback function
optional A callback function that will be invoked after the user is authenticated.

Example Requests

    
      prefinery('authenticateUser', {
        email: 'leonard@bigbangtheory.com',
        signature: 'd181b885962e4c8aad0fb4d241e018b67f59e579c475bb4a454c743688237503'
      }, function() {
        // Do something, such as make one of the following API calls ...
      });

Note — A HTTP 401: Unauthorized error will be returned if the signature is incorrect.

Trigger Rewards

Evaluate a custom event and create all necessary rewards.

When you set up a reward in your Prefinery dashboard, you can specify that the reward be earned when a person completes a goal-based action (see What Triggers a Reward? for more information). This API method allows you to let us know that a person has completed an action. If having performed that action causes any rewards to be earned by any users, then those rewards will be created and the list will be returned here. 

    
      prefinery('triggerRewards', data, callback);

Parameters

data object
required An Object containing the email address of the user who performed a custom event and the name of the custom event performed.
  • email — The person’s email address.
  • signature— HMAC signature of the email address and your project's identity verification secret. Required if there is no authentication cookie present on the user's browser and you have identity verification enabled.
  • event — The name of the custom event the user performed.
callback function
optional A callback function that will be invoked with an array of any triggered rewards.

      });

      prefinery('recordFormImpression', function() {
        // Do something ...

      prefinery('initForms');

Logout User

optional A callback function that will be invoked when the user has been logged out and their authentication cookie is removed.

Example Requests

    
      // Without callback
      prefinery('logoutUser');
    
  
    
      // With callback
      prefinery('logoutUser', function() {
        // Do something ...
      });
