Method provides a script to seamlessly integrate Elements into your web application.

​
Installation

Include the initialization script into your application’s main html file.

<script src="https://static.methodfi.com/elements/v1/stable/init.js"></script>

​
Configuration

Once the initialization script has been included into your application, create an instance of the Method class.

const config = {
  env: 'production', // dev | sandbox | production
  onEvent: (event) => {
    // Invoked for every event triggerd by the element.
    // Event is a native MessageEvent instance.
  },
  onSuccess: (payload) => {
    // Invoked when an account has successfully been linked.
    // After accounts are linked, `payload.accounts` will contain a list
    // of public account tokens which you will be exchanged for an
    // account through the Method API.
  },
  onError: (error) => {
    // Invoked when an error is raised during.
  },
  onExit: (payload) => {
    // Invoked when a user exits any element flow, or
    // immediately after an error is raised.
  },
  onOpen : (payload) => {
    // Invoked when an element has successfully launched.
  },
};

const method = new Method(config);

Launch

​
Retrieve an element token

Before you can launch an element, you must first create an element_token for the element through the Method API.

In this example, we’re creating an element_token for the Connect Element.

See create an element token for more info.

​
Launch the element

Now that a Method instance and an element_token have been created, you can now launch the element.

method.open('pk_elem_BtzySdrQGFmLdAPw5gXSQNCxQkhCkT3K');
