# Impersonate a user

This example shows you how to create a Smart Action `"Impersonate"` to login as one of your customers.

It can be useful to help your customers debug an issue or to get a better understanding of what they see on their account (in your app).

## Requirements

* An admin backend running on forest-express-sequelize/forest-express-mongoose

## How it works

### Directory: /models

This directory contains the `users.js` file where the model is declared.

<Tabs>
  <Tab title="SQL">
    ```javascript theme={null}
    module.exports = (sequelize, DataTypes) => {
      const { Sequelize } = sequelize;
      const Users = sequelize.define('users', {
        email: {
          type: DataTypes.STRING,
        },
        createdAt: {
          type: DataTypes.DATE,
        },
        //...
      }, {
        tableName: 'users',
        timestamps: false,
        schema: process.env.DATABASE_SCHEMA,
      });
    ​
      Users.associate = (models) => {
      };
    ​
      return Users;
    };
    ```
  </Tab>

  <Tab title="Mongoose">
    ```javascript theme={null}
    const mongoose = require('mongoose');

    const schema = mongoose.Schema({
      'email': String,
      'createdAt': Date,
      ...
    }, {
      timestamps: false,
    });

    module.exports = mongoose.model('users', schema, 'users');
    ```
  </Tab>
</Tabs>

### **Directory: /forest**

This directory contains the `users.js` file where the Smart Action `Impersonate`is declared.

<Tabs>
  <Tab title="SQL">
    ```javascript theme={null}
    const { collection } = require('forest-express-sequelize');

    collection('users', {
      actions: [
        {
          name: 'Impersonate',
          type: 'single',
        },
      ],
    });
    ```
  </Tab>

  <Tab title="Mongoose">
    ```javascript theme={null}
    const { collection } = require('forest-express-mongoose');

    collection('users', {
      actions: [
        {
          name: 'Impersonate',
          type: 'single',
        },
      ],
    });
    ```
  </Tab>
</Tabs>

### **Directory: /routes**

This directory contains the `users.js` file where the implementation of the route is handled. The `POST /forest/actions/impersonate` API call is triggered when you click on the Smart Action in the Forest UI.&#x20;

  <Tab title="SQL">
    ```javascript theme={null}
    router.post('/actions/impersonate',
      (req, res) => {

    ​
        response.send({

            url: 'https://my-app-url/login', // The url of the company providing the service.
            method: 'POST', // The method you would like to use (typically a POST).
