Pre-Approvals

​

Prerequisites

Before diving into the integration process, ensure you have the following:

1. Sign up for a Drivly account
2. Create a DRIVLY_API_KEY
3. Have a basic understanding of REST APIs
4. A secure environment for handling sensitive data
5. Install the Drivly SDK

​

Overview

The concept of pre-approvals is to allow a user to get pre-approved for a loan before they start shopping for a car. This allows the user to know how much they can afford and what their interest rate will be. This is a great way to get users to commit to a purchase.

To complete this scenario, you will need to:

1. Install Dependencies
2. Create a Schema
3. Setup the SDK
4. Create a Pre-Approval
5. (Bonus) Update a Pre-Approval

​

Install Dependencies

This guide uses some other dependencies along with the Drivly SDK. Let’s install those dependencies.

​

Create a Schema

Next, we will use Zod to create a schema for the Pre-Approval. This schema will be used to validate the form data before we send it to the server.

​

Setup the SDK

Let’s create a singleton instance of the SDK and export it for use in our application. We will use the DRIVLY_API_KEY and will start in sandbox.

import { SDK } from '@drivly/commerce'

export const sdk = SDK({
  apiKey: process.env.DRIVLY_API_KEY as string,
  environment: 'sandbox',
})

​

Create a Pre-Approval

Now that we have the schema and the SDK setup, we can create the form that will be used to collect Danny’s information. We will use react-hook-form to handle the form state and @hookform/resolvers to use the Zod schema to validate the form data.

import { PreApprovalSchema } from './PreApprovalSchema'
import { zodResolver } from '@hookform/resolvers/zod'
import { useForm } from 'react-hook-form'
import { createPreApproval } from './preapproval.action' // server action

export default function PreApprovalForm() {
  const form = useForm<PreApprovalSchema>({
    resolver: zodResolver(PreApprovalSchema),
    defaultValues: {
      firstName: '',
      middleInitial: '',
      lastName: '',
      suffix: undefined,
      email: '',
      phone: '',
      address: '',
      city: '',
      state: '',
      zip: '',
    },
  })

  const onSubmit = async (data: PreApprovalSchema) => {
    const result = await createPreApproval(data)
    console.log(result.message)
  }

  return <form onSubmit={form.handleSubmit(onSubmit)}>{/* ... */}</form>
}

We will use Server Actions for this example.

Let’s create a server action that uses the SDK to create Danny’s pre-approval.

'use server'

import { PreApproval } from '@drivly/commerce'
import { sdk } from './sdk'

export const createPreApproval = async (
  data: Omit<PreApproval, 'id' | 'createdAt' | 'updatedAt'>
) => {
  try {
    const result = await sdk?.commerce.preApprovals.create({ doc: data })
    console.log('Pre-approval created:', result)
  } catch (error) {
    console.error(error)
  }
}

​

Update a Pre-Approval

If we need to update or add information to their pre-approval, we can use the updatePreApproval action.

​

Conclusion

Danny can now fill out the form and get pre-approved for a loan. We can then use the preApprovalId to access his pre-approval. This will allow you to show him cars that he can afford and give him an idea of what his interest rate will be.
