Consumer Overdrafts

This guide explains how to integrate Solaris' Overdraft product for retail customers (Consumers) into your solution.

Introduction

Product specifications

Consumer overdrafts are currently only available for customers with a current bank account with Solaris. For more information about overdrafts and how they work, check the Overview page.

Credit scoring

Solaris uses an automated retail credit scoring system to make informed credit decisions on consumer overdraft applications. The scorer collects and analyzes different information, such as the customer's financial information, credit data, transaction history, and outstanding loans to assess their creditworthiness and determine their risk level and credit eligibility.

Based on different credit checks done throughout the application lifecycle, the scorer estimates the probability of default (PD) and then determines whether to offer an overdraft to the customer. It also determines the amount and interest rate to be granted.

Credit risk analysis

The scorer uses the following information in the credit risk analysis:

1. Account snapshot

Solaris collects information about the customer's account data and history from their current account with Solaris. Such information includes account balance, transaction history, bookings, and recurrent repayment amounts.

2. Information from credit agencies

Credit information and score about the customer, collected from external credit bureaus (e.g., SCHUFA).

note

Currently, external Credit Bureaus refer to SCHUFA. However, Solaris' scorer interface supports handling any number of external sources.


System prerequisites

Before integrating Solaris' Consumer overdrafts for your retail customers, the customers must have been onboarded and have a checking bank account with Solaris. For step-by-step instructions on person onboarding for Digital Banking and Cards, check the Person onboarding guide.


Integration overview

The following sequence diagram gives an overview of the integration flow for the Consumer Overdrafts solution:

Diagram: Consumer overdraft flow

Integrate Solaris' Consumer Overdrafts by completing the following steps:

Stage Step Description
Credit record Step 1 Collect the customer's consent to performing credit checks and create a credit record for the customer.
Overdraft application Step 2 Collect the required information from your customers on your frontend and create an overdraft application.
Overdraft documents Step 3 If the application is approved and the status changes to offered, download the SECCI form and the overdraft terms and conditions and share it with the customer as a PDF. Once reviewed by the customer, record the customer's consent to the terms and conditions and the overdraft loan agreement as a UTC timestamp.
Overdraft creation Step 4 Create the overdraft on the customer's account. Afterward, Solaris credits the overdraft limit to the customer's account as an external balance.
Overdraft servicing Step 5 Integrate all endpoints related to overdrafts servicing.

You can find detailed descriptions of these steps and their related endpoints in the following sections.

Webhooks

Solaris recommends subscribing to the following webhook events to better automate your processes. For detailed instructions on implementing Solaris webhooks, check the webhooks documentation.


Step 1: Create consumer credit record

In your frontend flow, collect the customer's consent to performing credit checks and account snapshot. Afterward, create a consumer credit record and link it to the person resource of the relevant customer.

What is a credit record?

The credit record contains the customer's credit data and history. Creating a credit record is usually required in lending products integrations as it's used for credit scoring to determine the customer's creditworthiness and eligibility.

Important
  • The credit record is only valid for onboardings in Germany since the information is retrieved from SCHUFA, which is a German credit bureau.
  • For lending onboardings in other countries, such as France, Italy, and Spain, creating a tax identification for the customer substitutes a credit record.

Integrate the following endpoints to create credit records for your retail customers.

API reference

Visit the following link to find all the endpoints related to the credit record resource, including related properties and examples.

To create a credit record for your customer, you can use one of the following endpoints depending on your customer type. You can create a credit record in two ways:

1. Via Solaris:

To create a credit record via Solaris, set the source field to solarisBank in the request body and Solaris will pull the customer's record directly from SCHUFA.

2. Manual upload:

In this case, you will collect the credit record manually through SCHUFA and/or other third-party service providers and upload the file to Solaris. Set the source field to partner and include the file content in the file field (Base64-encoded).

Step 5: Servicing overdrafts

This section includes important information about handling and monitoring active overdrafts.

Overdrafts limits and interest

Overdraft limits cannot be exceeded for any SEPA transfers, direct debits, payments, or withdrawals, except for charged interest fees by Solaris. Any payment exceeding the limit will be rejected.


Overdrafts monitoring (Optional)

For specific overdraft-related events, you can monitor the account, implement specific event triggers, and provide pre-defined messages to the user.

For example, you can implement event triggers and send out reminders to customers in the following events:

  • The customer has used 90% of the overdraft limit or only 100€ remaining in the limit.
  • Three days before the interest payment is due to customers with a used overdraft at the end of each quarter.

Overdrafts booking types

Using the overdraft limit reflects on the customer's account statement for interest charges. The following booking types are distinct to overdraft interest charges:

  • InterestOverdraft: The interest accrued in relation to the used portion of the overdraft limit.
  • InterestOverdraftExceeded: The interest accrued in relation to exceeding the overdraft limit (Note that the limit itself cannot be exceeded for regular transactions except for interest charges).

Account closure for accounts with an overdraft

In case of Account Closure Requests (ACR) for accounts with an attached overdraft, you must first terminate the overdraft before initiating the ACR process.


Overdrafts in statements of account & bank statements

Each statement of account and bank statement generated for customers with overdrafts will contain the following overdraft information for the statement period:

  • overdraft_facility: Overdraft facility that has been granted to the customer.
  • overdraft_rate: The increased interest rate applied when going below the granted overdraft facility.
  • interest_accrual_rate: The daily rate at which interest is accrued on the used amount of an overdraft.
  • interest_accrued: The interest accrued, in Euro cents.

See the Account management guide for more information.


Consumer overdraft limit changes

You can request an overdraft limit change either an increase or a decrease of limit by using the following endpoints. Solaris will assess the request and either approve it or reject it.

The following diagram shows the process flow of an overdraft limit change request:

Diagram: Consumer overdraft limit change flow

POST Request overdraft limit change

Consumer overdrafts termination

To terminate a consumer overdraft, you can trigger the termination request by calling the following endpoint:

POST Terminate a consumer overdraft

This endpoint initiates a termination request for an existing consumer overdraft.

Copy
Copied
POST /v1/persons/{person_id}/consumer_overdrafts/{overdraft_id}/terminate

Click here to view the full API reference

attention
  • Solaris performs certain validations on termination requests using this endpoint. The customer's account must be positive or zero after booking the accrued interest from the overdraft usage on the account.
  • If the account has negative balance, the request will be rejected. In this case, you can initiate a request to our support team by creating a JIRA ticket as explained in the previous section.
