Consumer Splitpay

Introduction

This guide explains the integration process of Solaris' Splitpay product for retail customers (Consumers) as a standalone solution, including the mandatory information you must collect from your customers and the necessary endpoints and webhooks you must integrate into your solution.

Product specifications

Consumer Splitpay are currently only available for customers in Germany with a German bank account. Check the overview page for more details on the product specifications.

Credit scoring

Solaris uses an automated credit scoring system (Splitpay scorer) to make informed credit decisions on consumer credit line applications. The scorer collects and analyzes different information, such as the customer's self-declared 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 a credit line and the limit to be granted.

How does the scorer interact with the consumer credit line service?

The consumer credit line service and its related endpoints handle consumer credit line requests and collect the required information about the applicants, such as self-declared financial information, credit records, and account snapshots. Throughout the lifecycle of a consumer credit line application, the scorer provides different responses based on the information provided during each stage of the application.

The scorer performs different credit checks throughout the application lifecycle, such as:

  • Initial scoring: In this stage, the scorer evaluates the self-declared information the applicant provided in the credit line application and the credit record obtained from external credit bureaus, such as SCHUFA. Based on this information, the scorer gives decision either to offer a credit line right away or to require a verification step through an account snapshot.
  • Verification: The scorer uses the account snapshot to verify the financial information provided in the credit line application. This is the final check, after which the scorer provides the final decision.

System prerequisites

Before integrating Solaris' Consumer Splitpay, implement the following requirements:

1. Technical setup:

Set up your environment and get your authentication keys. For step-by-step instructions, check the Technical setup guide.

2. Legal and compliance screens:

Build the necessary legal and compliance screens in your sign-up flow to collect your customers' consent to the necessary legal and compliance requirements. The Legal and compliance screens guide contains step-by-step instructions on how to create these screens and what they must contain.

The following screens are required to onboard B2C customers for lending standalone products:

  1. Terms and Conditions
  2. Customer information
  3. Economic interest

Record the customer's consent on each screen as a UTC timestamp (e.g., 2019-01-01T00:00:00Z). Afterward, you must pass each timestamp in its respective field to Solaris.

  • Collect the customer's consent to Solaris's Terms and Conditions and store the timestamp in the terms_conditions_signed_at field.
  • Collect the customer's consent to data processing and store the timestamp in the data_terms_signed_at field.
  • Collect the customer's economic interest declaration and store the timestamp in the own_economic_interest_signed_at field.
note

The mentioned fields are part of the person resource in which all the customer data points are stored.


Integration overview

Important
  • This guide includes the integration process for Consumer Splitpay as a standalone solution, i.e., the credit limit will be added to an external account.
  • For existing customers who already have a current account with Solaris and wish to apply for a credit line, skip Step 2.

Integrate Solaris' Consumer Splitpay by completing the following steps:

Stage Step Description
Customer registration Step 1 - Optional Generate an anonymous installment plan for a given amount for the customer.
Customer registration Step 2 Collect the mandatory customer data and consent to the legal and regulatory requirements in your sign-up flow, and create a person resource for your customer.
Credit line application Step 3 Create a credit record for the customer.
Credit line application Step 4 Create a credit line application for the customer and include all mandatory data points required for the scorer.
Credit line application Step 5 - Optional Create an account snapshot for the customer and link it to the credit line application.
Customer identification & contract signing Step 6 Send the customer the SECCI form and the credit line final contract.
Customer identification & contract signing Step 7 Trigger the KYC and e-signing flow for the customer, and redirect the customer to complete the identification process with IDnow and sign the relevant contracts. Ensure that the customer is successfully identified and passes the risk screening before proceeding with the following steps.
Credit line usage & servicing Step 8 Whenever a customer uses an amount from the credit line limit, an installment loan for this amount will be created and serviced separately, and the remaining amount of the credit line limit will be recalculated. Implement all the relevant endpoints in this step.

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

Step 3: Create credit record

In this step, you must 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 4: Create consumer credit line application

After collecting the mandatory personal information from the customer and creating a person resource, you must collect additional information from the customer related to the credit line application, and pass them to Solaris using the following endpoint:

POST Create consumer credit line application

Call this endpoint to create a consumer credit line application for your customer. You must add the following mandatory properties in the request body, which the credit scorer uses to initiate a series of credit checks:

Mandatory properties:

  • requested_credit_limit
  • credit_record_id
  • employment_since
  • living_situation
  • living_situation_amount
  • existing_credit_repayment_excluding_mortgage
  • marriage_status
  • moved_in_last_two_years
  • net_income_amount
  • number_of_dependents
  • private_insurance_amount
  • recipient_iban
  • repayment_day_of_month

The application status changes to initial_scoring_pending after calling this endpoint.

Request URL

Copy
Copied
POST /v1/persons/{person_id}/credit_line_applications

Click here to view the full API reference

Scoring results:

This API call triggers the credit scoring system, which initiates the initial scoring based on the self-declared information passed in the payload and the credit record, and rejects applications that don't meet the minimum credit eligibility criteria.

Approved application

  • If the application passes the initial scoring and no account snapshot or identification is needed, then the application status goes directly to offered. In this case, proceed to step 6 to generate the relevant contracts for the customer.
  • Alternatively, the status can go to account_snapshot_verification_pending if an account snapshot is required. In this case, complete step 5 to create an account snapshot and link it to the application.

Rejected application

If the application is rejected, the application status changes to rejected, and you must abort the customer onboarding process.

GET Retrieve consumer credit line application

This endpoint returns the current status and details of an existing consumer credit line application. For a list of possible values of the application status and their descriptions, check the appendix.

Additionally, subscribe to the webhook event CREDIT_LINE_APPLICATION to receive status updates on the application.

Application status flow

The following diagram describes the status flow of a consumer credit line application:

Diagram: Consumer credit line application flow


Step 5: Create account snapshot and link it to the application (Optional)

If the application status changes to account_snapshot_pending, then the final verification step is required to complete the credit scoring process. In this case, you need to create an account snapshot for the customer and link it to their credit line application by calling the following endpoints:

What is an account snapshot?

The account snapshot contains a breakdown of the customer's account information, such as balance, transactions, bookings, and recurrent repayment amounts over a certain period of time. Creating an account snapshot is usually required in lending products integrations as it's used for credit scoring to verify the customer's financial data.

Integrate the following endpoints to create account snapshots for your customers.

API reference

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

POST Create an account snapshot for a customer

Step 6: Send SECCI form and credit line contract

Before prompting the customer to sign the final contract of the credit line, you must send the customer the Standard European Consumer Credit Information (SECCI) form. The SECCI form is a standardized credit form that includes the information related to a credit offer, such as creditor details, type of credit, amount, duration, interest rates, credit costs, etc.

In compliance with regulatory requirements, you must first send the customer the SECCI form to review and approve. Afterward, you can send them the final contract which they have to sign during the identification and e-signing process.

Implement the following endpoints to generate the SECCI form and final contract of a credit line:

GET Retrieve the SECCI form of a credit line

Call this endpoint to generate the SECCI form of the credit line as a PDF. You must share this form to the customer before sending the final contract either via email or direct download through your app.

Request URL

attention

The customer must also sign an SDD mandate, which authorizes Solaris to debit the customer's account for the monthly installments. For more information about SDD mandates, check the SEPA DIRECT DEBIT GUIDE.


Step 7: Complete the customer identification and e-signing process

In the step, you must prompt the customer to complete the identification process, in which the customer will be identified in a video identification session through our provider IDnow. During this session, an identification agent will verify the customer's data against their identification documents, verify their mobile number, and collect the customer's qualified electronic signature (QES) on the credit line contract, SDD mandate, and terms and conditions.

Call the following endpoints once the status of the consumer credit line application changes to esign_pending.

info

This guide explains the integration process with video identification as the identification method. For an overview of other available KYC methods, check the customer KYC products overview page and consult with your Partner Manager.

GET Retrieve the signing ID

When the application status changes to esign_pending, it means that the identification and e-signing process has been triggered for the customer. You must call the GET Retrieve consumer credit line application method to get the signing_id, which you'll need to retrieve the identification details.

GET Retrieve e-signing and identification details

Once you obtain the signing_id from the previous endpoint, call the following method to get the video identification details, such as IDnow reference and URL.

Request URL

Copy

Identification and screening results

In this step, the customer will be identified through our KYC partner IDnow and internally screened by Solaris for risk metrics:

Successful identification:

Once the customer completes the identification and e-signing process successfully, the credit line application status changes to esign_complete.

Failed identification:

If the identification and e-signing process fails, the credit line application status changes to esign_failed. In this case, the customer can attempt to identify again depending on the reason for failure from IDnow.

Successful screening:

Once the application status reaches esign_complete, the screening process will be triggered. If successful, the status will change to credit_line_creation_pending triggering the final steps of the onboarding process, which is the credit line and account creation.

Failed screening:

If the screening process fails, the application status will change to rejected, and you must abort the onboarding process.

GET Retrieve the credit line ID

Once the customer completes the video identification and QES processes, Solaris creates the credit line. You can track the credit line creation process by calling the GET consumer credit line application method.

Once the credit line has been created, the application status changes to credit_line_created, and the credit_line_id will be included in the payload and the full credit line details such as the amount and interest rates.

Additionally, Solaris will create an account for the customer, which will be used in the scope of the credit line agreement. The account_id will also be included in the payload.


Step 8: Credit line usage and servicing

This step includes all the relevant endpoints you need to integrate into your solution to use and service credit lines.

Credit line usage

After a customer is granted a credit line, they can use the limit in the form of single installment loans.

For example, if Solrisbank offers a customer a 5,000 EURO credit line limit, they can choose to use 3,000 EURO to pay back the principal and interests in monthly installments over the course of 24 months. An installment loan for this amount and term will be created and serviced separately, leaving the customer with a remaining credit line limit of 2,000, which they can use in

note

A credit line must be created.

POST Generate available installment plans

Once a customer is granted a credit line, they can convert previous transactions into installments. You must generate possible installment plans and terms for the given amount and share them with the customer.

This endpoint generates possible installment plans for a given amount. The API call returns an array of possible installment plans for the given amount, including the term, monthly installment amount, and applicable interest rate.

Request example:

POST Create a credit line loan

This endpoint creates a loan resource based on an installment plan. The loan is used for bank statements and should shortly describe the purpose of the loan. Additionally, you should assign a reference for the loan and indicate whether a loan for a specific transaction was already created.

The API call returns an object with a unique ID, the loan_id, and the loan status.

For a list of possible values of the credit line loan status and their descriptions, check the appendices section. Additionally, subscribe to the webhook event LOAN to receive status updates about the loan.

Credit line account statements

Due to regulatory requirements, you need to generate annual account statements for credit lines for all of your customers with an active credit line. As long as the credit line remains active, you must share the annual statement with the customer every year as a PDF file, either via email or direct download through your frontend.

Additionally, in case of terminated credit lines, you need to generate a closing account statement and share it with the customer after the termination and account closure process has been completed.

GET Download annual account statement for a credit line

Call this endpoint to download an annual account statement for a credit line.

Click here to view the full API reference.

GET Download closing account statement for a credit line

Call this endpoint to download a closing account statement for a credit line.

Credit line termination

Credit lines can be terminated either by Solaris or by the customer.

The termination process is handled internally by Solaris and it depends on your specific configurations with Solaris. If your customer wants to terminate an existing credit line, contact your Partner Manager to receive more information about the process.


Account closure and Splitpay termination

If an account closure request is initiated for a customer's account, any associated credit line must also be terminated. Contact your Partner Manager to receive more information about the credit line termination process.

For more information about account closure requests, check the related Account Closure guide.


Credit line renewal (France only)

For customers in France, credit lines cannot be offered with an unlimited term. Credit lines are offered for a period of 12 months and must be explicitly renewed by the customer.

The process for credit lines renewals is as follows:

  • Solaris will notify you about the credit line renewal via the webhook event CREDIT_LINE.
  • You must notify the customer of the renewal request.
  • Call the endpoint PATCH Send confirmation to Solaris about customer renewal notification to inform Solaris that you've notified the customer, and include the notification date in the request body.
  • In case the customer doesn't want to renew the credit line, call the endpoint POST Cancel credit line renewal to initiate the termination process. Please note that all credit line obligations must be repaid before terminating the credit line and closing the account.
  • If the customer doesn't cancel the renewal, the credit line will be automatically renewed.
