High Value Loans

Interswitch Lending Services has integrated with data providers to enrich customer transaction information with bank statements currently provided by ILS to lenders. This will enable lenders provide high-value loans without the need for prospective customers having to provide physical documents like financial statements. The following are the features to be derived from this integration.

Please Note:

You need to have these endpoints defined on your application - Accept Offers, Get Offers, Get Loan Status, Payment Notification.

Step 1: Fetch the loan offer

Make a post request to the Get Offers endpoint to get a list of the available loan offers.

Request

curl --request GET \
     --url 'https://sandbox.interswitchng.com/lending-service/api/v3/offers?customerId=2348123456789&channelCode=QTUSSD&amount=5000000&serviceType=MONEY&dateOfBirth=1998-08-08&providerCode=MKT' \

Step 3 After confirming eligibility, you have two options:

  • Use the Send Offers endpoint if you want to respond to a customer's offer request later, especially when you need additional time to assess their credibility.
  • Alternatively, return an offer immediately using the Accept Offer endpoint if no additional time is required

}

Step 6: Inform the customer of the credit

After updating the loan status of the customer send a message using the send sms endpoint to the customer informing them of the credit. Sometimes, due to flaky internet connectivity or some other factors in which the credit process fails, you can perform a requery to confirm the status of the transaction.
