Understanding Lending APIs

Counting the zeros? Let’s simplify it.

INR 47.4 Lakh crore

That is the total value of loans in digital lending, estimated to be disbursed by 2026!

A huge amount, right?

As evidenced by this, the digital lending industry in India is on an uptrend and doesn’t seem to be ending soon. Countless financial products and services are popping up daily to facilitate this large quantity of loan disbursements, small or huge, to happen every day. These digital systems should seamlessly disburse loans and ensure there is no room for crimes like data breaches, phishing scams, loan stacking, etc.

So how is this done?

Using the Application Programming Interface (API). This collects customer KYC (Know Your Customer) details, verifies the documents, credit bureau reports, analyzes their bank statements, and sets up e-Nach for automated payments and loan disbursal. 

In this blog, we will explore APIs and why it is a good idea to API-fy your lending business.

So, what are APIs?

APIs are a series of protocols that allow a software solution to call on functions from other sources and systems. APIs help lenders acquire critical information for loan origination and management system decisions.

APIs help Financial institutions to streamline digital onboarding processes by automating data collection. It also helps to integrate with external systems such as payment gateways and credit bureaus. This helps in gathering customer details and speeds up the approval process by reducing manual intervention.

API helps to improve operational efficiency by ensuring that customers are onboarded quickly with minimal delays while at the same time maintaining compliance with regulatory standards.

Where do APIs fit in the lending sector?

API connects different systems in a lending ecosystem and shares information required for borrowers’ evaluation & loan disbursal.

Imagine this. You are a key decision-maker in a microfinance company that offers loans to small businesses. A grocery store owner who dreams of expanding his business approaches you to avail loan, as this is the best time for them to buy inventory at a discounted rate. They need the loan quickly to utilize the opportunity.

As a lender, you are responsible to:

  • Authenticate customer identity by performing KYC
  • Check if they have optimal cash flow by analyzing bank statements 
  • Verify income details and check if they pay taxes regularly
  • Perform credit check and assess repayment potential based on past loans if any

The problem? All these should happen blazing fast. If not, the customer is going to find another lender.

So what would you do in such a situation? Collect all documents, manually verify them with relevant sources, and let the customer know your decision—quite laborious, right?
 

Here’s where API can make all the difference

API helps to automate the entire workflow. You can instantly connect to government databases, Income tax portals or credit bureaus and verify what you want.

For example, to check the customer’s PAN validity, simply enter the PAN number and the API fetches you all the information related to the customer’s PAN and income tax details with just a few clicks. 

API is that powerful! 

API-fication for Lending Businesses – What are the real benefits?

According to API Performance Stats, APIs’ average response time is as low as 339 milliseconds. This allows businesses to analyse, approve, and process loan requests almost instantly.

The following are some of the ways API benefits lending businesses:

  • Automates borrower verification and performs data checks in the loan origination system, thus significantly speeding up the loan approval process.
  • Improves customer satisfaction by enabling faster credit checks and real-time loan decisions.
