## What the Get 2A Data API does

Get 2A Data returns the GSTR-2A B2B invoice details for a GSTIN and return period. GSTR-2A is the auto-populated statement of inward supplies, built from what your suppliers filed.

Reconciling purchases against 2A is how businesses protect their input tax credit. Where a supplier has not filed, the credit is at risk, and finding that early leaves time to chase them.

## Where teams use the Get 2A Data API

1.  Reconciling purchase records against supplier filings
    
2.  Identifying suppliers who have not filed
    
3.  Protecting input tax credit claims
    
4.  Automating monthly GST reconciliation
    

## Frequently Asked Questions (FAQs)

What is GSTR-2A?

An auto-populated statement of inward supplies, generated from the returns your suppliers filed.

How does it differ from 2B?

2A is dynamic and updates as suppliers file. 2B is a static monthly statement, which makes it the better basis for a fixed reconciliation.

What if an invoice is missing?

The supplier has probably not filed it. Your input tax credit on that invoice is at risk until they do.
