Get 2B Data API
Retrieve GSTR-2B ITC and reversal document details by GSTIN and return period, for accurate input tax credit computation and GST reconciliation.
What the Get 2B Data API does
Get 2B Data returns GSTR-2B ITC reversal details for a GSTIN and return period. GSTR-2B is the static monthly statement used to determine eligible input tax credit.
Because 2B is fixed for the period rather than updating continuously, it is what most businesses reconcile against. The reversal details matter because credit claimed and later reversed still affects the final position.

Frequently Asked Questions (FAQs)
Why use 2B rather than 2A?
2B is static for the period, so reconciliation against it is reproducible. 2A keeps changing as suppliers file.
What is an ITC reversal?
Credit previously claimed that must be reversed under the GST rules, which changes the net position for the period.
How often should I reconcile?
Monthly, aligned to the return cycle, so problems surface while there is still time to act.
