Get Issuing Bank Down BINs API

The Getting Issuing Bank Down Bins API (gettingIssuingBankDownBins) is used to retrieve the card BINs for all the banks that are observing either full downtime or partial downtime at an instance.

Response parameters

The API returns a JSON array. Each object describes one issuing bank and the BINs that are down (full or partial downtime per your var2 filter). If var1 is default, you get entries for all applicable banks; if var1 is a specific bank code, the response is scoped to that bank.

Parameter/JSON field	Description	Example
issuing_bank	Issuing bank code for this entry.	ALLBD
status	Status code for this bank’s downtime entry (as returned by PayU).	2
title	Display name of the issuing bank.	ALLAHABAD BANK
bins_arr	List of card BINs under this bank that are in downtime (full or partial, per var2).	["421337", "608219", …]

Request parameters

Use the following sample values while trying out the API:

Reference information for request parameters

Parameter	Reference
key	For more information on how to generate the Key and Salt, refer to any of the following: Production: Generate Merchant Key and Salt Test: Generate Test Merchant Key and Salt
command	Must be getIssuingBankDownBins.
var1	Bank name code (as provided by PayU) or default for all banks.
var2	0 — BINs that are fully down; 1 — BINs that are partially down.
hash	Hash logic for this API is: `sha512(key\|command\|var1\|salt) sha512`

Example values:

var1: Pass default for downtime across all banks, or a specific bank code (e.g. ALLBD) for one bank.
var2: 0 for fully down BINs, 1 for partially down BINs (see sample request).
