银行编码查询 · PAYJS API 开发文档

银行编码对应名称查询

根据银行简称查询银行详细名称。银行数据库会随时更新

请求参数：

字段名称	字段类型	必填参数	说明
mchid	string(32)	Y	商户号
bank	string(32)	Y	银行简写
sign	string(32)	Y	数据签名详见签名算法

请求返回：

字段名称	字段类型	必填参数	说明
return_code	int	Y	1:请求成功 0:请求失败
return_msg	string(32)	Y	返回消息
bank	string(32)	Y	银行名称
sign	string(32)	Y	数据签名详见签名算法

未查询到银行名称则返回 "not found"

该接口请求频率为50次/分

演示代码：

php python go

<?php
/**
 * 引入 payjs.class.php
 * https://github.com/payjs-cn/phpsdk
 */
include("payjs.class.php");

$mchid = '123456';
$key = 'xxxxxx';

$data = [
    "mchid" => $mchid,
    "bank" => 'XXX',
];

$payjs = new Payjs($mchid, $key);
$result = $payjs->bank($data);

print_r($result);

php

<?php

$payjs = new Payjs($mchid, $key);
$result = $payjs->bank($data);

print_r($result);
