摘要：快遞查詢(xún)接口通用是給發(fā)貨電商用來(lái)實(shí)現(xiàn)查詢(xún)快遞物流軌跡功能的，接口對(duì)接前要先到快遞鳥(niǎo)網(wǎng)站申請(qǐng)接口秘鑰和對(duì)接要求查詢(xún)接口支持按照運(yùn)單號(hào)查詢(xún)單個(gè)查詢(xún)，并發(fā)不超過(guò)個(gè)。

快遞查詢(xún)接口通用API是給發(fā)貨電商用來(lái)實(shí)現(xiàn)查詢(xún)快遞物流軌跡功能的，接口對(duì)接前要先到快遞鳥(niǎo)網(wǎng)站申請(qǐng)接口秘鑰和APIKEY

對(duì)接要求：
(1)、查詢(xún)接口支持按照運(yùn)單號(hào)查詢(xún)(單個(gè)查詢(xún)，并發(fā)不超過(guò)10個(gè)/S)。
(2)、指定的物流運(yùn)單號(hào)選擇相應(yīng)的快遞公司編碼，格式不對(duì)或則編碼錯(cuò)誤都會(huì)返失敗的信息。如EMS物流單號(hào)應(yīng)選擇快遞公司編碼（EMS）
(3)、返回的物流跟蹤信息按照發(fā)生的時(shí)間升序排列。
(4)、接口指令1002
(5)、接口提供：快遞鳥(niǎo)
(6)、請(qǐng)求地址：http://api.kdniao.cc/Ebusines...
