This article will introduce how to use Azure Notification Hub REST API to send a notification to device with Baidu Push. It provides an example of how to retrieve the PNS handle and send notification to device using REST API with Baidu Push.

Pre-requirement :

Before starting, you must setup a Baidu Push environment and create a application in Android Studio.

• Download Baidu Push Android SDK


• Create a Baidu Push account and create application : Getting Started with Baidu Push (baidu.com)


• Create an application in Android Studio : Connect your app to the notification hub | Microsoft Docs

Getting started with Azure Notification Hub using Baidu

1. Enter API Key and SECRET KEY in Azure Portal -> Notification Hub -> Baidu (Android China).
   
   Note : Go to the Configuration page of the Baidu Push application and you can find API KEY and SECRET KEY.
   


2. Execute your application in Android Studio and you should see below keywords in.
   errorCode=0 : 0 means the device is registered successfully via Baidu SDK.
   userId : copy this for next step

3. Create a registration for the device. This method generates a registration ID, which you can subsequently use to retrieve, update, and delete this registration.
