जावा के साथ व्हाट्सएप एपीआई कैसे भेजें

परिचय

इस ट्यूटोरियल में, हम जावा का उपयोग करके व्हाट्सएप एपीआई के माध्यम से संदेश भेजने के लिए सरल उदाहरण बनाएंगे।

प्रारंभ में, आपको यह सुनिश्चित करना होगा कि okhttp3 पुस्तकालय तैयार है क्योंकि हम इस पुस्तकालय का उपयोग इस लेख में Ultramsg Gateway पर संदेश भेजने के लिए करेंगे।

जावा का उपयोग करने वाला पहला व्हाट्सएप एपीआई संदेश

package com.mycompany.mavenproject1;
import java.io.IOException;
import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

}

जब पिछला कोड निष्पादित होता है, और यदि संदेश सफलतापूर्वक भेजा जाता है, तो प्रतिक्रिया इस प्रकार होगी:

{"sent":"true","message":"ok","id":43007}
