Cómo enviar una API de WhatsApp con Objective-C

Introducción

En este tutorial, crearemos ejemplos simples para enviar mensajes a través de la API de WhatsApp utilizando Objective-C.

Primer mensaje de la API de WhatsApp usando Objective-C

#import <Foundation/Foundation.h>

NSDictionary *headers = @{ @"content-type": @"application/x-www-form-urlencoded" };

NSMutableData *postData = [[NSMutableData alloc] initWithData:[@"token=token_here" dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[@"&to=1408XXXXXXX" dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[@"&body=WhatsApp API on UltraMsg.com works good" dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[@"&priority=10" dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[@"&referenceId=" dataUsingEncoding:NSUTF8StringEncoding]];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://api.ultramsg.com/instance1150/messages/chat"]
                                                       cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                   timeoutInterval:10.0];
[request setHTTPMethod:@"POST"];
[request setAllHTTPHeaderFields:headers];
[request setHTTPBody:postData];

NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request
                                            completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
