Very likely you login every time you call send an SMS message, and the /auth endpoint has API call limit at 5 calls per 60 secs.
To avoid that, login once then call the SMS endpoint repeatedly. E.g.
var SDK = require('ringcentral')
var rcsdk = new SDK({
server: RINGCENTRAL_SERVER,
appKey: RINGCENTRAL_CLIENTID,
appSecret: RINGCENTRAL_CLIENTSECRET
});
var platform = rcsdk.platform();
platform.login({
username: RINGCENTRAL_USERNAME,
password: RINGCENTRAL_PASSWORD,
extension: RINGCENTRAL_EXTENSION
})
.then(function(resp) {
for (var i=0; i<40; i++)
send_sms()
});
function send_sms(){
platform.post('/account/~/extension/~/sms', {
from: {'phoneNumber': RINGCENTRAL_USERNAME},
to: [{'phoneNumber': "1234567890"}],
text: 'Hello World from Node JS'
})
.then(function (resp) {
var jsonObj = resp.response().headers
console.log(jsonObj['_headers']['x-rate-limit-limit'][0])
console.log(jsonObj['_headers']['x-rate-limit-remaining'][0])
console.log(resp.text())
console.log("SMS sent. Message status: " + resp.json().messageStatus)
})
.catch(function(e){
console.log(e.message)
});
}
More about API Rate Limit
It is not true that if you want to send more than 40 messages, you should use multiple numbers. Read this blog for detailed info.
