Has anyone built an integration with any SMS Receivers? - amazon-web-services

Question

I want to be able to send a text message to some number and then (upon receiving the text) basically just send a post request off to a different service after receiving the text. Does anyone know of a service I could use to set this up? Would like for it to be as fast as possible

Answer 1

Here's a summary of the steps to setup a sample app:
Navigate to Amazon SNS Service → Topics
Enter Name and create a new Topic
For the newly created topic, create a subscription where the Protocol is AWS Lambda (see image1 below)
Navigate to Amazon Pinpoint Service, create new Pinpoint application
Enable SMS & voice feature for this Pinpoint application
Get a new Long Code (long code price is $1/month)
For the long code, Enable two-way SMS, select the Choose an existing SNS topic option and select the SNS topic created in Step 2 above (see image2 below)
Finally, now you can send a message to that phone number from your phone and it will trigger your lambda function. In your lambda function, you can send a POST request to a different service or do whatever else. You can also respond back to the user's message - see example below.
Here's an example of how to send a message using Amazon Pinpoint in Java:
public void sendSMS(String pinpointPhoneNumber, String userPhoneNumber, String messageContent) {
// define who the message is going to and via what platform
Map<String, AddressConfiguration> addressMap = new HashMap<>();
addressMap.put(userPhoneNumber, new AddressConfiguration().withChannelType(ChannelType.SMS));
SMSMessage smsMessage = new SMSMessage();
smsMessage.setOriginationNumber(pinpointPhoneNumber);
smsMessage.setMessageType(MessageType.TRANSACTIONAL);
smsMessage.setBody(messageContent);
// add sms message to the direct message config
// this can have many other types of messages
DirectMessageConfiguration directMessageConfiguration = new DirectMessageConfiguration()
.withSMSMessage(smsMessage);
// put the phone numbers and all messages in here
MessageRequest messageRequest = new MessageRequest()
.withAddresses(addressMap)
.withMessageConfiguration(directMessageConfiguration);
// create send request
SendMessagesRequest sendMessagesRequest = new SendMessagesRequest()
.withApplicationId("put-pinpoint-app-id-here")
.withMessageRequest(messageRequest);
// send the message
AmazonPinpoint pinpointClient = AmazonPinpointClientBuilder.standard().build();
SendMessagesResult sendMessagesResult = pinpointClient.sendMessages(sendMessagesRequest);
MessageResponse messageResponse = sendMessagesResult.getMessageResponse();
}
