REST-SMPP bridge from Melrose Labs that can be deployed on AWS API Gateway and AWS Lambda

Use REST calls to submit SMS text messages using an SMPP account. For use with any SMS gateway / aggregator / SMPP provider and not only Melrose Labs Tyr SMS Gateway.

Deploy in your own AWS API Gateway/Lambda instance or use existing Melrose Labs endpoint (no account required):

API Gateway calls lambda function to process REST call JSON payload and perform SMPP session. Multiple destination mobile number can be specified. Initial code in repository and will be updated with more capabilities and parameters in due course.
