Automate sender ID registration in AWS End User Messaging

This article explains how to automate sender ID registration in AWS End User Messaging using Python scripts and APIs for Indonesia and India.

• Sender IDs enable businesses to send SMS using alphanumeric identifiers instead of phone numbers
• Key APIs: DescribeRegistrationTypeDefinitions, CreateRegistration, PutRegistrationFieldValue, SubmitRegistrationVersion
• Registration workflow: retrieve definitions, create registration, populate fields, upload attachments, submit for review
• Indonesia requires multiple Letters of Authorization (LOA) and regulatory documents from local carriers
• India registration (available April 30, 2025 in Mumbai and Hyderabad regions) requires TRAI entity ID and chain IDs
• Third-party reviewers evaluate registrations; expect 2-4 weeks for approval in most countries
• Python scripts provided for both Indonesia and India with configurable parameters
• Registration status progresses from CREATED to REVIEWING to COMPLETE or REQUIRES_UPDATES
• ISVs must provide end-customer business information, not ISV information, for registrations

The post provides complete automation scripts and configuration templates to streamline sender ID registration across multiple countries with country-specific requirements.
