Programmable SMS - API Basics and Best Practices

Twilio's Messaging API allows developers to send and receive SMS messages with ease. To authenticate, developers need to provide their Twilio Account SID and Auth Token, along with the recipient and sender phone numbers. The API has various features such as webhooks, TwiML, and message logs, which can be used to handle incoming and outgoing messages, as well as track delivery status. However, sending a large volume of messages quickly can cause throughput issues, and developers should use Twilio's Copilot service or implement their own queuing system to manage this. Additionally, the API has rate limits in place to prevent abuse, and developers should be aware of character encoding limitations when sending SMS messages.
