The Twilio Add-on Management API is designed to help developers install and configure Twilio Add-ons programmatically, enabling features that require minimal manual intervention, thus enhancing the customer experience. The API allows users to associate specific phone numbers or messaging add-ons with Twilio phone numbers, limiting their invocation to only incoming calls or messages on those numbers. With the API, developers can build custom applications that leverage pre-integrated capabilities from Twilio partners, reducing time to market for new features and improving user engagement.
