We’ve recently released Advanced Opt-in / Opt-out, which allows users to configure custom keyword, auto response & block rule operations for their respective messaging profiles.
Advanced Opt In / Out allows users to configure and personalise their own auto response behaviour, negating the need to implement their own mechanisms in order to align with industry standards.
You can now optionally personalise configurations to trigger based on inbound messages from specific countries, allowing for localised language support for your brand.
All of this is now achievable via the UI in our Mission Control portal.
API Reference can be found here.
