The Amazon Chime SDK lets developers add real-time audio, video, screen share, and messaging capabilities to their web or mobile applications. Starting today, the Amazon Chime SDK allows developers to execute business logic on in-flight messages before they are delivered to members of a messaging channel with channel flows. Using channel flows you can create flows that remove sensitive data such as government ID numbers, phone numbers, or profanity from messages before they are delivered, which may be helpful for implementing corporate communications policies or other communication guidelines. Channel flows can also be used to perform functions like aggregation of responses to a poll before sending results back to participants.
