Abstract: Techniques are provided for implementing omnichannel messaging. A set of application programming interfaces are utilized to create a set of channels connected to services of a customer platform. A channel is defined to specify how the channel is to interact with a service of the customer platform. Flows are formatted and defined for sending and receiving messages across the set of channels based upon native messaging experiences provided by the services of the customer platform. Flows are formatted and defined for viewing and interacting with the messages based upon a set of contexts for viewing and interacting with the messages through the services. The flows are executed for processing messages.
