Abstract: A message including metadata is received on behalf of an application operator from a subscriber by a message management platform. Based on the metadata, the message is determined to be associated with a customer record received by the message management platform as an application programming interface (API) notification from an application builder platform. The API notification includes a payload that includes information describing a committed transaction event associated with a user of the application builder platform. An interaction history associated with the subscriber is presented in a messaging interface of the message management platform. The interaction history includes the message received from the subscriber and further including a user action item describing the committed transaction event associated with the user of the application builder platform.

Abstract: A message management platform receives API payloads including past confirmed transactions carried out by an application builder platform and available item offerings of an application operator. The message management platform launches, at an instant messaging platform, a chat session between an agent and a user, a subscriber to the message management platform and an end-user of the application operator. The message management platform displays, for the agent, at the instant messaging platform, the past confirmed transactions of the user and the available item offerings of the application operator. The message management platform receives a selection of a set of items from the agent based on the chat session with the user and creates a virtual instance of a shopping cart representation. The message management platform generates a materialization link of the shopping cart and transmits the materialization link to the user through the instant messaging platform.
