Receive, route, and prioritize incoming messages sent by customers.
When a customer sends a message to a business, the customer's device sends that message to Business Chat. Business Chat then sends the message to the Customer Service Platform (CSP) by making a POST request to the
/message endpoint that the CSP implements (see Receiving Messages from the Business Chat Service). Business Chat waits up to 30 seconds for a response from the CSP before it times out the request.
After receiving the request from Business Chat, the CSP validates the incoming message (see Validating a Message) and returns the appropriate response code to Business Chat (see the "Response Codes" section in Integrating with Business Chat). The CSP may perform additional activities, such as downloading attachments, before forwarding the message to the business. Unless otherwise noted, all text fields support Basic Multilingual Plane of Unicode.
