You can now send attachments directly through Amazon Connect Chat, making it easier than ever to resolve your customers’ support needs. For example, an agent can send a copy of a recent hotel invoice or a customer can share a photo of a damaged product. Attachments are included in the chat transcript, to help ensure the full context from the conversation is available if a contact is transferred to another agent. The files are also stored in your S3 bucket to allow access from other systems such as customer relationship management or case management systems. You can turn attachments on in the AWS console with a couple of clicks.
