we are on ACC v7, and moving to v8 shortly, had use case where I need to send the invoices to the customers via message Center when Realtime event is triggered , however my question is can we receive binary PDF file content /binary forms in the payload and attach it to the message and send it. Is it possible in ACC? any documentation links would be helpful.
uploading it to CDN and use it is another option we are exploring as well.
