Does anyone have a reliable way for checking if a number is a whatsapp linked number before sending a message to it?

Hi @average-megabyte-82737 , can you explain what you mean? Why do you want to check this?

Hi @acceptable-gold-88171 we want to do this to communicate to our existing client base from the botpress, at present communications are sent out via SMS however it lacks the interactivity available through the bot. However it would be wise to check which contact numbers are valid whatsapp accounts so only those communications are routed via the whatsapp botpress stream
