Although this is very interesting idea, which im willing to explore, BUT... the problem is that when clicked on a company (external)website. A template message will be sent to my clients' whatsapp like, "Hi [Client's name], im interested in the [Variable: xxx] from the following link: [Variable: sss.com]" for example. Im currently doing to start the bot by scanning the messages with Hi ..... im interested in.... as those are fixed.... BUT... wouldn't it be scanning ALL messages... even for the filters you are mentioning?
