Hey Jeanette!Right now, your best option is to use Pipechat, which was actually created by one of our PD developers. @Daniele is the best person for any questions you might have.
Hey Jeanette! There are a couple of marketplace apps that can do this. You can check them out here:
Take a look at Suiteshare here:
It seems to be a good tool to connect pipedrive and whatsapp.
If you can't do it, feel free to ask and I'll try to help you.
If you just want to open a phone number in WhatsApp chat (web or mobile), simply prefix https://wa.me/ to the complete phone number (with ISD code, without +, -, spaces).
For instance, you can WhatsApp me by clicking https://wa.me/919860665934.
I have created a custom field in Pipedrive where I create this link in Zapier when creating the contact.
