How does this work?

1

Sign up for an onboarding

Book a call with our founder here: https://zcal.co/den/meet, to answer any questions you have, test out the API and understand your needs better. Maybe you'll even get a discount - if you can convince us.

2

Connect your WhatsApp numbers

During the call, we'll personally help you connect your WhatsApp number to our service so you can test it out. If you subscribe, we'll keep the connection live, if not, we'll cut it off right then.

3

Review the documentation, or the sample prompts

Now that your phone is set up, you can start sending messages.
