Free WhatsApp API course: from zero to your AI agent in 5 days
One email per day for 5 days. No jargon. You learn to connect your number with API, create a no-code AI bot, automate WhatsApp with n8n and manage your conversations with a CRM.
WhatsApp API mini-course syllabus
5 practical emails. Each day you finish with something working — not just theory.
Day 1
What the WhatsApp API is and what it is for
You understand the difference between WhatsApp, WhatsApp Business and WhatsApp API. You see when it makes sense to use an API and when it does not. No jargon.
Day 2
Connect your number with a QR code (5 minutes)
You connect your WhatsApp number to waseller with a QR code, just like WhatsApp Web. In 5 minutes the number is active with API and you can already receive messages via webhook.
Day 3
Your first no-code AI bot with Bot Builder
You create your first AI agent by answering questions in the waseller Bot Builder. No coding. The bot already knows who you are and what you sell.
Day 4
Connect WhatsApp to n8n with the ready template
You import the pre-configured n8n workflow, connect it to your number and watch messages arrive in real time to your flows. Anti-loop, memory and automatic replies included.
Day 5
CRM to manage your conversations + wrap-up
You use the waseller CRM to view your contacts in a pipeline, reply to chats from the platform and manage your team. At the end, you know exactly which plan fits your case.

Frequently asked questions
Is the WhatsApp API course really free?
Yes, completely free. You receive 5 emails over 5 days. No credit card required. At the end you can try waseller free for 3 days if you want, but it is not mandatory.
Do I need to know how to code to follow the course?
No. The course is designed for people with no technical background. The first 3 days are code-free. On Day 4 you introduce n8n (also visual) with a template ready to import.
What is the difference between WhatsApp, WhatsApp Business and WhatsApp API?
WhatsApp is for personal conversations. WhatsApp Business adds a business profile but is still manual. WhatsApp API lets you automate messages, connect bots, use webhooks and manage hundreds of conversations from n8n or a CRM.
Can I automate WhatsApp without knowing how to code?
Yes. With the waseller Bot Builder you create an AI agent by answering questions in under 10 minutes — no code. For more advanced flows, n8n is a visual tool that requires no coding for most use cases.
