Freelance WhatsApp API Developer in Seoul

Freelance WhatsApp Business API developer for Seoul, South Korea: WhatsApp Business API, chatbots and automation. Planned for PIPA and local payments.

Overview

WhatsApp Business Platform (Cloud API) set-up — verified sender, approved templates, chatbots, order and appointment notifications, and CRM integration. Projects for Seoul run remotely, with about 4.5 hours of overlap with a 9-to-6 working day. Scope, milestones and ownership are agreed in writing before work starts.

South Korea-specific requirements to plan for

Projects for businesses in Seoul have to work for local customers and local rules. These points are planned from the first milestone:

  • Channels that matter most in South Korea: KakaoTalk, Naver Blog, Instagram and YouTube.
  • Personal Information Protection Act (PIPA): PIPA is one of the strictest privacy laws in Asia — separate consents are often needed for marketing and third-party sharing.
  • Interface and content languages: Korean.

This is practical delivery guidance, not legal advice.
