WhatsApp Business API in Vietnam

Chronex360 provides WhatsApp Business API services in Vietnam for businesses targeting international buyers, cross-border e-commerce customers and Vietnamese audiences already active on WhatsApp, while noting that Zalo and Facebook Messenger are the dominant local messaging apps. Facebook and Instagram enquiries can be unified into one lead pipeline with automated qualification, agent assignment and conversion reporting.

Compliance watchpoints

Vietnam's Decree No. 13/2023/ND-CP on personal data protection (in effect since 1 July 2023, and superseded by a new national Personal Data Protection Law effective 1 January 2026) requires informed, opt-in consent before using personal data for marketing, with clear disclosure of content, method and frequency.

How to launch on Chronex360

Use WhatsApp for export/B2B buyers and internationally-facing customer service, with Zalo and Messenger as the primary domestic consumer channels. Route qualified leads from all channels into Chronex360 for consistent follow-up and reporting.

Recommended social-to-WhatsApp growth flow

Meta ad / Instagram DM / Facebook message → Chronex360 lead source → WhatsApp qualification → agent assignment → task or schedule → proposal/catalogue/order → follow-up → conversion reporting. Use Marketing templates only for opted-in promotional outreach; use Utility for requested/transaction-triggered updates; use Service replies when the customer starts the conversation.

What to track

Lead volume by source, opt-in rate, first-response time, qualified-lead rate, agent follow-up adherence, template delivery/reply rate, conversion rate, order/revenue attribution where applicable, and opt-out/blocked rate.
