- Do something (user checks box, pushes button)
- Make it clear that you will be communicating through WhatsApp
- Mention your business/legal name
- Describe here for how many times in a day they will listen to you.
Failsafe tip: Do not rely on pre-checked boxes, or past SMS consent counts – explicit WhatsApp opt-in is needed.
Message Templates: Pre-Approved before Sent
All business-initiated messages (e.g., transaction alerts, appointment reminders or promotional messages) must be authored and approved via Meta’s system.
These templates must:

Respect the 24-Hour Window Rule
When a user sends you a message, you have 24 hours to respond with any free-form reply. And now, after 24 hours, you are limited to only using approved message templates.
This is designed to limit spam and promote appropriate assistance – a basic compliance architecture.
Maintain Accurate Business Representation
Your WhatsApp Business profile should contain the following:
- Correct legal business name
- Address and contact details
- Official branded / domain verified whatsApp.com
Meta has oversight and if it finds inconsistencies (like what is in your Meta Business Manager and WhatsApp listing) they may lead to delays in approval or account restriction.
Data Security and Privacy Standards
Not just messaging, but data handling.
You must:
- Protect customer data with encryption
- Collect minimal necessary data
- Comply with global privacy laws such as GDPR, CCPA etc. WhatsApp Business
Plus, procedures must exist for:
- Data retention
- Audit logs
- Deletion upon request

Global operations mean global laws. In Europe, companies need to be compliant with GDPR. In India, there local privacy laws demand clear communication and storage.
What is legal in one market might be forbidden in another compliance teams can’t just generalize policies across markets.
WhatsApp API Policy Update 2026- What’s New?
As of the 15th of January, 2026, Meta made some big changes which have a significant impact on how businesses will utilize the WhatsApp API:
Ban of General-Purpose AI Chatbots
Meta has now banned the use of mainstream chatbots from running on its WhatsApp Business API.
This means:
- ChatGPT, Perplexity, Copilot-style bots as for now there is no way to even chat with users through WhatsApp.
- You can use only business automation flows (support bots, booking bots, order bots).
- Bot behavior must have clear, predictable results associated with business messaging not an open-ended AI chat.
This change puts usage in line exclusively with business applications for communication, not conversational AI fun.
Why This Update Matters
For developers and marketers:
- Bot flows need to be refactored for compliance
- No free-roaming queries or open AI interactions
- AI use should be in the service of concrete business tasks
If your bot used to employ AI in the background to understand any user input, it will have to be revamped to continue being compliant.
