FAQs
Can I use the same number on the WhatsApp Business App and WhatsApp API?
Yes. WhatsApp Coexistence lets you use the same eligible business number on both the WhatsApp Business App and Cloud API. Supported 1:1 messages are mirrored between the app and the AiSensy dashboard, allowing you to reply from either interface.
Will I lose my existing chats after enabling WhatsApp Coexistence?
No. Your existing chats remain available inside the WhatsApp Business App. If you approve chat-history sharing during onboarding, up to the most recent six months of supported 1:1 conversations can also be synchronized with AiSensy. Group chats are not synchronized to Cloud API.
What are the requirements for WhatsApp Coexistence?
You need an active and eligible WhatsApp Business App number, access to the relevant Meta business setup, and a supported version of the WhatsApp Business App. Meta may also check the eligibility of your business account and number during onboarding.
Does WhatsApp Coexistence work in India?
Yes. WhatsApp Coexistence is available for eligible Indian business numbers. Nigeria and South Africa are also now supported, so they should not be listed as excluded countries. Availability may still depend on Meta’s account and number eligibility checks.
Is WhatsApp Coexistence free?
Meta does not list a separate Coexistence activation fee. Messages sent manually through the WhatsApp Business App continue to follow app rules, while messages sent through Cloud API are billed according to Meta’s applicable WhatsApp Business Platform pricing. AiSensy plan or service charges may also depend on the plan and features used.
How does WhatsApp Coexistence work day to day?
Customers continue messaging the same WhatsApp number. You can reply manually through the WhatsApp Business App, while your team manages supported conversations, automation, campaigns, integrations, and customer support through AiSensy.
Will my WhatsApp broadcast lists continue working?
Existing broadcast lists become read-only, and you cannot create new Business App broadcast lists after Coexistence onboarding. You can instead send API-powered broadcast campaigns through AiSensy with audience segmentation, templates, scheduling, and analytics.
Can I continue using WhatsApp groups?
Yes, group chats continue working inside the WhatsApp Business App. However, groups are not supported or synchronized through Cloud API, so they will not appear in the AiSensy dashboard.
How long does WhatsApp Coexistence setup take?
Setup time depends on number eligibility, Meta account checks, permissions, and onboarding requirements. The AiSensy team can guide you through the process, connect your existing number, and help test chat synchronization after setup.
