Frequently asked questions

WhatsApp Business API FAQs

Quick answers before you get started with WhatsApp integration.

Can I send invoices and bills through WhatsApp?

Yes. Your integrated application can send invoice notifications and supported document attachments through the WhatsApp Business Platform, subject to the applicable API capabilities and messaging rules.

Can I send both individual and bulk WhatsApp messages?

Yes. Integrations can support one-to-one notifications as well as bulk messaging workflows. Business-initiated messages generally need approved templates, and recipients must be contacted in line with WhatsApp policies and consent requirements.

Can you integrate WhatsApp with my existing software?

We can assess integration with websites, billing applications, CRMs, ERPs and custom software. The exact method depends on your software's APIs, database access, hosting and workflow requirements.

Can I use my own business number?

A dedicated business number may be used subject to Meta's number setup and eligibility requirements. Whether an existing number can be used alongside the WhatsApp Business app depends on the supported setup available to your account.

Will I definitely get the Meta Verified Blue Tick?

No. A badge is subject to Meta's eligibility rules, available verification options, any applicable fees and Meta's final decision. API integration alone does not guarantee verification.

Are WhatsApp messages free?

Messaging charges and applicable service or integration fees depend on Meta's current pricing, message category, recipient market and your chosen setup. Ask us for a quote based on your expected usage.
