}FAQ
Questions developers and business owners ask first.
Is this the official WhatsApp Business API?
Advika connects businesses to WhatsApp Cloud API workflows and exposes developer endpoints so your product can send approved WhatsApp messages through an Advika workspace.
Do customers still need their own Meta payment method?
Yes. Meta message charges are managed by the connected WhatsApp Business Account. Advika covers platform features, automation, API access, inbox, ads tooling, and workspace controls.
Can I use this API inside my own SaaS or CRM?
Yes. Generate an API key inside Advika, call the WhatsApp developer endpoints from your backend, and use webhooks to receive delivery and reply events.
Can I send marketing messages?
Marketing sends must use approved WhatsApp templates and follow Meta policies. Advika helps manage templates, campaigns, delivery visibility, and contact activity.
