Cloud API Only

Enterprise scalability
Multi-agent team inboxes
CRM & automation support
Check calling API eligibility
Choose your API interface
Agree migration and history scope

Check standard and hybrid account conditions

Standard and hybrid planning comparison
Aspect	Standard Cloud API	Hybrid Coexistence
Operating model	API integration with your chosen interface	Business App alongside API, subject to eligibility
Throughput and recipient limits	Check actual account limits	Check actual hybrid account limits
History, media and devices	Agree migration and retention scope	Confirm import, sync and linked-device scope
Calls, groups and app features	Confirm API/version/region support	Confirm each app/API feature separately
Region and onboarding	Check number/account/provider eligibility	Check country, app version and rollout
Billing	Effective category/rate; platform fees separate	Distinguish app and API traffic; confirm tariffs

Identify whether the number is on the Business App, already API-only or new. Assess coexistence and standard registration separately. Do not delete, deactivate, disconnect or re-register a working account based on this guide; agree a supported migration, backup and recovery plan first.

Onboarding, verification, template review and integration timing depend on the account, provider, workflow and outstanding approvals. Confirm the scope and schedule with the team; no instant approval, fixed waiting period or go-live deadline is promised.

Choose a path before changing the number

Existing Business App number

Assess hybrid eligibility before changing the working app; confirm import and device needs.

Number already on Cloud API

Request a supported transition plan. Do not assume an API-only number can switch to hybrid directly.

New number or eligibility unknown

Compare standard registration and hybrid requirements with the provider. A country or plan name alone is not approval.

Strategic Benefits for Microbusinesses

Hybrid Engagement

Automate lead qualification with chatbots, then seamlessly handoff to human agents for voice calls and personalized follow-ups.

Cost Optimization

Separate manual app traffic from API traffic and confirm effective rates, eligible categories and account conditions before budgeting.

Lower CAC

Confirm the effective entry-window and category conditions for ad-driven follow-ups; no universal zero-price or acquisition saving is established.

Industry Use Cases

Illustrative workflows to discuss after account eligibility and feature support are confirmed. These examples do not establish that every integration is shipped for your account.

Automated Layer (API)

• Capture leads from Facebook/Instagram ads
• Send property brochures automatically
• Collect budget & location preferences
• Schedule site visits in CRM calendar

Human Layer (Mobile)

• Personalized voice notes for inquiries
• Video calls for overseas buyers
• Share live property walkthroughs
• Negotiate deals with voice calls

Implementation requirements and regional availability

Check the onboarding flow for the exact number and country, supported app version, provider access and business permissions. Country lists and fixed warm-up or inactivity periods are not confirmed here.

Confirm whether history and media import is offered, which records are included, consent, linked-device support and synchronization behavior. No fixed import period, device count or complete CRM history is guaranteed.

Treat linked devices, calls, groups, badges and marketing integrations as separate eligibility checks. Monitor connection state before scheduling automations.

Frequently Asked Questions

Can I keep my existing number and Business App?

Coexistence is an option to assess for an existing Business App number. Confirm eligibility for that number, account, country, app/API version and rollout before planning a hybrid setup. This guide does not confirm availability for your account. Identify whether the number is on the Business App, already API-only or new. Assess coexistence and standard registration separately. Do not delete, deactivate, disconnect or re-register a working account based on this guide; agree a supported migration, backup and recovery plan first.

What throughput can I expect?

Throughput in messages per second is separate from recipient messaging limits, template pacing and quality restrictions. Standard and hybrid limits must be checked for the actual account; no fixed MPS or universal upgrade is confirmed here.

Will all my chats, media and linked devices carry over?

What happens if I change phones or stop using the app?

Confirm the current activity, device-change, disconnection and recovery rules for your account. Monitor connection status and pause affected automations while investigating; no fixed inactivity deadline or automatic reconnection is promised here.

Are calling, verification badges and marketing APIs compatible?

Check each feature against the current API/app version, country, provider and account eligibility. A standard or hybrid label does not confirm calling, group access, a verification badge or a marketing API integration.

Does a service or entry window guarantee free messaging?

A customer message opens or resets the 24-hour reply window. Outside it, an approved template is needed. Permission to use a message format does not determine its price; confirm the effective category, allowance and account conditions separately. Eligible Click-to-WhatsApp ad entry on Android or iOS can open a free-entry window when the business replies within the customer-service window. The window starts with that response and can last up to 7 days, subject to Meta’s actual eligibility and expiry. During that window, Marketing, Utility, Authentication and Service deliveries are free for that business phone number/customer pair across messaging accounts. An ad click alone or desktop/web entry does not establish this exemption. Confirm the actual window before excluding deliveries. An accepted send is not proof of delivery or final billing; unresolved pricing evidence remains unresolved.
