WhatsApp API for OTP, alerts, and campaigns

Official WhatsApp Business API to the customer’s WhatsApp number. Templates, session replies, and software-triggered notifications — not the personal app, not unofficial bulk tools. SMS to the phone inbox is a separate page.

WhatsApp only. Advance messaging plans can add this channel; Premium includes it. SMS packages stay on the SMS page.

Outbound

WhatsApp campaigns

Opted-in marketing templates for batches, offers, and events. Separate from utility alerts. We do not scrape numbers or run unofficial bulk senders.

Setup

Business verification

Display name, business number, and Meta verification so templates can be submitted. We walk your office through the steps instead of a blank BSP portal.

Integration

API from your software

Fire templates from the school product, website, or custom app when an event happens (fee due, order paid). You keep the contact list; we wire the official API.

How we work

  1. 1. Verify

    Business number and Meta verification so templates can be submitted.

  2. 2. Integrate

    Official API plus an inbox for session replies. Your software keeps the contacts.

  3. 3. Send and review

    Approved templates only. We report what sent and what Meta or the user rejected.

Who it is for

Schools, shops, and apps in Bihar whose customers already use WhatsApp and need official templates — not a shared staff phone. If you only need the phone inbox, use SMS.

Questions about WhatsApp API

Is this personal WhatsApp?

No. This is WhatsApp Business API through official Meta-approved providers: a business number, approved templates, and an inbox your staff can use. Not the green personal app and not unofficial “WhatsApp blasters”.

Can we send OTP and alerts on WhatsApp?

Yes, where Meta allows the template category. Utility templates cover fee due, order packed, and slot confirmed. Marketing templates are separate. Some OTP use-cases still belong on SMS.

Do we still need SMS?

Often yes. SMS reaches the phone inbox when WhatsApp is not installed, the user blocked the business, or an OTP must go on a transactional SMS route. SMS is a separate service page.

Who approves templates?

Meta. We draft the copy and submit. We do not promise a template will be approved or that every user will receive it.
