The number

Your messages, from your number
Connect your number and upload your list. Meta bills WhatsApp usage directly to your business, while Masar shows its management fee before you send. The two charges stay separate.
The Masar team reviews your account before enabling sending. You can prepare your data while you wait, and we will notify you when a decision is made.

What happens in Masar
A simple start
Three ordered steps. At each one, you can see what happened and what needs your decision.
The number
Connect through Meta in a few clear steps. The number, WhatsApp Business account and Meta payment method stay under your company; Masar manages the sending workflow.
The list
After a CSV upload, you see what was accepted, what was refused, and the line number that needs fixing. We do not guess ambiguous numbers.
Send
You see Masar’s management fee before launch. It is reserved once, then sent messages draw it down and unsent fees return. Meta bills WhatsApp usage separately and directly.
Two clear bills, no double charge
WhatsApp message charges go directly to your Meta business account. Your separate Masar balance covers management and operations, and every balance change is itemized.
Campaign statement
Every balance change is linked to the campaign that caused it
We calculate the management fee over your actual audience and show it beside the send button. It never bundles what Meta bills to your account.
The management fee you approve is reserved in one movement, then drawn down as messages go out.
Masar’s fee for anything WhatsApp refuses or confirms as failed returns to your Masar balance. Meta’s charges remain visible in your Meta billing account.
Masar top ups, management fees, refunds and settlements appear on one statement, clearly separate from Meta’s invoice.
Protect your number
Number health does not begin after reports arrive. It begins with clear proof of consent and a check that runs for every send.
This protection is part of the sending path, not a setting you have to remember to turn on.
Choose a plan
The plan sets usage limits and features. Meta sets and bills WhatsApp usage directly to your business account.

Answers about connecting your number, customer consent, campaign costs, and integrations.
Yes, when the number is eligible to connect. The Masar team reviews the account and number first, then shows the connection status and the next required step before sending is enabled.
Campaigns are for customers who agreed to receive messages through WhatsApp or the selected sending service. Masar keeps the consent evidence, checks it at send time, and respects opt-outs before another message leaves.
Meta shows and bills WhatsApp usage in your business account. Masar shows its separate management fee before confirmation, then returns the fee for anything unsent to your Masar balance. You never pay Meta’s charge twice.
Business-initiated messages need a usable template under WhatsApp rules. Masar shows each template status and will not send one whose current state does not allow it.
Yes. The platform provides a scoped REST API, an OpenAPI specification, and signed webhooks for message status and event updates inside your own system.
