WhatsApp API usage fees

These are the fees that WhatsApp charges for using their API to send messages.

WhatsApp charges by 24-hour conversation windows, depending on who sent the first message. Once a conversation window is open, you can send any number of messages to this contact without extra fees.

Preguntas frecuentes

What will my final cost be?

Hilos will charge you for the plan you choose + extras you add.

All WhatsApp usage fees will be paid directly to WhatsApp (Meta).

Why does WhatsApp have a separate usage fee?

WhatsApp charges this fee to anyone wanting to use their API to send messages to their users. It's similar to how sending an SMS has a fee as well.

Why is the WhatsApp fee lower for user initiated conversations vs business initiated?

This is because WhatsApp wants to encourage end users to chat with businesses when it's relevant to them. However it doesn't mean that businesses can't start conversations with their users, it just means that it's slightly cheaper to have your users write to you.

Are there volume discounts?

Yes, if you have high messaging volume, need lots of inbox agents or specific SLAs or support needs, book a demo with us and we can prepare a custom pricing for you.

How do I pay?

Hilos will charge your saved credit card on Stripe at the beginning of the month for your subscription + past month's extra usage.

Payments can be made with a debit or credit card, and we process these payments through Stripe for a safe and secure experience. We do not store any Credit Card information on our servers.

You can also choose how to pay your WhatsApp fees directly on your company's Business Manager on Facebook.

Are there any extra fees for becoming an Official Business Account (OBA), or green tick?

With this feature, your company can have a green tick next to your name when a user opens a conversation with your company's phone number.

There is no extra fee for this service, but make sure you read 360Dialog and Meta's policies on the official requirements.

How do WhatsApp's conversations work?

Instead of charging you per message sent like with SMS, WhatsApp fees are assessed per 24hr conversation windows.

This means that when you first message a contact, WhatsApp opens a conversation and starts a 24hr timer. While you're inside that 24 hr window, you can send and receive unlimited messages with that contact, without extra fees.

However, if after those 24 hours another message is sent, WhatsApp will open a second 24 hr window and charge for it.

Can I cancel my Hilos subscription at any time?

Yes, our service is paid monthly and there are no cancellation fees or required stay.

If you decide not to use it for a month, you can pause your subscription and reactivate it whenever it makes sense for you.

Can Hilos charge my credit card automatically each month?

Sure! When you start your subscription we'll save your credit card on Stripe and use it every month to pay for your Hilos service automatically.

How can I pay the WhatsApp API fees?

You can add a credit card to your company's Facebook Business Manager account, and just like with their ads, you can choose your payment method and frecuency.

For example, you can set spending limits so you're charged whenever you go over them (say, everytime you've used $20 USD), or once a month, etc.
