Connect WhatsApp Business API

Use Meta's embedded signup to link your WhatsApp Business number — no code, no server, no agency needed.

The WhatsApp Business API is Meta's official interface for businesses to send and receive WhatsApp messages at scale. Unlike the free WhatsApp Business App, the API supports multiple agents, automated bots, CRM integrations, and broadcast campaigns — all managed from a single dashboard.

If you have access — follow the steps below to connect directly.

If you don't have access — use the Generate Link feature at the bottom of the Channels page. Send the link to your marketing team or agency — they can complete setup without logging into SendSeven.

FAQ

Do I need access to Meta Business Suite?

Yes. The setup requires a Meta Business account. This access is usually managed by the marketing team. If you don't have access, use the Generate Link feature at the bottom of the Channels page to send a setup link to someone who does — they can complete the connection without logging into SendSeven.

Can I use my existing WhatsApp number?

Yes, but the number must not be actively registered with the regular WhatsApp or WhatsApp Business app. You'll need to unregister it first inside the WhatsApp app settings before connecting it here.

What types of phone numbers can I use?

You can use a mobile number, a landline, or a toll-free number — as long as it can receive international calls. Choose Text message for mobile numbers and Phone call for landlines and toll-free numbers during verification.

What happens if I don't add a payment method?

Without a payment method you can receive messages and reply freely within the 24-hour service window. However, you cannot send marketing or authentication templates, run broadcast campaigns, or message more than 250 unique contacts per day. You can add a payment method later inside Meta Business Suite at any time.

What is the 24-hour service window?

When a customer sends you a message, a 24-hour service window opens. During this window you can reply with any content (text, images, documents) for free. You can also send utility templates for free within this window. Outside the window you must use a Meta-approved template message.

Can I connect multiple WhatsApp numbers?

Yes. Each number is a separate channel in your SendSeven workspace. There is no limit on the number of connected WhatsApp channels.

What message types are supported?

SendSeven supports all WhatsApp message types: text, images, documents, interactive buttons (up to 3), list menus, and carousel templates. Template messages must be pre-approved by Meta and are categorised as marketing, utility, or authentication.
