How the connection works
Assistaffer is registered with Meta as a Tech Provider for the WhatsApp Business Platform.
Instead of asking you to create a Meta Developer App, add the WhatsApp product, and copy technical IDs by hand, Assistaffer uses Meta's official onboarding flow — called Embedded Signup, and referred to on this page as Meta Onboarding — to request permission to send and receive WhatsApp messages for your business number.
You approve the connection inside a secure pop-up window hosted by Meta and Facebook. Assistaffer never sees your Facebook password, and Meta hands back only the technical identifiers Assistaffer needs to operate your number — nothing else.
Meta concepts, explained
Meta uses its own terminology throughout the onboarding pop-up. Here's what each term means.
Meta Business Portfolio
The umbrella Meta account that owns your business's assets — Facebook Pages, ad accounts, and WhatsApp Business Accounts. If your business doesn't have one yet, Meta lets you create one during onboarding.
WhatsApp Business Account (WABA)
A container inside your Meta Business Portfolio that holds one or more WhatsApp phone numbers and message templates. Each Assistaffer organization connects to exactly one WhatsApp Business Account.
Phone Number & Phone Number ID
The Phone Number is the number your customers message. The Phone Number ID is a separate numeric identifier Meta assigns to that number — Assistaffer uses this ID, not the number itself, to send and receive messages through Meta's API.
Meta Onboarding (Embedded Signup)
Meta's official guided flow for connecting a WhatsApp number to a Tech Provider like Assistaffer. It opens as a secure pop-up window where you log in with Facebook and approve only the specific permissions Assistaffer is requesting.
Coexistence
If your number is already active in the WhatsApp Business App on your phone, Meta offers to link it to Assistaffer instead of requiring a new number. Your number keeps working in the WhatsApp Business App while Assistaffer also sends and receives messages through it.
Meta Access Token
The credential Meta issues to Assistaffer once you approve the connection. It's what lets Assistaffer send and receive messages on your behalf. It's stored securely and never shown again after the connection completes.
Meta Messaging Charges
Meta's own per-conversation fees for sending and receiving WhatsApp messages, billed directly to your business by Meta. These charges are entirely separate from, and in addition to, your Assistaffer subscription.
Webhook (already configured)
The mechanism Meta uses to deliver incoming messages to Assistaffer in real time. Because Assistaffer is a registered Tech Provider, this is already set up platform-wide — you don't need to configure or verify anything in Meta yourself.
Connect your WhatsApp number
What you'll actually do — most of it happens inside Meta's own pop-up.
- Open your organization's Settings page in Assistaffer (requires the Basic or Premium plan) and find the WhatsApp Chat bot Phone configuration section.
- Read the notice explaining that Meta Messaging Charges are billed by Meta directly and are separate from your Assistaffer subscription.
- Click Setup WhatsApp... — this opens Meta Onboarding immediately in a pop-up window hosted by Facebook.
- Log in with your Facebook account and select — or create — the Meta Business Portfolio that should own your WhatsApp number.
- Choose or create your WhatsApp Business Account and phone number. If your number is already active in the WhatsApp Business App, accept Meta's Coexistence option to link it without losing your existing chats.
- Review and approve the permissions Meta lists — sending and managing WhatsApp messages on your behalf — then let the pop-up close.
- Done automatically: Assistaffer saves your WhatsApp Phone Number, Phone Number ID, WhatsApp Business Account ID, and Meta Access Token without any copying or pasting.
After you connect
A couple of things to check once Meta Onboarding completes.
- If your organization isn't already on a paid plan, activate your subscription — the chatbot only responds to messages once the subscription is active.
- Send a test WhatsApp message to your business number to confirm the AI booking agent replies.
- To reconnect later — for example if you revoke access in Meta, or move your number to a different Meta Business Portfolio — simply run Meta Onboarding again from organization Settings; it overwrites the stored connection.
