After installing Galantis on Shopify, the next step is connecting WhatsApp. Galantis launches Meta’s official Embedded Signup modal inside the app — a Facebook-hosted pop-up that handles every step of attaching a WhatsApp Business Account (WABA): logging into Meta, picking or creating your Meta Business, registering a phone number, choosing a display name, and verifying ownership. You stay inside the Galantis app the whole time. If you already have a WABA — including a number from the WhatsApp Business mobile app — the same modal lets you connect or migrate it in the same flow. No separate Meta dashboard visit, no manual token handling.

​
What is Embedded Signup?

Embedded Signup is Meta’s recommended onboarding flow for Tech Provider apps like Galantis. Instead of asking you to set things up in Meta Business Manager and copy access tokens, the modal walks you through everything in one place and returns the credentials Galantis needs automatically. From your point of view, it’s a single pop-up with 5–7 steps.
You don’t need a pre-existing WABA or Meta access token. The modal creates them for you if needed — or attaches your existing ones if you have them.

​
Before you start

  • Have your Facebook or Meta Business credentials ready (the email and password you use to log into Meta Business Manager)
  • Decide which phone number you’ll connect — see Choose a phone number
  • Make sure the number can receive an SMS or voice call for verification
  • If you’re migrating from the WhatsApp Business mobile app, keep the device with the app available — Meta may ask you to confirm the migration there

​
Pick your starting point

You’re setting up your first WhatsApp Business Account. The modal will create your WABA, attach a phone number, and verify it — all in one pass.
1

Open the Galantis app and click Connect WhatsApp

On the in-app onboarding screen (or under Settings → WhatsApp Connection afterward), click Connect WhatsApp. Meta’s Embedded Signup modal opens inside the app.
2

Log in to Facebook / Meta

Use the Facebook account that administrates (or will administrate) your Meta Business. If you’re not signed in, the modal shows the standard Facebook login screen.
3

Choose or create your Meta Business

Select an existing Meta Business if you already have one (for example, for Facebook/Instagram ads). Otherwise create one in the modal — give it your store name and confirm your country.
4

Create your WhatsApp Business Account (WABA)

Confirm the name of your WABA. This is internal — customers don’t see it; they see your phone number’s display name.
5

Add your phone number

Enter the number you decided on in Choose a phone number. Meta will send a 6-digit code via SMS or voice call — enter it in the modal to confirm ownership.
6

Set your display name

Pick the name customers will see in WhatsApp alongside your number — typically your store or brand name. Meta reviews display names; approval is usually quick but can take 1–2 business days. See Meta’s guidelines for naming rules.
7

Done — Galantis takes it from here

The modal closes and Galantis receives the credentials. You land in the Galantis dashboard, ready to set up your first campaign.

​
How to know it worked

Once the modal closes successfully, three things confirm the connection:

WhatsApp tab in Galantis

The Galantis dashboard shows your connected WABA name, phone number, and display name under Settings → WhatsApp Connection.

Verified status

The number shows a “Verified” or “Pending verification” badge. Marketing-category messages require display-name approval (1–2 days); utility-category messages are sendable immediately.

Test message

From Templates, send a test utility template to your own phone. A delivered message is the cleanest proof the connection works end-to-end.

​
Adding more numbers later

You can attach additional phone numbers to the same WABA after the initial connection — useful as your store scales to multiple brands, regions, or message types. Open Settings → WhatsApp Connection → Add number to re-launch the Embedded Signup modal for the additional number. See Multiple phone numbers for when and why to use more than one.

​
Troubleshooting

Check your browser’s pop-up blocker — the Embedded Signup modal is a Facebook-hosted pop-up. Allow pop-ups for the Galantis app domain and try again. If you’re using strict privacy extensions, temporarily disable them for this session.
Make sure the number is correct including country code, and that it can receive international SMS or calls. Retry in the modal — Meta sends a new code each time. If the number is a VoIP or toll-free number, it may not be supported; check Meta’s phone number requirements.
Meta rejects names that contain URLs, email addresses, promotional language (“Best”, “Cheap”, “Sale”), all-caps shouting, or that don’t match your brand. Resubmit with a clear brand-aligned name. See Meta’s display name guidelines.
The modal will explain the specific reason — usually an owner mismatch (the Meta Business doing the migration is different from the one that originally registered the number) or a Meta-side hold. Contact Galantis support with the modal’s error message and we’ll guide the next step.
