Connecting a WhatsApp Business number lets your AI agent answer customers on WhatsApp and lets you send campaigns and templates from that number. You connect it once through Meta’s sign-up window; Popcorn handles the registration and keeps the number’s message limit in sync afterwards.

Before you start

  • A Meta login that can manage your business. The sign-up runs in Meta’s own window.
  • A phone number for the business. Meta verifies it during sign-up. If the number is already in use on the WhatsApp Business app and you want to keep using the app, follow Use Popcorn with the WhatsApp Business app instead.
  • A role with edit access to Integrations. See Team and roles.
  • Optional: a Meta catalog, if you want customers to receive product cards on WhatsApp. You can also set this up later from the Account tab. See Products in WhatsApp.

Connect the number

1

Open the WhatsApp channel

Go to Channels → WhatsApp. If no number is connected yet you see Connect your WhatsApp Business Account. If you already have a number, open the Account tab and click Connect another number.
2

Click Login with Facebook

If your workspace already has products, Popcorn first asks Bring your products to WhatsApp?. Choose WhatsApp only to connect just the number, or I have a catalog — continue to authorize the number and your Meta catalog in the same sign-in. If you do not have a catalog yet, Create one first opens Meta Commerce Manager; create it there, then click I created it — continue.
3

Complete Meta's sign-up

In Meta’s window, log in, pick or create the WhatsApp Business account, and add the phone number. Meta also offers to connect a number that is already on the WhatsApp Business app; see coexistence before choosing that option. Whichever option you pick, Popcorn asks Meta whether the number is on the WhatsApp Business app and, if it is, connects it as a coexistence number. Finish every step of Meta’s flow. If you close the window early, Popcorn shows Cancelled and nothing is connected.

Wait for confirmation

Back in Popcorn you see Your WhatsApp Business Account has been set up successfully. It may take up to 15 minutes to start receiving messages. The number appears under Connected Numbers on the Account tab.
5

Connect the number to an agent

Open the agent, go to its Channels tab, click Connect next to the number, and click Publish changes. Until then the number is handled by your default agent. See Connect knowledge, tools and channels.
Meta’s window must open from your click. If Meta’s sign-in script was still loading, the first click shows Facebook is ready. Click Connect again to continue. and nothing opens; click Login with Facebook again.
While the number connects, Popcorn registers it with Meta using a two-step verification PIN that Popcorn generates and stores for you, links the number to your workspace, reads the number’s message limit from Meta, and, if it is your first number, makes it the default. If the WhatsApp Business account you picked contains several numbers, all of them are connected. A number that Meta reports as being on the WhatsApp Business app skips the registration step and is connected as a coexistence number instead. If you chose to include your catalog, the catalog connection starts automatically once the number is connected.

If the connection fails

Popcorn shows the reason in the error notification. The most common ones: More cases are covered in Channel troubleshooting.

The Account tab

Connected Numbers lists every number in your workspace. The menu at the end of each row offers Make default (for numbers that are not the default), and Delete or, for coexistence numbers, How to disconnect. Connect another number below the table starts the sign-up again.

Message limits

Meta limits how many customers a number can start a conversation with in a 24-hour period. The limit belongs to your Meta business portfolio, so every number in the same WhatsApp Business account shares it. Popcorn reads it from Meta when you connect, refreshes it every 24 hours, and applies updates Meta sends when the limit changes. The tiers Meta uses are 250, 1K, 2K, 10K, 100K and Unlimited, shown as 250 messages/day up to Unlimited messages/day.
  • Syncing with Meta… means Popcorn does not have a confirmed limit for this number. Campaign messages from it are held and retried every minute until the limit is known; if it is still unknown after about an hour, those messages are marked as failed. If the column stays on Syncing with Meta… for more than a day, Meta no longer accepts Popcorn’s access to the number: connect it again with Login with Facebook, which refreshes the access and starts the sync again.
  • Limit unavailable means Meta returned a temporary error. Popcorn retries automatically, starting 15 minutes later and spacing retries out to once a day.
Campaign sending stays within the limit and marks recipients that cannot be reached; see Delivery and reachability.

Make a number the default

The default number is preselected as the sender for campaigns and templates and is the number the Profile tab opens on. See what the default number means.
1

Open the row menu

On the Account tab, open the menu at the end of the row of the number you want.
2

Click Make default

Popcorn confirms with Default WhatsApp number updated. The Default badge moves to that number. Campaigns you already created keep their own sender.
Make default only appears if your role can edit Integrations. If you see Could not update the default WhatsApp number, reload the page and try again.

Delete a number

Deleting a number deregisters it from Popcorn’s connection at Meta and removes it from your workspace. The confirmation reads Are you sure you want to delete this WhatsApp account? This action cannot be undone. To use the number again you connect it from scratch with Login with Facebook.
1

Open the row menu and click Delete

On the Account tab, open the menu at the end of the number’s row and click Delete.
2

Confirm

Click Delete in the confirmation dialog. If Meta cannot deregister the number, Popcorn shows the error and keeps the number connected.
If you delete the default number, the most recently updated remaining number becomes the default. Numbers connected through the WhatsApp Business app cannot be deleted from Popcorn; use How to disconnect and follow disconnecting a coexistence number.

Settings on the Account tab

Below the table, the Settings section holds workspace-wide WhatsApp options:
  • Products in WhatsApp: connect a Meta catalog so customers can browse your products and receive product cards. The button reads Set up products, Continue setup when a previous setup is incomplete (with an Action required badge), or Connected. Once connected, Meta catalog health shows how many products are live, and the Product Sharing and Cart Checkout toggles appear. See Products in WhatsApp.
  • WhatsApp app message behavior: appears only when at least one number is a coexistence number. See Use Popcorn with the WhatsApp Business app.
Toggles are not saved immediately: a bar with Save changes and Discard appears while you have Unsaved changes. Popcorn confirms with Settings Updated.
