Use this guide when Embedded Signup for WhatsApp Coexistence says that your phone number is already connected to a business partner. First check where the connection is listed, then follow the resolution steps only when neither place shows a partner.

​
Check where the partner is connected

When you see this error, check these locations in order:
  1. In the WhatsApp Business app, open Settings > Account > WhatsApp Business Platform.
  2. If a connected partner is shown, tap Disconnect, then try Embedded Signup again.
  3. If no partner is shown, open your Meta Business Portfolio at business.facebook.com and check the number under Settings > Partners.
  4. If a partner is listed there, remove it, then try Embedded Signup again.
  5. If neither location shows a partner, continue with Resolve the issue below.
For other signup errors, see Signup Troubleshooting. If no partner appears in either location, contact the Eazybe Support team before you continue with Resolve the issue. They can confirm whether the reset is required for your number.
The steps under Resolve the issue reset the number’s connection state and make it behave like a new number. Existing WhatsApp Business data, including old message templates, may be deleted and may not be recoverable. Continue only after you have contacted Eazybe Support and understand this impact.
Complete every step, in order, on the phone that holds the WhatsApp Business number. If you skip the backup in Step 1, your chats are lost when you uninstall the app.

Resolve the issue

1

Take a chat backup

Open WhatsApp Business and go to Settings > Chats > Chat backup. Start the backup and wait for it to finish before you move on.
On Android the backup is saved to Google Drive, on iPhone to iCloud. The backup is complete when the screen shows a fresh time under the last backup. Anything not included in this backup will not come back after you reinstall.
2

Uninstall WhatsApp Business

Uninstall the WhatsApp Business app from your phone, the same way you remove any other app.
Do not delete your WhatsApp Business account from the app’s Account settings. Deleting the account wipes the number’s history with Meta and can push it into a cooldown period. Remove the app only.
3

Install regular WhatsApp

Install the regular WhatsApp app, not WhatsApp Business. Log in with the same phone number you use for WhatsApp Business and verify it with the code WhatsApp sends you.Send messages to 2–3 contacts and wait for them to reply.
These need to be real two-way conversations with people who reply to you. Messages to yourself, or messages nobody answers, do not help. This activity is what lets Meta recognise the number as a genuine, active account.
4

Uninstall regular WhatsApp

Once you have exchanged messages with those contacts, uninstall the regular WhatsApp app. As before, remove the app only. Do not delete the account.
5

Reinstall WhatsApp Business

Install WhatsApp Business again and log in with the same phone number. When the app offers to restore your chat history, restore the backup you took in Step 1.Send messages to 2–3 contacts and receive replies from them, as you did in Step 3.
6

Try Embedded Signup again

Return to Eazybe and start Embedded Signup for the same number. The message about an already connected business partner should no longer appear.
If you need a reminder of each screen in the connection flow, follow Onboarding to Coex/API.
