Unable to connect existing WhatsApp number to LeadChain — Embedded Signup blocks re-adding registered number
Hello Zoho Support,
Details:
- WhatsApp Business Account (WABA) ID: XXXXXXXX
- Phone number: XXXXXXXX
- Phone Number ID: XXXXXXXXXX
- This number is already Connected on the WhatsApp Business Platform (Cloud API), with a High quality rating, and shows zero connected Partners, Apps, or System Users on the Meta Business side.
When I go through LeadChain's "Connect your WhatsApp Business Account" flow, the Facebook embedded signup correctly shows my existing Business Portfolio ("Leopard Orchid Safaris") and lets me select my existing WABA. However, on the next screen ("Add your WhatsApp phone number"), it only offers "Use a display name only" or "Add a new number" — there's no option to select the number that's already registered on this WABA.
When I enter the existing number (XXXXXXXX) under "Add a new number," I get this error:
"This number is registered to an existing WhatsApp account. To use this number, disconnect it from the existing account. Then, return to this page and re-enter the number."
I've confirmed on the Meta side that there is nothing to disconnect — no apps, partners, or system users are attached to this WABA or number. LeadChain itself also shows 0 chains connected in the Integrations tab, so there's no stale connection on your end either.
Could you please advise:
- Is there a way for LeadChain's embedded signup to select an already-registered existing number instead of requiring "Add a new number"?
- Alternatively, does LeadChain support connecting via a manually entered WhatsApp Business API access token and Phone Number ID, bypassing the embedded signup flow?
Thank you for your help.
