Connecting WhatsApp lets your Nexor agent talk to leads on WhatsApp. It takes about 5 minutes through Meta’s embedded signup.

​
Before you connect

You need a Facebook account. During signup you can create a Meta Business Portfolio and WhatsApp Business Account (WABA), or use ones you already have. If you already have them, make sure you have:
  • access to the right Meta Business Portfolio and WABA, with capacity for another number
  • complete business info in Meta (legal name, address, business phone, and a public HTTPS website)
  • no unresolved status, verification, billing, or payment prompts in WhatsApp account settings or WhatsApp phone numbers
Connecting a number doesn’t bypass Meta’s checks. Display-name review, business verification, WABA review, payment eligibility, template review, and country or account restrictions can still block production sending.

​
Start in Nexor

You connect a number from two places in Nexor:
  • From an agent: open the agent’s settings, go to the WhatsApp channel, and click Connect.
  • From Integrations → WhatsApp.
Either one opens the same flow: pick how you want to connect below, then Nexor hands off to Meta’s embedded signup.

​
Bring your own number (SIM)

​
If the popup doesn’t load

Disable ad blockers and privacy extensions, since they block Meta’s SDK. Try Chrome or Firefox if Safari isn’t working.
