2Chat

WhatsApp Coexistence is a Meta feature that allows a business to use the same phone number simultaneously in two channels: the WhatsApp Business App (mobile or desktop) and the WhatsApp Business API (WABA) via 2Chat. Messages sent from either channel are synchronized, so your team can work in 2Chat while the business app remains active on the same number.

Coexistence is activated through Meta's Embedded Signup flow. During the connection process, Meta connects your number to the WhatsApp Cloud API while keeping the WhatsApp Business App active on your phone. Your message history is preserved, and you can continue using the app and 2Chat at the same time. The channel will appear as Connected in 2Chat immediately, without requiring manual verification.

Go to Channels in the main menu and click Add channel → WhatsApp.

When the wizard asks "Do you already use WhatsApp Business on your phone?", select Yes.

Click Continue to Meta. The Meta Embedded Signup window will open.

Log in with your Meta Business account and select the number you want to connect.

Complete the flow. Your channel will appear as Connected in 2Chat automatically.

1. Go to Channels in the main menu and click Add channel → WhatsApp.
2. When the wizard asks "Do you already use WhatsApp Business on your phone?", select Yes.
3. Click Continue to Meta. The Meta Embedded Signup window will open.
4. Log in with your Meta Business account and select the number you want to connect.
5. Complete the flow. Your channel will appear as Connected in 2Chat automatically.

You must open the WhatsApp Business App on your phone at least once every 13 days to keep the coexistence connection active. If you don't, Meta will disconnect the number from the API. Opening the app again will restore it.

Without Meta Business verification: up to 250 templates and 250 messages/day

With Meta Business verification: up to 6,000 templates

Coexistence channels are labeled in the 2Chat channel list. If your channel was connected while the WhatsApp Business App was still active on the same number, it is operating in coexistence mode.

WhatsApp calls are not supported on coexistence channels. In coexistence mode, your number is connected to the Cloud API while the WhatsApp Business App remains active — this is a shared connection. Calls require your number to be exclusively on the Cloud API. To enable calling, you would need to remove the number from the WhatsApp Business App and reconnect it in 2Chat as a standard (non-coexistence) channel. This is a separate, manual process.

If you have any questions please feel free to reach out to support.

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.
