To connect WhatsApp, open Settings > Connections > WhatsApp and select Connect WhatsApp when it is available. In the earlier look, open Settings > Channels > WhatsApp & channels and select Connect WhatsApp. This launches Meta's embedded signup flow in a popup: sign in with the Facebook account managing your business, pick or create a WhatsApp Business Account, and choose a phone number. After you finish Meta's steps, return to Engage and wait for its connection result. Closing the popup alone does not confirm that your number connected.
One-click connect depends on a configuration Meta approves per app. If it is pending, the WhatsApp page shows Setup pending instead of the connect button; your Stravax onboarding contact can connect the number for you in the meantime.
Meta bills your WhatsApp message delivery directly to the payment method on file in your Meta Business Manager. Your Stravax Engage prepaid wallet covers platform usage only, not the WhatsApp message charges themselves.
Once connected, the WhatsApp page in Settings > Connections shows your number, status, messaging limit and quality rating. In the earlier look these details are in Settings > Channels > WhatsApp & channels. Broadcast sending is paced against the number's limits, but individual messages can still fail or be deferred. Keep an eye on quality too: if Meta rates the number RED, broadcasts freeze automatically to protect it.
Facebook and Instagram connect in the new look where the option is available. See Connect Facebook and Instagram. After the Facebook connection change, they cannot be connected or reconnected in the earlier look; contact support if needed.
