Chat buttons (Zalo, Messenger, WhatsApp) and Zalo alerts

Zalo chat button on the page

In Page settings → Contact buttons & Pixels, fill in Zalo (phone or OA ID). A personal phone number works — no business Zalo OA needed. The page shows a floating Zalo button that opens a chat with you. The Zalo field is filled from the phone number you gave when creating the page — if you don't use Zalo, clear it and Trano won't fill it again.

Only want a Call button, no Zalo: fill in Phone number (Call button) in the same tab and leave Zalo empty. The Call button only shows on phones.

Messenger and WhatsApp chat buttons

Also in Page settings → Contact buttons & Pixels: the Messenger field takes your Facebook page link or username (e.g. facebook.com/sweetmobakery), the WhatsApp field takes your number with country code (e.g. +1 415 555 0123). The link visitors will open shows under the field — tap it once to be sure. Each filled field adds its button; buttons stack in the bottom-right corner.

Advanced: lead alerts via Zalo OA

Zalo only allows automated messages from a Zalo Official Account (OA) plus your own Zalo app. This is for owners who already have an OA + app, and it has limits: an OA access token only lasts about 1 day (when it expires you must paste a new one or alerts stop), and Zalo only delivers to people who interacted with the OA recently. For reliable alerts, use Telegram, email or Google Sheets. If you still want to connect your OA, Trano provides a free bridge built with Google Apps Script:

1. In Leads → Lead settings → Zalo OA (advanced), open the 5-minute guide and press Copy script.
2. Go to script.google.com → New project → paste the code.
3. Replace ACCESS_TOKEN (from developers.zalo.me) and the recipient's USER_ID.
4. Deploy → New deployment → Web app → Execute as: Me · Access: Anyone.
5. Copy the URL ending in /exec, paste it into the OA Notification URL field → Save → Send test.
