Zapro × OnHand

Your WhatsApp keys, step by step

Your number (516) 588-6879 is approved. This is the last thing OnHand needs from you: five things to find in your Meta account and paste in below. Nothing to email, nothing to send anyone. Checkmarks save as you go.

Before you start: log in at business.facebook.com with the same personal Facebook account you used to create Zapro LLC. Keep this page open on one screen and Meta on the other — you'll copy something from Meta, paste it here, and go back for the next one. Nothing you paste here is shown to anyone; it goes straight into David's system.

1 · The permanent key

Open your system users.business.facebook.com/settings → Users → System users. If onhand-backend is already there, skip to the next line. If not: Add → name it onhand-backend → role Admin.

Give it the app and the WhatsApp account.With onhand-backend selected → Add assets → the Zapro OnHand app (full control) and the WhatsApp account.

Generate the key.Generate token → app: Zapro OnHand → expiration Never → tick exactly whatsapp_business_messaging and whatsapp_business_management → Generate → copy it now, it shows only once → paste it into box ① below.

2 · Two numbers from the WhatsApp page

Phone number ID → box ②.developers.facebook.com/apps → Zapro OnHand → left menu WhatsApp → API Setup → under "Send and receive messages", the Phone number ID. It's a long number, not a phone number.

WhatsApp Business Account ID → box ③.Same screen, just below it. Also a long number.

3 · Two things from the app's basic settings

App ID → box ④.Same app → left menu App settings → Basic → App ID at the top.

App secret → box ⑤.Same page → App secret → Show → re-enter your Facebook password if it asks → copy it.

4 · Send them

Paste each one into its box and press the button. OnHand checks all five with Meta before it saves anything — if one is wrong, it tells you which.

① The permanent key

② Phone number ID

③ WhatsApp Business Account ID

④ App ID

⑤ App secret

These five values go straight into OnHand's locked settings — they are never emailed, never texted, and never shown to anyone. Something not matching what you see on screen? Send a note above.
