This connects YOUR OWN Paynow merchant account, so payments from your WhatsApp customers land directly in your account - AutoWhats never holds or moves this money.
If you don't already have one, register as a merchant on Paynow. Approval can take a day or two, since Paynow verifies businesses before granting API access.
Open PaynowOnce logged in to your merchant dashboard, go to Integrations and either use your default integration or create a new one for AutoWhats. Each integration has an Integration ID (not sensitive - it just identifies which of your integrations made the request) and an Integration Key (sensitive - it signs every request as coming from you, keep it secret).
Go to Settings → Paynow in AutoWhats, enter the Integration ID and Integration Key from step 2, and Save. AutoWhats encrypts the key at rest and never displays it back to you.
Start a conversation with your own WhatsApp bot and ask about buying something that triggers a payment. You should receive a real Paynow checkout link, and the payment should show up in both your Paynow merchant dashboard and Paynow's own transaction history.
