Xendit

Connect Xendit and your customers get a WhatsApp thank-you as soon as they pay a Xendit invoice. The message is sent for successful payments only. Xendit sends a verification token with every event, so only real payments from your account can send a message.

Before you start

A Xendit account.
An approved WhatsApp template for the message. See Create a WhatsApp template. Most templates are approved within 24 hours.
The customer's mobile number on each invoice. Pass it when you (or your website) create the invoice, or there is no number to send to.

Check where the phone number is

After the first real payment, open the Activity tab and click the event. What Xendit sent shows the exact data. If the customer's number is not where Send it to looks, ask your developer to add the payer's mobile number when creating the invoice, or use a Generic webhook, where you can pick any field.

Successful payments only

If Xendit sends an expired or failed invoice, no message goes out. Activity shows it as Skipped, Failed or cancelled payment. The message is only sent for successful ones.

The ₹ button in chats (for accounts in India) sends payment links through Razorpay, Cashfree, PayU or Zoho Payments. It does not use Xendit.

Pause: switch Active off on the right.
Disconnect: click the ⋮ button at the top right, then Disconnect, and confirm.
