Can I block a customer who keeps placing fake orders on WhatsApp?
Updated 1 October 2026
On the API, yes. You can block a user who contacted your business in the last 24 hours. A blocked user cannot contact you.
- Limits: up to 1,000 users per request and 64,000 in total on the block list.
- Effect: the user cannot contact you or see that you are online, and you cannot message them.
- Undo: a DELETE request to the same endpoint unblocks users and restores communication.
- Blocking on the Business app was not checked. Ask for online payment or a deposit before cooking.
Make fake orders cost the sender
Customers can pay online at checkout on your own payment account, so a fake order costs the sender money. Every order sits in your dashboard with the customer's details.
