How to block contacts

The Block Users API enables businesses block bad numbers from contacting the account.

When a WhatsApp user is blocked, the following happens:

• The user cannot contact the business or see that they are online.

• The business cannot message the user. If so, an error will occur.

Errors on the API occur per-number, since blocks might be successful on some numbers and not others. The Block Users API is synchronous.

To block a contact, you must have received a message from them within the last 24 hours.
