A WhatsApp link looks simple, but small mistakes can stop it from opening, send people to the wrong number or remove the message. For a business, that means lost conversations.
Wrong phone number format
The number must include the country code and should contain digits only. Do not use +, spaces, dashes or parentheses. Clean the number before creating the link.
Missing country code
WhatsApp needs the country code to identify the number. Without it, the link may fail or point to the wrong destination. Always verify this before publishing.
Message not encoded
Messages with spaces, symbols or accented characters need URL-safe formatting. If you write the full link manually, the message can break. WPLink handles this automatically.
Message is too long
The pre-filled message should start the conversation. It should not feel like a long form. Use a short sentence that the customer is comfortable sending.
No testing before publishing
Open the link on mobile and desktop. Confirm that the chat opens, the number is correct and the message appears as expected. If you are printing a QR code, test it before production.
Avoiding these mistakes takes less than a minute and protects your best contact points.
