WhatsAPI: Chat Without Saving

Need to message someone once and never again? Stop filling your address book with one-off numbers. WhatsAPI opens a WhatsApp chat with any phone number in the world without saving it as a contact first. Pick the country, type the number, write your message, and tap send. That's it. WHAT YOU CAN DO • Message any number instantly Type or paste a number, choose a country from the list, and open the chat straight in WhatsApp. Nothing is added to your contacts. • 241 countries, always the right prefix Pick your country once and it is remembered. The dial code is added for you, the number is formatted as you type, and a bad number is flagged before you send. • WhatsApp or WhatsApp Business Switch between the two apps with one tap. Whichever you use, the chat opens there. • Message templates Four ready-made openers are built in, and you can save your own. Tap a template to drop it into the message box: perfect for sellers, freelancers and anyone who writes the same first line ten times a day. • Share a wa.me link Copy the link to your clipboard or send it to any app. Put it in your bio, your email signature, your invoices or your online store, and customers can start a chat with a single tap. • QR codes Turn any number into a scannable QR code and share it as an image. Print it on a flyer, a menu, a receipt or a shop window; a phone camera opens the chat. • Pick from your contacts Already have the person saved? Grab the number straight from the contact picker. No contacts permission is requested — the system picker hands over just the one number you choose. • Recent chats Every number you open is kept in a short local list with the message you sent. Tap an entry to load it again, tap the bin to drop one, or clear the whole list. • Share-to-app support Share a number or a piece of text from any other app into WhatsAPI and the fields are filled in for you. • Light and dark themes A clean Material Design interface that follows your system theme, edge to edge. • 11 languages English, Spanish, Portuguese, French, German, Italian, Russian, Arabic, Japanese, Korean and Chinese. PRIVACY Your data stays on your phone. Numbers, messages, templates and history are stored locally and are never uploaded to us. There is no account and no sign-up. WhatsAPI does not read your messages and cannot see your WhatsApp chats — it only builds a standard wa.me link and hands it to WhatsApp. The app is free and is funded by a banner ad served by Google AdMob, which may use your device's advertising identifier. That is the only third-party service in the app. WHO IT IS FOR Sellers on marketplaces, freelancers, delivery drivers, real-estate agents, support teams, shop owners, and anyone who has ever saved a contact just to send one message. REQUIREMENTS WhatsApp or WhatsApp Business must be installed to open a chat. If neither is, you can still copy or share the link and open it in a browser. WhatsAPI is an independent app. It is not affiliated with, endorsed by or connected to WhatsApp LLC or Meta Platforms, Inc. WhatsApp is a trademark of its owner.
