WhatsApp opt-in link and QR code

WhatsApp allows Marketing templates only to people who agreed to receive them. The easiest way to collect that agreement is to let customers ask for it: put an opt-in link or QR code on a poster, a receipt, your website or a social post. It opens a WhatsApp chat with your business number and a message already typed, such as SUBSCRIBE RIYADH-EXPO. When the customer presses send:

• they are marked Agreed for WhatsApp in Contacts, with the source WhatsApp opt-in link and their message (with the code) as the proof in Consent history (Consent and opt-out);
• they get your confirmation message in the same chat, free of charge (Messaging rules);
• a new customer appears in Contacts and the Inbox like any other chat.

Before you start

• A WhatsApp number connected in Accounts (/app/channels). Without one the page says "Connect a WhatsApp number first: the link opens a chat with it." and Go to Accounts opens Accounts.
• Anyone who can open Contacts can make a link (no task needed). It only opens a chat; it changes nothing until a customer sends the message.

Step by step

1. Open Engage → Contacts (/app/contacts) and press Opt-in link & QR at the top (/app/contacts/opt-in-link). 2. WhatsApp number: pick the number the chat should open with (the first one is chosen for you). 3. Keyword: pick the word the message starts with: SUBSCRIBE, START, YES OFFERS, اشتراك, اشترك, نعم للعروض and the other built-in words, plus the ones you added in Settings → Messaging rules → Opt-in keywords. Choose Arabic for an Arabic audience: the confirmation is sent in the keyword's language. 4. Where it is used (optional): a short code for this poster or page, such as RIYADH-EXPO or INSTAGRAM-BIO. English letters, digits, - and _, up to 24; spaces become -. It is added after the keyword and saved in each person's consent history, so you can see later where they came from. A wrong character shows "Use English letters, digits, - and _ only (up to 24)." 5. The right-hand side updates as you choose: the QR code, the Pre-filled message and the Link (for example https://wa.me/966114840728?text=SUBSCRIBE%20RIYADH-EXPO). 6. Use it: - Copy link copies the link ("Link copied") for your website, bio or a social post. - Download QR (SVG) saves the QR code as an SVG file, sharp at any size, for your designer or printer. - Print opens a page with "Scan to get our offers on WhatsApp", the QR code, the message and your number, and your browser's print window.

Good to know

• The customer can edit the message before sending. If they change the keyword, it is an ordinary message and nothing is recorded; if they delete only the code, they are still subscribed (source Replied with a keyword).
• Someone already subscribed who sends it again gets no second confirmation and no new history line.
• STOP always wins: a later STOP or Stop promotions ends marketing to them as usual.
• Test it yourself: scan the QR code with your own phone, send the message, then open your contact in Contacts and look at Consent history.

If something goes wrong

• "hello" is not one of this workspace's opt-in keywords (…) → pick a word from the Keyword list.
• "The code may use English letters, digits, - and _ (up to 24), e.g. RIYADH-EXPO." → remove spaces and other characters from the code.
• The customer sent the message but is not subscribed → check that the message was exactly the keyword (with or without the code), that it arrived on the WhatsApp number of this workspace, and that it appears in the Inbox.
