A screenshot of a happy customer's WhatsApp message ("Received the order, quality is amazing 😍") converts better than almost any polished ad copy. It looks unscripted, personal and real.
That's exactly why regulators care about it. A chat screenshot in an ad is a testimonial, and a made-up one is a fake testimonial. It's now explicitly targeted in India, the US and the UK.
This is a practical overview, not legal advice. Rules change and details matter, so check with a lawyer for your specific campaign.
Quick Answer
- Real customer chat, with permission, not edited to change its meaning: generally fine. Blur personal details.
- Mockup clearly presented as illustrative (e.g. showing how your WhatsApp ordering works, labelled "illustrative"): generally fine.
- Invented chat presented as a real customer's words: a fake testimonial. Misleading advertising under ASCI and CCPA rules in India, banned under the US FTC's 2024 rule, and unlawful in the UK.
What the Rules Say
India: ASCI Code and the CCPA guidelines
- ASCI (Advertising Standards Council of India): the ASCI Code requires advertising claims to be truthful and not misleading, and testimonials to be genuine and representative of real experiences. ASCI's influencer guidelines also require paid endorsements to be clearly disclosed.
- CCPA (Central Consumer Protection Authority): the Guidelines for Prevention of Misleading Advertisements and Endorsements for Misleading Advertisements, 2022, issued under the Consumer Protection Act, 2019, say endorsements must reflect the genuine, reasonably current opinion of the person making them, based on actual use. Misleading ads can lead to penalties.
A fabricated "customer" WhatsApp chat fails both tests: nobody actually said it.
United States: FTC
- The FTC Endorsement Guides (revised 2023) require endorsements to reflect honest opinions and experiences, and material connections (payment, free products) to be disclosed.
- The FTC's Rule on the Use of Consumer Reviews and Testimonials (in force since October 2024) specifically prohibits fake reviews and testimonials, including ones attributed to people who don't exist or who didn't have the stated experience. Civil penalties are possible.
United Kingdom
The Digital Markets, Competition and Consumers Act 2024 made fake consumer reviews (and commissioning or publishing them) an automatically unfair commercial practice from April 2025. The CMA can enforce it directly. The CAP Code, enforced by the ASA, has long required testimonials to be genuine.
Using Chat Screenshots the Right Way
1. Real customer messages
- Ask permission before publishing, and keep a record of it.
- Blur names, numbers and photos, unless the customer explicitly agrees to be identified.
- Don't edit the words. Cropping for length is fine. Changing "good" to "amazing" is not.
- Don't cherry-pick misleadingly. One glowing chat among a hundred complaints implies a typical experience that isn't typical.
- Keep the original (the actual chat on your business phone), in case a regulator or customer questions it.
2. Illustrative mockups
Mockups are legitimate when they show how something works rather than claiming what a customer said:
- "Here's how ordering on WhatsApp works": a mockup of your ordering flow.
- "Get appointment reminders like this": a mockup of your reminder message.
- A product-demo slide showing your chatbot's replies.
Label them: "Illustrative conversation" or "Sample chat". Use obviously generic names, or your own brand as one side of the chat. Our chat screenshot templates are built for this kind of use. They show flows (order updates, reminders, support) rather than praise.
3. What to avoid entirely
- Invented chats full of praise from "customers".
- Screenshots that imply a celebrity, doctor or expert endorsed you when they didn't.
- "Before/after" results in a chat that no real customer reported.
- Edited real chats that change the meaning.
A Quick Checklist Before Publishing
- Is this a real customer's chat? Do I have their permission in writing?
- Have I removed or blurred personal details?
- Are the words exactly as the customer wrote them?
- If it's a mockup, is it labelled as illustrative, and does it show a flow rather than a fake opinion?
- Would a reasonable viewer think a real person said this? If yes, and they didn't, don't publish it.
Where Mockups Genuinely Help
Used honestly, chat mockups are useful marketing assets:
- Explainer creatives for WhatsApp ordering, booking or support.
- Landing-page visuals of your WhatsApp or Instagram automation.
- Pitch decks showing a customer journey (see how to mock up a WhatsApp chatbot for a pitch deck).
- Scam-awareness posts that protect your customers (see WhatsApp scam message examples).

Frequently Asked Questions
Is it illegal to use a fake WhatsApp screenshot in an ad? Presenting an invented chat as a real customer's testimonial is misleading advertising. In India it goes against the ASCI Code and the CCPA's 2022 guidelines, in the US the FTC's 2024 rule bans fake testimonials, and in the UK fake reviews are unlawful under the DMCC Act 2024.
Can I use a customer's WhatsApp message as a testimonial? Yes, with their permission, without changing the words, and with personal details blurred unless they agree to be named.
Is a mockup of my own WhatsApp ordering flow allowed? Generally yes, when it's clearly illustrative of how the service works and doesn't put invented praise in a customer's mouth. Label it as a sample.
Do influencers need to disclose paid chat-screenshot posts? Yes. Paid or gifted endorsements need a clear disclosure (e.g. #ad) under ASCI's influencer guidelines and the FTC's Endorsement Guides.
