WhatsApp Autoresponder: Set Up Auto Replies Without Code

Customers message small businesses at all hours, and most of the time they ask the same handful of things: are you open, where are you, how much is it, can I book. A WhatsApp autoresponder answers those first messages the moment they arrive, even when nobody is holding the phone. This guide is written for owners and small teams, not developers. You will not touch code, and you do not need Meta's official WhatsApp Business API. You link your own WhatsApp number by scanning a QR code, then set up simple trigger-to-reply rules in a dashboard.

By the end you will know exactly what a WhatsApp auto reply is, how the trigger matching works, how to set one up step by step, and you will have ten ready-to-use templates you can paste in and edit. If you want to see where this sits alongside the rest of the platform first, the features overview is a good map, and you can create a free account to follow along.

What is a WhatsApp autoresponder?

A WhatsApp autoresponder is an automatic reply that goes out when an incoming message matches a rule you set. You decide the trigger, for example the word "hours" or "price", and you write the reply that should be sent back. When a customer sends a message that matches, the system answers instantly with your canned text. That is the whole idea: no typing, no waiting, no missed first impression.

This is sometimes called a WhatsApp auto reply, an away message, or a canned response. The WhatsApp Business app has a basic version built in: a single greeting message and a single away message tied to your business hours, described on the WhatsApp Business app page. A dedicated autoresponder goes further. Instead of one fixed sentence for everyone, you can set up many different replies, each triggered by a different keyword, so "price" gets your pricing answer and "address" gets your directions.

Keyword autoresponder versus AI replies

There are two very different ways to automate WhatsApp answers, and it helps to be clear about which one this article covers.

The keyword autoresponder is a simple, predictable rule engine. You define a trigger and a reply. If the message matches, your exact text is sent. Nothing is generated, nothing is guessed, and you know word for word what every customer will receive. It costs nothing to run per message, it works the same every time, and it is the right tool for the questions you can answer with a fixed script. That is what we set up here.

An AI reply, by contrast, reads the message and writes an original answer based on a brief you provide. It can handle vague or unexpected questions that a keyword could never catch, but it needs your own AI provider key and careful guardrails. If that is what you are after, read our companion guide to AI WhatsApp auto replies. Many businesses use both: keyword rules for the predictable questions and an AI catch-all for everything else. For the bigger picture of how automation fits your support, see our overview of WhatsApp automation.

Common uses for an auto reply

You do not need to automate everything. The best autoresponders cover a small set of high-frequency, low-risk messages. Here are the patterns almost every small business benefits from.

Use	What it does	When it helps most
Out-of-office / after-hours	Tells customers you are closed and when you reopen	Evenings, weekends, holidays
Greeting / acknowledgement	Confirms you received the message and will reply soon	Every first contact, so nobody feels ignored
FAQs	Answers repeat questions on hours, price, location, parking	All day, freeing staff from copy-pasting
Booking and orders	Sends your booking link or asks for the details you need	Peak enquiry times
Human handoff	Routes anything sensitive to a real person	Complaints, refunds, urgent issues

Notice the theme: automate the routine, escalate the rest. A good "we got your message" acknowledgement is often the single highest-value reply you can add, because it buys you time and reassures the customer that a human is coming. The use cases page has more examples mapped to different business types.

How trigger-to-reply matching works

Every autoresponder rule has three parts: a source (which linked WhatsApp account it listens on), a trigger (what the incoming message must match), and a reply (the text sent back). The interesting part is how the trigger is compared against the message. SharkSMS gives you five matching modes, from strict to flexible:

• Exact, case insensitive. The whole message must equal your trigger, ignoring capitals. "HOURS" and "hours" both match a trigger of "hours", but "what are your hours" does not.
• Exact, case sensitive. The whole message must match your trigger exactly, capitals included. Useful for codes or precise keywords.
• Contains the keywords. The most useful mode for real customers. You list one or more keywords separated by commas, and the reply fires if any of them appears as a whole word anywhere in the message. A trigger of "hours, open, opening, time" catches "what are your opening hours?" and "are you open now". Matching is case insensitive and respects word boundaries, so "open" will not accidentally trigger on "opener".
• Regular expression. For advanced pattern matching when you need it. Most owners never touch this one, and that is fine.
• None-matching (catch-all). A safety net that fires only when no keyword rule matched. This is where your "thanks, a team member will reply shortly" acknowledgement belongs, so every message gets some response.

The order matters and it is handled for you: keyword rules are checked first, and the catch-all only runs if none of them matched. That means you can layer specific answers on top of a general fallback without them fighting each other.

A few extra controls make the rules practical. Each reply has a priority setting, so an important message like an after-hours notice or a human handoff can jump ahead of the normal sending queue. There is a group option that decides whether a rule should also respond inside WhatsApp group chats or only to direct messages, which stops your business from auto-replying to every group it belongs to. And replies can include simple merge fields for dynamic values such as the current date and time, so a single after-hours message can always read correctly without editing.

Setting up a WhatsApp autoresponder, step by step

Here is the full path from a fresh account to a working auto reply. None of it involves code.

1. Create your account and open the dashboard. You can register in a couple of minutes.
2. Link your WhatsApp number. Add a WhatsApp account and scan the QR code with the phone that holds the number you use for customers. This links your existing WhatsApp or WhatsApp Business app account by QR, so you keep your own number and you do not need the official WhatsApp Business API.
3. Open Tools then Actions and create a new Auto-reply action. This is where every rule lives.
4. Choose your linked WhatsApp account as the source, so the rule listens on the right number.
5. Pick a match type from the five modes above. For most FAQ replies, choose "Contains the keywords".
6. Enter your trigger. For keyword mode, list the words a customer might use, separated by commas, for example hours, open, opening, time.
7. Write the reply exactly as you want it sent. Keep it short, friendly, and specific.
8. Set the priority and the group option, then save. Mark time-sensitive replies as priority; leave the group option so it only answers direct messages unless you genuinely want group replies.
9. Add a catch-all. Create one more rule with the "None-matching" type and a gentle acknowledgement, so nothing goes unanswered.
10. Test from another phone. Message the number with the exact keywords, with misspellings, and with something random, and confirm each reply reads well and the catch-all covers the rest.

That is it. Once the rules are saved, incoming messages are matched automatically and the replies go out on their own.

Ten ready-to-use auto-reply templates

Copy these, swap in your own details, and adjust the trigger keywords to how your customers actually write. Use "Contains the keywords" mode unless noted otherwise.

1. After-hours / out-of-office

Triggers: none needed, use the catch-all during closed hours, or keywords like open, hours.

Thanks for your message! We are currently closed and will reopen tomorrow at 9am. We will reply as soon as we are back. For anything urgent, please call us on 0123 456 789.

2. "We got your message" acknowledgement

Best set as the None-matching catch-all so it covers anything you did not plan for.

Thanks for reaching out! We have received your message and a team member will reply shortly, usually within a couple of hours during business hours.

3. Opening hours

Triggers: hours, open, opening, time, when

We are open Tuesday to Saturday, 9am to 6pm, and closed Sunday and Monday. Bank holidays may vary, so feel free to ask.

Of course, a real person will take it from here. We have flagged your message and someone from the team will reply personally very soon. Thank you for your patience.

Best practices: automate the routine, keep it human

An autoresponder is a helper, not a replacement for your team. A few habits keep it useful rather than annoying.

• Do not over-automate. Cover the predictable questions and leave judgement calls to people. A wall of robotic replies feels worse than a slightly slower human answer.
• Always offer a human handoff. Include a clear way to reach a person, and make sure complaints, refunds, and anything urgent route straight to someone who can help. The template above is a good default.
• Keep replies short and specific. One or two sentences, a link if useful, and a clear next step. Long auto replies get skimmed and ignored.
• Set the right expectation. If you say "we will reply within an hour", make that true during business hours. Broken promises erode trust faster than no promise at all.
• Review and refine monthly. Watch which questions still reach a human and add new keyword rules for the common ones. Fix outdated hours, prices, and links.
• Respect consent. Autoreplies answer people who message you first, which is exactly how it should be. Sending unsolicited promotional broadcasts is a separate activity and must follow WhatsApp's own Business Messaging Policy. Aggressive broadcasting from a linked personal number also risks WhatsApp limiting or banning the account, so keep automation focused on genuine replies. If in doubt, the WhatsApp Help Center explains the rules.

Frequently asked questions

Do I need the official WhatsApp Business API?

No. You link your own WhatsApp or WhatsApp Business app number by scanning a QR code, then build your rules in the dashboard. There is no Meta approval process and no per-message platform pricing to deal with.

Will it reply to every message?

Only if you add a catch-all. Keyword rules answer the messages that match them; a "None-matching" rule answers everything else. Set up both and nobody is left without a response.

Can one keyword trigger different replies?

Each rule maps a trigger to one reply. To cover different phrasings, list several keywords in one rule using "Contains the keywords" mode, for example price, cost, how much. For genuinely different questions, create separate rules.

What is the difference between this and AI replies?

The keyword autoresponder sends your exact, pre-written text when a trigger matches. It is predictable and free to run per message. AI replies generate original answers and need your own provider key. See our AI WhatsApp auto replies guide for that approach.

Does it work for SMS too?

Yes. The same auto-reply actions work on linked Android SMS gateway devices, so you can apply the same idea to text messages. WhatsApp suits back-and-forth conversations, while SMS is ideal for short confirmations and reminders.
