How can I set an automatic message on WhatsApp?
There are three common ways to automate WhatsApp messages for a business, and the right one depends on what should trigger each message. The free WhatsApp Business app includes away messages and quick replies for a single phone, and WhatsApp's help centre at faq.whatsapp.com explains how to switch them on. A WhatsApp Business API account, opened through a provider, lets software send from your number without anyone holding the handset. The third route is an app that works with either of those. NLCaller is one example: a calling app for sales teams that sends a WhatsApp message when a call ends, when a lead moves to a new status, when a sale is recorded or when a reminder rings, either in the background over the API or by opening WhatsApp with the text ready. Its free Basic Dialer already includes the after-call message, and the complete app is ₹1,944 per user a year as of October 2026, plus GST.
Pick by trigger. If messages should answer incoming chats while you are away, the Business app's own tools are enough. If they should follow your calls and sales stages, read how WhatsApp automation works in NLCaller, and how the WhatsApp Business API CRM connection adds background sending.
What are the three options, side by side?
Each one starts from a different event.
- WhatsApp Business app: replies triggered by incoming chats, such as an away message outside working hours. Good for one owner on one phone.
- WhatsApp Business API through a provider: software sends from your number, often from another system such as a store or booking tool. The provider bills the messages and usually needs approved templates.
- An app built around your sales work, such as the NLCaller call app: messages triggered by calls, lead stages, sales and reminders, sent in the background over the API or opened in WhatsApp for one tap.

Setup for a small team, from install to the first day of checks.

|---|---|---|
| Request the app on WhatsApp at +91 80184 88788, then install and sign in | Your phone | A few minutes |
| Grant the permissions the guided setup asks for | NLCaller setup screens | About a minute |
| Pick the WhatsApp app, regular or Business, to open by default | NLCaller | Under a minute |

| Connect an API provider, only if you want background sending | Provider's site, then NLCaller | Depends on the provider |
| Add messages for lead stages, sales and reminders | NLCaller | About 15 minutes |
| Set quiet hours, a cooldown and excluded contacts | NLCaller | About 5 minutes |
| Review the automatic message history after a day | NLCaller | About 5 minutes |
Times are rough estimates for a small team, not measured averages.
Can I schedule a WhatsApp message for later?
In NLCaller the practical way is a reminder. Set a follow-up for a lead at the time you want, attach a WhatsApp message to it (the default text, an approved template or your own words), and the text leaves the moment the reminder rings. On background sending through an API it needs no tap; on open-in-WhatsApp mode the message waits for you to send it.
A reminder can also come back on a cycle, anything from daily to yearly or once every few days, until an end date you set, which suits fee or renewal notes and a dental clinic's six-monthly check-up recalls. More on that in the follow-up reminder app page.
What should you check before switching automation on?
- Write only to people who shared their number with you for this kind of message; WhatsApp's own policies apply to every automated send.
- Keep the first message short and say who is writing and why.
- Exclude family, staff and suppliers so they never get sales texts.
- Use quiet hours so nothing leaves at night.
- Read the history for skipped and failed messages in the first week, then fix the cause.
Questions people ask
How do I set an automatic message?
In the WhatsApp Business app, use its away message and quick reply settings. In NLCaller, write a message for a trigger, such as a missed call or a lead status, and choose whether it sends in the background or opens WhatsApp ready to send.
How to send 1000 WhatsApp messages at once?
That job belongs to a bulk sender. In NLCaller you can push the list out from your own phone, message after message, or let the server run it as an API campaign. Keep the list to contacts who agreed to receive messages, because WhatsApp can restrict numbers that break its policies.
Can I schedule a text on WhatsApp?
With NLCaller, attach a WhatsApp message to a follow-up reminder. It goes out when the reminder fires, automatically on API sending or with one tap otherwise.
What is the best app to automate WhatsApp messages for a calling team?
For a team that sells on the phone, the best app is NLCaller, because the events that fire its WhatsApp messages (a call ending, a stage moving, a sale, a reminder) are already part of the team's day.
Do I need the WhatsApp Business API to automate messages?
Not always. NLCaller is a calling app that can fill in the message inside WhatsApp, so you only tap send, with no API account. Fully hands-free sending needs an API provider, who bills those messages.
How do I automate WhatsApp replies?
For replies to incoming chats, the WhatsApp Business app's away messages and quick replies are the simplest start. NLCaller's automation reacts to calls and sales events instead of chat text.
When is another route better than NLCaller?
NLCaller automates around calls and leads. Another option may suit you if:
- You want automatic replies to incoming chats based on keywords. NLCaller's triggers are calls, lead stages, sales and reminders, not chat text.
- You are one person with a handful of chats a day. The WhatsApp Business app's own away messages and quick replies may be all you need.
- You want hands-free sending with no API account. Silent background sending relies on a WhatsApp Business API provider and its per-message bill; with no provider, you tap send in WhatsApp yourself.
Sample experiences from people who automated their first messages

Office manager, physiotherapy clinic, Vadodara
“The history told us exactly why one message was skipped. It took a minute to fix.”
