Who it's for

If you already write on WhatsApp, automate it.

Waya uses the line your business already has. You scan the QR from that phone and carry on with the same number printed on your cards.

Development teams

One POST and the message goes out. Your ERP already knows when the instalment is due; now it says so too.

REST API with a token

Collections and admin

You upload the list, write once, send to 2,000.

Bulk sending

Marketing and shops

A seasonal promotion to your whole base. It is ready in 5 minutes and goes out from your usual number.

A campaign in 5 minutes
A lawyer checking WhatsApp on her phone
The channel already exists

Your customer already writes to you on WhatsApp. Waya just stop doing it by hand.

Nobody has to learn a new app or download anything. The firm, the clinic or the shop carries on chatting where it always did; what changes is that the reminder, the document and the confirmation come out of the system rather than off someone's thumb.

  • The same line as always, the same number printed on your cards
  • The customer replies and the conversation carries on in the phone, as always
  • Your system fires the repetitive stuff; the important messages you write yourself

What's included

300 messages a month at no cost, and the same features as W5.

Only two numbers change between plans: how many devices you connect and how many messages you send a month.

Set-up by scanning the QR

You open WhatsApp on the company phone, go to linked devices and scan the code from the panel. The line is connected. No forms, no approvals and no change of number.

1 minute
300free/month

Bulk sending

Up to 2,000 messages per batch. You load the list and the system distributes it.

Multi-device

Sales, support and collections: one line per department, all in the same panel.

5 min

A campaign ready in five minutes

Little happens between sign-up and the first bulk send: you connect, paste the list and fire. There is no learning curve.

Individual sends

A one-off message to a single number, from the panel or from your system. Useful for the notice that is not a campaign.

API integration

It connects from any system that can make an HTTP request: your ERP, your shop, your invoicing system or a three-line script. See the example →

Bulk sending

One list, one message, one button.

You paste the numbers or upload the file, write the text with whichever fields you want personalised, and send. Waya distributes the batch and shows you live how many went out.

  • Up to 2,000 simultaneous messages per send
  • Personalise name, amount or date in every message
  • Attach a PDF, image or link in the same message
  • Choose which device each campaign goes out from
  • A report of sent, delivered and failed

Multi-device

Several numbers, one single panel.

Each department with its own line and its own history, all managed from the same account. When a device disconnects, the panel tells you and you link it again by scanning once more.

  • Up to 5 devices connected on the W5 plan
  • Live status of every line: connected or disconnected
  • Choose the sending device on every API call
  • A counter of messages used per device

Getting started

From sign-up to first message, in a minute.

We open the account for you

We set you up on the free W1 plan, no card. You log into the panel and your API token is already generated.

You scan the QR

You open WhatsApp on your company phone, go to linked devices and scan. The line is connected.

You send

A test message from the panel or a POST /v1/messages from your system. It goes out with a double tick.

Your number, your contacts and your conversations stay yours. We only move the messages. Read the documentation →
Use cases

An instalment falling due, an order on its way, a receipt issued. Who tells them?

All these cases are the same request. Your ERP, your shop, your invoicing system and the panel itself push through the same line; what changes is the text, the attachment and who receives it.

  • Four different systems, one single outbound number
  • You choose which device each message goes out from
  • The customer replies in the same conversation as always
ERPshop invoicing systempanel your line

Payment reminders

The notice goes out with the exact amount and date, 3 days before the due date.

Order confirmations

Your shop records the purchase and the customer gets their tracking number.

Document sent as a PDF

You issue the receipt and the PDF arrives on WhatsApp the same second. No email in between, no attachments lost to spam.

Campaigns

You segment the list and fire off the batch of 2,000.

System alerts

Low stock, a payment that did not come in, a job that finished: your server writes to the team.

Verification codes

A one-time code to the customer's number.

Integration

Send text, PDF, image and links with a POST.

The API is REST and authenticates with a token you generate in the panel. You send JSON, you get JSON. No SDK required.

  • Token authentication Bearer
  • Text, image, PDF document and links
  • Reply with id and status of the message
  • It works from PHP, Python, Node, n8n or cURL

From where you already work

If your system can do a POST, it is already integrated.

There is no required library and no intermediate server. The same endpoint responds identically from a PHP cron, an n8n flow, or a line of cURL pasted into the terminal.

Plans

The free plan does not expire. You move up when you send more.

Three plans for one company, with the same features in all three. No activation fee and no lock-in.

Calculator

How many messages do you send a month?

Move the slider and we will tell you which plan covers you. Count everything that leaves your line: reminders, documents, confirmations and campaigns.

If you do not know the number, look at how many sales you close a month and multiply by the notices you send on each.

Messages you send per month messages
Your plan Free, no card and no cut-off date
→ 5000" hidden> Ask for a price →

At that volume the free plan is enough: 300 messages a month and 1 device, no card and forever.

Above 5,000 messages a month, a tailored plan suits you better. And if you are going to spread that volume across several of your own clients, look at Waya White Label or write to us.

Prices already include tax. Those marked with * are charged in US dollars because that product is not sold in soles.

What people already sending with Waya say.

4.9/5 across 824 verified reviews

We connected the collections line on a Monday and by Tuesday the reminders were going out on their own. Arrears dropped without hiring anyone.

The integration took me one afternoon. It is a POST, nothing more. Now every receipt we issue reaches the customer as a PDF on WhatsApp.

I started on the free plan to try it and within a week I was paying for W3. The cost is trivial next to what I save.

Questions

What people ask us before connecting.

Do I need a new number?
No. Waya uses the WhatsApp line your company already has. You scan the QR from that phone and it is connected. If you prefer to keep things separate, you can connect a different number per department: the W5 plan allows up to 5 devices.
What happens if I go over the monthly messages?
Sending pauses until you move up a plan or the next cycle starts. You can change plan whenever you like and the allowance updates immediately, with nothing to migrate and no linked devices lost.
Is the free plan a trial or forever?
It is forever. W1 gives you 1 device and 300 messages a month at no cost and no card. Perfect for testing the integration before moving to a paid plan.
How do I authenticate against the API?
With a token you generate in the panel and send in the header Authorization: Bearer. You can rotate it whenever you like. The main endpoint is POST /v1/messages and replies with the id and the status of the message. See the example →
Can I send files and not just text?
Yes. You send text, images, PDF documents and links. The most common case in Peru is sending the electronic document as a PDF the moment it is issued.
Can I have several agents replying from here?
Waya is built for sending, not for handling replies. If you need a shared inbox where your team answers, assigns conversations and leaves internal notes, Waya's shared inbox is what you want. See the shared inbox →
Can I resell Waya to my clients?
Yes, with the Reseller plans. You offer the same API under your brand and your domain, with a panel for your clients and prices you set. See Waya White Label →
Am I tied into a contract or charged an activation fee?
Neither. The service is month to month, activation is free and you cancel from your client area whenever you like.
Is the price I see the price I pay?
Yes. The amounts on this page already include tax and are the same ones at checkout, in whichever currency you pick above. We convert nothing: every plan has its real price in soles, dollars and pesos.
