HOW IT WORKS

One real business's story on Sendio: the post draws the question, the question lands in your inbox, and the sale closes right there. No app-hopping.

01

You publish a post

Almacén Devoto schedules the photo of its new pesto batch. The post goes out on its own, on the day and time you picked.

02

They message you about it

Valentina sees it and asks about stock. The conversation lands in your inbox next to every other channel, full history included.

03

You reply — or they call

You answer from the same inbox. And if Valentina would rather call, the WhatsApp call rings right there and you pick it up in one click.

MESSAGING — LIVE

Real messaging: you start the conversation — no chat caps, no entry fees.

Every conversation lands in the same inbox with its full history, whichever app they message you on. Your team replies from one place and the customer gets the answer in the app they already use.

WhatsAppLiveTelegramLiveDiscordLive

Three different channels, one inbox: every conversation arrives wearing its channel's color.

SOCIAL — EARLY ACCESS

Upload the video, photo or carousel, write the caption and pick when it goes out: the post publishes itself. TikTok publishes today in early access, posting to your own account until TikTok's app audit clears. Instagram and Facebook Pages are under construction.

Social plans start at $0 and can be activated from the dashboard today.

CALLING — WHATSAPP

Your customer taps the call button in WhatsApp and the call rings in your dashboard, right next to their messages. Answer it, decline it or let it go: every call is logged with its duration.

No fine print.

No markup on Meta's rates. WhatsApp conversations are billed by Meta at Meta's price, straight to your account. We add no margin.

No active-contact fees. You pay for your plan, not for every person who messages you.

No surprise add-ons. Everything your plan includes is on the table — nothing sold separately later.

MercadoPago, ARS, crypto — pay however you can.

Pick the method at checkout and switch any time.

StripeMercadoPagoBitcoin

Cancel in one click. From the dashboard — transparent billing, no email-to-cancel traps.

FOR DEVELOPERS

The dashboard and the API are the same platform: everything you saw above can be done over REST. Signed webhooks, safe retries with Idempotency-Key, realtime over SSE — pure HTTP, no SDK to install.

  1. 01

    Create your API key

    Sign up with email + OTP. The Default Token shows up pinned on the dashboard — no settings-page detour.

  2. 02

    Paste the curl

    POST /api/v1/messages/send/text with channelId and payload. The window next door is copy-paste.

  3. 03

    Receive the webhook

    message.received arrives signed (X-WA-API-Signature, HMAC-SHA256) the moment the channel confirms.

FAQ

What is Sendio?
One inbox for every customer message. Official WhatsApp, Telegram and Discord land in the same place, with full history, and your team replies from there — no code, no app-hopping. You also publish to your socials (the Social module) and take WhatsApp calls, all from the same dashboard. And if your team is technical, the same thing is drivable via API.
What happens to the WhatsApp number my business already uses?
It stays yours — the number, your contacts and your Meta account don't change hands. When you connect WhatsApp you choose: use a new number or migrate the one you already have. The one thing to know: a number connected to Meta's official platform stops working in the phone's WhatsApp app — from that point on, conversations are handled from Sendio, with history, your team and calls in one place. Your customers won't notice a thing: they keep messaging the same number as always. And if you ever want to go back to the app, the migration is reversible. Many businesses try with a new number first and migrate their main one once they're convinced.
How fast can I send my first message?
Under 5 minutes. Sign up with your email, connect WhatsApp or Telegram from the dashboard in a couple of clicks, and you can start replying to customers — no code involved. Technical team? The cURL command and your token are right there too, ready for the API.
Can I cancel anytime?
Yes. From the dashboard, one click and one confirmation — no emails, no talking to support. Cancellation takes effect at the end of the period you already paid for.
Do I need my own Meta app?
No. Sendio is a verified Meta Tech Provider: you connect your WhatsApp number via Embedded Signup from the dashboard — no app to create, no App Review to pass yourself, no Business Manager work beyond authorizing.
What do WhatsApp calls cost?
The inbound call (your customer initiates it) has no Meta charge. Professional ($229) includes 100 min/month, then $0.02/min; Scale ($699) includes 500 min, then $0.01/min. You answer, decline or end every call from the dashboard — and if your team is technical, it's all drivable via API too, with the call.received event on the same webhook.
What happens if I exceed my plan's message quota?
Depends on the plan. On Free the limit is hard: once you hit 500 messages/month, sends are rejected and you're not billed anything. On paid plans, overage is billed at your own plan's per-message rate — from $0.002 on Developer down to $0.0008 on Scale. The usage counter lives in the dashboard.
Do you have real support or just an email address?
You text the founder directly on WhatsApp. Replies in your language, 4 business hours. No 'ticket #123', no 'specialized team', no chatbot. If Sendio breaks your production, we want to know in minutes, not after 3 emails.
Which payment methods can I use?
Stripe (international cards), MercadoPago (in Argentine pesos) or Bitcoin. You pick the method when subscribing and can switch it any time from Billing.
What is Sendio Social and what's available today?
The platform's second module: publish video, photo or carousel and pick when it goes out, from the same dashboard and the same account as Messaging. It's in early access today: TikTok already publishes (limited to posts on your own account until TikTok's app audit clears); Instagram and Facebook Pages are under construction. Social plans start at $0 and can be activated today. For technical teams: POST /api/v1/posts/publish, with scheduledAt for scheduling.
Can I activate Messaging only, or Social only?
Yes — they're independent modules on the same account and the same dashboard. Activate one today and add the other whenever, no migration. The bundle (both modules at a 15-20% discount) is coming soon. And if your team is technical: they share the same API key too.
Are webhooks signed?
Every webhook ships with X-WA-API-Signature (HMAC-SHA256) plus X-WA-API-Event and X-WA-API-Timestamp for replay protection. The docs include the verification snippet for each language.
