Simple REST API
Text, images, video, audio, documents, stickers, locations, contact cards, polls, replies, mentions and view-once — one endpoint.
Real-time webhooks
Incoming messages, delivery and read receipts, reactions, group events and calls, signed with your secret.
Bulk campaigns
Upload a list, personalise with {{name}}, vary wording automatically, schedule, and watch sent, delivered and read counts live.
Auto-replies
Answer “price”, “hours” or any keyword instantly, 24/7 — perfect alongside your own chatbot through the API.
Account protection
Human-like pacing, typing indicators, a warm-up for new numbers, duplicate and dead-number checks to keep your number healthy.
Groups & contacts
Create groups, add or remove members, get invite links, read contacts and check if a number is on WhatsApp.
Multiple numbers
Connect 1 to 25 WhatsApp numbers — sales, support and marketing — each with its own key and webhook.

Every message and webhook is logged. People who reply STOP are removed from your campaigns automatically.

What is a WhatsApp API gateway?
A WhatsApp API gateway connects your WhatsApp number to your own software, so your website, CRM, shop or server can send and receive WhatsApp messages through a simple REST API — order confirmations, one-time passwords, delivery updates, reminders and support replies — without anyone typing them by hand.
WApenda is a WhatsApp API gateway that works with the number you already have. Scan a QR code (or enter a pairing code) to link the number, copy your API key, and send your first message with one HTTP request. Incoming messages, delivery receipts and status changes arrive at your webhook in real time.
WhatsApp REST API for developers
Send text, images, documents, audio, video, locations and contacts; check if a number is on WhatsApp; manage groups; and receive events by webhook. Endpoints are compatible with the WaSender API, so existing integrations keep working — see the API documentation for PHP, Node.js, Python and cURL examples.
Bulk WhatsApp sender and campaigns
Upload a contact list and send personalised bulk WhatsApp campaigns with {{name}}-style variables, message variations (spintax), safe sending speeds and automatic STOP opt-outs — plus keyword auto-replies that answer customers around the clock.
WApenda vs. the official WhatsApp Business API
Meta’s WhatsApp Business (Cloud) API charges per conversation, requires business verification and approved message templates. WApenda instead links your existing WhatsApp or WhatsApp Business number through WhatsApp’s multi-device feature and is priced per number with unlimited messages — ideal for small and medium businesses, developers and agencies. Because it is not Meta’s official API, follow WhatsApp’s rules: message only people who agreed to hear from you and honour opt-outs.
WhatsApp API pricing
Plans start at $4.50 per month for one number, with unlimited messages, webhooks and campaigns, and you can try any plan for 3 days for $1. See WApenda pricing.
Frequently asked
What do I need to start?
A WhatsApp account on your phone (regular or WhatsApp Business) and a Tekservix account. You link WApenda like WhatsApp Web — scan a QR code, or type an 8-character pairing code. Your phone doesn’t need to stay online.
How do I pay?
From your Tekservix wallet. Top it up, then start the $1 trial or choose a plan. Plans renew automatically from your wallet; we email you before every renewal and you can turn auto-renewal off anytime.
What happens after the $1 trial?
After 3 days the trial continues on Starter ($4.50/month) if your wallet has the balance and auto-renewal is on. Otherwise your device pauses — it stays linked, and choosing a plan switches it back on.
Is it the official WhatsApp Business API?
No. WApenda links your number as a companion device (like WhatsApp Web), so there’s no Meta approval or per-message fee. That also means WhatsApp’s own rules apply: message people who expect to hear from you, and avoid cold bulk messaging. Numbers that spam can be banned by WhatsApp — our account protection helps, but can’t override WhatsApp’s policies.
Are messages really unlimited?
Yes — there’s no per-message price. To protect your number, account protection spaces messages out like a person would and ramps up new numbers over their first days. You can switch it off per device for high-volume, opted-in traffic.
Can I change plans?
Upgrades apply immediately — you pay only the difference for the rest of the current period. Downgrades take effect at your next renewal.
What isn’t allowed?
Spam, messaging people who didn’t agree to hear from you, scams, harassment and anything illegal. We suspend devices that break these rules. Campaigns ask you to confirm consent, and people who reply STOP are never messaged again by your campaigns.
