WuzAPI Hosting Live In 5 Minutes

Deploy WuzAPI hosting and run your own self-hosted WhatsApp REST API, with multiple sessions and signed webhooks for your apps. xCloud runs the pinned WuzAPI 1.0.9 image with PostgreSQL 16 behind HTTPS on your domain, generates the admin token and the encryption and HMAC keys, and keeps users, sessions and messages on persistent storage. It is unofficial software, so read the terms warning before use.

What is WuzAPI?

WuzAPI is an implementation of the whatsmeow library as a simple RESTful API service with multiple device support and concurrent sessions. Upstream says whatsmeow does not use Puppeteer on headless Chrome or an Android emulator, but talks to WhatsApp's WebSocket servers directly, so it needs much less memory and CPU. Endpoints cover sessions, messages, users, chat, groups and webhooks with optional HMAC signing. Self-hosted WuzAPI is MIT-licensed. Upstream warns that violating WhatsApp's Terms of Service can get a number banned.

On xCloud it is WuzAPI 1.0.9 with PostgreSQL 16, both pinned by digest, on the wuzapi_db volume. RabbitMQ is optional and not included. You sign in to the dashboard's Admin Mode with the generated admin token, then create a user instance per WhatsApp number. Give every user a non-empty token.

WuzAPI Hosting In 3 Easy Steps

Running a WhatsApp REST API yourself means a Docker host, PostgreSQL, a domain, a certificate and a set of generated keys to get right. This is the same API without building any of it.

  1. Step 01

    Sign Up

    Create your xCloud account and pick WuzAPI from the OneClick catalog. Just choose a domain and server — no other fields.

  2. Step 02

    We Deploy It For You

    One click. We bring up the pinned WuzAPI 1.0.9 image with PostgreSQL 16 on a private network, published over HTTPS on your domain.

  3. Step 03

    Enable Admin Mode And Pair A Number

    Open /dashboard, enable Admin Mode with the admin token, create a user with a non-empty token and scan the QR code to pair WhatsApp.

Everything WuzAPI Does, On Your Own Server

WuzAPI runs in full here — one REST API for your WhatsApp numbers, on infrastructure you control.

  • Every Message Type

    Send text, image, audio, document, video, sticker, location, contact, template and poll messages through REST endpoints.

  • Multiple Sessions

    Run several WhatsApp multi-device sessions on one install, each with its own user token and webhook.

  • Signed Webhooks

    Receive incoming events and messages, with optional HMAC-SHA256 signatures (x-hmac-signature) to verify each payload.

  • Groups, Contacts And Chats

    Create and manage groups, check whether numbers are on WhatsApp, set presence, mark messages read and react.

  • Lightweight WhatsApp Connection

    whatsmeow talks directly to WhatsApp's WebSocket servers, with no headless browser or Android emulator.

  • Survives A Restart

    Users, WhatsApp sessions and the message store live in PostgreSQL; a user and its token survived a restart of both containers in QA.

Everything You Need To Run Your WhatsApp API 24/7

  • React to incoming messages

    Register a webhook and receive events and messages as they arrive, verified with an HMAC signature.

  • Run several numbers side by side

    Create one user instance per number, each paired separately with its own token and webhook.

  • Check numbers and manage groups

    Look up whether phone numbers have WhatsApp and create or manage groups through the API.

WuzAPI vs Alternatives

WhatsApp Business API
Upstream recommends contacting a WhatsApp global solution provider and the official WhatsApp Business API for commercial messaging. WuzAPI is an unofficial client for your own use, with the ban risk upstream describes.
Evolution API
Evolution API has its own OneClick page as another self-hosted WhatsApp gateway. WuzAPI is a small Go service built directly on whatsmeow, with PostgreSQL storage.
OpenWA
OpenWA has its own OneClick page as another WhatsApp automation option. WuzAPI avoids headless Chrome and emulators by talking to WhatsApp's WebSocket servers directly.
Browser-driven gateways
Gateways that drive headless Chrome or an emulator use far more memory and CPU, according to upstream. WuzAPI uses whatsmeow instead, though the same terms warning applies.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!
Brian Geovanny
I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.
Dumitru Butucel
xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.
Waqar Ahmed
Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍
Rahul Singh
So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.
Massimo Villa
Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.
Gerson El
I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.
Tony Lewis
I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.
Jared McDowell
I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.
Dan Spinoza
Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

Can you self-host WuzAPI with Docker?

Yes. Upstream lists Docker as an optional way to run it, and this template is WuzAPI Docker hosting already assembled: the 1.0.9 image and PostgreSQL 16 pinned by digest, one database volume, generated keys and HTTPS. It is your own WuzAPI cloud WhatsApp API service.

How much RAM does WuzAPI need?

WuzAPI lists 256 MB memory, 1 vCPU and 4 GB storage; measured peak memory on QA was about 45 MiB. Our entry plan is 6 GB, far beyond what this service needs. PostgreSQL 16 runs beside it in a second container and shares that memory.

Is WuzAPI free?

Yes, MIT licensing carries no software fee. Billing covers the dedicated Cloud VPS, cancellable any time. WhatsApp's own terms still govern how you may use the connected number. Remember that connecting a number to an unofficial client is your own risk, as upstream warns.

Is WuzAPI an official WhatsApp product?

No. It is an unofficial client. Upstream warns that using it in violation of WhatsApp's Terms of Service, such as sending spam, can get a number banned, and recommends the official WhatsApp Business API for commercial messaging. Use it at your own risk.

How do I sign in to WuzAPI?

Use the admin token from your installation credentials in the dashboard's Admin Mode, or send it as the Authorization header on /admin/* requests. Each WhatsApp instance then has its own user token, which you create from the admin area.

Can I connect more than one WhatsApp number to WuzAPI?

Yes. Upstream describes multiple device support and concurrent sessions. Create one user instance per number; each one pairs separately by scanning a QR code and has its own token and webhook, so one number's events do not mix with another's.

Which endpoints does WuzAPI offer?

Upstream lists session, messages, users, chat, groups, webhooks and HMAC configuration endpoints. You can send text, images, audio, documents, video, stickers, locations, contacts and polls, set presence, send reactions and manage groups, all over REST with a token.

Can I create a WuzAPI user without a token?

Give every user a non-empty token. In WuzAPI 1.0.9, a user created with an empty token lets any request without a token authenticate as that user. Treat tokens as secrets, and do not paste them into tickets or screenshots.

Can I change the WuzAPI encryption or HMAC keys later?

No, not casually. They are read on every start, and rotating them can make previously encrypted data unreadable. The database password applies only when PostgreSQL first creates its volume, so rotate it inside PostgreSQL first, then update the matching value and redeploy.

How do I back up WuzAPI?

Back up the wuzapi_db volume, preferably with a PostgreSQL dump from pg_dump, plus your admin token, encryption key and HMAC key. Without the keys, stored data cannot be read after a restore. Test a restore on a spare install, and keep the copies private.

Backups in xCloud

How do I upgrade WuzAPI?

The install stays on pinned 1.0.9 and PostgreSQL 16 until you adopt a newer template version. Back up the database and keys, inspect upstream's release notes, then redeploy and check the dashboard and a paired session. Nothing upgrades automatically.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
