Get Started

This tutorial provides information on how to set up your WhatsApp Business API client, register your phone number, update your settings, and send a test message.

The process of getting started with this API can be divided into 3 main parts:

  1. Prepare assets — Before you start, you must set up the assets required to complete your API integration, including a WhatsApp Business Account.
  2. Install the WhatsApp Business API Client — Install your API client. Once your client is working, you can update your application settings.
  3. Start using the client — Register your phone number with an API call to /account and send a test message with a call to /messages.

Before You Start

In order to follow the steps in this tutorial, you must have been accepted into the WhatsApp Business API limited public preview or have signed up with one of our partnered Business Solution Providers for integration.

You need:

After you verify your business, your business is reviewed for compliance with the WhatsApp Terms of Service and WhatsApp Commerce Policy. This step is initiated automatically. You can check the status of business verification and business review in the Settings tab of your WhatsApp business account in Business Manager. Business verification will show as Verified and Account Status will show as Approved upon approvals.

Setting Up Your WhatsApp Account

Add a phone number and its display name to your WhatsApp business account. This will submit the display name for review.

If you want to change the display name, you can do so as many times as you wish until you complete registration, after which you must wait 30 days between any display name change requests.

When all reviews are completed, you can view and access your base64-encoded certificate, which is necessary for registering your WhatsApp Business API client. We encourage you to register with an approved display name to start integration, before making any further changes to a display name. You can change your display name at any point after integration.

Review Billing and Pricing Information

Once your business begins sending messages through the WhatsApp Business API, it's important to understand the billing process, such as how and when you're charged and how to view and pay your monthly invoice. For more information, see About Billing For Your WhatsApp Business Account. For pricing rules and cost per message, see our Pricing page.

Step 1: Install the WhatsApp Business API Client


At its core, the WhatsApp Business API client is based on Docker. See Client Architecture for information on each component.

Currently, the WhatsApp Business API client does not support Docker for Windows or Windows Subsystem for Linux. For development needs, using a Linux Virtual machine and running Docker within it is the recommended solution. For production workloads, we recommend using a Linux Server to avoid compatibility and performance issues.


The WhatsApp Business API client will run on any internet-connected machine that can run Docker for Linux, either in a virtual machine, or on Linux server. For more information see the FAQ. For instance, simple testing can be done on a laptop. For a production environment server, we recommend at least 250 GB SSD, 16 GB RAM, and 4 core CPU. HDD is not recommended as the I/O speeds will become bottlenecks under load.

In most cases, you should run the database on a separate physical server from the Coreapp and Webapp containers. The database server should only be a few milliseconds of latency away from the compute machine(s).


There are two ways to get started with the WhatsApp Business API:

  • On-Premises installation — You can set up the Docker containers on your own using the Installation guide. We recommend beginning with one of the Developer Setups to get familiar with the setup process and sending messages. This On-Premises solution can be used on your computer before migrating to a production environment.
  • Amazon Web Services (AWS): If you use AWS or would like a more standalone solution, see the AWS guide. The AWS solution sets up a whole WhatsApp Business API solution with backups, recovery, and more in an AWS cloud you manage and own.

Once the WhatsApp Business API client is running, you must be logged in as admin to perform the rest of the setup steps.

Update Your Settings

You can make changes to the Application Settings once the WhatsApp Business API client is working. However, you don't get access to your WhatsApp Business API client's different profile settings until registration is complete.

  • The Application Settings pertain to how the client works — callback settings, Webhooks, on-call pager, sent status, media download behavior, etc. Note: It is strongly recommended you set up a Webhook URL in order to receive notifications about incoming messages or errors.
  • The Business Profile Settings and Profile Settings cover your business's information such as address, email, website, industry, about information, and profile photo.

Step 2: Start Using the Client


Once you have the WhatsApp Business API client up and running, you can register your phone number by sending an API call to the account endpoint.

Send A Test Message

You can send test messages using the messages endpoint. First, check the status of the phone number you are using for testing. You will need to send your WhatsApp account a message from the test phone number to enable the Customer Service window, which allows you to send any type of message within the 24-hours window (See Cut-off Control for details). Then, send a text message to your test phone number. If the message arrives it means that the installation has been successful. If it doesn't arrive, check your Webhook for notifications that may indicate any problems.
