Every WhatsApp account is a phone number. The phone number that you intend to use with WhatsApp must be clean, that is, with no previous registration or affiliation with WhatsApp. There are 3 types of eligible phone numbers for this product:
The Business Manager has a phone number validity checker that you can run through to ensure a number is valid for WhatsApp Business API use.
For more detailed information on picking and registering a phone number, see the Phone Number guide.
You must also define the Verified Name for your selected number will have on WhatsApp.
The Verified Name can be a maximum of 256 characters and should not contain emoji or any variation of the word "WhatsApp".
For more information on setting up a Verified Name, see the Verified Name guide.
At its core, the WhatsApp Business API Client is based on Docker. Requirements depend on your load and situation. The WhatsApp Business API Client will run on any internet-connected machine that runs Docker. 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. You have two options:
With the client up, follow the registration steps. We recommend using our Postman collection to set a password and acquire the authentication token.See steps for RegistrationLearn about Postman Collection
After your setup is complete, it is time to test your installation. First, check the contact of your personal WhatsApp phone number.Checking Contacts
Before you can send your first test message with the WhatsApp Business API, you will need to send your WhatsApp Account a message by adding it to your personal phone's address book. This enables 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 personal WhatsApp number. If the message arrives it means that the installation has been succesful.Sending Text Messages
Optionally, you can download the WADebug tool to ensure that your Business API client is set up properly.
Control different settings of your WhatsApp Account including the Business Profile, profile picture, about, and much more.Manage Settings
Now that you have a working WhatsApp Business API client and have set the settings, create a backup. This allows you to restore everything you have just done on another machine without having to go through registration again. Make sure to keep your password in a secure place.Creating a Backup
You can also set up Webhooks so you can process incoming messages from people who respond to you on WhatsApp. These Webhooks process incoming text, location, media such as pictures and documents, and the status of the messages you've sent. We've prepared a code sample so that you can test this with a couple of clicks.
If the Webhook URL is not set, then callbacks will be dropped. Callbacks are an important channel to deliver, both timely notifications as well as out-of-band errors, and it is thus highly recommended to configure the Webhook URL endpoint.Setting up WebhooksProcessing WebhooksWebhooks Test App
Sending and receiving text messages is just the beginning! You can also send images and other media files.Sending Media
You can set up Message Templates that are standard messages you may want to send to your customers. The benefits of Message Templates versus plain text messages are many and will continue to grow. To highlight just one, when sending a message to a contact for the first time, WhatsApp displays buttons to mark the conversation as spam or block the number. With Message Templates, we know already that the template is a valid one, so these buttons won't show if your business is verified, allowing for a better user experience.Sending Message Templates
