● The WhatsApp Cloud API allows small and medium businesses to communicate
with their customers at scale.
● Using the API, businesses can build systems connecting thousands of customers
with agents or bots, enabling programmatic and manual communication.
● Additionally, you can integrate the API with numerous backend systems, such as
CRM and marketing platforms.
● Businesses looking to use the API have two hosting options: On-Premises and
Cloud API.

all customer queries.

chatbot, which are not available through the WhatsApp Cloud API. These
include

Message Templates
● WhatsApp message templates are specific message formats that businesses use
to send out notifications or customer care messages to people that have opted in
to notifications. Messages can include appointment reminders, shipping
information, issue resolution, or payment updates.
Currently, you can send the following template types:
● Text-based message templates
● Media-based message templates
● Interactive message templates include interactive buttons
• Call-to-Action — This allows your customer to call a phone number and visit a
website.
• Quick Reply — This allows your customer to return a simple text message.
These buttons can be attached to text messages or media messages. Once your
interactive message templates have been created and approved, you can use them in
notification messages as well as customer service/care messages. 16

Features, Pricing & Use Cases

18.
Features
Encryption
● With the Cloud API, every WhatsApp message continues to be protected by Signal
protocol encryption that secures messages before they leave the device. This
means messages with a WhatsApp business account are securely delivered to the
destination chosen by each business.
● The Cloud API uses industry-standard encryption techniques to protect data in
transit and at rest. The API uses Graph API for sending messages and Webhooks
for receiving events, and both operate over industry standard HTTPS, protected by
TLS.
Scaling
● Within Meta's infrastructure, the Cloud API automatically scales and adjusts to
handle your workload, within your rate limit (messaging volume and number of
WhatsApp business accounts). 18

Use Cases

WhatsApp Business Platform conversations fall into two categories that are priced differently:
● User-initiated: A conversation that initiates in response to a user message. Whenever a
business replies to a user within the 24-hour customer service window, that message will be
associated with a user-initiated conversation. Businesses can send free-form messages within
this 24 hour customer service window.
● Business-initiated: A conversation that initiates from a business sending a user a message
outside the 24-hour customer service window. Messages that initiate a business-initiated
conversation will require a message template.
All conversations are measured in fixed 24-hour sessions.
Each WhatsApp Business account (WABA) will receive 1,000 free conversations per month.

Webhooks
Subscribe to Webhooks to get notifications about messages your business receives
and customer profile updates.
Whenever a trigger event occurs, the WhatsApp Business Platform sees the event and
sends a notification to a Webhook URL you have previously specified. You can get two
types of notifications:
● Received messages: This alert lets you know when you have received a message.
These can also be called "inbound notifications" throughout the documentation.
● Message status and pricing notifications: This alert lets you know when the status of
a message has changed —for example, the message has been read or delivered.
These can also be called "outbound notifications" throughout the documentation.

22.
Webhook SetUp
Setting up any Webhook requires you to:
● Create an endpoint on a secure server that can process HTTPS requests.
● Configure the Webhooks product in your app's App Dashboard.
Your endpoint must be able to process two types of HTTPS requests: Verification
Requests and Event Notifications.
Since both requests use HTTPs, your server must have a valid TLS or SSL certificate
correctly configured and installed. Self-signed certificates are not supported.
If any update sent to your server fails, we will retry immediately, then try a few more
times with decreasing frequency over the next 36 hours. Your server should handle
deduplication in these cases. Unacknowledged responses will be dropped after 36 22
