Getting Started

Let us start by defining a few WhatsApp jargon like WhatsApp Business App, WhatsApp Business API, WhatsApp API Provider, etc..

WhatsApp Business App: WhatsApp Business is a free download application designed for small business owners. You can create a catalog to showcase products and services and connect easily with your customers with automation, sorting, and instant-messaging tools.


WhatsApp Business API: If the number of chats is getting overwhelming, it is time for a paid service- WhatsApp Business API. WhatsApp Business API will help small and medium-sized businesses communicate with customers around the world so that they can connect with WhatsApp in a simple, secure, and reliable way. To get WhatsApp Business API, you can contact any of the WhatsApp Business API providers like Yellow Messenger. Yellow Messenger is also a WhatsApp partner.


WhatsApp API Provider: To help you achieve your business aims, there are many official WhatsApp business API providers, who will help you out with API as well as the verification process. It takes 3-4 weeks for verification and an active WhatsApp Business API. Yellow Messenger is the official WhatsApp Business API provider as well as WhatsApp partner.


WhatsApp Business API Key:  To establish your business presence on WhatsApp environment, you need an API key. Integration of the WhatsApp API in website or software helps you to get almost unlimited access to customer care or other messaging services.

WhatsApp Business API Profile: The WhatsApp Business profile allows businesses to establish a presence on WhatsApp using WhatsApp Business API. Unlike other messaging apps, the profile will not be searchable in WhatsApp itself so it is up to the business to promote their presence. The WhatsApp Business profile includes a cover photo, description, address, email, website and business hours for your WhatsApp Business account.

 Official WhatsApp business account: These accounts appear with a WhatsApp verified green tick next to their name. A business account on WhatsApp can either be listed as an "Official business account" or a regular "Business account". A business can't request or pay to turn a "Business account" into an "Official business account".

As of now, only certain business accounts are listed as "Official business accounts". Listing a business as an "Official business account" is based on a variety of factors, such as whether the brand is notable or not. There is no official process for this process, but if you want to get it done, you can contact your WhatsApp Partner to help get you started.


Contact Opt-In & Verification: Before you start sending messages on WhatsApp Business API, WhatsApp needs users to give active consent. Enterprise can take user opt-in on their website during account creation for their customers, or paper form, or SMS or on Phone Calls (IVR, etc). Once a customer opts-in, you can import them to a CRM. WhatsApp Business API has a function that allows you to verify that the customer's phone number is a valid WhatsApp account before you send a message. Template Messaging: Sending a message to your WhatsApp contact, requires an approved messaging template. WhatsApp charges per template message, with prices varying depending on the region you send these messages from and to. So what is a WhatsApp template message exactly? Template messages are strings of text, with placeholders, pre-approved by WhatsApp. Pre-approval ensures that sales-related or bulk marketing messages cannot be sent easily after 24 hours. WhatsApp Business API has 15 messages per second template messaging rate limit as an additional safeguard from sending out promotional content, so don’t think for a second that you can get away with sending promotional content on WhatsApp Business.
