Getting Started with WhatsApp Cloud API
Introduction
Welcome to the WhatsApp API from Meta.
Individual developers and existing Business Service Providers (BSPs) can now send and receive messages via the WhatsApp API using a cloud-hosted version of the WhatsApp Business API. Compared to the previous solutions, the cloud-based WhatsApp API is simpler to use and is a more cost-effective way for businesses to use WhatsApp. Please keep in mind the following configurations:
| Name | Description |
|---|---|
| Version | Latest Graph API version. For example: v13.0 |
| User-Access-Token | Your user access token after signing up at developers.facebook.com. |
| WABA-ID | Your WhatsApp Business Account (WABA) ID. |
| Phone-Number-ID | ID for the phone number connected to the WhatsApp Business API. You can get this with a Get Phone Number ID request. |
| Business-ID | Your Business' ID. Once you have your Phone-Number-ID, make a Get Business Profile request to get your Business' ID. |
| Recipient-Phone-Number | Phone number that you want to send a WhatsApp message to. |
| Media-ID | ID for the media to send a media message or media template message to your customers. |
| Media-URL | URL for the media to download media content. |
