Weโll be using the RestSharp library, a simple REST and HTTP API Client for .NET, to interact with the Whapi.Cloud API.
The first step is to register on the Whapi.Cloud website and create an account. It's free and doesn't require you to enter a credit card.
After registration you will immediately have access to a test channel with a small limitation. Wait for it to start (it usually takes about a minute). You will need to connect your phone for Whatsapp automation. It is from the connected phone that messages will be sent.
Open your WhatsApp mobile app, navigate to Settings -> Linked devices -> Link a device -> Scan QR code
Our service enables you to interact with the API without the need for an uninterrupted phone connection. Operate WhatsApp on up to four paired devices and one mobile device concurrently.
Now save the generated API-Key token on channel page:

We offer a convenient service for testing requests and using ready-made code fragments in any programming language. You will only need to transfer the saved API-token and fill in the required parameters:
