Webhook is a feature that allows you to receive a callback from our server when a message is incoming to your device. You can use this feature for made a dinamic chatbot or whatever you want.
We will send a POST request to your webhook url with a JSON body. Here is an example of the JSON body we will send:
{
"device" : "your sender/device"
"message" : "message",
"from" : "the number of the whatsapp sender",
"name" : "the name of the sender",
"participant" : "sender number if group"
"bufferImage" : "base64 image, null if message not contain image",
}
