How to initialize an object#

Store your authorization data separate from the code. The library allows you to create a file with an arbitrary name and location in the following format:

API_TOKEN_INSTANCE = "MY_API_TOKEN_INSTANCE"
ID_INSTANCE = "MY_ID_INSTANCE"

You can pass the keys using the below example:

const restAPI = whatsAppClient.restAPI(({
    credentialsPath: "examples\\credentials"
}))
