API SDK

The API SDK JavaScript package provides a list of functions to make it easier to work with the Bandada API.

Example of project using the API SDK library: bandada-api-sdk-demo.

Install library​

npm install @bandada/api-sdk

Create a new instance​

# new ApiSdk(url: SupportedUrl | string, config?: object): ApiSdk

Creates a new instance of ApiSdk using the API URL and the config.

  • Create a new instance using the Bandada API URL and the default config.

This is what you need if you are using the production Bandada API.

import { ApiSdk } from "@bandada/api-sdk"

const apiSdk = new ApiSdk()

This is useful when working with the development environment.

import { ApiSdk, SupportedUrl } from "@bandada/api-sdk"

const apiSdk = new ApiSdk(SupportedUrl.DEV)
  • Create a new instance using a custom API URL.
import { ApiSdk } from "@bandada/api-sdk"

const apiSdk = new ApiSdk("https://example.com/api")
  • Create a new instance using a custom API URL and config.
import { ApiSdk } from "@bandada/api-sdk"

const url = "https://example.com/api"
const config = {
    headers: {
        "Content-Type": "text/html"
    }
}
const apiSdk = new ApiSdk(url, config)
