Example

// install package with `npm install --save mailslurp-client`
import { MailSlurp } from "mailslurp-client"

// instantiate a client with API KEY
const mailslurp = new MailSlurp({ apiKey: 'your-api-key' })

// create an inbox with a random email address ending in @mailslurp.com
const { emailAddress, id } = await mailslurp.createInbox()
expect(emailAddress).toContain("@mailslurp.com")

// for full control over inbox email addresses use a custom domain
const customInbox = await mailslurp.createInbox("test@mydomain.com")
