Dealing with Chime SDK for creating rooms & attendees

chime-methods.js

/* On the server */
const AWS = require('aws-sdk')
const chime = new AWS.Chime({ region: 'us-east-1' })

// create a room
const meeting = await chime.createMeeting({
  ClientRequestToken: uuid(),
  MediaRegion: 'us-east-1'
}).promise()

// add an attendee to a room
const attendeeResponse = await chime.createAttendee({
  MeetingId: meetingId,
  ExternalUserId: 'some-unique-subject-id' 
}).promise()

// get a room
const room = await chime.getMeeting({
  MeetingId: meetingId
}).promise()

// remove a user from a room
await chime.deleteAttendee({
  MeetingId: meetingId,
  AttendeeId: attendeeId
}).promise()

// close a room
await chime.deleteMeeting({ MeetingId: meetingId })
  .promise()

The Lambda you use for the Chime SDK is likely these IAM permissions.

I recommend avoiding doing chime:*.
