What is a difference between meeting key and meetingId?

[mococo]

I'm using Webex XML API, but I want to migrate this API to rest API. I noticed something after read through the rest api documents. they are using meetingId to get a meeting data instead of meeting key and session key. What is a difference between them? and how to get a meetingId through the rest api?

Meeting Key in the XML API is usually the Meeting Number in the REST API (not to be confused with meetingId in the REST API, which is different).

If you have the meeting Key/number, then you can use that in the https://developer.webex.com/docs/api/v1/meetings/list-meetings API (you may also need to add the from and to date fields if the meeting is older than a few days or in the future). The response from this API should include the meetingId then. You use this throughout the Meetings REST APIs then, for most endpoints.
