Developing a Zoom API Client Library for Golang

Repost from my tech blog
https://www.melvinvivas.com/zoom-api-golang-library/

I thought of developing a Zoom API Golang Client Library for my personal use. There is no official Zoom API client library for Go/Golang so I thought it would be interesting to develop one.

Why Zoom?

• Zoom is very popular during this crisis and most businesses and schools are using it. Zoom is also used by families and friends to get in touch during this trying times. This popularity will also give rise to the need to integrate with Zoom.

• There is no official Zoom API client library for Go/Golang.

• I wanted an interesting project to practice my Golang skills and at the same time be able to create something useful for fellow Gophers.

• It would be interesting to know how Go developers will integrate Zoom into their applications.

Here is the github project if you would like to take a peek. I'd really appreciate it if you can give it a star if you liked it or find it useful. Stars will really give me motivation to spend more time on it and implement more functionality. :)

Zoom (Zoom.us) API Golang client library

Zoom(zoom.us) API Golang Client Library

This is an unofficial Go client library for the Zoom API. I've just started and implemented the ff:

• List Meetings
• Create Meetings
• Delete Meeting
• Get Meeting by Id
• Get Meeting Invitation
• Add Meeting Registrant
• List Meeting Registrants
• Update Meeting Status/End Meeting

This library is in its infancy and has not been tested yet for production use.

Zoom API version supported

• Version: 2.0.0
• Host: api.zoom.us/v2

Usage

Set Environment Variables

    export ZOOM_API_URL="https://api.zoom.us/v2"
    export ZOOM_AUTH_TOKEN="<your jwt token>"
    export ZOOM_USER_ID="<your email or username>" 

How to get your Zoom JWT token

You will need a paid account to access Zoom's REST API. You need to create a JWT App in the App Marketplace Then, get a JWT token from the App Credentials of the app you just created. Check the instructions here https://marketplace.zoom.us/docs/guides/build/jwt-app

Download the library to your project

go get

View on GitHub

I am very busy with my daytime job so I only work on the library during late nights and weekends. So far, I have implemented the ff. functionality.

• List Meetings
• Create Meeting
• Delete Meeting
• Get Meeting by Id
• Get Meeting Invitation

This library is in its infancy and has not been tested for production use.

To use the library, you will need a paid account to access Zoom's REST API. Unfortunately, free or basic accounts do not have access to the APIs. You need to create a JWT App in the Zoom App Marketplace and get a JWT token from App Credentials. Here are the instructions I followed to get me started.

The zoom-go library uses environment variables to configure the API client. Here are the required environment variables.

    export ZOOM_API_URL="https://api.zoom.us/v2"
    export ZOOM_AUTH_TOKEN="<your jwt token>" 
    export ZOOM_USER_ID="<your email or username>" 

Download the library to your project

go get "github.com/donvito/zoom-go/zoomAPI"

List Meeting example

func listMeetingExample() {

    //Create a new Zoom API client
        apiClient := zoomAPI.NewClient(os.Getenv("ZOOM_API_URL"), os.Getenv("ZOOM_AUTH_TOKEN"))

        //Retrieve the userId from the env variable
        userId := os.Getenv("ZOOM_USER_ID")

        //Use the client to list meetings
        var resp zoomAPI.ListMeetingsAPIResponse
        var err error

        resp, err = apiClient.ListMeetings(userId)
        if err != nil {
            log.Fatal(err)
        }

        for _, meeting := range resp.Meetings {
            fmt.Printf("id = %d, topic = %s, join url = %s, start time = %s\n", meeting.Id, meeting.Topic, meeting.JoinUrl, meeting.StartTime)
        }

}

Create Meeting example

func createMeetingExample() {
    //Create a new Zoom API client
        apiClient := zoomAPI.NewClient(os.Getenv("ZOOM_API_URL"),
            os.Getenv("ZOOM_AUTH_TOKEN"))

        //Retrieve the userId from the env variable
        userId := os.Getenv("ZOOM_USER_ID")

        //Use the API client to create a meeting
        var resp zoomAPI.CreateMeetingResponse
        var err error

        resp, err = apiClient.CreateMeeting(userId,
            "Contributors Meeting for Project",
            meeting.MeetingTypeScheduled,
            "2020-05-24T22:00:00Z",
            30,
            "",
            "Asia/Singapore",
            "pass8888", //set this with your desired password for better security, max 8 chars
            "Discuss next steps and ways to contribute for this project.",
            nil,
            nil)
        if err != nil {
            log.Fatal(err)
        }

        fmt.Printf("Created meeting : id = %d, topic = %s, join url = %s, start time = %s\n", resp.Id, 
                resp.Topic, resp.JoinUrl, resp.StartTime)

}
