**Description/Error**  
Caused by: com.zoom.v2client.ApiException: {“code”:124,“message”:“Invalid access token.”}  
at com.zoom.v2client.ApiClient.invokeAPI(ApiClient.java:643)  
at com.zoom.v2client.api.MeetingsApi.meetings(MeetingsApi.java:940)

**Which Endpoint/s?**  
[https://api.zoom.us/v2/users/{userId}/meetings](https://api.zoom.us/v2/users/%7BuserId%7D/meetings)

**How To Reproduce (If applicable)**  
Steps to reproduce the behavior:

1. Generate the Java API from the Swagger 2.0 file
2. Call the MeetingsApi.meetings(userId, type, 30, 1) method

**Screenshots (If applicable)**

**Additional context**  
I am using JWT token authentication. Using the same token works fine from the Zoom test site at [https://marketplace.zoom.us/docs/api-reference/testing-zoom-apis](https://marketplace.zoom.us/docs/api-reference/testing-zoom-apis) but fails with the error above when used with the generated API code.

At first I wondered if my account had the correct permissions, but if the call works from the Zoom test site then that shouldn’t be the issue I would think.

Note, this endpoint also works fine with the same JWT token when called using the Unirest Java library.

Why is this error happening?  
Thanks.

Hey @lweber.bt_dev,

We believe this is related to:

> [@Issues with Swagger client generation for Java](https://devforum.zoom.us/t/issues-with-swagger-client-generation-for-java/6105):
>
> I have noticed two problems with the generated Java client code. At the moment, these require manual changes by me in order to use the client API code. The user ‘pmi’ field is typed as a Java Integer in the InlineResponse20033 model class, but the field is required to have 10-digits. This means that any pmi which represents a number greater than 2147483647 (0x7FFFFFFF) will overflow the Java Integer type, and de-serialization (for example, Jackson libraries) will throw an exception. The ac…

In the meantime, while we are working to fix, I would suggest coding the request and JWT Authentication Bearer manually without the generated code.

JIRA: DEVELOPERS-404

Thanks,  
Tommy

Thanks for the reply, Tommy. I must now admit that I just discovered this one was my fault; as long as I set the JWT token then the call itself succeeds.

Hey everyone,

Recently we launched **Zoom Rivet for Node.js**. Zoom Rivet is **Zoom’s Official API Library and API Wrapper**.

We currently support Node.js. Java, Python, GO, C#, and other languages are coming soon or being considered.

[Zoom Rivet](https://developers.zoom.us/docs/rivet/javascript/get-started/) is available on [npm](https://www.npmjs.com/package/@zoom/rivet) and can be used to automatically handle [OAuth](https://developers.zoom.us/docs/rivet/javascript/authorization/) and easily call [Zoom APIs](https://developers.zoom.us/docs/api/) like [Meetings](https://developers.zoom.us/docs/api/meetings/), [Phone](https://developers.zoom.us/docs/api/phone/), [Users](https://developers.zoom.us/docs/api/users/), [Team Chat](https://developers.zoom.us/docs/api/team-chat/), [Chatbot](https://developers.zoom.us/docs/api/chatbot/), [Accounts](https://developers.zoom.us/docs/api/accounts/), [Video SDK](https://developers.zoom.us/docs/api/video-sdk/), and more. It even includes a Webhook server to easily receive Zoom [Webhooks](https://developers.zoom.us/docs/api/webhooks/).

```auto
npm install @zoom/rivet

```

Example that handles OAuth and calls a Meeting API and listens to a webhook event:

```js
import { MeetingsS2SAuthClient } from "@zoom/rivet/meetings";

(async () => {
   const meetingsClient = new MeetingsS2SAuthClient({
      clientId: process.env.CLIENT_ID,
      clientSecret: process.env.CLIENT_SECRET,
      webhooksSecretToken: process.env.WEBHOOKS_SECRET_TOKEN,
      accountId: process.env.ACCOUNT_ID
   });

   // Rivet Events and Endpoints Go Here

   meetingsClient.endpoints.meetings.getMeeting({
      path: { meetingId: "MEETINGID" }
   }).then((response) => {
      console.log(response)
   });

   meetingsClient.webEventConsumer.event("meeting.started", (response) => {
      console.log(response.payload);
   })

   const server = await meetingsClient.start();

   console.log(`Zoom Rivet Events Server running on: ${JSON.stringify(server.address())}`);
})();

```
