**Hi All!**

Is there a API Limitation when Authenticating ZOOM using OAuth Flow ?  
Our Application use Zoom API. There for Authentication we are using OAuth2.0.  
While Doing the Authentication we have noticed an Issue.

**Issue is**  
When we trying to Authenticate Zoom Multiple Times in **Production Environment** we are getting an 400 BadReq Error from the Zoom API.  
This happen at the stage we are passing the Init **CODE** and trying to get Token.  
Then again after some time passed (like 30min+) then Authentication going to work again without an Issue.

Here what i mean ` Authenticate Zoom Multiple Times` is something like this,

### Production Environment

```auto
Step-01: Authenticate Zoom ( This working 200 status with Token )
Step-02: Disconnect the Prv Authenticated Zoom.
Step-03: Again Authenticate Zoom ( This return 400 Status )
Step-04: Again Authenticate Zoom ( This return 400 Status )
.
.
( some time passed 30min + )
Step-n: Authenticate Zoom ( This working 200 status with Token )

```

**This Only Happen in Production Environment Only**

When we trying to Authenticate Zoom In **Development Environment** multiple times, It going to work without any issue, Always return 200 response with token.

### Development Environment

```auto
Step-01: Authenticate Zoom ( This working 200 status with Token )
Step-02: Disconnect the Prv Authenticated Zoom.
Step-03: Again Authenticate Zoom ( Working 200 status with Token )
Step-02: Disconnect the Prv Authenticated Zoom.
Step-04: Again Authenticate Zoom ( Working 200 status with Token )
.
.
Step-n: Authenticate Zoom ( Working 200 status with Token )

```

## NOTE

Here for Production and Development both Envs we are using the same Zoom OAuth Application.

## I want to know is there Production Related API Limitation in ZOOM when getting Tokens or doing Authentications ??

( I didn’t able to find some documentation base on this )
