Zoom Phone Rate limits don't seem to match with the documentation

API and Webhooks
1

Hi Guys,

I’m trying to do multiple calls to Zoom Phone API and I’m getting an error of Rate limit (specifically this one: {"code":429,"message":"Sorry, the maximum number of api requests is already reached. Please try later."} even though I’m nowhere near the number specified in the documentation.

This is exactly what’s happening in my code:

  • I get a new access token with the refresh token flow.
  • I enumerate all the users from zoom.
  • I call /phone/users/{userId}/voice_mails & /phone/users/{userId}/recordings for each user.

In this flow, for my case I end up making 13 API calls. These calls take time to resolve (between ~200 & 900ms), let’s take the “worst” case for our scenario, all calls take 200ms, in that case I’m doing ~5 API calls per second which is way below the rate limit specified in the documentation (160 Request/Second).

If I put a pause of 1 second between each call I don’t receive this error ever, I tried running my code multiple times and couldn’t see this error under this conditions.

With a pause of 500ms between each call the error happens in the forth run or something around that.

Any help is much appreciated.

Thanks!

Hey @jarrieta,

I was able to reproduce this and will investigate why this is happening and will get back to you.

Thanks,

Hey @jarrieta,

The Zoom Phone engineering team said that the rate limiting for the Zoom Phone API is 1 request per second.

I will update our rate limit documentation to include this.

Thanks,
Tommy

Hey @tommy

Quick question, is this something that will be improved in the future?

Hey @jarrieta,

I’d assume so, but let me confirm.

In a future release the rate limit will be increased. I don’t have a specific timeframe/date though.

Hey @jarrieta,

We updated our docs with the Zoom Phone API rate limits.

11

This rate limit common apis 10 request/per second Is for perticular user-Level or account-level ?

Hey @dbbendale, thanks for reaching out.

The rate limits are for both Account and User Level app types.

Thanks,
Tommy
