> I would like to know if there is any limit on subscribing to events for multiple customers. i.e. since we are taking the client-credential token specific to a marketplace app, and using this token while calling the event\_subscription APIs, so wondering if there is any limit here.  
> Consider, there are 1000 customers accounts to which I would want to subscribe to meeting events using this event\_subscription API, so hope it would allow me to execute these many.

@ucczoomaruba the rate limit is the same regardless of whether you want to do this for multiple different accounts because it’s your credentials that were used to create the token and make request at the app level. There may be response headers for this endpoint where you can see your specific rate limit. Additionally, your admin portal dashboard on Zoom Marketplace should also indicate your rate limit and usage. See [this thread](https://devforum.zoom.us/t/zoom-phone-api-doesnt-return-x-rate-limit-remaining-in-headers/99819/8) for more info.
