API Limits

Zoho Writer APIs enforce a threshold limit, the number of calls allowed within a minute, an hour, or a day, to ensure fair usage and system stability. If a threshold limit is hit, a cooling period applies, which is the wait time before you can make further calls to that API.

The tables below list the applicable limits and cooling periods for each API.
