API Limits

The Zoho CRM Platform API is available in all editions of Zoho CRM. To use the API, you'll require the Authentication Token from your CRM account. Please make sure that you have the permission to access the API service. If you do not have permission, please contact your CRM administrator.

Zoho CRM Platform Edition	API Requests - Upper Limit
Free Edition	1000 requests/day/organization
Standard Edition	Min - 2000 requests/day/organization Max - 5000 requests/day/organization or 250 requests /user license whichever is lower
Professional Edition	Min - 3000 requests/day/organization Max - 10000 requests/day/organization or 250 requests /user license whichever is lower
Enterprise Edition	Min - 4000 requests/day/organization Max - 25000 requests/day/organization or 500 requests /user license whichever is lower

The PST Time zone will be considered.
We notify CRM administrators (Users with "Administrator" profile) if your organization exceeds the API limit. We also provide API Statistics for better assessment of your integration requirements.
To optimize your API usage, get maximum 200 records with each request and insert, update or delete maximum 100 records with each request.
Example: If you have purchased 10 user licenses, you are allowed 2500 requests per day. Using each of those 2500 requests, you can update maximum 100 records. That would be 2500 x 100 i.e. 250,000 records can be updated/inserted/deleted per day.
In case, your application requires more than the upper limit, your additional API requests will not be processed. To avoid data transfer issues, please assess your API requirements well in advance.

You can view the total limit for API calls and the current day's API usage in Zoho CRM.

In Zoho CRM, click Setup > DeveloperSpace > CRMAPI.
In the CRM API page, the UsageInformation section lists the per day usage and total limit for the API calls.
