To test the function integration

1. Add test data in Zoho CRM according to your workflow rule criteria.
   
2. Check for the data received from Zoho CRM via function, in your application.
   
3. Modify your function code in Zoho CRM, if data is not received or if there is a data mismatch.
   
4. Continue this test until you obtain the required data from Zoho CRM to your Application.
   

Important Notes

• You can associate up to 6 (1 Instant Action and 5 Time-Based Actions) Functions per workflow rule.
  
• You can execute only 5000 lines (Statements) in a single function call.
  
• You can transfer data for a maximum of 10 CRM fields from Zoho CRM to third-party applications using function.
  
• If you use function to update any CRM field, then after saving the record the updated field value will appear in the record detail page without having to reload the page.
  For example, if a function is configured to update lead rating value via the Data Enrichment tool, then after saving a record the field will be updated automatically. It will be highlighted for easy identification. (Note that, the popup will be displayed only once). 
  
  
• You can retrieve data from other Apps to Zoho CRM using function.
  
• You must update the API ticket regularly according to limits in third-party applications.
  
• You will not receive any email notification, if the function integration stopped functioning due to any issue in a third-party API.
  
• If there is any failure while connecting to Zoho Creator service, function will send the second notification after 15 min. Thereafter, the system will not send any notifications for that particular workflow trigger. Errors returned from Zoho Creator are shown under Reason for Failures section.
  
• If you exceed the maximum count per day, the system will not send remaining function notifications to third-party applications and will notify the failure to Administrator.
  
• Zoho CRM will send the data in following standard format for Date and Date Time fields to third-party applications:
  • Date: yyyy-MM-dd
    
  • Date Time: yyyy-MM-dd hh:mm
    
• Limits for Functions:
  • Min calls per day - 20,000 + 500 calls per user license for the org.
    Max calls per day - 100,000 whichever is lower.
    For example, if you have 55 users in your organization, you will have a maximum of (55 x 500 + 20,000) = 47500 calls per day.
  • Integration Tasks - 25000 Zoho API calls/day using deluge.
    
  • Get Data & Post Data - 25000 calls/day (totally) 
    
  • Send Email - 1000 emails/day
