I am using the Zoho CRM API in a VB.NET program and have been successfully inserting records into modules, using the duplicate check feature such that records are either inserted or updated as appropriate.  The records to be inserted/updated are in the form of a daily csv file  - some new records, some existing records, but none of them have Zoho IDs.

The challenge I now have is with custom modules – I understand that duplicate checking is not available in custom modules.  So my plan is this:

·         Search for record already existing in Zoho

·         If it does, update it

·         If it doesn’t, insert it

Alternatively I could delete all records in the custom module, then re-insert all the records from the csv file.

The problem I have is, as I understand it, I need the unique ID of a record to update or delete it, yet I can find no way to obtain the record ID as part of the search response.  Also, there appears to be limitations on how frequently and how many times per day searchRecords can be called.

Any help you can give on the above scenario would be greatly appreciated.

Regards,

Andy
