Use when a lead is qualified and ready to enter the sales pipeline. Convert a qualified Zoho CRM lead into a Contact + Account + Deal — the key sales qualification step
zoho_create_account
Account_Name is required. Industry should match Zoho industry picklist values. Once created, contacts and deals can be linked to this account. Create a new account (company/organization) in Zoho CRM with name, industry, phone, and website
zoho_create_contact
Last_Name is required. Account_Name links the contact to a company account. Use for adding qualified individuals — not raw leads (use zoho_create_lead for unqualified prospects). Create a new contact in Zoho CRM with name, email, phone, and linked account for customer management
zoho_create_lead

Get records related to a parent record in Zoho CRM — e.g., contacts of an account, deals of a contact, notes of a lead

zoho_search_leads
Returns lead name, email, company, lead source (Web/Advertisement/Referral), lead status (Not Contacted/Contacted/Junk), and owner. Leads are the top-of-funnel — unqualified prospects.
