If you sell to other businesses, the moment a lead turns into a real opportunity matters. Someone has to turn that lead into a contact, an account and a deal, and then keep track of who on the buyer’s side is the decision maker and who is just evaluating. Zoho CRM does that work, and it exposes it through an API, so your website forms, your other business tools or an AI assistant can move leads along and keep the deal team straight without anyone clicking through screens.
What Zoho CRM does
Zoho CRM is the sales and customer relationship management platform from Zoho Corporation, which Zoho describes as AI-powered. Teams use it to manage leads, contacts, accounts, deals, activities and customer engagement across channels. A CRM, short for customer relationship management, is simply the system of record for who your customers are and where each sale stands. Zoho publishes its API descriptions as OpenAPI, a standard machine-readable format, and also offers server-side SDKs, a webhook feature it calls Instant Notifications, and a hosted MCP product for AI assistants.
What you can get done
Opportunity & Pipeline Management
Your pipeline is the list of deals in progress. These calls handle the step where a qualified lead becomes a deal, one at a time or in bulk, and they keep track of which people are attached to each deal.
GET /Leads/{leadId}/__conversion_optionsshows which existing contacts or accounts a lead matches before you convert it.POST /Leads/{leadId}/actions/convertconverts a qualified lead into a contact, account and deal.POST /Leads/actions/mass_convertconverts many leads in one job.GET /Leads/actions/mass_convertchecks whether that bulk job has finished.GET /{module}/{dealId}/Contact_Roleslists the contacts on a deal and the role each one plays.
Customer Data Management
Contact roles are the labels you give people on a deal, such as Decision Maker or Evaluator. Keeping that list tidy keeps reporting honest.
GET /contacts/roleslists the contact roles defined in your CRM.POST /contacts/rolescreates new contact roles, such as Technical Buyer.PUT /contacts/rolesrenames or reorders several roles at once.DELETE /contacts/rolesremoves a batch of roles you no longer use.
Ask for it in plain language
Zoho CRM has 36 phrasing overlays on APIs.io. They map plain questions to the operation that answers them, so an AI assistant knows which call to make. These are the kinds of questions they cover:
- How do I convert a qualified lead into a contact, account and deal?
- Which contacts are involved in a deal and what role does each play?
- How do I find out whether a mass lead conversion finished?
- How do I add a new contact role such as Technical Buyer?
- Can I add several contacts to a deal with their roles in one request?
The Zoho CRM Actions API phrasing overlay is a good place to start.
Getting started
Zoho CRM is a hosted service you call over the web, freemium and self-service; plans are in the pricing section of its APIs.io profile. Start with the Zoho CRM API v8 documentation and the notifications guide, then browse the Actions API, Contacts API and Contact Roles API on APIs.io.
If your team converts leads by hand every week, the convert call is the one to try first.
