--- title: Zoho CRM API Integration on Truto slug: zohocrm category: CRM canonical: "https://truto.one/integrations/detail/zohocrm/" --- # Zoho CRM API Integration on Truto **Category:** CRM **Status:** Generally available ## Unified APIs ### Unified CRM API - **Accounts** — The accounts represent a company in a CRM. - **Contacts** — The contacts represent an existing point of contact at a company in a CRM. - **Engagement Types** — The engagement types represent an interaction activity in a CRM. - **Engagements** — The engagements represent an interaction noted in a CRM. - **Fields** — The fields of entities in a CRM. - **Leads** — The leads represent a potential customer in a CRM. - **Notes** — The notes represent a note on another object in a CRM. - **Opportunities** — The opportunities represent an opportunity in a CRM. - **Tasks** — The tasks represent a task in a CRM. - **Users** — The users represent a user in a CRM. ### Unified User Directory API - **Me** — - **Roles** — The Role object represents a role of a User. - **Users** — The User object represents a User. ### Unified Search API - **Search** — Search endpoint for all the apps. ## How it works 1. **Link your customer's Zoho CRM account.** Use Truto's frontend SDK; we handle every OAuth and API key flow so you don't need to create the OAuth app. 2. **Authentication is automatic.** Truto refreshes tokens, stores credentials securely, and injects them into every API request. 3. **Call Truto's API to reach Zoho CRM.** The Proxy API is a 1-to-1 mapping of the Zoho CRM API. 4. **Get a unified response format.** Every response uses a single shape, with cursor-based pagination and data in the `result` field. ## Use cases - **Sync leads and contacts bi-directionally with Zoho CRM** — SaaS companies offering lead generation, marketing automation, or data enrichment tools need to keep their product's contact database in lockstep with their customers' Zoho CRM. Truto's Unified CRM API handles the sync for Leads, Contacts, and Accounts without building against Zoho's API directly. - **Log external engagement data into Zoho CRM automatically** — Sales dialers, email outreach platforms, and messaging tools need to push call logs, email opens, and meeting notes back into Zoho so reps have full context without switching apps. The Engagements and Notes resources in Truto's Unified CRM API make this straightforward. - **Automate deal stage progression from external triggers** — Proposal tools, billing platforms, and contract management SaaS products need to move Zoho Deals forward — for example, updating an Opportunity to 'Closed Won' when a contract is signed — so the sales pipeline stays accurate without manual intervention. - **Enrich and score CRM records with product or third-party data** — PLG and customer success platforms pull Contacts and Leads from Zoho, compute health scores or PQL scores, and write those values back into custom fields. This gives sales teams actionable signals inside the CRM they already use. - **Route and assign tasks to the right Zoho CRM user** — Workflow automation and customer success tools need to create follow-up Tasks in Zoho assigned to the correct owner based on territory, role, or round-robin logic. Truto's Users and Roles resources enable accurate ownership resolution before task creation. ## What you can build - **Real-time caller ID with CRM context** — Use the Unified Search API to look up an incoming phone number or email, instantly surface the matching Contact or Lead record, and display deal history and notes to agents before they pick up. - **One-click proposal generation from CRM data** — Pull Account details, Opportunity line items, and deal amounts from Zoho CRM via the Unified CRM API to auto-populate proposals and contracts inside your product. - **Custom field mapping UI for end users** — Fetch available Fields from Zoho CRM dynamically so your customers can map your product's data model to their heavily customized Zoho modules — no hardcoding required. - **Automated churn-risk task creation** — When your product detects a churn signal, resolve the Account Owner via the Users resource and create a check-in Task in Zoho CRM assigned to that rep automatically. - **Bi-directional lead sync with source tracking** — Upsert Leads captured in your product into Zoho CRM with Lead Source tags, and pull updates back so both systems stay in sync without duplicate records. - **Engagement timeline embedded in your product** — Read Engagements, Notes, and Tasks associated with a Contact or Opportunity from Zoho CRM and render a unified activity timeline inside your own UI. ## FAQs ### What authentication method does Zoho CRM use, and does Truto handle it? Zoho CRM uses OAuth 2.0 with short-lived access tokens and refresh tokens. Truto manages the full OAuth flow — including token refresh and multi-datacenter support (zoho.com, zoho.eu, zoho.in, etc.) — so your team never deals with auth plumbing. ### Can I read and write custom fields in Zoho CRM through Truto? Yes. The Unified CRM API exposes a Fields resource that lets you dynamically discover all standard and custom fields on modules like Leads, Contacts, and Opportunities. You can then read and write those fields when creating or updating records. ### How does Truto handle Zoho CRM's API rate limits? Zoho CRM enforces per-minute and daily API call limits that vary by plan. Truto manages pagination, request batching, and retry logic with appropriate backoff so your integration stays within limits without manual throttling on your side. ### Which Zoho CRM objects are available through Truto's Unified CRM API? The Unified CRM API covers Accounts, Contacts, Leads, Opportunities (Deals), Engagements, Engagement Types, Notes, Tasks, Users, and Fields. A Unified User Directory API (Me, Roles, Users) and Unified Search API are also available. ### What if I need a Zoho CRM endpoint that isn't covered by the Unified API? Truto builds additional tools and proxy endpoints on request. If you need access to a Zoho CRM capability not yet covered — such as Blueprints, custom modules, or specific automation triggers — the Truto team can scope and deliver it. ### Does Truto support Zoho CRM's multi-datacenter architecture? Yes. Zoho CRM hosts data across multiple regional datacenters (US, EU, IN, AU, JP, etc.). Truto detects and routes API calls to the correct datacenter for each connected account, so your integration works globally without extra configuration.
