Build a flow with Zoho Projects Provider API documentation

Data types

Validation status

Implemented · fixture tested.

Implementation is checked against provider-shaped fixtures for every action, authentication failures, rate limits, pagination and duplicate safety. Provider sandbox and authorised account validation are recorded separately when credential-backed runs are completed.

Authentication

Plans and access

All Zoho Projects plans; time logs, phases budgets and custom fields depend on the edition. Calls act as the user who authorised the OAuth client and follow that user's portal profile and project roles.

Test environment

Use a Zoho Projects trial or free portal for testing.

Rate limits

200 calls per 2-minute window per API endpoint; exceeding it blocks that endpoint for 10 minutes (Retry-After is sent).

Provider events

Zoho Projects webhooks configured per portal for task, project and phase events. Nexra event triggers are not yet available; flows run on demand or on a schedule.

Before you build a flow

Uses the V3 API (/api/v3 and /api/v3.1 for phases); the legacy /restapi endpoints are not used.
Milestones are called phases in V3; Nexra uses the V3.1 phase endpoints.
The incremental task filter uses last_updated_time greater_than with a date (day precision), as documented.
Time log lists require a date range of up to 6 months and a module type (task, issue or general).
Custom fields are read and written by API name (cf_...); fetch definitions with List custom fields.
Task updates add owners with the documented owners add form; removing owners is not automated, and this nested form could not be verified against a live portal.
Zoho has no idempotency key; uncertain creates are not repeated automatically.
