# List Projects

GET https://api.coperniq.io/v1/projects

Retrieve a paginated list of projects.

Supports:

* Pagination (`page_size`, `page`)
* Date filtering (`updated_after`, `updated_before`, optionally widened to project-level line item edits via `include_line_item_updates`)
* Phase entry/exit date filtering (`entered_phase_id`+`entered_after`/`entered_before`, `exited_phase_id`+`exited_after`/`exited_before`)
* Sorting (`order_by`)
* Field search (`title`, `address`, `primaryName`, `primaryPhone`, `primaryEmail`)
* Full text search (`q`)

**Note:** `updated_after`/`updated_before` also match projects whose custom property values changed within the window.

**Note:** If a project has no `title` (empty or whitespace-only), the response returns the parent account's `title` instead. The stored value is not modified — this is a read-time fallback only. Title-based search (`title` query param, full-text `q`, or the `/projects/search` endpoint with `prop=title&op=contains`) also matches projects whose own title is null/empty when the parent account's title matches the search term.

**Note:** `entered_phase_id`/`exited_phase_id` identify a phase *template* (shared across all projects on a workflow), not a specific phase instance. Use the `phaseTemplateId` from a `GET /projects/{project_id}` response to find the id for a given phase. When either filter is used, each row also includes a compact `phaseTimeline` (`phaseTemplateId`, `startedAt`, `completedAt`); use `GET /projects/{project_id}` for the full `phaseInstances` with names/positions/SLA.

## Authentication

- `x-api-key` header (required) — API Key authentication via header

## Request

### Query parameters

- `page_size` (integer, optional, default: 20) — Number of items per page (max 100)
- `page` (integer, optional, default: 1) — Page number (1-based)
- `updated_after` (ProjectsGetParametersUpdatedAfter, optional) — Filter items updated after this timestamp (ISO 8601). Also matches records whose custom property values changed within the window.
- `updated_before` (ProjectsGetParametersUpdatedBefore, optional) — Filter items updated before this timestamp (ISO 8601). Also matches records whose custom property values changed within the window.
- `include_line_item_updates` (boolean, optional, default: false) — Requires `updated_after` and/or `updated_before` to also be passed — has no effect on its own. When true, widens that window to also match projects whose project-level line items (estimate/scope items) were added or edited in the window, and adds a `lineItemsUpdatedAt` field to each returned project (the most recent `updatedAt` among its own scope line items, `null` if none). Line items on quotes/invoices are excluded. Deletions and reorders are not detected. Ordering remains on the project's own updatedAt, so this flag is not a replacement for a full change-feed. Default: false. Only applies to project list/search endpoints.
- `entered_phase_id` (integer, optional) — Phase template ID to filter by phase-entry date. Required when `entered_after` or `entered_before` is provided. Given alone (no date bounds), matches records that ever entered this phase.
- `entered_after` (string, optional) — Only include records that entered the phase given by `entered_phase_id` on or after this date/timestamp. Accepts a date (`2026-07-01`) or a full ISO 8601 timestamp (`2026-07-01T00:00:00Z`). Requires `entered_phase_id`.
- `entered_before` (string, optional) — Only include records that entered the phase given by `entered_phase_id` before this date/timestamp (exclusive). Accepts a date (`2026-08-01`) or a full ISO 8601 timestamp (`2026-08-01T00:00:00Z`). Requires `entered_phase_id`.
- `exited_phase_id` (integer, optional) — Phase template ID to filter by phase-exit date. Required when `exited_after` or `exited_before` is provided. Given alone (no date bounds), matches records that have exited this phase at any point.
- `exited_after` (string, optional) — Only include records that exited the phase given by `exited_phase_id` on or after this date/timestamp. Accepts a date (`2026-07-01`) or a full ISO 8601 timestamp (`2026-07-01T00:00:00Z`). Requires `exited_phase_id`.
- `exited_before` (string, optional) — Only include records that exited the phase given by `exited_phase_id` before this date/timestamp (exclusive). Accepts a date (`2026-08-01`) or a full ISO 8601 timestamp (`2026-08-01T00:00:00Z`). Requires `exited_phase_id`. On opportunities, combine with `exited_phase_id` set to a "Closed - Won"-style phase template to find deals that closed within a date range.
- `order_by` (enum, optional, default: asc) — Sort order for results
  - Allowed values: `asc`, `desc`
- `include_virtual_properties` (boolean, optional, default: false) — Whether to include virtual properties in the response. Defaults to false unless explicitly set to true.
- `include_archived` (boolean, optional, default: false) — Whether to include archived (inactive) records in the response. By default only active records are returned.
- `include_contacts` (boolean, optional, default: false) — Whether to include associated contacts in the response. Defaults to false unless explicitly set to true.
- `q` (string, optional) — Full text search query
- `title` (string, optional) — Title search query
- `address` (string, optional) — Address search query
- `primaryName` (string, optional) — Contact name search query
- `primaryPhone` (string, optional) — Contact phone search query
- `primaryEmail` (string, optional) — Contact email search query
