# List Opportunities

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

Retrieve a paginated list of opportunities.

Supports:

* Pagination (`page_size`, `page`)
* Date filtering (`updated_after`, `updated_before`)
* Phase entry/exit date filtering (`entered_phase_id`+`entered_after`/`entered_before`, `exited_phase_id`+`exited_after`/`exited_before`)
* Sorting (`order_by`, default: desc)
* Field search (`title`, `address`, `primaryName`, `primaryPhone`, `primaryEmail`)
* Full text search (`q`)

**Note:** The `/requests` path is an alias for `/opportunities` and will continue to work until users are individually notified and migrated.

**Note:** If an opportunity 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.

**Note:** `entered_phase_id`/`exited_phase_id` identify a phase *template* (shared across all deals on a workflow), not a specific phase instance. Use the `phaseTemplateId` from a `GET /opportunities/{opportunity_id}` response or the `GET /workflows` response to find the id for a given phase (e.g. "Closed - Won"). When either filter is used, each row also includes a compact `phaseTimeline` (`phaseTemplateId`, `startedAt`, `completedAt`); use `GET /opportunities/{opportunity_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` (OpportunitiesGetParametersUpdatedAfter, optional) — Filter items updated after this timestamp (ISO 8601). Also matches records whose custom property values changed within the window.

- `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_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
