## Create

`client.opportunity.create(OpportunityCreateParamsbody, RequestOptionsoptions?): OpportunityCreateResponse`

**post** `/v1/opportunities`

Creates a new opportunity record. The `$name` and `$stage` fields and the `$account` relationship are required.

After creation, Lightfield automatically generates an opportunity summary in the background. The `$opportunityStatus` field is read-only and cannot be set via the API. The `$task` and `$note` relationships are also read-only — manage them via the `$opportunity` relationship on the task, or the `$account`/`$opportunity` note relationships instead.

Supports idempotency via the `Idempotency-Key` header.

To avoid duplicates, we recommend a find-or-create pattern — use <u>[list filtering](/using-the-api/list-endpoints/#filtering)</u> to check if a record exists before creating.

### Parameters

- `body: OpportunityCreateParams`

  - `fields: Record<string, string | number | boolean | 3 more | null>`

    Field values for the new opportunity. System fields use a `$` prefix (e.g. `$name`, `$stage`); custom attributes use their bare slug. Required: `$name` (string) and `$stage` (option ID or label). Fields of type `SINGLE_SELECT` or `MULTI_SELECT` accept either an option ID or label from the field's `typeConfiguration.options` — call the <u>[definitions endpoint](/api/resources/opportunity/methods/definitions)</u> to discover available fields and options. See <u>[Fields and relationships](/using-the-api/fields-and-relationships/)</u> for value type details.
