## Update `client.opportunity.update(stringid, OpportunityUpdateParamsbody, RequestOptionsoptions?): OpportunityUpdateResponse` **post** `/v1/opportunities/{id}` Updates an existing opportunity by ID. Only included fields and relationships are modified. The `$opportunityStatus` field is read-only and cannot be updated. The `$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. **[Required scope](/using-the-api/scopes/):** `opportunities:update` **[Rate limit category](/using-the-api/rate-limits/):** Write ### Parameters - `id: string` Unique identifier of the opportunity to update. - `body: OpportunityUpdateParams` - `fields?: Record` Field values to update — only provided fields are modified; omitted fields are left unchanged.
