# Add rows

`POST /sheets/{sheetId}/rows`

Inserts one or more rows into the sheet specified in the URL. If you want to insert the rows in any position but the default, use [location-specifier attributes](/api/smartsheet/openapi/rows) (that is, toTop, toBottom, parentId, siblingId, above, indent, outdent). See language tabs for variations in syntax.

Note: This operation does not add rows with cells that have images. However, you can upload an image to a cell *after* the cell exists in a sheet. To do so, call the operation described in the [Add Image to Cell](/api/smartsheet/openapi/cellimages/addimagetocell) page.

This operation supports both single-object and bulk semantics. For more information, see [Optional Bulk Operations](/api/smartsheet/guides/advanced-topics/scalability-options#bulk-operations).

## Other responses

- `default` — When **allowPartialSuccess=false** (or not specified): If an error occurs, the [Error object](/api/smartsheet/openapi/schemas/error) returned contains a **detail** attribute set to an object with the following attribute: * **index**: the array index of the row that caused the error (0 if a single Row was passed in) If any error occurs, the entire request fails (no rows are added), and the error response returned describes the first problem that was encountered. For example: ``` { "errorCode": 1042, "message": "The cell value in column 5504245941200772 did not conform to the strict requirements for type CHECKBOX." "detail": { "index": 4 } } ``` When **allowPartialSuccess=true**: When partial success is enabled, and one or more of the objects in the request fail to be added/updated/deleted, a standard [Result object](/api/smartsheet/openapi/schemas/result) is returned, but with a **message** of **'PARTIAL_SUCCESS'** (instead of **'SUCCESS'**), and a **resultCode** of **3**. Additionally, the object contains a **failedItems** attribute -- an array of [BulkItemFailure objects](/api/smartsheet/openapi/schemas/bulkitemfailure) that contains an item for each object in the request that failed to be added/updated/deleted.
