# Bulk post rows in batches of 3

**Use case:** 

Packs several rows into each request for APIs that accept an array of records, wrapped in the field name the API expects. Cuts the cost of a large sync, because you are charged per request rather than per row. This example really sends to a public test endpoint so you can see the responses.

## Input

```json
{
  "data": [
    {
      "sku": "A-1",

## About this Actor

This example demonstrates how to use [Dataset to REST API (Sync Rows to Any API)](https://apify.com/nerolabs/dataset-to-rest-api.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/nerolabs/dataset-to-rest-api.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
