# Generate PDF invoices from JSON rows

**Use case:** 

Builds a PDF invoice from the sample row, with two line items, 8.25% tax and the shared seller details and terms, and returns a download link for the file. Line totals, tax and balance due are computed for you. Pick a receipt, quote, packing slip or your own HTML template, and swap in your own rows.

## About this Actor

This example demonstrates how to use [Document Generator: invoices, receipts and quotes to PDF](https://apify.com/examsens.ai/document-generator.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/examsens.ai/document-generator.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/examsens.ai/document-generator.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
