Convert HTML to PDF with Nutrient Document Web Services API on Zapier

What is Zapier?

Zapier(opens in a new tab) is an automation platform that connects your favorite apps and services with no code required. You can build “Zaps” to automate repetitive tasks by setting up triggers and actions between apps like Google Drive, Slack, Gmail, and more.

In this tutorial, you’ll learn how to use Zapier to automatically convert HTML files into PDF documents using the Nutrient API.

What is the Nutrient API?

Nutrient Document Web Services API is a powerful platform for document automation. With your free account(opens in a new tab), you get 100 credits, which you can use to perform various document operations. Each tool (e.g. conversion, signing, flattening) consumes a different amount of credits depending on complexity.

Nutrient offers more than 30 tools with the ability to:

Convert images and documents to PDF
Merge, split, or reorder pages
Add digital signatures, watermarks, or annotations
Run OCR, redact, flatten, and more

All you need is an API key from a free account to get started(opens in a new tab). You can chain these tools together in Zapier to build powerful, automated PDF workflows.

What you’ll need

A Zapier(opens in a new tab) account (a pro plan is necessary for multi-step Zaps)
