REST/Web API Template (MS Word) + Tutorial

Need to write API documentation but don’t know where to start? We hear you. We’ve been there. That’s why we created this easy-to-use template to get you started and put a framework in place for your API reference documents. It also includes a 16-page tutorial that explains what you need to include in your API documents, with example of how to describe your endpoints, parameters, and other settings.

This template isn’t for expert or senior tech writers. Rather, it’s for junior tech writers, developers, or anyone else who’s been asked to document an API and needs some help to get started. The price is pretty reasonable when you think how long it would take to come up to speed and create your own writing guidelines. That’s it. Here’s what’s inside.

  • Use this 28-page MS Word template to document your REST/Web APIs. This template pack includes detailed examples, guidelines, and screenshots.
  • You also get a 16 page How to Write API Document tutorial that explains how to write each section in your API reference documentation. It includes helpful explanatory text that walks you through the process of documenting each section in the API, including the parameters, endpoints, requests, responses, and endpoints.

You can change everything in the document – text, images, and tables. There are no special plug-ins, macros, or installation files.

Why Write API Reference Documentation?

If your company develops APIs, then you can use this MS Word template to write reference documentation for each API available with the product. The API documentation describes the common components used by each of the APIs for iOS, Android, and other platforms. Use the API reference documentation to explain the data structures available through the APIs.

This will increase the usage and popularity of your APIs and encourage developers, testers, and integrators to use your API products.


This is the cover page – you can remove the image if you want to – with the document conventions and legal text.


Each section includes explanatory text, tables to present the information, and sample default values to put things in context.


The document is designed to be read. We use lots of white space and tables to make it easy to scan the text and find what you’re after.
