# Initialising a process flow & sending data via the Patchworks API

## Introduction

This section walks through the steps required to pass data from your own system into a Patchworks process flow, via the Patchworks API.

## Assumptions

To complete these steps it's assumed that you have:

* [Registered for a Patchworks account](https://doc.wearepatchworks.com/product-documentation/registration/registering-for-a-patchworks-account) and have a username and password to access your Patchworks dashboard
* [Built at least one process flow](https://doc.wearepatchworks.com/product-documentation/process-flows/building-process-flows) that you want to update via the Patchworks API

## What you need to do

The required steps are detailed in the following stages:
