# 🤝 3. Hello System

**DCKAP Integrator makes systems talk to each other.** So far, we have experimented with tools inside the workflow. Now it is time to connect to real systems and see data flow in action.

In this chapter, we shall experiment with:

* Shopify — a popular e-commerce platform
* SFTP — a secure file transfer protocol for reading and writing files

Let’s set up the systems and collect the credentials first.

## How to Create a Trial Shopify Store?

####  What You'll Need Before You Start

 ✅ A valid email address

Note: Based on your use case, add scopes. For our tutorial experiments, we are going to use products API. When working out the exercise, if the use case needs accessing other data, scope needs to be modified here.&#x20;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.dckapintegrator.com/tutorials/workflow-builder-tutorial/3.-hello-system.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
