# Introduction to MeasureOne Quickstart

Welcome to the **MeasureOne Quickstart Guide**! This resource is your gateway to integrating seamlessly with MeasureOne's APIs. Whether you're looking to build a native integration or prefer a hybrid approach, this guide is crafted to provide you with a solid starting point.

Through this guide, you'll learn how to:

- Generate and securely store your API keys.
- Set up a development environment tailored to MeasureOne.
- Run a functional application to interact with MeasureOne's services.


By the end of this Quickstart, you'll have a working application capable of:

- Establishing a secure connection with MeasureOne's API.
- Handling data requests and processing responses.
- Implementing real-time functionality, like webhooks, for event-driven workflows.


Let's get started on building a seamless MeasureOne integration that powers your application with efficiency and reliability!

## **1. Setting Up the Environment**

MeasureOne supports two environments for your integration needs:

| Environment | Description |
|  --- | --- |
| **Staging** | Ideal for testing and development |
| **Production** | For live, customer-facing applications. |


Each environment operates on a distinct infrastructure and requires unique access credentials. For this exercise, we'll be using the **Sandbox** environment, which is part of the Staging setup.

## **2. Accessing Your Credentials**

To integrate with MeasureOne, you'll need a `client_id` and `secret` for each environment. You can retrieve these credentials by logging into the [Staging Dashboard](https://dashboard-stg.measureone.com/home/developers/api-keys).

| Key | Description |
|  --- | --- |
| **client_id** | Private identifier for your team |
| **secret** | Private key, one for each of the three environments |


MeasureOne requires authentication for all API requests using access tokens. If an `access token` is missing from your request, an authentication error will be returned.

- Sign up or log in to [MeasureOne's Stage Dashboard](https://dashboard-stg.measureone.com/home/developers/api-keys) to get your API credentials
- Once you have `client_id` and `secret` you need to generate `access token` by calling this [API](/api/openapi_3.2/openapi/api-keys-and-access/paths/~1v3~1auth~1generate_access_token/post).
