# Introduction to Procurement API guide
Welcome to the Procurement (consumers) application. The application provides an intuitive web interface for ordering products from a variety of suppliers, but we also offer these features as an API, allowing your customer to interact with Procurement from inside your software.
Please note, this guide is only applicable for the V2 API (schema).
After following this guide, your software will be able to help your customers:
- Find and connect with suppliers on the Procurement platform
- Browse available products
- Express their requirements and convert them into orders
- Track the status of orders and their related invoices
We have built a small demo application showing each of these features, with some examples of how to present the data to the user:
# Zaikio app setup
Before we start writing any code, we will however need to first get permission to manage customer information in Procurement, and for that we'll need to register a Zaikio application and then install the app as an organization.
Once your application is created, you will need to ask users for permission to access Procurement on their behalf. Procurement offers the following OAuth scopes, which should be configured in your app on the Hub and in your OAuth configuration:
| ||Search for products|
| ||View or request connections with suppliers|
| ||Create and view material requirements|
| ||Create and view orders and invoices|
Once you've completed these steps and have authorised an organization, let's continue this guide by looking at finding & connecting suppliers.
