Updated 19 December 2023 |

As competition in the eCommerce market grows more intense, so does demand for extra software functionality. With enhanced features, business owners can have greater sales and thus a better place on the market.

It means that eCommerce software vendors - multichannel, shipping management systems, marketing automation tools, and so on - work very hard to improve their software. The best way to catch up in this competition is likely through an integration between eCommerce software and platforms such as Shopify. It facilitates working with Shopify customer data and other such information.

The compatibility with various platforms means that the software providers can get all the data they need to provide a basic function. In addition, it's a means to add more customers and increase their satisfaction.

In this article we are going to look at why accessing eCommerce platforms 'customer data is so important for software providers. Moreover, we will teach you to make Shopify customer API integration.

Why do eCommerce Software Need to Work with e-stores’ Customer Data?

You'll know how to integrate with Shopify and work with Shopify customer data, but before that, you need to understand why your eCommerce software needs to access and work with e-store customer data.

The data relating to customers is stored in clients’ e-shops built on eCommerce platforms like Shopify, Magento, BigCommerce, etc. The eCommerce software needs such data for several cases.

For example, shipping management systems need data related to customers, including customer name, address, email, phone number, etc., to create shipping labels.

Similarly, marketing automation systems need such data so they can send automated emails to online store customers.The access to customer data allows marketing software to notify e-store clients about discounts, new products, offers, and order status changes.

However, in order for these eCommerce software to pull customer data from shopping platforms such as Shopify, they must develop an integration between their systems and the Shopify customer API. Without such integration, software vendors will not be able to access customer data from e-shops and propose their solutions to e-merchants.

The integration helps connect the software to the shopping platforms where the e-retailers have their stores. This enables seamless data transfer from eCommerce platforms to the software. So, being integrated with shopping platforms, software solutions can directly access, edit, modify and delete customer data from them.

Development of the Integration with Shopify

In order for software vendors to develop an integration between their software and Shopify, you need to connect your software to the Shopify API.

The Shopify API is an intermediary tool between the software and the shopping platform. It allows getting access to data from Shopify-based customer online stores. The API enables the direct transfer of data between connected systems.

Shopify API accepts both data formats - JSON and XML. Also, it works with such types of HTTP requests as GET, POST, PUT, and DELETE. Shopify API supports methods like Category, Customer, Order, Product, etc. So, the software vendors can easily retrieve all the data they want. For Shopify customer data, the vendors need to work with Shopify customer API.

Shopify Customer resource stores data related to the e-shops’ customers. It includes the info on customer contact numbers, email addresses, names, and everything related to their order history. It also contains information about whether or not the customer has agreed to receive automated emails from the shopping platform. The Shopify customer API also stores a customer’s account status.

Usage of Shopify API allows you to add, delete, modify customer details along with getting a list of all the customers from the e-stores.

All you need is to connect your software with Shopify API. After that, its customer resource will let you retrieve all the Shopify customer data. Such integration can be done in-house or with the help of third-party services.

While in-house integration development is expensive, time-consuming, and resource-consuming, third-party integration development is a profitable deal.
