What is an e-commerce API?
API is an acronym for application programming interface.
Simply put, APIs help different software “talk” to each other. In more technical terms, API is a set of definitions and protocols that enable data transmission between software programs.
In the same vein, e-commerce APIs help applications inside and outside of an e-commerce platform communicate with one another. They’re particularly important in a headless commerce architecture as they connect the front- and back-ends of an e-commerce site.
Types of APIs
Broadly speaking, APIs can be divided into three types: public, partner and private. This section elaborates on each of them.
1. Public APIs
Also known as open APIs, public APIs are available for use by any developer outside of an organization.
Some public APIs are free to use, whereas others require a subscription fee. Fees are usually charged on a pay-as-you-go basis, with the amount calculated based on the number of calls made to the API.
2. Partner APIs
Partner APIs are offered only to a company’s partners. They are typically used by strategic business partners or authorized clients for data sharing.
For example, Shopline’s enterprise clients can use the e-commerce platform’s API to connect to SleekFlow, an omnichannel messaging platform. This would allow users to automate the sending of messages to customers based on pre-set triggers, such as order confirmation, delivery status updates, etc.
3. Private APIs
Private APIs are also known as internal APIs. Typically, private APIs are developed by companies to establish connections between different systems or products of theirs.
An example of private APIs at work is the integration of QuickBooks’s accounting software with its inventory management software. The private APIs are used only within the company to achieve a specific goal, and aren’t available for outside developers.
Role of APIs in modern enterprises
A tech-enabled e-commerce company has many software programs in place. At the heart of this ecosystem are APIs which connect different systems, enabling them to communicate with one another, hence exposing usable data to users.
Against this backdrop, MuleSoft, an API platform owned by Salesforce, advocates an API-led approach to connectivity within modern enterprises. Under this methodology, APIs are grouped into three categories and have different roles:
1. System APIs
The core function of system APIs is unlocking data from your company’s systems of record.
To illustrate this, customer relationship management (CRM) and enterprise resource planning (ERP) systems often have proprietary and complex interfaces. By building system APIs to connect with these software and extracting data from them, users can easily access and use data from these databases without learning to navigate the underlying systems.
2. Process APIs
Process APIs are used to integrate different systems in an IT ecosystem. An example is the process of e-commerce order fulfillment.
When fulfilling a customer order, various domains of your company’s IT ecosystem need to be engaged, such as the inventory and order management systems. The process API would interact with the systems APIs of different databases (i.e. inventory and order), combining data from these sources to enable the order fulfillment process.
3. Experience APIs
Experience APIs help deliver specific user experiences. More specifically, APIs of this type reconfigure data and present them in a format that is most easily consumed by the intended audience.
For example, the orders API (which is a process API) has exposed data of customer orders in JSON format. However, the marketing team of your company wants to feed this data into an application software that only accepts data in XML or CSV format. In this scenario, an experience API will transform and present the data in the desired form.
Benefits of APIs for e-commerce
“Why should I use APIs for my e-commerce business?” Some people may ask.
In short, having APIs in your tech stack is helpful for integrating your platform with solutions that are imnsely beneficial to business growth and success. Here are four benefits of APIs for e-commerce explained:
E-commerce businesses need to stay agile to succeed in a highly dynamic environment, and APIs are key to organizational agility.
For example, numerous new methods of payment emerge as the payments landscape evolves. In Southeast Asia alone, more than 150 digital wallet licenses have been issued to date. Instead of developing dedicated gateways for each payment option, a payment API would empower digital merchants to process online payments at their stores easily and seamlessly.
In this day and age, there’s no shortage of data available to businesses. The difficulty, however, lies in access and exchange of data across different software applications, and APIs can help you overcome this challenge.
Whether it’s the sharing of data between the order and inventory management software, or the construction of a holistic view of your customers, APIs can bridge the gap between systems and offer instant connectivity, opening up new possibilities for how data can be used.
Designed with a service-oriented approach, the same API can be used across different systems and applications. This means you can always leverage prebuilt APIs instead of spending time to build new ones.
In this respect, the benefits of APIs come in the form of cost and time savings, as you don’t have to hire developers to design self-contained or proprietary solutions, the process of which is often expensive and time-consuming.
APIs add extra functionality to your e-commerce ecosystem without changing your existing software, systems or programs. Streamlining workflow and scaling your e-commerce business therefore become faster and easier.
e-Commerce API examples
From order management to payment and marketing, there are many aspects in which APIs can be applied in an online shop. Below are 9 examples of APIs for e-commerce:
1. Authentication API
Sometimes known as login API, an authentication API verifies the identity of a user attempting to sign in at your e-commerce site. For instance, customers need to enter a one-time password (OTP) sent to their registered email address or phone number in order to login to their accounts.
This type of APIs provides an additional layer of security beyond usernames and passwords, protecting customers from password attacks and enhancing security at your online store.
2. Catalog API
Using a catalog API, you can easily create, edit or remove product items in your catalog. Some catalog APIs can also be integrated with other systems in your business, such as inventory management, order fulfillment and reporting tools.
3. Inventory API
An inventory API can be used to retrieve inventory data from a given database. With this API, you can sort or filter inventory data by different parameters, such as SKU, stock level and storage location. You can also perform batch updates of inventory quantities for your online shop.
4. Marketing API
Marketing APIs are useful to optimize the marketing performance of a business.
For example, Facebook’s Conversions API connects your marketing data to Facebook’s system. This would help Facebook’s algorithms measure the results of advertising, improve ad targeting, reduce cost per action and increase your return on ad spend.
5. Orders API
As its name indicates, an orders API exposes details about orders created on an e-commerce site, such as order dates, order items, order values, etc. Developers can then build web or mobile applications, using order information to track sales performance or customer behavior.
6. Payment API
A payment API enables you to accept payments at your online store.
Stripe’s Payment Methods API is an example of payment API. Once the API is activated, customers will be able to pay for an online order with a variety of methods, including credit cards, ACH debit transfers, Google Pay and many others.
7. Product information API
Product information APIs help you extract product information like product description, price, product ID, specifications and images from a given product page or a database.
This type of API is commonly used by developers seeking to develop applications to be integrated into e-commerce platforms. Currently, many product information APIs are available for scraping data from online marketplaces and e-tailers like Lazada, eBay, Walmart, ASOS and Forever 21.
8. Shipping API
Shipping APIs integrate the functionality of third-party carriers to an e-commerce site. They allow users to create shipping orders, print shipping labels and track shipments easily, hence automating the e-commerce order fulfillment process.
An example of shipping API in action can be seen from Shopline, an Asia-based e-commerce platform, which allows merchants to create a waybill with SF Express in one click:
9. Validation API
This type of API verifies details entered by customers on your e-commerce website.
A case in point to illustrate this is typos in email addresses. Due to the proximity of the characters “m” and “n” on the keyboard, many customers would type “gnail.com” or “gmail.con” instead of the correct domain name, “gmail.com”.
Validation APIs would verify customers’ input and identify possible errors, eliminating the hassle of verifying customer information and minimizing deliverability issues.
