Navdeep Singh : Securing The Supply Chain - Best Practices For API-Driven B2B Integrations

Supply chains today depend more than ever on fast, reliable communication between systems. Whether it's sending a purchase order, confirming an invoice, or tracking a shipment, the way companies exchange this information is advancing. More businesses are now turning to APIs, Application Programming Interfaces, to handle these digital conversations.

Unlike older systems that move data in batches or require strict file formats, APIs let businesses connect in real time. They allow two systems to talk to each other directly, pulling or sending information as needed. But with this increased openness comes a new challenge: how to keep these digital doors secure.

As someone who works closely with enterprise integration and supply chain systems, he has learned that security can’t be treated as a checklist item at the end of a project. It needs to be part of the process from day one. APIs make it easier for businesses to stay connected, but only if they’re designed and managed with care.

What’s Different About APIs?

Older technologies like EDI have been a staple in supply chain operations for years. They’re dependable but rigid. APIs, on the other hand, offer more flexibility. They allow companies to plug into cloud-based platforms like SAP Ariba, Coupa, or Oracle and exchange data with suppliers or partners in near real time.

But while APIs help simplify integration, they also introduce new risks. Unlike older, closed systems, APIs are often exposed to the internet. That means the information being shared for orders, pricing, customer data can be vulnerable if the right security measures aren’t in place.

Practical Ways to Secure API Integrations:

Here are some of the most important steps any business can take when using APIs to support supply chain processes:

1. Control Who Gets Access

Not everyone needs access to everything. Use systems that can issue secure tokens and control which users or systems can interact with each part of the API. This helps make sure that only authorized connections are allowed.

2. Protect the Data While It’s Moving

Use encryption, especially when information is being sent across public networks. This protects sensitive data like prices, tax IDs, or customer records, even if someone tries to intercept it.

3. Monitor the System

Set up systems that can watch how your APIs are being used. This helps catch unusual behavior quickly, like repeated failed login attempts or traffic from an unexpected source. Keeping good logs also helps during audits or if anything goes wrong.

4. Don’t Accept Just Any Data

APIs should be careful about what kind of data they accept. If your system expects a purchase order with certain fields, it should reject anything that doesn’t meet that format. This helps prevent accidental errors and protects against attempts to misuse the system.

5. Plan for Growth and Change

APIs, like any software, will need updates over time. Make sure your systems are set up to handle different versions and give partners enough time to adjust when changes are made.

Make Security a Team Effort:

In most of the successful integration projects led by Navdeep, the key factor has been technology and teamwork. When IT, security, procurement, and supplier teams work together from the beginning, it’s easier to design an integration that works well and stays secure.

Suppliers, too, need clear documentation and testing opportunities so they know what’s expected. Open conversations with external partners reduce the chances of confusion and help solve problems faster.

Follow the Rules That Matter:

It’s also important to remember that different industries and regions have different data rules. In Europe, for example, businesses must follow GDPR when dealing with personal data. Healthcare and financial sectors have their own requirements too.

Companies need to make sure their API setups respect these rules, especially if they’re moving customer data, financial details, or anything subject to regulation. That means being thoughtful about what data is collected, how long it’s stored, and who has access to it.

Also, companies should check in on their suppliers and vendors. If someone else is connecting to your system, their weaknesses can become your problem. It’s a good idea to review their security posture regularly.

Final Thoughts:

APIs have become the preferred option for connecting systems in modern supply chains. They’re quicker and more flexible than traditional setups, but they also require more attention when it comes to security.

Putting the right controls in place doesn’t need to be complicated. It’s about starting early, thinking practically, and making sure the right people are part of the conversation. Security isn’t a one-time task, it’s an ongoing part of managing a connected business.

The more businesses treat APIs like essential infrastructure, and not just code, the better prepared they’ll be to handle the growing demands of today’s supply chains.
