API Integration Tips
The success of your API integration hinges on several crucial factors. Let's explore what you need to consider before getting started.
Make Sure Everyone Speaks the Same Language
The first thing to consider when connecting your systems is compatibility. Think of it like getting a group of friends from different countries to chat – they need a common language to understand each other.
In this case, the language is how your systems format data, follow protocols, and use standards. Make sure everything lines up to avoid any hiccups in communication.
Keep Up with the Latest
APIs are living documents, constantly evolving with updates and changes. Staying on top of these is important, like checking a user manual for your new gadget.
Understanding the API's "endpoints" (think of them as doorways) helps you manipulate data and keeps everything running smoothly.
Building for the Future
As your business grows, so will your needs. Think of choosing an API like picking a car – you need a reliable one to handle the journey. Ensure the APIs you choose can scale up with you and handle increasing demands.
Also, consider how fast the API responds – nobody likes waiting for a slow system.
Security First, Always
Just like locking your doors at night, security is crucial for APIs. Data breaches can be a nightmare, so make sure the API has strong security measures in place, like authentication (checking IDs) and encryption (scrambling data).
Verifying these measures is vital to keeping your information safe and complying with privacy laws.
Successful Examples
Numerous industries have successfully embraced API integration to streamline their operations. For instance, Salesforce, a renowned SaaS platform specializing in customer relationship management, effectively utilizes its API to enable data sharing and synchronization between its platform and other business tools and applications.
Reshma Khilnani, Co-founder and CEO of Medplum, a provider of open source healthcare technology, has firsthand experience with API Integration:
“As technology makes inroads into more traditional industries like healthcare, financial services, government, and real estate, understanding and complying with the associated regulations is quickly becoming a requirement for many technical leaders. Developing software, particularly API integrations for regulated industries, can be daunting, and engineers often think of regulatory burdens as ‘someone else’s' problem. However, I believe you can create a lot of value by learning some basic techniques for building API integrations in a regulated space.
Reshma shares two specific examples where API integrations in healthcare could come in handy:
- Integrating two health record systems: synchronizing patient identifiers and demographics using an industry-standard FHIR (g)(10) interface.
- Running an automated OFAC check before creating a bank account for a business, to ensure the business has not been sanctioned.
Following is a brief playbook highlighting common “regulated industry integration plays” that span multiple industries.
| What you’ll see | What to do | Examples |
| Integrations in the regulated space often have common compliance requirements. Common technical building blocks: e.g. audit logging, authentication, role-based access control | Build common compliance building blocks into your integration in a reusable way to support multiple compliance frameworks with ease. The systems you are integrating with will have these baked in as well. | Use of an enterprise identity provider like Azure SSO or Okta checks many compliance boxes |
| Change management requirements | Build change management requirements into your source control, issue tracking, and CI/CD. | Access driven code approvals, use of ticket tracking systems and release automation. Mapping ISO 9001 to Agile |
| Regulated systems have “a test” that you need to pass | Understand the test well from a technical perspective and build test cases (in code or configs) that act as an audit of your system | Inferno is a test harness for health APIs. Tools like Vanta and SecureFrame act like “test prep” for audits. |
| Software supply chain or “bill of materials” | Have review processes related to what packages are brought into your applications. Have a sensible philosophy on the cadence of upgrade. | Github has a SBOM export feature |
| Confusion from engineering workforce when working in a regulated environment | Many of the things that support regulations also align with useful skills for senior or principal engineers (e.g. writing maintainable code, cross-functional impact, uptime, stability, and security) Add principles like code review, test-driven development, build automation, and code scanning to the rubric for engineers | Mark Cuban has some choice quotes on the topic. |
Reshma continues, “Ultimately, it’s my belief that a technical leader can advance their organization by learning to build integrations effectively for the regulated industry. If you need convincing that this is the case, note that the biggest tech companies—Microsoft, Amazon, Oracle, Salesforce, Google, and others—are investing heavily in compliance for their infrastructure, supporting the regulated applications they need. By incorporating tools to integrate with regulated systems into your software development lifecycle, you can ship much faster and overall be more effective.”
Solutions to Common Challenges
While API integration offers a path to software nirvana, there can be a few bumps in the road. Here are some common challenges you might encounter, along with tips to overcome them:
- Data Disagreements: Imagine two friends trying to have a conversation, but one uses meters, and the other uses feet. Similar issues can arise with data formats.
Solution: Standardize data formats across all systems before integration. Tools like data mapping can help translate between incompatible formats.
- Parsing Puzzles: Sometimes, interpreting data from another system can be like solving a cryptic puzzle. Inconsistent parsing (how data is read) can lead to unexpected results.
Solution: Implement robust error handling mechanisms to catch parsing errors and prevent incorrect data from causing problems. Thorough testing is also key.
- Security Shenanigans: Security breaches are a constant threat. Unsecured API connections can be like leaving your doors wide open, inviting unauthorized access to sensitive data.
