Healthcare APIs - How to Select and Integrate for Medical Solutions

Application Programming Interfaces (APIs) have gained popularity with the rising need to share information across diverse solutions. These small pieces of code that act as an intermediary between different applications have gained prominent status in promoting data access and exchange, execution of business logic, and all manner of transactions.

The Deloitte API Economy report  observes that APIs are becoming a more and more important part of business models. One of the key reasons for this demand include the ability to use APIs to generate revenue from organizational assets.

Healthcare APIs

For the healthcare industry, APIs are finding revolutionary use. This is mainly because healthcare is one of the fastest growing sectors in the world and technology is playing a huge role in this growth. Healthcare APIs allow different healthcare solutions to communicate with each other and exchange data. This is essential in an industry where data is constantly changing and new discoveries are being made. Healthcare APIs are also being used to develop new applications that can help providers improve patient care and create a huge impact.

Benefits of integrating healthcare APIs in medical solutions

The core benefit of healthcare APIs is the facilitation of interoperability. The number of players in this sector is ever growing, with patients using different providers for different needs. This calls for better coordination.  A study by Black Book Research affirms this, indicating that 93% of patients surveyed in the US alone are complaining about poor data exchange. Even worse, two thirds of respondents said they would actually abandon a provider who does not support data exchange. Luckily the medical APIs can easily take off this pain point. Here are the main benefits:

  • Accelerated innovation: Healthcare APIs can accelerate innovation in the healthcare industry by providing a way for developers to easily access data and build new applications.
  • Increased revenue: Healthcare APIs can also help to increase revenue for healthcare companies by making it easier for third-party developers to create new products and services that use data from the company's systems.
  • Improved decision-making: Healthcare APIs make it easier for clinicians to access data and make better decisions about treatment.
  • Cost reduction: Healthcare APIs help to reduce costs by making it easier for organizations to automate tasks and exchange data between systems.

How to select select the right healthcare APIs

There are quite a number of healthcare APIs already in the market, all very good but also serving different needs. So it’s really important that you take time to select the correct one for your project.

Consider these factors:

  • Compatibility: Make sure that the healthcare API you select is compatible with your existing systems and infrastructure. Otherwise, it could lead to integration problems and data inconsistencies.
  • Security: Healthcare APIs need to be highly secure in order to protect sensitive patient data. Make sure that the healthcare API you select includes robust security features such as encryption and authentication, not forgetting compliance with regulations such as HIPAA.
  • Scalability: Ensure that the healthcare API  can scale up or down as needed. This is especially important for organizations that are growing quickly or varying amounts of data to process .
  • Support: Make sure that the healthcare API  you choose comes with adequate support from the vendor. This includes things like online documentation, customer service, and regular updates.
  • Price: Consider your budget when selecting a healthcare API. Make sure that the cost of the API is reasonable and within your budget constraints.

Healthcare API challenges

While healthcare APIs are making a huge difference in helping developers across organizations to create innovative healthcare solutions, they also come with a couple of challenges that you ought to be aware of.

1. Lack of real-time data

This means that developers may not be able to get the latest information on items like drugs, patients, their conditions, and treatments. This can lead to outdated and inaccurate information being used to develop healthcare solutions.

2. Security and privacy concerns

Since healthcare APIs give developers access to sensitive patient data, there is a risk that this data could be leaked or stolen. This could have serious implications for the privacy of patients.

3. Interoperability issues

Different applications may not be able to communicate with each other, making it difficult to exchange data and information. This can make it difficult to develop integrated healthcare solutions.

4. Limited functionality

Some APIs may only provide access to certain parts of a patient’s medical record or only allow for certain types of queries. This can make it difficult to develop comprehensive healthcare solutions.

5. Vendor Lock-in

This occurs when a developer becomes reliant on a specific API provider and finds it difficult to switch to another provider. This can limit or derail a developer’s ability to innovate and create new Healthcare solutions.

Standards for healthcare data sharing

Data sharing is not only sensitive but dynamic. There are different datasets in the healthcare industry, all with different formats and requirements. To make it easier to share this data, there are standards that provide guidelines for both the providers and users of data. There are several standards, but let’s discuss two examples.


FHIR stands for Fast Healthcare Interoperability Resources and was developed by HL7, a health standards developing body. The FHIR standard defines the structure of where data should live and how it should look. It also outlines how different pieces of information should work together. So, if a developer is creating an app that needs patient data from a hospital’s electronic health record (EHR) system, FHIR provides the framework for how to request that data, what format it will be in when you receive it, and how to incorporate it into the app.FHIR is based on RESTful web services—the same kind used by most websites to deliver content. This makes FHIR very flexible and scalable, which is one of the reasons why it’s become so popular.


The United States Core Data for Interoperability ( USCDI) standard is a set of classes and elements for exchanging health information nationwide. It includes classes for patient demographics, medications, allergies and adverse reactions, laboratory test results, smoking status, clinical notes and more.

Popular healthcare APIs

Healthcare APIs can be divided into various categories depending on their main purposes. Here is a look at some of the popular APIs today and what they offer.

1. Human API
