APIs are crucial for various businesses across industries, as they change how you can operate in the market. This article will provide a comprehensive API access definition and describe the types available, how to use an API, and how they benefit your business. BMA recognizes this and continues to make API’s seamless to our clients.

What Is API Access?

API stands for Application Programming Interface. It’s a program that allows systems to interact with each other and defines when and how this can happen. When the systems interact, they can share data, functionalities, services, and other features that benefit both systems.

Why Is API Access Important?

Why do we need an API? Having API access is crucial for systems, applications, and services to communicate with each other. API access control allows for smooth operation and automation between platforms, which helps streamline processes, improve productivity, and improve the user experience. Within the BMA platform we continually offer API access for vendors that our clients want or are familiar with using.

How Does API Access Work?

API access provides specified endpoints that determine which functionalities are available for internal or external use. Users or partnered systems can send requests through the access point, and the API processes the information to complete the requested action, delivering it on the initial request.

Types of APIs

Several API access options can be used, including composite, open, partner, and private. Here’s a breakdown of each API option.

Composite APIs

A composite API combines multiple APIs or services into a single interface to simplify access and enhance functionality. Composite APIs can be made up of open, partner, or private APIs.

Open APIs

An open or public API is publicly available for external use and allows third-party developers to access specific processes or information. Some open APIs are freely accessible, while others are subscription-based, depending on usage.

Partner APIs

This is an external API that is only shared with trusted partners that do business with the API company. A partner API is typically used when a company wants to limit who can access their data and how they use it.

Private APIs

A private API, also known as an internal API, is only used within a specific company to facilitate communication between internal systems and applications. Any third-party entities cannot access this type of API.

Benefits of Adopting API Access

When you adopt API access for your business, there are several benefits you can enjoy.

Scalability and Flexibility

With API access, you can quickly scale your services and applications as needed. This gives you the flexibility to adapt to changing requirements or add new features, helping you stay competitive in the market.

Increased Productivity

API access management allows you to automate various processes. This automation reduces the manual intervention required of your team, helping them save time, minimize errors, and boost their overall productivity.

Increased Revenue

With data access API, you can create new partnerships, collaborations, and third-party integrations. These connections allow you to monetize your API access through licensing, subscriptions, or usage-based models, which can generate additional revenue for your business.

Further Innovation

API access is an excellent way to promote innovation, experimentation, rapid prototyping, and ecosystem development. This system encourages developers to build upon existing services and create new applications, offerings, and solutions to improve customer experiences and increase market competitiveness.

Seamless Integrations

One of the best benefits of API access is its seamless integration with other application programming interfaces and software systems. These integrations allow data to move smoothly between applications, boosting functionality and creating a unified user experience.

Data Monetization

Since data can move easily between application programming interfaces, selected functionalities and datasets can be shared with external parties. This exchange of information allows businesses to monetize data assets and share them responsibly.

Enhanced Collaboration

API access allows developers, partners, and stakeholders to work together to create better solutions, enhanced offers, and further market differentiation.

Extended Functionality

API access management gives your developers additional access to services and functionalities offered by your API partners. This means your developers can grow the software you have based on others’ successes instead of creating something from scratch. Extended functionality allows you to better meet your users’ diverse needs and preferences.

Securing API Access

While data is shared between multiple API access points, it’s still essential to protect client information and sensitive data. Here are the ways you can secure your API access points.

Authentication and Authorization

When you implement authentication and authorization as part of your API access management, you can determine who is accessing the platform and how much information they can see. Some of these security mechanisms include basic, API key, and JWT-based authentication, and OAuth 2.0 or OIDC.


You can encrypt your data as it moves between platforms by using Transport Layer Security or Secure Sockets Layer encryption programs. These protocols ensure data stays confidential and can’t be accessed or intercepted by unauthorized users.

How Is API Access Secured?

In addition to the options mentioned above, API access can also be secured through other means, including:

  • Role-based access controls (RBAC): These controls allow access based on roles and provide audit logs to monitor and manage API usage.
  • Data validation: Validate inputs and outputs using validation techniques to guard against data breaches.
  • Rate limiting: To help prevent system misuse, set rate limits for how often and for how long APIs can be accessed.
  • API gateways: Gateways have built-in security features like traffic monitoring, firewalls, and threat detection to prevent unwanted system abuse.
  • Regular audits: With regular security audits and vulnerability assessments, you can identify and address potential weaknesses in the system.
