Frequently Asked Questions (FAQ)

What is API development?

API development is the process of building diverse software components that allow applications to integrate with each other, share data and increase connectivity across your organization.

Many applications have their own APIs, but these aren't always enough to create the integrations you want, scale effectively, or give you the data flexibility you need. Custom API solutions give you flexibility, simplifies IT systems design, and enables innovation when designing or managing tools and products.

Custom API development requires careful planning, which can be broken down into stages. Each stage represents a collection of actions and outputs:

project plan
  • Document opportunities
  • Articulate business outcomes
  • Validate API data sources and functionality
  • Create API Project Brief
  • Collect data source samples
Align organization
  • Review API Product Brief across organization
  • Establish security and privacy requirements
  • Approved API Project Brief functional and non-functional requirements
API design
  • Assemble API design team (incl. senior developers)
  • Create API specification
  • API data access diagrams
  • API specification with sample API responses
API development
  • Assemble API implementation team
  • Build custom APIs with experienced API developers
  • Well-structured API code
  • Automated API testing
API Integration
  • Verify API integration solutions
  • Production deployment

Do you have experience developing APIs for LLMs?

Yes, our team at SoftKraft has experience developing APIs for large language models (LLMs). APIs play a crucial role in AI software development by providing a means to interact with large language models (LLMs). For instance, a company may develop an AI model to perform image recognition. Through an API, other software applications can send images to this model and receive identified objects back from the model.

APIs can also be used to integrate AI services provided by third-party vendors. For example, many cloud providers offer AI and machine learning services that can be accessed and used via APIs. This means companies can leverage sophisticated AI capabilities without the need to develop these complex systems from scratch. One LLM that has been getting a lot of news coverage is OpenAI GPT3, which can be leveraged via API.

Whether you’re looking for broader AI development services or looking to develop an API to leverage LLMs, our team can help.

What is your API development process?

Our development team follows a structured approach when developing APIst to ensure they are flexible, extensible, and meet the needs of your business:

  1. Develop API strategy to deliver business value: Our team initiates every API project by aligning it with your key business objectives. We work with you to identify the core benefits you are seeking from the API, such as revenue growth, enhanced customer value, operational efficiency improvements, or the creation of new premium services.
  2. Define data sources: At this stage we work with you to identify your data sources and understand their structure. We use this information to determine how the new API will interact with these data sources, and what the API's functions will be.
  3. Evaluate existing tech stack: After reviewing the data sources, we look at the broader tech stack that this new API will live within. We clearly identify the role the API will play in this ecosystem.
  4. Define API requirements: At this stage, we have all of the information we need to define a robust set of API requirements - both functional (what the API does) and non-functional (how the API should behave, performance, security, etc.). We work with your team to ensure these requirements meet your expectations before we proceed with any custom API development work.
  5. Choose API data architecture: With the requirements defined, our technical team will choose the most appropriate technology for creating your API, such as REST APIs, Google APIs, GraphQL, or gRPC, based on your specific needs.
  6. Choose API authentication: Our team will review the sensitivity of the data being exchanged and the parties involved in the exchange of data to decide on the most secure and appropriate authentication method.
  7. Create API specification: We use tools like Swagger or RAML to create and maintain your API specifications. These tools help us build easily maintainable APIs by generating up-to-date API documentation as your API evolves.
  8. Develop and deploy API: We implement best practices for API development and use tools like CI/CD for efficient deployment of the custom software.

We believe in working closely with our clients at every step, keeping them fully informed and involved throughout the API development process.

What to look for when hiring an API development company?

The stakes are high when you’re investing significant capital, resources, and time into hiring an offshore software development team to handle your API integration project. You want to choose the right vendor, but with over 23,000 companies offering software outsourcing services on Clutch.co alone, the sheer number of options can be overwhelming.

To help narrow down the options, we recommend that you hire a dedicated development team that has a few core characteristics:

  • Focus on your success: The API development team should be clearly focused on your business needs, requirements, and long-term goals. With this focus, the API development team will be able to purposefully guide you through the entire software development process end-to-end.
  • Experienced engineering leader: Look for a team of API developers with a comprehensive portfolio that displays their proficiency and experience in providing API development and integration services across a wide range of projects.
  • Process excellence: Choose a partner that has a clear software development team structure and that has an agile software development process, based on adaptive planning, early delivery, and project updates. This will ensure you are up to date with what's happening at any stage of project development.
  • Effective communication skills: Strong communication abilities are essential to ensure seamless collaboration and successful project execution. The software development company’s in-house project manager should be prepared to provide the level of communication you desire. When in doubt, ask detailed questions about the level, type, and frequency of communication that they can provide.

By considering these factors, you'll be better equipped to hire a dedicated team of API developers that can not only meet your needs but also contribute to the overall success of your business.
