Celigo API Builder: The first step in full-lifecycle API management

APIs are the backbone of modern business operations, enabling seamless communication between systems, customers, and partners. Whether sharing real-time inventory updates with suppliers or providing sales and support teams with a complete customer 360 view, APIs make connecting and integrating critical business systems easy.
Full-lifecycle API management goes beyond just setting up endpoints; it encompasses four key phases to ensure security, scalability, and performance.
Full-lifecycle API management phases
- Build – Design and configure APIs to fit your business needs.
- Secure – Control access, manage traffic, and maintain compliance.
- Socialize – Share APIs with internal teams and external consumers, complete with documentation.
- Monitor – Track performance, analyze usage, and optimize efficiency.
Effective API management ensures that APIs are secure, discoverable, and optimized for performance. And while every phase is important, it all starts with building APIs tailored to your business and integration needs.
That’s where Celigo’s API Builder comes in.
Build an API in under 3 minutes
API Builder: The easiest way to build APIs
Celigo API Builder simplifies API development with a low-code, visual interface, allowing users to create and manage APIs without complex scripting. Built to be as intuitive as Flow Builder, API Builder enables users to define requests, process responses, and reuse existing integrations—making API creation faster and more accessible.
With 600+ prebuilt connectors, API Builder integrates seamlessly with Celigo’s mapping, transformations, lookups, and branching rules. Since it’s fully embedded within the Celigo platform, existing connections and flow steps can be reused in any API, reducing duplication and development time.
To further simplify API development, Celigo introduces two dedicated API step types:
- API request node – The entry point for defining HTTP methods, setting URIs and parameters, and structuring request schemas.
- API response node – Configures response handling, status codes, headers, and error management.
With these two steps, if you can build a flow, you can build an API—using the same intuitive tools you already know.
Optimized for performance
Speed is critical for APIs, especially in real-time workflows and high-volume data exchanges. API Builder is powered by Celigo’s API Engine, a high-performance runtime designed for near-instantaneous response times.
- Low-latency execution ensures APIs respond quickly, even under heavy traffic.
- Scalability allows for efficient load management, preventing performance bottlenecks.
- Optimized architecture guarantees smooth API operations, minimizing downtime and delays.
With API Builder, your APIs are not only easy to build but also built to perform.
Seamless API management
Once an API is built, Celigo API Management provides advanced security, governance, and analytics to take it to the next level.
- Secure APIs with authentication, rate limiting, and traffic control policies.
- Optimize performance with caching, traffic shaping, and automated OpenAPI spec generation.
- Monitor API usage with built-in dashboards, ensuring peak performance and seamless collaboration.
With Celigo’s unified platform, you can build, secure, socialize, and monitor APIs—all in one place. Instead of juggling multiple systems, you can deploy APIs directly from API Builder to API Management with a single click, streamlining development while ensuring security and consistency.
Celigo’s all-in-one approach simplifies, speeds up, and scales full-lifecycle API management, helping businesses unlock the full potential of their integrations.
