Integration Agents
Integration Agents are designed to seamlessly connect various service providers to your application.
They support standard API documentation formats such as Postman collections and OpenAPI specifications.
These agents can automatically read API documentation from Postman collections or OpenAPI specifications, understanding the endpoints, request/response formats, and authentication methods.
The Integration Agent begins by loading and then reading the API documentation file, which is typically in JSON or YAML format, to understand its structure and contents.
The agent identifies all the API endpoints defined in the documentation.
An endpoint is typically characterised by a URL path and an HTTP method (GET, POST, PUT, DELETE, etc.), which you can learn more about from our previous article here.
The agent extracts information about the parameters required for each endpoint. This includes query parameters, path parameters, headers, and body content.
It identifies the data types and formats for each parameter, ensuring that requests are correctly structured.
The agent identifies the possible response codes (e.g., 200, 404, 500) for each endpoint.
It parses the structure of the response bodies, noting the expected data types and formats for successful responses and error messages.
If the API requires API keys for authentication, the agent extracts details about how the key should be included in requests (e.g., as a query parameter or header).
The agent can manage tokens, including generating tokens when needed and ensuring they are included in subsequent requests.
The agent performs initial tests by making sample requests to each endpoint to ensure they are correctly set up and operational.
It validates the responses against the expected formats to ensure data integrity and correctness.
Mapping Agents
By leveraging existing software and intelligent algorithms, Mapping Agents eliminate the need for manual coding, significantly reducing the time and effort required for integration.
They utilise Natural Language Processing (NLP) to understand and automate the mapping process.
Using advanced NLP techniques, these agents analyse the structure and semantics of the data from various APIs to create accurate mappings between different data formats.
They map incoming requests and outgoing responses to the appropriate fields in your application, ensuring that data is correctly interpreted and processed.
These NLP techniques include:
- Named Entity Recognition (NER): Mapping agents use NER to recognize and categorise data fields like customer names, addresses, and transaction amounts, facilitating accurate data mapping between APIs.
- Semantic Similarity: Helps mapping agents to align fields from different APIs that have similar meanings but different labels, such as “email” and “contact_email” or “phone_number” and “contact_number”.
- Part-of-Speech Tagging (POS Tagging): Assists in understanding the context and role of each word in a dataset, aiding in the precise mapping of data fields by determining their functions within API responses or requests.
- Dependency Parsing: Mapping agents use dependency parsing to comprehend complex data structures and relationships within JSON or XML responses, ensuring correct mapping of nested fields.
- Tokenization: Enables mapping agents to break down complex field names or descriptions into manageable parts for better analysis and matching of data fields.
Data Handling Agents
Data Handling Agents ensure that your data is consistently accurate and up-to-date by automating data population tasks.
These agents automate the extraction, transformation, and loading (ETL) processes, handling large volumes of data with precision:
- Extraction: Data Handling Agents can connect to various data sources, such as databases, third-party APIs, file systems, and cloud storage services. They use predefined API endpoints and queries to retrieve the required data from these sources. To handle large volumes of data, agents fetch data in batches or chunks, reducing the load on the source systems and ensuring efficient data transfer. They use pagination or other batch processing techniques to systematically retrieve data.
- Transformation: They perform data cleaning tasks such as removing duplicates, handling missing values, and correcting errors. Normalisation involves converting data into a consistent format, such as standardising date formats or unit conversions. Agents map data fields from the source format to the destination schema. Additional information can be added to the data during transformation. You can learn more about data transformations by checking out our previous article here.
- Loading: They establish connections to target systems such as data warehouses, databases, or other storage solutions. The agents use secure methods to transfer data, ensuring the integrity and confidentiality of the data are maintained during transit. For real-time or near-real-time integration, they support incremental loading, which involves only transferring changes since the last load. Data Handling Agents verify that the loaded data matches the transformed data, ensuring accuracy and completeness. They use techniques such as checksums or hash comparisons to validate data integrity.
They continuously monitor and update data, ensuring that the information used across your integrated systems is current and accurate.
Code Generation Agents
Code Generation Agents expedite the development process by producing ready-to-use code tailored to your specific integration needs.
They utilise predefined templates and patterns to ensure that the generated code adheres to best practices and standards.
These agents analyse the integration requirements determined by the integration agents.
For each endpoint, these agents generate code snippets that define the necessary HTTP methods and handle request parameters and responses.
They ensure that the code correctly formats requests and processes responses according to the API specifications.
Code snippets for handling authentication mechanisms (e.g., OAuth 2.0, API keys) are generated.
These snippets ensure that authentication tokens are correctly managed and included in API requests.
Code snippets include error handling routines to manage common issues such as timeouts, invalid responses, and authentication failures.
This ensures robust integration and improves application resilience, which you can learn more about from our previous article here.
Configuration files are essential for setting up and managing integrations.
Code Generation Agents automate the creation of these files based on the requirements.
They define environment-specific settings such as API base URLs, authentication credentials, and other parameters.
They enable seamless switching between development, staging, and production environments.
Agents generate configuration files that specify necessary dependencies, such as libraries and packages required for the integration.
This ensures that all dependencies are correctly installed and managed.
Code Generation Agents also create scripts that automate various tasks involved in the integration process.
These scripts automate tasks such as code compilation, testing, and deployment to servers or cloud platforms.
Agents also create scripts to automate repetitive tasks such as data synchronisation, API request scheduling, and monitoring.
This reduces manual effort and ensures consistent execution of integration tasks.
Server-Side Agents
Server-Side Agents manage API changes, ensuring a seamless transition and maintaining control over integrated endpoints.
They provide developers with tools to control and monitor the integrated endpoints, ensuring that the system remains stable and responsive during transitions.
These agents use polling mechanisms to regularly check for updates in the API documentation of connected services.
The agents employ sophisticated comparison algorithms to detect differences between the current and previous versions of the API documentation.
They look for changes in endpoint structures, parameter lists, response formats, authentication methods, and other critical components.
Upon detecting changes, the agents generate automated alerts and notifications to inform developers about the modifications.
The agents provide detailed reports outlining the specific changes detected, such as new endpoints, parameter modifications, or deprecations.
For minor changes that do not require manual intervention, Server-Side Agents can automatically update the integration configurations.
This includes updating endpoint URLs, adjusting parameter mappings, or modifying request/response handling logic.
After making adjustments, the agents run automated tests to ensure that the integration continues to function correctly.
Conclusion
By developing and bringing together Integration Agents, Mapping Agents, Data Handling Agents, Code Generation, and Server-Side Agents, we have set a new standard for API integration platforms.
We will look to continue innovating, and exploring more ways that autonomous agents can be leveraged to improve the API integration experience.
