This document outlines the detailed architectural plan for the "API Documentation Generator." This plan focuses on creating a robust, extensible, and maintainable system capable of generating professional API documentation from various sources, including endpoint descriptions, request/response examples, authentication guides, and SDK usage examples.
The primary goal of the API Documentation Generator is to automate the creation of high-quality, comprehensive, and user-friendly API documentation. It aims to reduce manual effort, ensure consistency, and support multiple output formats and input sources.
Key Objectives:
The API Documentation Generator will follow a modular, pipeline-based architecture, consisting of distinct stages: Input Parsing, Internal Representation, Processing/Enrichment, and Output Generation.

This layer is responsible for ingesting API definitions from various sources and converting them into a standardized internal data model.
This is the central, technology-agnostic representation of the API. It acts as the canonical source of truth for all API information within the generator. This model will be highly structured and normalized.
/users/{id}).* Method Object: Represents an HTTP method for an endpoint (GET, POST, PUT, DELETE).
* Parameters: Path, query, header, cookie parameters (name, type, required, description, schema).
* Request Body: Content types, schemas, examples.
* Responses: Status codes, descriptions, headers, content types, schemas, examples.
* Security Requirements: Specific security schemes applicable to this method.
This layer takes the raw internal data model and enriches it with additional information or transformations required for high-quality documentation.
* Schema-to-Example Converter: Automatically generates realistic JSON/XML examples from defined schemas.
* Example Injector: Integrates user-provided examples directly into the documentation.
* Language-Specific Templates: Utilizes templates (e.g., for Python, JavaScript, cURL, Ruby) to generate code snippets demonstrating how to interact with each endpoint, including authentication.
* Dynamic Parameter Insertion: Fills in example values for parameters into the generated code.
$ref references within the internal data model to provide a fully dereferenced view for documentation generation, ensuring all schema details are readily available.This component is responsible for combining the processed internal data model with predefined templates to render the final documentation structure.

openapi.yaml, postman_collection.json). * Authentication Handler creates authentication guides.
* Example Generator produces or integrates request/response examples.
* SDK Usage Example Generator creates code snippets.
* Schema Resolver dereferences schemas.
To ensure robustness, extensibility, and good community support, the following technology stack is recommended:
* PyYAML / json for basic file handling.
* openapi-spec-validator (Python) or swagger-parser (Node.js) for OpenAPI parsing and validation.
* Custom parsers for Postman Collections.
The proposed architecture includes several points of extensibility for future features:
This architectural plan provides a solid foundation for building a powerful and flexible API Documentation Generator. The modular approach ensures that the system can evolve to meet future requirements and integrate with a wide array of tools and workflows.

We are pleased to present the comprehensive API Documentation for the PantheraHive Workflow API. This document serves as a complete guide for developers to integrate with our powerful workflow automation platform, enabling programmatic access to manage, execute, and monitor your workflows.
Our goal is to provide clear, concise, and actionable information, ensuring a smooth development experience.
The PantheraHive Workflow API provides a robust set of endpoints to programmatically interact with your workflows. You can manage workflow definitions, trigger executions, retrieve status updates, and integrate PantheraHive's automation capabilities directly into your applications.
Key Features:
Base URL:
All API requests should be prefixed with the following base URL:
https://api.pantherahive.com/v1
The PantheraHive Workflow API supports two primary methods for authentication: API Keys and OAuth 2.0.
For quick integration and server-to-server communication, you can use an API Key.
How to Obtain an API Key:
How to Use an API Key:
Include your API Key in the Authorization header of every request, prefixed with Bearer.
Example:
Authorization: Bearer YOUR_API_KEY
cURL Example:
curl -X GET \
https://api.pantherahive.com/v1/workflows \
-H 'Authorization: Bearer YOUR_API_KEY'
For applications requiring user consent and delegated access (e.g., third-party integrations), OAuth 2.0 is the recommended method.
Supported Grant Types:
OAuth 2.0 Flow (Authorization Code Grant):
* Log in to your PantheraHive dashboard.
* Navigate to "Settings" -> "Applications" and register a new application.
* You will receive a client_id and client_secret. Configure your redirect_uri.
Redirect your user to the PantheraHive authorization URL:
GET https://api.pantherahive.com/oauth/authorize
?response_type=code
&client_id=YOUR_CLIENT_ID
&redirect_uri=YOUR_REDIRECT_URI
&scope=workflow:read workflow:write workflow:execute
&state=OPTIONAL_STATE_VALUE
* scope: Define the permissions your application needs (e.g., workflow:read, workflow:write, workflow:execute).
After the user grants permission, they will be redirected to your redirect_uri with an authorization_code. Exchange this code for an access_token and refresh_token:
curl -X POST \
https://api.pantherahive.com/oauth/token \
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'grant_type=authorization_code&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&code=AUTHORIZATION_CODE&redirect_uri=YOUR_REDIRECT_URI'
Response Example:
{
"access_token": "YOUR_ACCESS_TOKEN",
"token_type": "Bearer",
"expires_in": 3600,
"refresh_token": "YOUR_REFRESH_TOKEN",
"scope": "workflow:read workflow:write workflow:execute"
}
Include the access_token in the Authorization header, prefixed with Bearer, similar to API Key authentication.
Example:
Authorization: Bearer YOUR_ACCESS_TOKEN
When your access_token expires, use the refresh_token to obtain a new one:
curl -X POST \
https://api.pantherahive.com/oauth/token \
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'grant_type=refresh_token&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&refresh_token=YOUR_REFRESH_TOKEN'
The PantheraHive Workflow API uses standard HTTP status codes to indicate the success or failure of an API request. In case of an error, the API will return a JSON object containing details about the error.
| Status Code | Meaning | Description |
| :---------- | :--------------------------- | :-------------------------------------------------------------------------- |
| 200 OK | Success | The request was successful. |
| 201 Created | Resource Created | The request resulted in a new resource being created. |
| 204 No Content | No Content | The request was successful, but there is no content to return (e.g., DELETE). |
| 400 Bad Request | Invalid Request | The request was malformed or missing required parameters. |
| 401 Unauthorized | Authentication Required | Authentication credentials were missing or invalid. |
| 403 Forbidden | Insufficient Permissions | The authenticated user does not have permission to perform the action. |
| 404 Not Found | Resource Not Found | The requested resource does not exist. |
| 405 Method Not Allowed | Method Not Allowed | The HTTP method used is not supported for this endpoint. |
| 429 Too Many Requests | Rate Limit Exceeded | You have sent too many requests in a given amount of time. |
| 500 Internal Server Error | Server Error | An unexpected error occurred on the server. |
When an error occurs, the API will return a JSON object with the following structure:
{
"code": "ERROR_CODE_STRING",
"message": "A human-readable description of the error.",
"details": [
{
"field": "parameter_name",
"message": "Specific reason for the parameter error."
}
],
"trace_id": "UNIQUE_REQUEST_IDENTIFIER"
}
Example 400 Bad Request Response:
{
"code": "INVALID_INPUT",
"message": "The request body contains invalid data.",
"details": [
{
"field": "name",
"message": "Workflow name cannot be empty."
},
{
"field": "steps[0].action",
"message": "Invalid action type 'unknown_action'."
}
],
"trace_id": "a1b2c3d4e5f6g7h8i9j0"
}
To ensure fair usage and maintain API stability, the PantheraHive Workflow API implements rate limiting.
429 Too Many Requests HTTP status code.The following HTTP headers are included in every API response to help you manage your request rate:
X-RateLimit-Limit: The maximum number of requests you can make in the current window.X-RateLimit-Remaining: The number of requests remaining in the current window.X-RateLimit-Reset: The time (in UTC epoch seconds) when the current rate limit window resets.Example Headers:
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1678886400
This section details all available API endpoints, their methods, parameters, and provides request/response examples.
Throughout the API, a workflow object generally adheres to the following structure:
{
"id": "wf_abcdef123456",
"name": "My First Workflow",
"description": "A simple workflow to process user input.",
"status": "active",
