Enhancing API Documentation with Multiple Request Body Examples in Apidog

In the rapidly evolving landscape of API development, clear and comprehensive documentation serves as the foundation for successful implementation and adoption. One of the most significant challenges developers face is understanding how to structure request bodies for different scenarios. Apidog addresses this challenge through its robust support for multiple request body examples, a feature that aligns perfectly with OpenAPI specifications while enhancing the overall developer experience.

Multiple request body examples provide developers with concrete representations of how API requests should be structured across various business scenarios. Rather than relying on a single generic example, API consumers can now access tailored examples that demonstrate specific use cases, error conditions, or data variations. This capability is particularly valuable when working with complex APIs that handle diverse data structures or when onboarding new team members who need clear guidance on API usage.

The implementation of multiple request body examples in Apidog offers several key advantages:

• Enhanced clarity for API consumers through contextual examples that demonstrate different business scenarios
• Improved testing efficiency by allowing quick switching between predefined request examples during debugging
• Stronger OpenAPI compliance with proper export of example objects following OAS 3.0/3.1 specifications
• Reduced documentation effort through streamlined example management within a single interface

For API providers, this feature eliminates the need to document various request scenarios in separate locations, centralizing all examples within the API documentation itself. This approach not only saves time but also ensures that examples remain synchronized with the API specification as it evolves.

How to Configure Request Body Examples in Apidog for OpenAPI Compatibility

Apidog's implementation of request body examples has been designed with OpenAPI specifications in mind, ensuring that all configured examples can be properly exported and consumed by other tools in the API ecosystem. The configuration process is straightforward yet powerful, allowing for detailed customization of each example.

To begin working with multiple request body examples in Apidog, users must ensure they are using version 2.7.0 or higher. The feature supports configuring examples for request bodies of JSON, XML, Raw, and MsgPack types, covering the most common data formats used in modern API development.

The configuration process follows these steps:

1. Navigate to the endpoint documentation that requires multiple request body examples
2. Locate the Request Body section within the Edit page
3. Click the "+ Add" button to create a new request body example
4. Configure the example details, including:

• Example Name: A descriptive label (defaults to "Example 1", "Example 2", etc. if left blank)
• Example Value: The actual JSON, XML, or other formatted data
• Description: Markdown-supported explanation of the example's purpose or scenario
• OAS Key: The identifier used when exporting to OpenAPI specifications
• OAS Extensions: Custom fields that will be preserved during export

Each of these configuration options plays a specific role in ensuring that examples are both useful for human readers and properly structured for machine consumption through OpenAPI specifications.

The OAS Key deserves special attention as it controls how examples are identified in exported specifications. When provided, this key becomes the field name within the examples object. If left blank, Apidog automatically assigns sequential numbers as identifiers. This flexibility allows for both human-readable example names and compliance with OpenAPI naming conventions.

Similarly, OAS Extensions enable the addition of custom metadata to examples, which can be valuable for tools that consume OpenAPI specifications and need additional context about each example. These extensions are preserved during export, ensuring that no information is lost when sharing specifications with other systems.

Step-by-Step Guide to Adding Multiple Request Body Examples with Apidog

The process of adding and managing multiple request body examples in Apidog follows a logical workflow designed to minimize friction while maximizing flexibility. This step-by-step guide walks through the entire process from creation to usage.

5. In the dialog that appears, provide the following information:

• A descriptive name for your example (e.g., "Standard Request")
• The actual example value in the appropriate format (JSON, XML, etc.)
• An optional description explaining the purpose or context of this example
• An optional OAS Key if you need specific naming in exported specifications
• Any custom OAS Extensions as JSON key-value pairs

Step 2: Adding Additional Examples for Different Scenarios

After creating your first example, you can add more examples to cover different business scenarios:

1. Click the "+ Add" button again to create another example
2. Provide a distinct name that clearly identifies the scenario (e.g., "Error Case")
3. Enter the example value representing this specific scenario
4. Add a detailed description explaining when this example would be used
5. Configure the OAS Key and Extensions as needed
6. Repeat this process for all relevant scenarios your API might encounter

Step 3: Organizing and Prioritizing Your Examples

Apidog displays examples according to a specific priority order:

1. Examples with names are displayed before unnamed examples
2. Examples with OAS Keys are prioritized over those without
3. Examples without names or OAS Keys are ordered by their serial numbers

To ensure your most important examples appear prominently:

1. Assign clear, descriptive names to critical examples
2. Provide OAS Keys for examples that need specific identification in exports
3. Review the display order in both the documentation and debugging views

Step 4: Extracting Request Parameters as Examples

Apidog also allows you to create examples from actual debugging sessions:

1. Navigate to the "Run" page of your endpoint
2. Configure the request body with the values you want to save
3. Click the Extract button and select Extract to "Request Example"

5. Choose whether to overwrite an existing example or create a new one

6. The current debugging values will be automatically filled into the example

This feature is particularly valuable during API development when you've found a working request structure that you want to preserve for future reference or documentation.

Leveraging Request Body Examples for Efficient API Testing and Debugging

The true power of multiple request body examples becomes apparent during the testing and debugging phases of API development. Apidog's implementation allows developers to quickly switch between different examples without manually reconfiguring request bodies, significantly accelerating the testing process.

When debugging an endpoint with multiple request body examples:

1. Navigate to the "Run" page of the endpoint documentation
2. Locate the "Auto-generate" section in the request configuration
3. Click the dropdown menu to view all available request body examples
4. Select the desired example to automatically populate the request body
5. Send the request to test the endpoint with the selected example

This workflow eliminates the need to manually copy and paste different request structures during testing, reducing the potential for errors and saving valuable development time. Developers can rapidly cycle through different scenarios, testing how the API responds to various input combinations without leaving the Apidog interface.

For more advanced testing needs, Apidog provides additional options accessible through the dropdown icon next to "Auto-generate":

• EXAMPLES: Select from predefined request body examples

4. Review exported specifications to verify that examples are properly formatted

The exported OpenAPI specification will include all examples in a structure similar to:

"examples": {
  "example1": {
    "value": {
      "name": "Blake Keeling",
      "id": "165061",
      "email": "Blake.Keeling@gmail.com"
    },
    "summary": "example1",
    "description": "This is example 1"
  },
  "example2": {
    "value": {
      "name": "Jolie Kutch",
      "id": "138164",
      "email": "Jolie_Kutch@hotmail.com"
    },
    "summary": "example 2",
    "description": "This is example 2"
  }
}

This structure aligns with the OpenAPI specification for request body examples, ensuring that all information is preserved and properly formatted for consumption by other tools.
