Overview
The node interacts with the HttpBin API, specifically supporting HTTP GET requests under the "HTTP Verb" resource. It allows users to send HTTP GET requests with customizable query parameters. This is useful for testing and debugging HTTP requests by sending specific query parameters and observing the response from HttpBin, which echoes back the request details.
Practical examples include:
- Testing how an API handles various query parameters.
- Debugging URL encoding issues by inspecting the echoed query parameters.
- Learning about HTTP GET request structures by experimenting with different parameters.
Properties
| Name | Meaning |
|---|---|
| Type of Data | Selects the type of data to send; currently only "Query" (query parameters) is supported. |
| Query Parameters | Key-value pairs representing the query parameters to be sent with the GET request. Each pair consists of a "Key" (parameter name) and a "Value" (parameter value). |
Output
The node outputs JSON data containing the response from the HttpBin API. For a GET request with query parameters, the output JSON will typically include an object reflecting the received query parameters under a field like args. This allows users to verify that their query parameters were correctly sent and received.
No binary data output is indicated.
Dependencies
- The node requires access to the public HttpBin API at
https://httpbin.org. - No mandatory credentials are required, but an optional API key credential can be configured if needed.
- Network connectivity to the HttpBin service is necessary.
Troubleshooting
- Common Issues:
- Network errors or timeouts if the HttpBin service is unreachable.
- Incorrectly formatted query parameters may not appear as expected in the response.
- Error Messages:
- HTTP errors returned by HttpBin (e.g., 4xx or 5xx status codes) indicate issues with the request or server.
- Validation errors if required query parameter keys or values are missing.
- Resolutions:
- Verify network connectivity and HttpBin service availability.
- Ensure all query parameter keys and values are properly set and non-empty.
- Check for typos or invalid characters in query parameters.
