Overview
This 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, inspecting how query parameters are handled by a server, or simply retrieving data from endpoints that accept query parameters.
Practical examples include:
- Sending a GET request with specific query parameters to test an API endpoint.
- Debugging how query parameters are encoded and received by a server.
- Fetching filtered or paginated data from an API that uses query 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. |
The "Query Parameters" property allows multiple key-value pairs where each key is the name of the query parameter and the value is its corresponding string value.
Output
The node outputs JSON data returned from the HttpBin API in response to the GET request. The output will typically contain details about the request as interpreted by HttpBin, including the query parameters sent.
If the API returns binary data (not typical for this node's GET operation), it would be available in the binary output field, but this node primarily deals with JSON responses.
Dependencies
- Requires access to the public HttpBin API at
https://httpbin.org. - Optionally can use an API authentication token if configured, but it is not required.
- No additional external dependencies beyond standard HTTP request capabilities.
Troubleshooting
Common issues:
- Incorrectly formatted query parameters may lead to unexpected API responses.
- Network connectivity problems can cause request failures.
- If the API changes or is unavailable, the node will fail to retrieve data.
Error messages:
- HTTP errors (e.g., 4xx or 5xx status codes) indicate issues with the request or server.
- Timeout errors suggest network or server responsiveness problems.
Resolutions:
- Verify query parameter keys and values are correctly set.
- Check internet connection and API availability.
- Review API documentation for any changes in expected parameters.
