Reverse Engineer a Third-Party API
Problem this workflow solves
You are integrating with an undocumented API and need to understand its structure and behavior.
Steps
- 1Open Tool
Send requests and capture responses
Use the request builder to fire calls against the undocumented API endpoints. Start with GET requests on likely URL patterns and capture the raw responses for analysis.
- 2Open Tool
Format and inspect responses
Paste each raw JSON response into the formatter to pretty-print and explore the nested structure. This reveals field names, data types, and array shapes before you write any parsing code.
- 3Open Tool
Extract query parameters
Paste the full request URLs to parse and list every query parameter the API accepts. This uncovers hidden filters, pagination tokens, and sort options not visible in the response body.
- 4Open Tool
Generate schema from response
Feed a representative JSON response to the schema generator to produce a formal JSON Schema. Use this as the source of truth for field types, required fields, and nested object shapes.
- 5Open Tool
Document endpoints
Compile your findings into structured API documentation covering the endpoint URL, parameters, request format, response schema, and working cURL examples for each endpoint.
What you achieve
You convert a black-box API into a documented, usable integration.
