Hoppscotch

winget install hoppscotch.hoppscotch

Supports individual collection import (not full Postman import).

Importing Collections

• Supports Postman and OpenAPI import.

Adapting the API

Use Secrets and Variables to set API keys and base URLs.

1. Check the properties.
2. Verify or create variables for base URL and API keys.
3. Create or edit an environment.
4. Update environment-specific secrets or variables.

Hoppscotch uses <<>> for variables, not {{}}.

OpenAPI

When importing plain OpenAPI, auth types reset. Use this script to fix the export (default location is Downloads).

import sys
import json
 
file = sys.argv[1]
with open(file, 'r') as f:
    data = json.load(f)
 
folders = data['folders']
allrequests = [rq for folder in folders for rq in folder['requests']]
 
for rq in allrequests:
    rq['auth']['authType'] = 'inherit'
 
with open(f'{file}', 'w') as f:
    json.dump(data, f, indent=4)
 
print(f"Updated {len(allrequests)} requests in {file}")

1. Export the imported OpenAPI specification.
2. Run the script in the Downloads folder.
3. Re-import the updated JSON file.

You may need to change the base URL if it is hardcoded in the OpenAPI spec.
Example (Radarr OpenAPI):

},
  "servers": [
    {
      "url": "<<radarr_base_url>>",

• The URL was replaced with <<radarr_base_url>> so Hoppscotch can resolve it.

Using an API

• Ctrl+Enter sends a request.

Ctrl+Backspace does not delete a word. It clears the response content and cannot be changed.

Supports jq syntax for filtering.
