parsons[VAN] : Add NGP Introspection Endpoint

[engelhartrueben]

I recently have come across this tool https://docs.ngpvan.com/reference/introspection by NGP VAN that has helped us check both the connection and the key permissions. It has been helpful when checking if a key has access to MyCampaigns, but not MyVoters, for instance.

Detailed Description

Add Introspection call to Parsons API. This method would take in the username and API Key, handle the conversion to base64, and make the introspection call to VAN. The response would return the JSON object, regardless of success or failure.

Context

This is important because it allows for a quick check of connection and permissions within a given application.

Possible Implementation

The script on the VAN Documentation suffices for my local setup (with some tweaks), but am not super familiar with the this repository.

import requests

url = "https://api.securevan.com/v4/apiKeyProfiles"

headers = {
     "accept": "application/json",
     "authorization": "Basic ****some base64 string ==****"
}

response = requests.get(url, headers=headers)

print(response.text)

Response:

{
    "items": [
        {
            "databaseName": "SmartVAN Massachusetts",
            "hasMyVoters": true,
            "hasMyCampaign": true,
            "committeeName": "People for Good",
            "apiKeyTypeName": "Custom Integration",
            "keyReference": "1234",
            "userFirstName": "peopleforgood",
            "userLastName": "api",
            "username": "peopleforgood.api",
          	"userId": 4321
        }
    ],
    "nextPageLink": null,
    "count": 1
}

Priority

Low priority, but helpful none the less (:
