Admin SDK

Note: Admin SDK is meant for server-deployment only. Do not place ID or Secret in the browser

Initialize Admin Client

const netvoteApis = require("@netvote/netvote-api-sdk")

const nv = netvoteApis.initAdminClient(
    process.env.NETVOTE_API_KEY, 
    process.env.NETVOTE_API_ID, 
    process.env.NETVOTE_API_SECRET, 
)

Create Election

let metadata = await nv.SaveToIPFS({
	"type": "basic",
	"ballotTitle": "2020 Election",
	"ballotLocation": "NYC",
	"ballotDate": "",
	"ballotImage": "",
	"featuredImage": "https://netvote.io/wp-content/uploads/2018/03/roswell-ga.jpg",
	"ballotInformation": "Some information",
	"ballotGroups": [{
		"groupTitle": "Decision Types",
		"ballotSections": [{
			"type": "multiple",
			"maxSelect": 2,
			"minSelect": 1,
			"sectionTitle": "Governor",
			"sectionTitleNote": "Choose 1 or 2 choices",
			"ballotItems": [{
				"itemTitle": "John Smith",
				"itemDescription": "Democratic Party"
			}, {
				"itemTitle": "Sally Gutierrez",
				"itemDescription": "Republican Party (incumbent)"
			}, {
				"itemTitle": "Tyrone Williams",
				"itemDescription": "Independent"
			}]
		}, {
			"type": "single",
			"sectionTitle": "Proposition 33",
			"sectionTitleNote": "Do you support Proposition 33?",
			"ballotItems": [{
				"itemTitle": "Yes"
			}, {
				"itemTitle": "No"
			}]
		}, {
			"type": "ranked",

			"sectionTitleNote": "Choose your favorite color (1 is highest)",
			"ballotItems": [{
				"itemTitle": "Red"
			}, {

			"totalPoints": 9,
			"sectionTitle": "Tax Commissioner",
			"sectionTitleNote": "Allocate Points",
			"ballotItems": [{
				"itemTitle": "Doug Hall",
				"itemDescription": "(incumbent)"
			}, {
				"itemTitle": "Emily Washington"
			}]
		}]
	}]
});

let job = await nv.CreateElection({
    autoActivate: false,
    continuousReveal: false,
    metadataLocation: metadata.hash,
    requireProof: true,
    allowUpdates: true,
    netvoteKeyAuth: true,
    network: "netvote"
});

let finished = await nv.PollJob(job.jobId, 60000);

let electionId = finished.txResult.electionId;

Create a Voter Key

// example logic for base64(sha256(key)) 
const sha256Hash = (str) => {
    let hash = crypto.createHash("sha256")
    hash.update(str);
    return hash.digest().toString("base64");
}

// hash key
let voterKey = "secretKey"
let hashedKey = sha256Hash(voterKey)

let res = await nv.AddVoterKeys(electionId, {hashedKeys: [hashedKey]});

console.log(res.count) // 1 

Activate / Resume Election

await nv.ActivateElection(electionId);

Stop Election

await nv.StopElection(electionId);

Close Election (Permanent)

await nv.CloseElection(electionId);

Client SDK

This can be initialized in a browser using a stack like Browserify

Initialize Voter/Public Client

const netvoteApis = require("@netvote/netvote-api-sdk")

const publicNv = netvoteApis.initVoterClient(
    process.env.NETVOTE_API_KEY, 
)

Get Anonymous Voter Auth Token

// voterToken distributed via string
let tokenReponse = await publicNv.GetJwtToken(electionId, voterKey)
let token = tokenResponse.token;

Get Anonymous Voter Auth Token QR

// voterToken distributed via string or QR
let tokenReponse = await publicNv.GetJwtTokenQR(electionId, voterKey)

// token qr is data URL object with {electionId: electionId, token: jwtToken}
document.getElementById("yourimage").src = tokenReponse.qr;

Cast Vote

let voteObject = {
    ballotVotes: [
        {
            choices: [
                {
                    indexSelections: {
                        indexes: [0, 1]     // select first and second choice
                    }
                },
                {
                    selection: 1            // select the second choice
                },
                {
                    pointsAllocations: {
                        points: [2,1,3]     // index is choice, value is rank (1 is highest)
                    }
                },
                {
                    pointsAllocations: {
                        points: [3,6]       // these are points, more is higher
                    }
                }
            ]
        }
    ]
}
let job = await publicNv.CastSignedVote(electionId, token, voteObject)

// poll for 60 seconds
let res = await publicNv.PollJob(job.jobId, 60000);

if(res.txStatus === "complete"){
    // everything is good
} else {
    // an error occured, or vote is a duplicate
}

REST API

Authentication

There are two required headers:

x-api-key: APIKEY
Authorization: Basic base64(ID:SECRET)

For example, for values APKEY=abc123, ID=testid, and SECRET=testsecret, the headers are:

x-api-key: abc123
Authorization: Basic dGVzdGlkOnRlc3RzZWNyZXQK
