# Building with Polygon ID Platform APIs
by Steph [oceans404](https://twitter.com/0ceans404)
Polygon ID Platform APIs empower you to **programatically**
- Onboard to Polygon ID by creating an organization and issuer
- Create reusable schema templates
- Generate claims offers (links to QR codes) to issue to users
- & so much more... check out the official [Polygon ID Platform API docs](https://0xpolygonid.github.io/tutorials/issuer/platform-api/introduction/) for the full list of APIs
This repo walks through programatically creating an Issuer in Node.js by creating an account (org and issuer), writing a claim schema, and generating issuable claims, sometimes called offers. You can use the same flow to build your own frontend Issuer website -- check out my repo: [generate-frontend-polygon-id-issuer](https://github.com/oceans404/generate-frontend-polygon-id-issuer)
## Repo setup
0. Pre-req: [Install Node.js](https://nodejs.org/en/download/)
1. Star and clone repo `git clone https://github.com/oceans404/node-polygon-id-platform-apis`
2. cd into repo `cd node-polygon-id-platform-apis`
3. Create a .env file: `cp .env.example .env;`
- Within the .env file, update `POLYGON_ID_EMAIL` to your email. You will only be able to create one org account per email. I used the [+ sign in my email](https://people.cs.rutgers.edu/~watrous/plus-signs-in-email-addresses.html) to run multiple tests. ex: myemail@gmail.com, myemail+test0@gmail.com, myemail+test1@gmail.com, myemail+test2@gmail.com
- Within the .env file, update `POLYGON_ID_PASSWORD` with a strong password (needs lowercase, uppercase, numbers, and special chars).
## Polygon ID Onboarding (Create Org and Issuer)
Before you can create and issue claims, you must complete the onboarding flow. Onboard to Polygon ID by creating an Organization account either programatically or within the [Polygon ID Platform UI](https://platform-test.polygonid.com/sign-up).
### Option 1: Onboard within the Polygon ID Platform UI
#### 1. Sign up
Visit https://platform-test.polygonid.com/sign-up to sign up for an organization account to match the email and password in your `.env` file.
#### 2. Verify your org account
Click the link sent to your email. You may have to copy paste the full link into your browser because it has a period in it.
#### 3. Create your org's "issuer" with a name and optional details.
### Option 2: Onboard Programatically
#### 1. Create An Organization Account
Run `node api/createOrg.js`
```js
// Status: 201
// Body: {
// createdAt: '2022-11-28T22:53:54.537388Z',
// email: 'myemail+test@icloud.com',
// id: 'a460c501-e936-41f6-8af9-a29035ecf2db',
// modifiedAt: '2022-11-28T22:53:54.537388Z',
// type: 'OWNER',
// verified: false
// }
```
[Create Org endpoint docs](https://0xpolygonid.github.io/tutorials/issuer/platform-api/onboarding-orgs/apis/#create-org)
#### 2. Sign-in to an Organization Account
Run `node api/signinOrg.js`
After you run the orgs sign in script, your generated JWT token is written to `token.js`
[Sign In to Org endpoint docs](https://0xpolygonid.github.io/tutorials/issuer/platform-api/onboarding-orgs/apis/#sign-in)
#### 3. Activate Organization Account
Run `node api/ActivateAccount.js`
```js
// generates a new token that is saved to the file
// {
// token: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2Njk4Mjk1MDksImp0aSI6ImEwYmVmOGFlLWU3YTAtNDU2NC1hZDg2LTk5MzE0ZTE5YmY1YyIsImlhdCI6MTY2OTc0MzEwOSwibmJmIjoxNjY5NzQzMTA5LCJzdWIiOiIyNzJkNjE2Zi01YjIzLTQwMjQtOTFhNi01MzIyMGQ4NzIzNzEiLCJzY29wZSI6ImFwaSIsImFjY291bnQiOnsidmVyaWZpZWQiOnRydWUsIm9yZ2FuaXphdGlvbiI6bnVsbCwicm9sZSI6Ik9XTkVSIiwiZW1haWwiOiJzdGVwaGFuaWVvcnBpbGxhK3Rlc3QyQGljbG91ZC5jb20ifX0.Xyzci_oohDatcwBr1oxIvK_fJ_JGAiCABLHS98Yopzc'
// }
```
Once you've activated your account, you generate a new token that is written to `token.js`
[Activate Account endpoint docs](https://0xpolygonid.github.io/tutorials/issuer/platform-api/onboarding-orgs/apis/#activate-account)
#### 4. Create an Issuer
Update the issuerInfo object in `yourData.js` to name your Issuer (must be unique across Polygon ID ecosystem!). You'll be able to update these fields later within the [Polygon ID Platform UI](https://platform-test.polygonid.com/).
Run `node api/createIssuer.js`
```js
// Status: 201
// Body: {
// createdAt: '2022-11-29T18:52:20.506164Z',
// did: '115p1w77jT4Hs8x7sx4eMmKdyb9tzMsqngmYtBLKUj',
// displayName: 'my super legit issuer',
// id: 'e68a824f-d493-42df-9022-5d5b9bdad548',
// legalName: 'gm inc.',
// logo: '',
// modifiedAt: '2022-11-29T18:52:20.506164Z',
// ownerEmail: 'myemail+test@icloud.com',
// region: 'USA',
// slug: 'my-super-legit-issuer'
// }
```
[Create Issuer endpoint docs](https://0xpolygonid.github.io/tutorials/issuer/platform-api/issuer/apis/#create-issuer)
#### 5. Refresh Token
Run `node api/refreshToken.js`
[Refresh Token endpoint docs](https://0xpolygonid.github.io/tutorials/issuer/platform-api/onboarding-orgs/apis/#refresh-token)
## Create a Schema
A Schema is a reusable template that defines the structure of claims by typing attributes. You can either [create a schema within the Polygon Platform UI](https://platform-test.polygonid.com/claiming/create-schema) or programatically by following the instructions below.
#### 1. Define your schema structure
Update schemaStructure within `yourData.js`. Schemas must have unique names and up to 2 named attributes of type boolean, date, or number. If you set mandatoryExpiration to true, you'll need to add an expiration date later while issuing claims.
#### 2. Sign in if you onboarded through the UI
Run `node api/signinOrg.js` to generate a token.js file
#### 3. Run `node api/createSchema.js`
Here's my result. I saved the schemaURL s3 file to `resultingS3SchemaURL.json` for reference
```js
// Status: 201
// Body: {
// active: true,
// attributes: [
// {
// description: 'Is pineapple an acceptable pizza topping, yes or no?',
// name: 'LikesPineappleOnPizza',
// type: 'boolean'
// },
// {
// description: 'Number of animal friends (cats, dogs, birds, etc.) you own.',
// name: 'PetCount',
// type: 'number'
// }
// ],
// createdAt: '2022-11-29T22:32:23.962388Z',

// mandatoryExpiration: false,

// technicalName: '',
// version: '1.1'
// }
```
[Create Schema endpoint docs](https://0xpolygonid.github.io/tutorials/issuer/platform-api/schemas/apis/#create-schema)
## Create a Claim Offer
#### 1. Set the schema id for your claim
Find the claimOffer object within `yourData.js`. Update the schemaId property to your schema id so the claim follows that schema's template. The schema id is the `id` field logged when you created a schema. Alternatively you can find out a schema's id on the ["Created Schemas" page](https://platform-test.polygonid.com/claiming/created-schemas) of Polygon ID Platform by clicking the schema and grabbing the id from the schemaID parameter in the url.
#### 2. Create an array of attribute keys and values for your offer
Update the attributes array within the claimOffer object in `yourData.js` so that there is one attribute object per attribute from the schemaStructure you created. The attributeKey property should match the name from the schemaStructure. The attributeValue should be a number (0 falsy, 1 truthy for booleans).
#### 3. run `node api/createClaim.js` to print your claim link
Note: this calls both the create claim and create qr code of offer APIs

// Body: {
// attributeValues: [
// { attributeKey: 'LikesPineappleOnPizza', attributeValue: 1 },
