Use Case: Parsing out Account Linkages

The following guide will help you read credentials from our API, and surface them in your DApp, and contains code samples in Javascript.
Prerequisites: This assumes that you already have an existing API key, and you've read the Getting Started guide here.
We'll be using the /profile/address/<ETH> endpoint from the Disco API.

To parse out Account Linkages

This also assumes that you have a DApp that uses a wallet connection, to be able to grab the user's ETH Address.

Setup

Make sure you have axios or fetch installed.
npm install axios
Then import it via
import axios from 'axios';

Set up Request Headers

let config = {
method: 'get',
url: 'api.disco.xyz/v1/profile/address/0xE6FF2d91f6EeEe8BDA4bCc562d63c431496FCf2A',
headers: {
'Authorization': 'Bearer <YOUR_API_KEY_HERE>'
}
};

Fetch a user's profile via Disco API

axios.request(config)
.then((response) => {
body = JSON.stringify(response.data)
console.log(body);
})
.catch((error) => {
console.log(error);
});
Using axios in the example above, the response body will contain a JSON array linkages, which will store the Twitter, Discord, and Domain linkages if they exist.

Save Account Linkage

To grab an account linkage, we modify the above request:
axios.request(config)
.then((response) => {
const body = response.data;
if (body["linkages"] && body["linkages"]["twitter"]) {
const twitterAccount = body.linkages.twitter;
console.log("Twitter Account Linked", twitterAccount);
//print to console, or save to display in your DApp
} else {
console.log('No Twitter account linkage found.');
}
...
To check for Discord and/or Domain linkages, replace the "twitter" key with discord or domain:
body["linkages']["domain"].
The following is the JSON body when parsing the result, for a discord account linkage.
"discord": {
"id": "exampleUser#1234",
"host": "discord.com",
"claim": "https://discord.com/channels/9457036257935390/975763597529600041/1047969370840858",
"protocol": "https",
