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.
This also assumes that you have a DApp that uses a wallet connection, to be able to grab the user's ETH Address.
Make sure you have axios or fetch installed.
npm install axiosThen import it via
import axios from 'axios';
let config = {
method: 'get',
url: 'api.disco.xyz/v1/profile/address/0xE6FF2d91f6EeEe8BDA4bCc562d63c431496FCf2A',
headers: {
'Authorization': 'Bearer <YOUR_API_KEY_HERE>'
}
};
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.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",
