Elliptic SDK for Node.js

Installation

$3

Install the SDK using npm:

``shell npm install elliptic-sdk --save`

`$3`

Usage of the SDK requires your Elliptic API keys, which would be insecure to embed in a browser application. For this reason, we do not advise calling our API from browser applications.

`Usage`

The SDK provides an instance of the popular Axios HTTP client, adding the necessary steps to authenticate each request using your Elliptic API key and secret.

`javascript const { AML } = require("elliptic-sdk");

// clientis an instance of axios const { client } = new AML({ key: "YOUR_ELLIPTIC_API_KEY", secret: "YOUR_ELLIPTIC_API_SECRET", });

client.get("/v2/analyses").then((res) => console.log(res.data));`

`Webhook signature verification`

Elliptic signs the webhook events it sends to your endpoint, allowing you to validate that they were not sent by a third-party. You can use theWebhookRequestVerifierclass to verify the signature of a webhook request:

`javascript const express = require("express"); const bodyParser = require("body-parser"); const { WebhookRequestVerifier } = require("elliptic-sdk");

const port = 1337;

const verifier = new WebhookRequestVerifier({ trustedPublicKey: "", expectedEndpointId: "", });

const app = express();

const rawBodyMiddleware = bodyParser.raw({ type: () => true });

app.post("/", rawBodyMiddleware, (req, res) => { try { verifier.verify({ reqBody: req.body, webhookIdHeader: req.headers["webhook-id"], webhookTimestampHeader: req.headers["webhook-timestamp"], webhookSignatureHeader: req.headers["webhook-signature"], }); // Verification succeeded res.status(200); res.send("OK"); } catch (err) { // Verification failed console.error(err.message); res.status(401); res.send("Unauthorized"); } });

app.listen(port, () => { console.log(Server is running on port ${port}); });``

Usage

The SDK provides an instance of the popular Axios HTTP
client, adding the necessary steps to
authenticate each request using your Elliptic API key and secret.

 javascript
const { AML } = require("elliptic-sdk");

// client

 is an instance of axios
const { client } = new AML({
  key: "YOUR_ELLIPTIC_API_KEY",
  secret: "YOUR_ELLIPTIC_API_SECRET",
});

client.get("/v2/analyses").then((res) => console.log(res.data));

Webhook signature verification

Elliptic signs the webhook events it sends to your endpoint, allowing
you to validate that they were not sent by a third-party. You can use
the

WebhookRequestVerifier

 class to verify the signature of a webhook
request:

 javascript
const express = require("express");
const bodyParser = require("body-parser");
const { WebhookRequestVerifier } = require("elliptic-sdk");

const port = 1337;

const verifier = new WebhookRequestVerifier({
  trustedPublicKey: "",
  expectedEndpointId:
    "",
});

const app = express();

const rawBodyMiddleware = bodyParser.raw({ type: () => true });

app.post("/", rawBodyMiddleware, (req, res) => {
  try {
    verifier.verify({
      reqBody: req.body,
      webhookIdHeader: req.headers["webhook-id"],
      webhookTimestampHeader: req.headers["webhook-timestamp"],
      webhookSignatureHeader: req.headers["webhook-signature"],
    });
    // Verification succeeded
    res.status(200);
    res.send("OK");
  } catch (err) {
    // Verification failed
    console.error(err.message);
    res.status(401);
    res.send("Unauthorized");
  }
});

app.listen(port, () => {
  console.log(

Server is running on port ${port}

);
});
