DELETE /webhooks/:id

Validating Webhooks

EnergyPrint Webhooks are validated using a BLAKE3 hash of three strings, separated by dots:

  • A shared secret
  • A nonce representing the current epoch time
  • The body of the webhook request

i.e. "{secret}.{nonce}.{body}"

A Nodejs middleware implementation is provided below.

const blake3 = require("blake3")

const validateEpWebhook = async (req, res, next) => {
    const secret = process.env.EP_WEBHOOK_SIGNING_SECRET;

    const {data, nonce, ep_webhook_signature} = req.body;
    const expected_signature = await blake3.hash(
    if (ep_webhook_signature === expected_signature) {
    } else {
        res.status(500).json({success: false});

Getting your secret

Using your API token, getting your shared webhook secret is simple.

GET /webhooks/validate

Resetting your secret

At some point in the future, you may want to reset your shared webhook secret.

POST /webhooks/validate/reset

Responds with the new secret.
