ascend-webhooks: Coding Workflows for AI Agents | OpenAgentSkill

Overview

Receive and verify Ascend webhooks. Use when setting up Ascend webhook handlers, debugging Ascend signature verification (X-Ascend-Signature, HMAC-SHA256), or handling insurance payment events like invoice.paid, payout.paid, and refund.paid.

Ascend Webhooks

Ascend (insurance payments / premium financing) sends webhooks so your app is notified when an event happens — for example when an invoice is paid. Ascend POSTs a JSON payload over HTTPS and signs it with an HMAC-SHA256 signature you must verify before trusting the event.

When to Use This Skill

How do I receive Ascend webhooks?
How do I verify Ascend webhook signatures?
How do I parse the X-Ascend-Signature header?
How do I handle invoice.paid (or payout / refund) events?
Why is my Ascend webhook signature verification failing?

How Ascend Signs Webhooks

Ascend uses a custom Stripe-style HMAC-SHA256 scheme (not Svix, not Standard Webhooks). Two headers are sent:

Header	Example	Purpose
`X-Ascend-Signature`	`t=1696200697,v1=5257a869e7...`	Timestamp + HMAC signature
`X-Ascend-Request-Timestamp`	`1696200697`	Same Unix timestamp (redundant)

The signature is verified by:

Parse X-Ascend-Signature into t (timestamp) and v1 (hex HMAC).
Build the signed string as `${t}:${rawBody}` — the timestamp, a colon, then the raw request body.
Compute HMAC-SHA256(signed_string, webhook_secret) and hex-encode it.
Constant-time compare against v1.

Use the raw request body. Re-serializing the parsed JSON (key reordering, whitespace) changes the bytes and breaks the signature. There is no official Ascend SDK, so every framework below verifies manually.

Verification (core)

const crypto = require('crypto');

// Verify Ascend's "t=<timestamp>,v1=<hex>" signature over "<timestamp>:<rawBody>".
function verifyAscendSignature(rawBody, signatureHeader, secret) {
  const parts = Object.fromEntries(
    signatureHeader.split(',').map((p) => p.split('=').map((s) => s.trim()))
  );
  const { t: timestamp, v1: signature } = parts;
  if (!timestamp || !signature) return false;

  const expected = crypto
    .createHmac('sha256', secret)
    .update(`${timestamp}:${rawBody}`) // colon separator + RAW body
    .digest('hex');

  try {
    return crypto.timingSafeEqual(
      Buffer.from(signature, 'hex'),
      Buffer.from(expected, 'hex')
    );
  } catch {
    return false; // length mismatch = invalid
  }
}

For complete handlers with tests, see examples/express/, examples/nextjs/, examples/fastapi/.

Event Payload Structure

Every event has the same top-level shape. Unlike Stripe, data is the resource object directly (there is no data.object wrapper):

{
  "id": "ajskljfaklsjd0912132",
  "type": "invoice.paid",
  "data": {
    "id": "684c8c8e-75eb-4134-925a-cb3a30f23633",
    "status": "paid",
    "payee": "John Doe Trucking",
    "payer_name": "John Doe",
    "total_amount_cents": 600000,
    "invoice_number": "II2DH1HGHJ",
    "paid_at": "2023-10-01T23:51:37.507Z"
  }
}

Common Event Types

Event	Triggered When
`invoice.created`	An invoice is created
`invoice.processing_payment`	An invoice payment is being processed
`invoice.paid`	An invoice is paid
`invoice.voided`	An invoice is voided
`invoice.marked_overdue`	An invoice is marked overdue
`payout.paying`	A payout is being paid out
`payout.paid`	A payout has been paid
`payout.on_hold`	A payout is placed on hold
`payout.canceled`	A payout is canceled
`payout.failed`	A payout failed
`refund.paid`	A refund has been paid
`refund.cancelled`	A refund was cancelled

Always branch on the type field and handle unknown types gracefully. See references/overview.md for the full list and payloads.

Environment Variables

Variable	Description
`ASCEND_WEBHOOK_SECRET`	The webhook signing secret provided by Ascend

Setup

Ascend webhook registration is manual — there is no self-serve dashboard. Email developers@useascend.com with your organization, environment (sandbox/production), the events you want, and your HTTPS endpoint URL. Ascend returns a webhook signing secret. See references/setup.md.

Local Development

For local webhook testing, run the Hookdeck CLI via npx — no install required:

npx hookdeck-cli listen 3000 ascend --path /webhooks/ascend

No account required — the CLI creates a guest account on first run and provides a local tunnel + web UI for inspecting requests.

# Ascend Webhooks

Ascend (insurance payments / premium financing) sends webhooks so your app is
notified when an event happens — for example when an invoice is paid. Ascend
POSTs a JSON payload over HTTPS and signs it with an HMAC-SHA256 signature you
must verify before trusting the event.

## When to Use This Skill

- How do I receive Ascend webhooks?
- How do I verify Ascend webhook signatures?
- How do I parse the `X-Ascend-Signature` header?
- How do I handle `invoice.paid` (or payout / refund) events?
- Why is my Ascend webhook signature verification failing?

## How Ascend Signs Webhooks

Ascend uses a **custom Stripe-style HMAC-SHA256 scheme** (not Svix, not
Standard Webhooks). Two headers are sent:

| Header | Example | Purpose |
|--------|---------|---------|
| `X-Ascend-Signature` | `t=1696200697,v1=5257a869e7...` | Timestamp + HMAC signature |
| `X-Ascend-Request-Timestamp` | `1696200697` | Same Unix timestamp (redundant) |

The signature is verified by:

1. Parse `X-Ascend-Signature` into `t` (timestamp) and `v1` (hex HMAC).
2. Build the signed string as `` `${t}:${rawBody}` `` — the timestamp, a **colon**, then the **raw request body**.
3. Compute `HMAC-SHA256(signed_string, webhook_secret)` and hex-encode it.
4. Constant-time compare against `v1`.

> **Use the raw request body.** Re-serializing the parsed JSON (key reordering,
> whitespace) changes the bytes and breaks the signature. There is no official
> Ascend SDK, so every framework below verifies manually.

## Verification (core)

```javascript
const crypto = require('crypto');

// Verify Ascend's "t=<timestamp>,v1=<hex>" signature over "<timestamp>:<rawBody>".
function verifyAscendSignature(rawBody, signatureHeader, secret) {
  const parts = Object.fromEntries(
    signatureHeader.split(',').map((p) => p.split('=').map((s) => s.trim()))
  );
  const { t: timestamp, v1: signature } = parts;
  if (!timestamp || !signature) return false;

  const expected = crypto
    .createHmac('sha256', secret)
    .update(`${timestamp}:${rawBody}`) // colon separator + RAW body
    .digest('hex');

  try {
    return crypto.timingSafeEqual(
      Buffer.from(signature, 'hex'),
      Buffer.from(expected, 'hex')
    );
  } catch {
    return false; // length mismatch = invalid
  }
}
```
