Alchemy Webhooks

When to Use This Skill

  • How do I receive Alchemy webhooks?
  • How do I verify Alchemy webhook signatures (the X-Alchemy-Signature header)?
  • How do I handle ADDRESS_ACTIVITY, NFT_ACTIVITY, or GRAPHQL events?
  • Why is my Alchemy webhook signature verification failing?
  • How do I set up Alchemy Notify webhooks for onchain activity?

Verification (core)

Alchemy signs every webhook with HMAC-SHA256 over the raw request body, hex-encoded, in the X-Alchemy-Signature header. There is no sha256= prefix and no timestamp — just the hex digest. The key is the per-webhook signing key (copied from the top-right of that webhook's detail page in the Notify dashboard, or fetched via the Notify API), not your app's Auth Token.

The alchemy-sdk npm package manages webhook CRUD but does not verify signatures — implement HMAC yourself. Always compute the HMAC over the raw body; a re-serialized JSON body will not match.

const crypto = require('crypto');

function verifyAlchemySignature(rawBody, signature, signingKey) {
  if (!signature) return false;
  const digest = crypto
    .createHmac('sha256', signingKey)
    .update(rawBody, 'utf8')   // rawBody: exact bytes/string received, never re-stringified JSON
    .digest('hex');
  try {
    return crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(digest));
  } catch {
    return false; // length mismatch = invalid
  }
}

For complete handlers with route wiring, event dispatch, and tests, see:

Common Event Types

The webhook type field identifies the event. Alchemy webhooks are scoped per chain/network.

TypeTriggered When
ADDRESS_ACTIVITYETH/ERC-20/ERC-721/ERC-1155 transfers involving tracked addresses
NFT_ACTIVITYERC-721/ERC-1155 transfers for tracked NFT contracts
GRAPHQLA Custom Webhook GraphQL query matches new onchain data

These three are the values the Notify API's create-webhook endpoint accepts for webhook_type, and the current docs group webhooks into the matching three categories: Custom, Address Activity, and NFT Activity.

Deprecated types
TypeStatus
MINED_TRANSACTIONDeprecated 2026-08-30 — no longer documented
DROPPED_TRANSACTIONDeprecated 2026-08-30 — no longer documented
NFT_METADATA_UPDATEDeprecated 2026-08-30 — no longer documented

As of 2026-08-30 these three strings no longer appear anywhere on Alchemy's webhook documentation — not on the overview or webhook-types pages, and not in the Notify API create-webhook type enum. Alchemy has published no deprecation notice or replacement mapping, so this is recorded as observed absence, not a vendor-announced removal, and no successor event is claimed. The example handlers still keep their branches so existing webhooks created before this date keep working; do not build new integrations on them.

For full event and payload reference, see references/overview.md and the Alchemy Webhooks docs.

Environment Variables

ALCHEMY_SIGNING_KEY=whsec_or_your_per_webhook_signing_key   # top-right of the webhook's detail page
# Only needed for programmatic webhook CRUD via the Notify API / alchemy-sdk:
ALCHEMY_AUTH_TOKEN=your_app_auth_token                      # distinct from the signing key

Local Development

# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 alchemy --path /webhooks/alchemy

Configure the resulting URL as the webhook target in the Alchemy Notify dashboard. Optionally allowlist Alchemy's egress IPs: 54.236.136.17 and 34.237.24.169.

  • Handler sequence — Verify first, parse second, handle idempotently third
  • Idempotency — Prevent duplicate processing (use the webhook id)
  • Error handling — Return codes, logging, dead letter queues
  • Retry logic — Alchemy retries with exponential backoff up to ~10 min (Free/PAYG) or ~1 hr (Enterprise)

# Alchemy Webhooks

## When to Use This Skill

- How do I receive Alchemy webhooks?
- How do I verify Alchemy webhook signatures (the `X-Alchemy-Signature` header)?
- How do I handle ADDRESS_ACTIVITY, NFT_ACTIVITY, or GRAPHQL events?
- Why is my Alchemy webhook signature verification failing?
- How do I set up Alchemy Notify webhooks for onchain activity?

## Verification (core)

Alchemy signs every webhook with **HMAC-SHA256 over the raw request body**, hex-encoded, in the
`X-Alchemy-Signature` header. There is **no** `sha256=` prefix and no timestamp — just the hex digest.
The key is the **per-webhook signing key** (copied from the top-right of that webhook's detail page in
the Notify dashboard, or fetched via the Notify API), **not** your app's Auth Token.

The `alchemy-sdk` npm package manages webhook CRUD but does **not** verify signatures — implement HMAC
yourself. Always compute the HMAC over the **raw** body; a re-serialized JSON body will not match.

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

function verifyAlchemySignature(rawBody, signature, signingKey) {
  if (!signature) return false;
  const digest = crypto
    .createHmac('sha256', signingKey)
    .update(rawBody, 'utf8')   // rawBody: exact bytes/string received, never re-stringified JSON
    .digest('hex');
  try {
    return crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(digest));
  } catch {
    return false; // length mismatch = invalid
  }
}
```

## Common Event Types

The webhook `type` field identifies the event. Alchemy webhooks are scoped per chain/network.

| Type | Triggered When |
|------|----------------|
| `ADDRESS_ACTIVITY` | ETH/ERC-20/ERC-721/ERC-1155 transfers involving tracked addresses |
| `NFT_ACTIVITY` | ERC-721/ERC-1155 transfers for tracked NFT contracts |
| `GRAPHQL` | A Custom Webhook GraphQL query matches new onchain data |

These three are the values the Notify API's
[create-webhook](https://www.alchemy.com/docs/data/webhooks/webhooks-api-endpoints/notify-api-endpoints/create-webhook)
endpoint accepts for `webhook_type`, and the current docs group webhooks into the matching three
categories: **Custom**, **Address Activity**, and **NFT Activity**.

### Deprecated types

| Type | Status |
|------|--------|
| `MINED_TRANSACTION` | Deprecated 2026-08-30 — no longer documented |
| `DROPPED_TRANSACTION` | Deprecated 2026-08-30 — no longer documented |
| `NFT_METADATA_UPDATE` | Deprecated 2026-08-30 — no longer documented |

As of 2026-08-30 these three strings no longer appear anywhere on Alchemy's webhook documentation —
not on the overview or webhook-types pages, and not in the Notify API `create-webhook` type enum.
Alchemy has published no deprecation notice or replacement mapping, so this is recorded as
**observed absence**, not a vendor-announced removal, and no successor event is claimed. The example
handlers still keep their branches so existing webhooks created before this date keep working; do not
build new integrations on them.

> **For full event and payload reference**, see [references/overview.md](references/overview.md) and the
> [Alchemy Webhooks docs](https://www.alchemy.com/docs/reference/webhooks-overview).

## Environment Variables

```bash
ALCHEMY_SIGNING_KEY=whsec_or_your_per_webhook_signing_key   # top-right of the webhook's detail page
# Only needed for programmatic webhook CRUD via the Notify API / alchemy-sdk:
ALCHEMY_AUTH_TOKEN=your_app_auth_token                      # distinct from the signing key
```

## Local Development

```bash
# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 alchemy --path /webhooks/alchemy
```

Configure the resulting URL as the webhook target in the Alchemy **Notify** dashboard. Optionally
allowlist Alchemy's egress IPs: `54.236.136.17` and `34.237.24.169`.
