Adyen Webhooks
When to Use This Skill
- How do I receive Adyen webhooks (standard notifications)?
- How do I verify Adyen webhook HMAC signatures?
- How do I handle AUTHORISATION, CAPTURE, REFUND, or CHARGEBACK events?
- Why is my Adyen HMAC signature verification failing?
- What response body does Adyen expect from my webhook endpoint?
How Adyen Webhooks Work
Adyen sends standard notifications as an HTTP POST with a JSON body containing
a batch of notificationItems. Each item wraps a NotificationRequestItem:
{
"live": "false",
"notificationItems": [
{
"NotificationRequestItem": {
"eventCode": "AUTHORISATION",
"success": "true",
"pspReference": "7914073381342284",
"merchantAccountCode": "TestMerchant",
"merchantReference": "TestPayment-1407325143704",
"amount": { "value": 1130, "currency": "EUR" },
"additionalData": { "hmacSignature": "coqCmt/IZ4E3CzPvMY8zTjQVL5hYJUiBRg8UU+iCWo0=" }
}
}
]
}
Your endpoint must:
- Verify the HMAC signature on each item (
additionalData.hmacSignature). - Acknowledge with the literal body
[accepted]and HTTP 200 — otherwise Adyen retries.
Verification (core)
Adyen's HMAC is not computed over the raw request body. It is computed over a
:-delimited string of specific fields, in this exact order:
pspReference : originalReference : merchantAccountCode : merchantReference : amount.value : amount.currency : eventCode : success
Each field value is escaped (\ → \\, : → \:), empty fields become empty
strings, and the HMAC key from the Customer Area is a hex string that must be
hex-decoded before use. The result is HMAC-SHA256, base64-encoded, and compared
against additionalData.hmacSignature. Because the signature covers parsed fields,
you parse the JSON first, then verify each item.
The official @adyen/api-library SDK does all of this for you:
const { hmacValidator } = require('@adyen/api-library');
const validator = new hmacValidator();
// item = notificationItems[i].NotificationRequestItem (plain parsed object)
// ADYEN_HMAC_KEY = hex string from the Customer Area
const valid = validator.validateHMAC(item, process.env.ADYEN_HMAC_KEY);
// reads item.additionalData.hmacSignature and compares (timing-safe) internally
No Node SDK (e.g. Python/FastAPI)? Reproduce the algorithm manually:
import hmac, hashlib, base64, binascii
def calculate_hmac(item, hex_key):
a = item.get("amount") or {}
fields = [item.get("pspReference", ""), item.get("originalReference", ""),
item.get("merchantAccountCode", ""), item.get("merchantReference", ""),
a.get("value", ""), a.get("currency", ""),
item.get("eventCode", ""), item.get("success", "")]
data = ":".join(str(f).replace("\\", "\\\\").replace(":", "\\:") for f in fields)
key = binascii.unhexlify(hex_key) # hex → bytes
return base64.b64encode(hmac.new(key, data.encode("utf-8"), hashlib.sha256).digest()).decode()
# hmac.compare_digest(calculate_hmac(item, key), item["additionalData"]["hmacSignature"])

Common Event Types
eventCode | Triggered When |
|---|---|
AUTHORISATION | A payment was authorised (check success for the outcome) |
CAPTURE | Authorised funds were captured |
CAPTURE_FAILED | A capture attempt failed |
REFUND | A refund was processed |
REFUND_FAILED | A refund attempt failed |
CANCELLATION | An authorisation was cancelled |
CANCEL_OR_REFUND | A payment was cancelled or refunded |
CHARGEBACK | Funds were reversed by the shopper's bank |
NOTIFICATION_OF_CHARGEBACK | A chargeback dispute was opened |
REPORT_AVAILABLE | A generated report is ready to download |
Important: Always check the
successfield — anAUTHORISATIONwithsuccess: "false"means the payment was refused, not approved.
For the full event reference, see Adyen webhook types.

# Adyen Webhooks
## When to Use This Skill
- How do I receive Adyen webhooks (standard notifications)?
- How do I verify Adyen webhook HMAC signatures?
- How do I handle AUTHORISATION, CAPTURE, REFUND, or CHARGEBACK events?
- Why is my Adyen HMAC signature verification failing?
- What response body does Adyen expect from my webhook endpoint?
## How Adyen Webhooks Work
Adyen sends **standard notifications** as an HTTP POST with a JSON body containing
a batch of `notificationItems`. Each item wraps a `NotificationRequestItem`:
```json
{
"live": "false",
"notificationItems": [
{
"NotificationRequestItem": {
"eventCode": "AUTHORISATION",
"success": "true",
"pspReference": "7914073381342284",
"merchantAccountCode": "TestMerchant",
"merchantReference": "TestPayment-1407325143704",
"amount": { "value": 1130, "currency": "EUR" },
"additionalData": { "hmacSignature": "coqCmt/IZ4E3CzPvMY8zTjQVL5hYJUiBRg8UU+iCWo0=" }
}
}
]
}
```
Your endpoint must:
1. **Verify the HMAC signature on each item** (`additionalData.hmacSignature`).
2. **Acknowledge with the literal body `[accepted]`** and HTTP 200 — otherwise Adyen retries.
## Verification (core)
Adyen's HMAC is **not** computed over the raw request body. It is computed over a
`:`-delimited string of specific fields, in this exact order:
```
pspReference : originalReference : merchantAccountCode : merchantReference : amount.value : amount.currency : eventCode : success
```
Each field value is escaped (`\` → `\\`, `:` → `\:`), empty fields become empty
strings, and the HMAC key from the Customer Area is a **hex string that must be
hex-decoded** before use. The result is HMAC-SHA256, base64-encoded, and compared
against `additionalData.hmacSignature`. Because the signature covers parsed fields,
you parse the JSON first, then verify each item.
The official `@adyen/api-library` SDK does all of this for you:
```javascript
const { hmacValidator } = require('@adyen/api-library');
const validator = new hmacValidator();
// item = notificationItems[i].NotificationRequestItem (plain parsed object)
// ADYEN_HMAC_KEY = hex string from the Customer Area
const valid = validator.validateHMAC(item, process.env.ADYEN_HMAC_KEY);
// reads item.additionalData.hmacSignature and compares (timing-safe) internally
```
No Node SDK (e.g. Python/FastAPI)? Reproduce the algorithm manually:
```python
import hmac, hashlib, base64, binascii
def calculate_hmac(item, hex_key):
a = item.get("amount") or {}
fields = [item.get("pspReference", ""), item.get("originalReference", ""),
item.get("merchantAccountCode", ""), item.get("merchantReference", ""),
a.get("value", ""), a.get("currency", ""),
item.get("eventCode", ""), item.get("success", "")]
data = ":".join(str(f).replace("\\", "\\\\").replace(":", "\\:") for f in fields)
key = binascii.unhexlify(hex_key) # hex → bytes
return base64.b64encode(hmac.new(key, data.encode("utf-8"), hashlib.sha256).digest()).decode()
# hmac.compare_digest(calculate_hmac(item, key), item["additionalData"]["hmacSignature"])
