=

require

(

)

;

function

hmacHeader

,

secret

)

{

if

(

||

!

secret

)

return

false

;

const

hash

=

crypto

.

createHmac

(

'sha256'

,

secret

)

.

update

(

rawBody

from

(

)

,

Buffer

)

;

}

catch

{

return

false

;

}

}

Express Webhook Handler

const

express

=

require

(

'express'

)

;

const

app

=

express

(

)

;

// CRITICAL: Use express.raw() - Shopify requires raw body for HMAC verification

.

post

,

express

.

raw

(

{

type

:

'application/json'

}

)

,

(

req

,

res

)

=>

{

const

hmac

=

req

.

headers

[

'x-shopify-hmac-sha256'

]

;

const

topic

=

req

.

headers

[

'x-shopify-topic'

]

;

const

shop

=

req

.

headers

[

'x-shopify-shop-domain'

]

;

// Verify signature

if

(

!

verifyShopifyWebhook

(

req

.

,

.

env

.

SHOPIFY_API_SECRET

)

)

{

console

.

error

(

'Shopify signature verification failed'

)

;

return

res

.

status

(

400

)

.

send

(

'Invalid signature'

)

;

}

// Parse payload after verification

const

payload

=

JSON

.

parse

(

req

.

body

.

toString

(

)

)

;

console

.

log

(

`

Received

${

topic

}

from

${

shop

}

`

)

;

// Handle by topic

switch

(

topic

)

{

case

'orders/create'

:

console

.

log

(

'New order:'

,

payload

.

id

)

;

break

;

case

'orders/paid'

:

console

.

log

(

'Order paid:'

,

payload

.

id

)

;

break

;

case

'products/create'

:

console

.

log

(

'New product:'

,

payload

.

id

)

;

break

;

case

'customers/create'

:

console

.

log

(

'New customer:'

,

payload

.

id

)

;

break

;

default

:

console

.

log

(

'Received:'

,

topic

)

;

}

res

.

status

(

200

)

.

send

(

'OK'

)

;

}

)

;

Important

Shopify requires webhook endpoints to respond within 5 seconds with a 200 OK status. Process webhooks asynchronously if your handler logic takes longer.

From Shopify Partner dashboard or app settings

Local Development

Install Hookdeck CLI for local webhook testing

brew install hookdeck/hookdeck/hookdeck

Start tunnel (no account needed)
