POST
HTTPS request contains a JSON body with this format:
subscription.created
event payload).
webhook-timestamp
header) is included in every request for when the webhook attempt occurred. We recommend you reject webhooks with a timestamp that is more than five minutes away (past or future) from the current time.
Verifying signatures
Each webhook call includes three headers with additional information that are used for verification:
webhook-id
: the unique message identifier for the webhook message. This identifier is unique across all messages but will be the same when the same webhook is being resent (e.g. due to a previous failure).webhook-timestamp
: timestamp in seconds since epoch.webhook-signature
: the Base64 encoded list of signatures (space delimited)..
). In code, it will look something like:
body
is the raw body of the request. The signature is sensitive to any changes, so even a small change in the body will cause the signature to be completely different. This means that you should not change the body in any way before verifying.
Determining the expected signature
HMAC
with SHA-256
is used to sign webhooks.
So to calculate the expected signature, you should HMAC the signed_content
from above using the base64 portion of your signing secret (this is the part after the whsec_
prefix) as the key. For example, given the secret whsec_MfKQ9r8GKYqrTwjUPD8ILPZIo2LaLaSw
you will want to use MfKQ9r8GKYqrTwjUPD8ILPZIo2LaLaSw
.
Here is an example of how you can calculate the signature in Node.js:
webhook-signature
header.
This header is composed of a list of space-delimited signatures and their corresponding version identifiers. The signature list is most commonly of length one. Though there could be any number of signatures. For example:
