Functions ¶

func ComputeSignature ¶

func ComputeSignature(t time.Time, payload []byte, secret string) []byte

ComputeSignature computes a webhook signature using Stripe's v1 signing method.

See https://stripe.com/docs/webhooks#signatures for more information.

func ConstructEvent ¶

func ConstructEvent(payload []byte, header string, secret string) (stripe.Event, error)

ConstructEvent initializes an Event object from a JSON webhook payload, validating the Stripe-Signature header using the specified signing secret. Returns an error if the body or Stripe-Signature header provided are unreadable, if the signature doesn't match, or if the timestamp for the signature is older than DefaultTolerance.
