Functions

func ConstructEvent

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

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.

NOTE: Stripe will only send Webhook signing headers after you have retrieved your signing secret from the Stripe dashboard: https://dashboard.stripe.com/webhooks

func ConstructEventIgnoringTolerance

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

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 or if the signature doesn't match. Does not check the signature's timestamp.

NOTE: Stripe will only send Webhook signing headers after you have retrieved your signing secret from the Stripe dashboard: https://dashboard.stripe.com/webhooks

func ConstructEventWithTolerance

func ConstructEventWithTolerance(payload []byte, header string, secret string, tolerance time.Duration) (stripe.Event, error)

Initializes an Event object from a JSON webhook payload, validating the signature in the Stripe-Signature header using the specified signing secret and tolerance window. 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 the specified tolerance.
