# Securing Webhooks

# To ensure the authenticity of event requests, Mailgun signs them and posts the signature alongside the webhook's event-data.

# A signature takes the following form:
# Parameter 	Type 	Description
# timestamp 	int 	Number of seconds passed since January 1, 1970.
# token 	    string 	Randomly generated string with length of 50.
# signature 	string 	String with hexadecimal digits generated by an HMAC algorithm

<form method="POST">
<button type="submit" name="save">

</button>
<button type="submit" name="send-all">
  send all
</button>
</form>
