Create Custom Action

POST https://webhook.site/token/tokenId/actions

  • type (string) is the name of an Action Type.
  • order (int) specified which order the action is executed in.
  • parameters (object) can vary depending on the Action Type.
  • disabled (bool) if set to true, the action is skipped upon execution.
  • queue (bool) If set to true, the action is run asynchronously. More info here
  • delay (int, max 86400) If set (along with queue to true), Webhook.site waits the specified amount of seconds to run the action.
  • condition (uuid) If set to an ID of a Conditions action, the action will only run if the condition passes, and is otherwise skipped.

Example 1: Condition action
{
  "type": "condition",
  "order": 3,
  "disabled": false,
  "parameters": {
    "input": "$request.content$",
    "operator": "eq",
    "value": "",
    "action": "stop"

Example 2: WebhookScript action

now = to_date('now')

if (date_interval(now, expiry) < 0) {
    // Respond with 410 Gone
    respond('This content is no longer available.', 410)
}
"""

data = {
    "type": "script",
    "order": 1,
    "parameters": {
