Webhook

Name: SimpleFunctions
Author: SimpleFunctions

A webhook is an HTTP callback that sends real-time notifications to your application when specific events occur — such as price alerts, strategy triggers, or thesis confidence changes.

CLI:sf thesis update --webhook

Webhooks for Prediction Market Automation

Webhooks let you receive instant notifications when something important happens, without constantly polling for updates.

What Triggers Webhooks

SimpleFunctions can send webhooks for:

Price alerts: A contract crosses a threshold you set
Edge alerts: New edge detected above your minimum
Strategy triggers: A strategy entry or exit condition is met
Evaluation updates: Thesis confidence changes significantly
Heartbeat summaries: Periodic summaries of monitoring activity

Webhook Payload

Each webhook sends a JSON payload with structured data:

{
  "type": "strategy_trigger",
  "thesisId": "...",
  "strategy": "S-001",
  "action": "entry",
  "market": "KXRECSSNBER-26",
  "currentPrice": 0.29,
  "thesisImplied": 0.42,
  "edge": 0.13,
  "timestamp": "2026-03-19T14:30:00Z"
}

Common Integrations

Slack/Discord: Forward webhook payloads to a channel for team visibility
Telegram: Get mobile notifications via a Telegram bot
Custom bots: Trigger automated trading workflows
Zapier/Make: Connect to any service without code

Setting Up Webhooks

You can set a webhook URL per-thesis:

sf thesis update --webhook "https://your-app.com/webhook/sf"

The agent also supports webhooks as a signal input — external services can push signals to your thesis via webhook, which the evaluation cycle processes like any other signal.

Example

# Set up a webhook for your thesis
sf thesis update recession-2026 --webhook "https://hooks.slack.com/services/..."

# When a strategy triggers, Slack receives:
{
  "type": "strategy_trigger",
  "thesis": "US Recession by 2026",
  "action": "BUY",
  "market": "KXRECSSNBER-26",
  "quantity": 50,
  "price": "$0.29",
  "edge": "+13pt",
  "reason": "Edge exceeds threshold, price below entry condition"
}

Related Terms

Evaluation Cycle

An evaluation cycle is the automated process by which the agent reviews new signals, updates causal tree probabilities, recalculates edge, and determines whether any strategy conditions are met.

Heartbeat

The heartbeat is the automated monitoring engine that periodically scans for new information, runs evaluation cycles, and triggers strategy actions. It keeps your thesis alive and responsive 24/7.

Signal

A signal is any piece of new information that could affect a thesis — a news article, a price movement, a data release, a user note, or an external webhook event. The agent evaluates signals against the causal tree.

API Key

An API key is a secret token that authenticates your requests to SimpleFunctions and to prediction market venues (Kalshi, Polymarket). Each key has permissions and rate limits.
