# asc_post_webhook

POST /v1/webhooks — register an HTTPS endpoint to receive App Store Connect event notifications for ONE app. ALL FIVE attributes are required: name, url (HTTPS), secret (HMAC-SHA256 signing key — store it on the receiving side first; it is write-only and never readable back), eventTypes (at least one of the 12), enabled. After creating, verify the endpoint with asc_post_webhook_ping. Useful pairing: BETA_FEEDBACK_*_CREATED events + the v0.16 asc_list_beta_feedback_* read tools.

  "jsonrpc": "2.0",

## Why asc_post_webhook is rated Medium

The tool creates a new webhook registration in App Store Connect, which is a reversible write operation. While webhooks can trigger external notifications and the secret material is sensitive, the operation itself is reversible (webhooks can be deleted/disabled).

From the tool's own definition: "Tool description states 'POST /v1/webhooks — register an HTTPS endpoint' and 'After creating, verify the endpoint', indicating creation of a new webhook resource. This is a write/create operation that modifies App Store Connect configuration."

## Use case

AI agents use asc_post_webhook to create or update resources in Appstoreconnect Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Appstoreconnect Mcp environment.
