Steps
Call the create_webhook(board_id, url, event, config) mutation with the webhooks:write scope; the target url is limited to 255 characters.
Choose an event type from the documented WebhookEventType values (e.g. create_item, change_column_value, change_status_column_value, item_archived, item_deleted, item_moved_to_specific_group, create_update, and others).
When monday calls your endpoint to verify it, echo back the challenge field from the POST body so the subscription activates.
List existing webhooks with the webhooks(board_id) query (webhooks:read scope) and remove one with delete_webhook(id).
Expect retries on delivery failure roughly once a minute for up to 30 minutes.
Known gotchas
You must echo the challenge value back exactly during verification or the webhook will not activate.
If your endpoint is down, monday retries about once a minute for 30 minutes, so build your endpoint to handle repeated/duplicate deliveries.
