Create an email price watch
json
{
"canonical_product_id": "sony_wh1000xm5_black",
"target_price": 280,
"channel": "email",
"destination": "buyer@example.com"
}POST the body to /watchlists with Bearer authentication and a stable X-Price-Compare-Client-Id. Store the returned watch ID for later updates and deletion.
Update or pause a watch
PATCH can change the target price, destination, or status. Use paused when the rule may be resumed later; delete the watch when the customer no longer wants it retained.
Protect notification destinations
Treat email destinations as personal data. Restrict access, avoid logging full addresses, and remove watches according to the customer’s retention and deletion requirements.
