Multi-channel notifications — new opt-in digest feature for incremental-mode runs.
Enable via the new notifyOn input ("none" / "new_listings" / "price_drops" / "both";
default "none"). When enabled, the actor builds a structured digest at run end and writes
it to the persistent olx-cars-notifications Apify key-value store under two keys:
digest-latest (overwritten each run) and digest-<runId> (immutable per-run archive).
Optionally POST the same digest JSON to any HTTP endpoint via the new notifyWebhookUrl
input — supports Slack incoming webhooks, Discord webhooks, Make/n8n/Zapier, and any
generic HTTPS endpoint. Telegram direct POST requires a relay (see README).
notifyOn (enum string, default "none") — controls which events trigger a digest:
new_listings (new listings only), price_drops (price drops only), both
(new listings and price drops). Setting notifyOn != "none" without
incrementalMode: true causes the actor to fail immediately with a clear error message.
notifyMinPriceDropPct (integer 1–99, default 5) — minimum price reduction
percentage vs the prior-run snapshot price for a listing to appear in the digest's
priceDrops array. Values outside 1–99 are clamped with a WARNING.
notifyTopN (integer 1–200, default 20) — maximum number of items in each digest
section (newItems and priceDrops). New listings are ranked by most-recent firstSeenAt;
price drops are ranked by highest priceDropPct. Values outside 1–200 are clamped.
notifyWebhookUrl (string, default "") — optional HTTPS URL to POST the digest
JSON to at run end. POST failure is non-fatal (WARNING only; the digest is still saved to
the KV store). Keep the URL private — it is stored in run input history.
