Your catalogue already knows what launched. Your social accounts should not need telling separately.
Product launches, restocks and price drops are already events in your system. Announcing them is a manual job somebody does later, or forgets, and the networks that matter most are the ones with the fussiest media rules.
A restock fires a webhook in your system; that becomes a post. No one retypes anything.
Pinterest and Instagram carry the most commercial intent and the strictest media rules. Both are checked against their real pixel bounds and formats before anything is sent.
Queue the announcement for the exact local moment the drop opens, in the timezone you actually mean, through a clock change.
Clicks and saves come back alongside impressions, so the post that moved stock is identifiable rather than assumed.
Trigger on your own events, upload the product image once, post to every channel with one call.
curl -X POST https://api.postlake.dev/v1/posts \
-H "Authorization: Bearer $POSTLAKE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"text": "…", "accounts": ["acc_…"]}'Yes. Trigger on whatever event your system already emits and publish from it. Nothing needs re-entering by hand.
Pinterest and Instagram carry the strongest commercial intent, and both have strict media rules. Those rules are enforced up front, so a launch post does not fail at the moment it matters.
Yes, in a named timezone rather than UTC, so it fires at the local moment you meant even across a clock change.
