Instalar NP Promo Pro

After purchase, the receipt page links to your zip and license key. Both are also emailed.

Back office → Modules → Module Manager → Upload a module → drop the zip. PrestaShop installs the schema (rule + application-ledger tables), registers the storefront and admin hooks, and adds the NP Promo Pro workspace to the back-office menu (under Modules on most installs).

The tabbed workspace (Campaigns / Flash Sales / Schedule / Audit) is where you create a rule: pick an effect type, set the targeting (category / product / brand / supplier / group / min cart total), and a schedule.

Before applying, the preview lists the exact products and old/new prices for catalogue edits and the CartRules planned for promotions. It issues a signed 15-minute review token bound to the exact payload; any edit requires a fresh preview. Export the CSV if you need a review record.

Apply only the reviewed payload. Cart effects compile to auto-applied CartRules and catalogue edits to SpecificPrice rows. A conflict, expired/changed token, changed catalogue snapshot or target above 2,000 products blocks the write. Then verify product, cart, checkout, order and invoice totals on staging.

Delete the rule (or let the schedule expire) and use the application ledger to target the CartRules and SpecificPrices created for that rule. Back up the database and verify the cleanup path on staging before uninstalling in production.
