Shopify App Merchant Finder — Competitor App User Leads API

Shopify App Merchant Finder

Shopify App Merchant Finder is a NexGenData tool on Apify that returns Shopify stores using a given app, with owner email, phone and socials from public Shopify store pages.

Find Shopify stores running a given app — displacement and integration prospects for your sales team. Charged per store identified.

Output is a prospect list for your sales team, assembled from public web and business sources. Use it in line with applicable outreach and privacy law.

✅ Pay only when we find it

This actor charges on success — you're billed per result delivered, not per attempt. No match, no charge.

⚙️ Sample inputs

This is the Store example input — the same input Apify's automated check runs — so it is proven to return rows on the current build. Paste it into the input form, or send it through the API, CLI or a schedule:

{
  "query": "email marketing",
  "maxApps": 40,
  "enrichDetail": true
}

🔧 Input reference

Field	Type	Default	What it does
query	string	"email marketing"	Free-text query to search apps.shopify.com (e.g. 'email marketing', 'shipping', 'SEO', 'reviews', 'upsell', 'dropshipping'). The query is matched against Shopify App Store categor…
appHandle	string	""	Fetch one specific app by its apps.shopify.com handle (e.g. 'klaviyo-email-marketing'). When set, the actor returns a single enriched item for that app and ignores query.
categorySlug	string	""	Pin discovery to a specific apps.shopify.com category slug (e.g. 'store-design-site-optimization-seo'). When set, overrides the query → category mapping.
maxApps	integer	40	Maximum number of apps to return. Each category page typically yields ~40 apps; the actor walks multiple categories until this limit is hit. Range: 1-200.
enrichDetail	boolean	true	When true, the actor fetches each app's detail page to extract JSON-LD ratings, the developer name, and the full description. Adds ~0.5-1s per app but produces much richer items.
notionConnector	string		Optional. Connect your Notion workspace and the discovered apps are also written as a Notion page in the same run — the Actor never sees your Notion credentials. Authorize a Notio…
notionParentId	string		Optional. The Notion page ID to create the page under. If blank, Notion creates a private page in your workspace.
supabaseConnector	string		Optional. Connect your own Supabase project and the results are also inserted into a table in the same run — the Actor never sees your Supabase credentials. Authorize a write-scop…
supabaseTable	string	"nexgendata_leads"	Target table in the public schema (created if missing, with id, a jsonb data column, and a scraped_at timestamp). Default: nexgendata_leads.
supabaseProjectId	string		Your Supabase project reference (e.g. abcdefghijklmnop). Required unless your connector URL is already project-scoped. Find it in your project URL: supabase.com/dashboard/project/…
deliveryDedup	boolean	true	When on (default), records already delivered in a previous run are not delivered again to the same destination — so scheduled runs only push new items. Turn off to deliver every r…

💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$0.02	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
Shopify store identified (store-discovered)	$0.05	Charged for each Shopify store discovered using the queried app (verified install)
Owner contact enriched (contact-enriched)	$0.15	Charged additionally when owner email or phone is successfully extracted from the store's contact pages

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.05 = $5.00 plus the start fee.
