Key takeaways<\/h2>\n\n\n\n\n- Connecting a store makes products selectable inside the message builder<\/strong> rather than something you paste a link to.<\/li>\n\n\n
- Shopify is one of ten supported stores – WooCommerce, Etsy, BigCommerce, Magento, Squarespace, Wix, Gumroad, Printful and Spring are the others.<\/li>\n\n\n
- There are three separate product sources, and people confuse them: a manual URL, an uploaded spreadsheet, or a live connected store.<\/li>\n\n\n
- An uploaded catalogue needs a
link<\/code> column and tops out at 15 MB or 10,000 rows.<\/li>\n\n\n- Product links can be wrapped as tracking links, so clicks are counted per campaign.<\/li>\n\n\n
- Connecting the store does not change who you may message or when – that is still the messaging window.<\/li>\n\n<\/ul>\n\n<\/div>\n\n\n\n
What Connecting Actually Does<\/h2>\n\n\n\n
Less magic than it sounds, and more useful than it sounds.<\/p>\n\n\n\n
Products Become Pickable<\/h3>\n\n\n\n
Once a store is connected, its products appear inside the campaign builder as something you select, the same way you would pick an image. A step in a flow can then send a specific product, and on Instagram, Messenger and WhatsApp it renders as a native card in the conversation rather than as a URL the customer has to decide whether to trust.<\/p>\n\n\n\n
It is listed as an optional onboarding step, which is why so many accounts never do it. It takes a single OAuth approval.<\/p>\n\n\n\n
Ten Stores, Not Just Shopify<\/h3>\n\n\n\n
DMpro<\/a> connects Shopify, WooCommerce, Etsy, BigCommerce, Magento, Squarespace, Wix, Gumroad, Printful and Spring. If you sell on two of them, both can be connected and both appear as separate catalogues.<\/p>\n\n\n\nEach connection gets its own catalogue id<\/h4>\n\n\n\n
Internally a connected store’s catalogue is addressed as something like shopify_<connectionId><\/code>, which is how two stores stay separate in the same account.<\/p>\n\n\n\nStock is read live<\/h4>\n\n\n\n
You are picking from the store, not from a copy you uploaded in March.<\/p>\n\n\n\n
The Three Things Called a Catalogue<\/h2>\n\n\n\n
This is where setups go wrong, because all three look similar in the builder and behave completely differently.<\/p>\n\n\n\n
A Manual URL<\/h3>\n\n\n\n
You paste a destination on the campaign or on an individual step. No catalogue at all – it is one link. Correct for a landing page, a booking form or a single hero product, and the fastest thing to set up.<\/p>\n\n\n\n
A Custom Catalogue You Upload<\/h3>\n\n\n\n
A spreadsheet. The link<\/code> column is required; id<\/code>, title<\/code>, description<\/code> and image_link<\/code> are optional. The file can be up to 15 MB and 10,000 rows.<\/p>\n\n\n\nWorth using when the products are not in a supported store – a service list, a wholesale sheet, affiliate products – but remember it is a snapshot. It does not know you sold out.<\/p>\n\n\n\n
A Connected Store<\/h3>\n\n\n\n
The live version. Pick a product and the message carries what the store currently says about it. This is the one to use if your store is on the supported list, and the only one that will not quietly advertise something you no longer stock.<\/p>\n\n\n\n![\"Three](\"https:\/\/dmpro.brandid.app\/blog\/wp-content\/uploads\/2026\/10\/shopify-dm-automation-sources.jpg\")
