Connect safely

URL source
Ecommerce product promotion
Turn Square products into recurring social and blog campaigns.
Turn an authorized public Square Online product or collection URL into continuously rotating campaigns. New products join the campaign, but they are not the only products Postly can publish.
Give your products more chances to be discovered. Build campaigns around new arrivals, seasonal offers, and evergreen favorites—then send interested shoppers to the original product page.
Keep facts current
Postly refreshes current public product facts from the source page before each publishing run.
Let AI shape the campaign
AI creates angles, hooks, captions, and article structure. Price, availability, ratings, shipping, and specifications must come from current source facts.
Product selection
A continuing rotation—not a one-time “new products” queue.
Choose the pool
Include collections, categories, tags, or specific products.
Set promotion weight
Pin important products or publish them more frequently.
Respect cooldowns
Avoid immediate repeats and give the catalog healthy coverage.
Loop continuously
When every eligible product has appeared, the weighted rotation continues.
What the Square source supports
- Square Online product pages
- Public collection pages
- Current page refresh
- Canonical links and source images
- Publish to supported social and blog destinations
- Choose products, collections, categories, tags, or a manual product set
- Repeat the catalog continuously instead of stopping after new products
- Pin priority products and give individual products a higher frequency
- Apply cooldowns and avoid immediate repeats when alternatives are eligible
- Refresh price and availability facts before publishing
- Use AI for campaign angles and destination-ready copy without inventing product facts
Prepare your Square campaign
- Paste an authorized public Square Online product or collection URL into the URL source workflow.
- Open the URL while signed out and confirm the product information is publicly readable.
- Review discovered facts, source imagery and the destination before scheduling; this workflow does not require a Square OAuth connection.
Example product campaign
A local maker uses the public Square Online page for a ceramic mug. The post describes the displayed material and size and links to that page. Private inventory details that are absent from the page are not added as if they had been verified.
If the source does not look right
If no usable product appears, check public access and whether the page exposes readable product information. A sign-in page, private dashboard or image-only announcement is not a reliable public product source.
