App Listing & Detail Page

LaunchMyStore renders an installed app’s in-admin detail page (/admin/apps/{handle}) and the marketplace listing (/marketplace/{handle}) from the same Apps row. This page is the field-by-field reference for everything you control on those two screens — what shows where, how to author it, and the publishing flow. This guide is for developers using the Developer dashboard at app.launchmystore.io/developer/apps to ship public apps to the marketplace.

Where each field shows up

Field	Marketplace listing	In-admin detail page
`name`	card title + hero	header title
`iconUrl`	card + hero icon	header icon
`tagline`	card subtitle	header subtitle
`description`	short summary	–
`categories`	category filter	–
`pricing`	price label	”Plan” row
`images` (screenshots)	gallery	–
`worksWith`	”Works with” pills	”Works with” pills
`installationGuide`	–	Getting started section
`tutorialVideoUrl`	embed	embed
`privacyPolicyUrl`, `supportEmail`, `documentationUrl`	footer links	footer links
`extensions.settings`	–	Settings card
`extensions.{storefrontBlocks, checkoutExtensions, …}`	–	“What this app adds”

Authoring fields at app creation

Open /developer/apps/create. The Listing Details section captures the three fields that change how the in-admin detail page reads:

string ≤100

The one-line subtitle under your app name. Both screens show this.

string[]

Newline-separated list of third-party services / platforms (e.g. Klaviyo, Google Shopping, Meta Shops). Renders as pills.

markdown

Setup instructions shown as the Getting started section on the in-admin detail page. See Writing a good installationGuide.

You can edit all of these later from /developer/apps/{appId} → Listing tab. Saving there issues a PATCH that the platform live-replays into both the marketplace listing and every merchant’s in-admin detail page — no re-publish needed.

The Install button only appears when the merchant has no installation row for this app. Clicking it opens /marketplace/{handle} where the standard OAuth → install flow runs.

Writing a good `installationGuide`

This is plain Markdown. The renderer is intentionally minimal — it supports:

Headings: #, ##, ###
Bold (**text**), italic (*text* or _text_), inline code (`text`)
Links: [label](https://…) — open in a new tab automatically
Ordered lists (1., 2., …) and unordered lists (-, *, +)
Paragraphs (separated by a blank line)

It does not support: HTML, images, tables, footnotes, or fenced code blocks. Keep instructions short and step-driven; merchants are usually on their first install when they read this.

Example — extension-only app

# Get Plinth running in 60 seconds

1. Open **Appearance → Themes** and click *Customize* on your live theme.
2. In the section picker, add the *Plinth bar* block above the **Header**.
3. Pick a style — *Trust badges*, *Free shipping*, or *Announcement*.
4. Set your **free-shipping threshold** under the **Settings** card on this page.

That is it — refresh your storefront and the bar appears across every page.

**Tip:** schedule a holiday-only bar by toggling *Show on homepage* off.

What happens if you leave it blank

The detail page auto-generates a “Getting started” section from your extension manifest:

Extension type	Auto-generated copy
Storefront blocks	”Open Appearance → Themes and add the `{block}` block.”
Snippets	”Use `{% raw %}{% render '{handle}' %}{% endraw %}` in your theme.”
Checkout / post-purchase extensions	”Renders automatically at checkout.”
Admin blocks	”Appears at in admin.”
Functions	”Runs as a `{type}` function.”
Settings	”Configure under Settings on this page.”

This is good enough to ship a v1, but writing your own guide is strongly recommended — auto-generated copy is generic and will not tell merchants the why (e.g. “set a threshold of $75 to recover 80% of abandoned carts”).

Field reference

These are the columns on the Apps table that the developer dashboard exposes. All are optional unless marked required.

Field	Type	Notes
`handle`	string	required, lowercase + hyphens, immutable after publish
`name`	string	required
`description`	text	shown on the marketplace card
`tagline`	string ≤100	shown under the app name
`developer`, `developerUrl`	string	populated by backend from auth
`appUrl`	URL	if set, the in-admin page renders an iframe instead of the extension-only detail page
`tutorialVideoUrl`	URL	optional embed
`type`	enum	`public`, `private`, `first-party`
`version`	semver	e.g. `1.0.0`
`categories`	string[]	one of: `selling-products`, `store-design`, `store-management`, `finding-products`, `orders-and-shipping`, `marketing-and-conversion`
`worksWith`	string[]	third-party services (Klaviyo, Meta Shops, etc.)
`installationGuide`	text	Markdown setup instructions
`pricing`	object	`{model, monthlyPrice, yearlyPrice, currency, trialDays, usage?}` — `usage: {unitName, unitAmount, cappedAmount, terms?}` declares a metered component (see Usage Billing)
`commissionRate`	number	DB column default `0.1` (10%). The marketplace seeder applies `0.06` (6%) to free apps only.
`images`	object[]	screenshots — `{url, alt}`
`iconUrl`	string	Hosted URL to a square icon. Supply a 256×256 PNG or SVG (renders down to ~52×52 in the marketplace card / admin header). Transparency supported; URL ≤ 2048 chars, no `data:` URIs. No upload endpoint — host it yourself and pass the URL.
`redirectUrls`	string[]	OAuth callbacks
`scopes`	string[]	requested OAuth scopes; validated against `ALL_SCOPES`
`extensions`	object	manifest of `storefrontBlocks`, `storefrontSnippets`, `checkoutExtensions`, `postPurchaseExtensions`, `adminExtensions`, `functions`, `settings`
`isPremium`	boolean	true for paid-only apps
`privacyPolicyUrl`, `supportEmail`, `documentationUrl`	URL/email	shown on the detail page

extensions.settings is what powers the in-admin Settings card. Each entry is {type, key, label, default, ...} (text, number, boolean, select). Settings render in disabled / preview mode if the merchant has not installed the app yet.

Two render modes for the in-admin page

/admin/apps/{handle} chooses one of two layouts based on whether appUrl is set:

AppEmbedFrame

Used when appUrl is set. Renders your hosted iframe with the App Bridge SDK loaded. You own the entire UI inside the frame.Use this for apps with a hosted dashboard, custom forms, or any UI beyond declarative extensions.

ExtensionOnlyDetailPage

Used when appUrl is null / empty. Platform-rendered header + Settings + Getting started + extensions list.This is the right choice for declarative apps (theme blocks, WASM functions, admin blocks) that don’t need a hosted dashboard.

If you want the platform-rendered detail page, leave appUrl empty.

Publishing flow

Create the app

At /developer/apps/create choose Save as Draft or Submit for Review. Drafts let you edit freely without affecting any merchant.

Add extensions and functions

At /developer/apps/{appId} use the tabs Extensions, Functions, Webhooks to register what your app contributes to the storefront, checkout, and admin.

Submit for review

Status moves draft → review → published. Review checks scopes, redirect URLs, and listing copy.

Merchants install

Once published, merchants see your app on /marketplace. Install creates the installation record and deploys your blocks / snippets to the merchant’s extensions/{domainSlug}/{handle}/ bundle on LaunchMyStore.

A clean uninstall removes the deployed bundle and refreshes the caches automatically — no leftover files pollute the merchant’s storefront.
