API and Plugin Integration Overview
Set up your product, brand, licensing package, delivery, storefront, and managed checkout, with clear commercial responsibilities.
SoundSync
From account to a tested product
Some steps are optional for products that do not use plugin licensing or managed commerce.
-
Create the developer account
Confirm your business contact and read the terms and commercial policies.
-
Set the brand
Configure store name, logos, colors, support and reply-to details. For a custom root domain or subdomain, provide DNS access and follow verification; SoundSync provisions storefront SSL.
-
Create the product and price
Paid products, subscriptions, and bundles sold through SoundSync checkout must be priced at $9.99 or higher after discounts, before tax. Free access uses supported free-claim or external-redemption flows instead.
-
Configure delivery and licensing
Attach the appropriate files. For licensed plugins, select activation mode, device limits, and offline grace.
-
Choose the integration
Use HISEScript for the easier script path, HISE C++ for native authority with a source build, the complete JUCE package, or the documented HTTP API for a custom client.
-
Test customer access
Test activation, validation, deactivation, account/serial paths, offline expiry, and authorized downloads for your product.
-
Configure the storefront
Review product copy, media, brand, domain, and customer account access.
-
Test checkout
Confirm USD pricing, discounts, the $9.99 paid-price policy, tax location, enabled payment methods, and resulting customer access. Subscription checkout currently uses Stripe.
-
Publish and monitor
Review orders, customers, support, statements, usage, and the eligible payout cycle. Marketing requires the applicable consent.
Know the commercial model
SoundSync charges one 10% fee on product revenue after discounts and before tax. Payment processing is included for SoundSync-managed checkout. Marketplace-attributed sales use the same fee, not a second marketplace charge.
SoundSync Solutions is the Merchant of Record for purchases completed through SoundSync-managed checkout. SoundSync handles payment processing and applicable sales-tax/VAT calculation, collection, registration, filing, and remittance for those transactions.
The $10 monthly minimum is a minimum total of SoundSync charges, not a $10 subscription added to every bill. Sale fees, marketing-email charges, redemption overages, and other applicable SoundSync charges count toward it. If those charges total $7, the minimum adjustment is $3; if they total $12, no minimum adjustment is added. Sale fees already deducted from your proceeds are counted toward the minimum, not charged again on the statement. The shortfall is reconciled after the calendar month closes, not added separately to every partial-month statement.
Developer payouts are made twice monthly, on the 1st and 15th of each month, through Stripe Connect in USD. Payments have a minimum 14-day hold and enter the first scheduled payout after that hold completes, subject to unresolved adjustments and account restrictions. Older eligible balances remain eligible on the next run. The scheduled date is the payment-initiation date, not a guarantee of arrival in a bank or payment account.

Set a price, not a pay-what-you-want amount
SoundSync does not support pay-what-you-want pricing. Set the product or offer price yourself; customers cannot choose an arbitrary purchase amount. Paid products, subscriptions, and bundles must remain at $9.99 or higher after discounts, before tax. Supported free offers use the separate free-claim flow.
Pay with PayPal or Stripe, in USD
PayPal is accepted at SoundSync checkout for one-time purchases. Stripe supports card payments and available wallets. Subscription checkout currently uses Stripe, not PayPal.
SoundSync supports USD only currently. Products are priced and checkout charges are presented in US dollars; a payment provider's conversion into a buyer's account currency does not make checkout multi-currency.
Twice-monthly developer payouts through Stripe Connect
Developer payouts are made twice monthly, on the 1st and 15th, through Stripe Connect in USD. Each payment has a minimum 14-day hold; eligible unpaid funds enter the next scheduled run after that hold completes. These are payment-initiation dates, not guaranteed bank-arrival dates.
Stripe and PayPal checkout proceeds are transferred manually into a dedicated business account used only for developer, affiliate, and collaborator payouts, not business expenses. This is not an escrow or deposit-protection claim. Unresolved refunds, disputes, account restrictions, or destination checks can hold the affected balance.
