SSO Digital Solutions — Developer Reference

API Integration
Documentation

Technical implementation reference for all SSO Digital Solutions APIs. Covers authentication, endpoint schemas, request/response formats, and integration patterns for each tool in the SSO ecosystem.

⚠ API keys are issued exclusively to licensed SSO Digital Solutions clients upon execution of a signed sales order and custom service contract. Placeholder keys shown in this document (prefixed SSO_KEY_XXXX) are for structural reference only and will not authenticate. Contact enterprise@ssoentertainment.sbs to begin the contracting process.

Authentication ARDnDeX Neural Pipeline SSO Node Ingestion API Gateway Sync API Atmos Authoring Engine Lyrics Tooling API DDEX ERN Authoring Validation Engine Encoding & Localization Webhooks & Events

All SSO Digital Solutions API endpoints require bearer token authentication. Your API key is issued after execution of a signed sales order contract and is scoped to the specific tools included in your service plan.

Request Header

http

Authorization: Bearer SSO_KEY_XXXXXXXXXXXXXXXXXXXX
Content-Type: application/json
X-SSO-Client-ID: your_client_id_here
X-SSO-Version: 2026-01

Key Structure

Prefix: SSO_KEY_ — all production keys begin with this prefix
Scope: Each key is scoped to your contracted tool set. A key issued for ARDnDeX will not authenticate against the Atmos Engine endpoint unless that tool is in your contract.
Rotation: Keys expire on a 90-day cycle. Renewal notices are sent 14 days prior to expiry to the contract email on file.
Rate Limits: Default 1,000 requests/hour per key. Enterprise plans support burst limits up to 10,000 req/hr. Exceeding limits returns HTTP 429.

Obtaining Your Key

API keys are not self-service. To receive a key you must: (1) have a current signed sales order with SSO Digital Solutions, (2) have a negotiated custom quote covering the relevant tools, and (3) be provisioned by an SSO engineer. Contact enterprise@ssoentertainment.sbs to initiate the contracting process.

ARDnDeX (Automated Recursive Distribution and Network Data Exchange) is SSO's proprietary probabilistic validation and metadata inference engine. It uses Monte Carlo, Markov Chain, and Bayesian frameworks to perform predictive error analysis, ISRC/UPC conflict detection, and self-learning DDEX compliance verification.

The ARDnDeX API exposes three primary surfaces: Validate, Infer, and Audit.

Base URL

http

https://api.ssoentertainment.sbs/ardndex/v2

POST /validate — Probabilistic Metadata Validation

Submits a release metadata payload to the ARDnDeX stochastic validation pipeline. The engine runs Bayesian inference against global rights databases (BMI, ASCAP, IFPI) to verify consistency, detect ISRC conflicts, and flag DDEX schema violations before delivery.

POST /infer — Missing Metadata Inference

When submitting older catalog transfers, the ARDnDeX Predictive Clean Cataloging system can infer missing fields (historical ISRC dates, territory codes, rights organization registrations) using recursive distribution models trained on the SSO global catalog dataset.

GET /audit/{upc} — Catalog Audit Report

Pulls a full stochastic audit trail for a release by UPC. Returns all validation events, conflict scan history, rights routing status, and delivery integrity scores across DSPs. This is the primary tool for post-delivery reconciliation.

bash

curl https://api.ssoentertainment.sbs/ardndex/v2/audit/123456789012 \
  -H "Authorization: Bearer SSO_KEY_XXXXXXXXXXXXXXXXXXXX"

ARDnDeX Conflict Resolution — ISRC Live Transfer

If a "Live" ISRC is detected as still active at a previous distributor during the validation scan, ARDnDeX will flag a CONFLICT_LIVE_ISRC error and block delivery. You must issue a takedown request at the prior distributor after new assets are delivered to stores but before the final switch-over date. Use the /resolve-conflict endpoint to mark resolution after confirmation.

bash

curl -X POST https://api.ssoentertainment.sbs/ardndex/v2/resolve-conflict \
  -H "Authorization: Bearer SSO_KEY_XXXXXXXXXXXXXXXXXXXX" \
  -H "Content-Type: application/json" \

SSO Node is the infrastructure-layer ingestion engine. It accepts CSV and DDEX XML file uploads, parses them natively or via the ARDnDeX AI pipeline, and writes normalized release records to the distribution database. The Node API is primarily used by SSO engineers; label clients interact through the Onboarding Portal. Direct API access is available on Enterprise plans only.

Base URL

http

https://api.ssoentertainment.sbs/node/v1

POST /ingest — File Upload & Ingestion

Upload a catalog CSV, Delivery Log CSV, or DDEX ERN/MEAD XML file for ingestion. File type is auto-detected by filename and header structure. The Node processes the file asynchronously and returns an ingestion job ID for polling.

bash

curl -X POST https://api.ssoentertainment.sbs/node/v1/ingest \

The Gateway Sync API pushes normalized release records from SSO Node to the SSO Gateway distribution layer, which handles downstream delivery to 150–300+ DSPs globally. Only releases with a valid UPC are eligible for sync. The sync engine deduplicates by UPC, updating existing Gateway records only when status, title, or artist data has changed.

The Atmos Authoring Engine API accepts stereo or multitrack audio sources and returns a Dolby Atmos ADM BWF master file ready for delivery to Apple Music (Spatial Audio badge), TIDAL (Dolby Atmos), and Amazon Music HD. The engine uses intelligent spatial mapping and object placement — files cannot be "upmixed" from processed stereo; original multitrack stems are required for best results.

Audio Requirements

Source files must be WAV, minimum 24-bit / 48kHz (96kHz or 192kHz preferred for Hi-Res Lossless badge eligibility)
Apple Digital Masters badge requires files mastered by an Apple-certified mastering engineer — provide engineer name and email during submission
For Apple Music Hi-Res Lossless: provide at least 24-bit / 48kHz sources; 96kHz or 192kHz automatically triggers the Hi-Res badge
ADM BWF files are validated against SSO ADM Validator schema before delivery

The Lyrics Tooling API covers both the AI Lyrics Transcription Engine (speech-to-text TTML draft generation) and the Apple Music Sing Lyrics Tool (word-level timing, translation, romanization, and export). The API accepts audio file URLs and returns TTML documents compliant with Apple Music Sing delivery specifications.

ISRC-based bulk export available: POST /ttml/bulk-export with array of ISRCs
Beat-by-beat (word-level) sync is required for Apple Music Sing — line-level-only TTML will be rejected by Apple

SSO Digital Solutions APIs support outbound webhooks for asynchronous job completion and system events. Configure webhook endpoints in your SSO Node client dashboard (Enterprise plan). All webhook payloads are signed with HMAC-SHA256 using your webhook secret.

Signature Verification

javascript

const crypto = require('crypto');

function verifyWebhook(payload, signatureHeader, webhookSecret) {
  const expectedSig = crypto
    .createHmac('sha256', webhookSecret)
    .update(payload)
    .digest('hex');
  const receivedSig = signatureHeader.replace('sha256=', '');
  return crypto.timingSafeEqual(
    Buffer.from(expectedSig, 'hex'),
    Buffer.from(receivedSig, 'hex')
  );
}

Webhook Event Types

json

// ARDnDeX validation complete

Retry Policy

Webhooks are retried up to 5 times on non-2xx responses with exponential backoff (10s, 30s, 2m, 10m, 30m)
After 5 failures the event is marked dead and logged to your audit feed
Webhook endpoints must respond within 10 seconds or the delivery is marked as a timeout
