Adobe Inc. · Ecommerce & storefront platforms

Best for: Experienced PHP/Magento developers building deep, code-level extensions for enterprise and B2B merchants.

Overview

Magento Marketplace (now under Adobe Commerce) distributes PHP-based extensions and themes for Magento Open Source and Adobe Commerce Cloud. Extensions integrate deeply with Magento's module system rather than a hosted API surface, making it one of the more code-intensive ecosystems to build for.

How to build & ship

  1. 1Register as a developer in the Adobe Commerce Marketplace Developer Portal
  2. 2Build the extension as a Composer-packaged PHP module following Adobe Commerce coding standards
  3. 3Integrate via service contracts/APIs and add tests (e.g. MFTF) for quality and compatibility
  4. 4Package the extension and submit it through the Extension Quality Program (EQP)
  5. 5Pass automated code/malware/plagiarism scans plus manual engineer QA, then publish

Authentication & security

  • Primary auth: API key
  • Also supports: OAuth 2.0
  • Security review: Required
  • Marketplace technical review covers code quality, security, and packaging standards.
  • The EQP runs an automated scan (coding standards, malware, plagiarism) then a deep manual QA by a Commerce engineer covering security, performance, and core compatibility; multi-stage and often slow.
  • REST/GraphQL limits depend on hosting tier (on-prem vs. Adobe Commerce Cloud).
