Technical Evaluation Framework: Vetting Amazon API Integration Developers

Integrating with Amazon APIs (SP-API, Advertising API, AWS SDK) requires navigating strict rate limits, data schemas, and marketplace operational requirements.

1. Amazon API Architecture & Integration

• ▸
  Selling Partner API (SP-API) Mastery: Handling OAuth2 authorization, AWS STS token exchange, RDT (Restricted Data Tokens), and encrypted PII.
• ▸
  Rate-Limiting & Asynchronous Feeds: Architecting resilient token-bucket rate limiters, asynchronous report generation, and Feed API bulk ingestion.
• ▸
  Amazon Advertising API & Webhooks: Real-time bid optimization, Sponsored Products data pipelines, and EventBridge notification consumers.

2. Buyer Diligence & Vetting Criteria

1. ▸
   Amazon Data Protection Compliance: Implementing required data governance (encryption at rest/in transit, key rotation) to satisfy Amazon's strict developer policy audits.
2. ▸
   Scalable Data Ingestion: Handling millions of transaction records, inventory feeds, and settlement reports via cloud queues (SQS, SNS, Lambda).
3. ▸
   Error Handling & Retry Resilience: Exponential backoff algorithms and dead-letter queues to gracefully handle throttling (HTTP 429) and transient API errors.

3. Red Flags to Watch For

• ▸
  Polling Instead of Event Webhooks: Continuously polling endpoints rather than subscribing to Amazon SQS/EventBridge webhooks, leading to constant rate-limit throttling.
• ▸
  Inadequate PII Protection: Storing customer shipping information unencrypted, risking immediate Amazon developer license revocation.
• ▸
  Ignoring API Deprecation Cycles: Building on deprecated MWS endpoints instead of modern Selling Partner APIs.
