Challenges

Stock was updated manually on each marketplace, so sold-out items could still be ordered.

Each marketplace had a different data format and API rate limit.

Solutions

Stock lives in the central system. Every change is sent to the marketplaces through webhooks and a queue with automatic retries.

Every order uses a unique ID so it cannot be processed twice, and every event is logged for the operations team.
