CoBo companies, which consume APIs on behalf of their customers, face unique challenges such as the Noisy Neighbor problem, lack of visibility into API consumption, quota restrictions imposed by API providers, risk of API key exposure, and the need for auditing proof, particularly in regulated industries. These challenges can lead to service degradation, security risks, and compliance issues. To address these, CoBo companies should implement best practices like gaining comprehensive visibility, real-time tracking, threshold alerts, and optimal timing of API calls to manage consumption effectively. Secure storage of API keys, use of ephemeral keys for developer access, and centralized key management can mitigate security risks, while comprehensive tracking of API requests and maintaining audit readiness can ensure compliance and maintain customer trust. These strategies aim to optimize API usage, reduce risks, and uphold service quality and compliance for CoBo companies operating at scale.
