GET ListApiKeys

Lists the API keys for a given API. API keys are deleted automatically 60 days after they expire. However, they may still be included in the response until they have actually been deleted. You can safely call DeleteApiKey to manually delete a key before it's automatical

What can you build with AWS AppSync?

AWS AppSync is a Cloud API. Developers commonly use cloud APIs for:

provisioning and managing cloud infrastructure
automating deployments and container orchestration
monitoring uptime and performance metrics
managing storage buckets and databases
setting up auto-scaling and load balancing

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. AWS AppSync is free to use, making it a low-risk choice to experiment with.
