What it does

A practical reference Claude consults whenever you work with Amazon API Gateway.

  • API type selection: side-by-side table of HTTP API vs REST API vs WebSocket API with typical use cases.
  • Core concepts: resources, methods, integration types (Lambda Proxy, Lambda Custom, HTTP Proxy, AWS Service, Mock), and stages explained concisely.
  • Copy-paste CLI and SAM examples: aws apigatewayv2 create-api, the full REST API flow (resource → method → integration → deployment), a SAM template, and a Python Lambda handler.
  • CORS and JWT authorization: HTTP API --cors-configuration, the REST API OPTIONS + MOCK pattern, and Cognito-backed JWT authorizer creation.
  • Best practices & troubleshooting: performance/security/reliability checklists plus causes and debug commands for 403, 502, 504, and CORS failures.

Who it's for

  • Developers building serverless backends with Lambda + API Gateway
  • Teams that prefer CLI/SAM over clicking through the console
  • Anyone unsure whether HTTP API or REST API fits their case
  • Operators who need to narrow down post-deploy 403/502/504 errors fast

Example uses

  1. "Expose my Python Lambda at GET /items via an HTTP API using SAM" → Claude generates a template based on the skill's SAM snippet.
  2. "Enable CORS so https://example.com can call this API" → it walks through update-api --cors-configuration for HTTP APIs, or the OPTIONS + MOCK integration commands for REST APIs.
  3. "My deployed endpoint returns 502 Bad Gateway" → it checks the Lambda response shape (missing statusCode/body) first, then integration timeouts.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/api-gateway folder from the GitHub repo itsmostafa/aws-agent-skills into my ~/.claude/skills/api-gateway/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/itsmostafa/aws-agent-skills.git && mkdir -p ~/.claude/skills && cp -r aws-agent-skills/skills/api-gateway ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and move to a temporary folder, e.g. cd ~/Downloads.
  2. Clone the repository: git clone https://github.com/itsmostafa/aws-agent-skills.git
  3. Create the skills directory if needed: mkdir -p ~/.claude/skills
  4. Copy just this skill: cp -r aws-agent-skills/skills/api-gateway ~/.claude/skills/
  5. Verify with ls ~/.claude/skills/api-gateway — you should see SKILL.md.
  6. Restart Claude Code, then ask something like "create an HTTP API on API Gateway" to trigger the skill.
  7. To actually run the commands, install the AWS CLI and run aws configure for credentials and region. Replace the sample account ID (123456789012) and region with your own.
