AWS Lambda Endpoint

AWS Lambda endpoints connect Gateway to serverless functions so approved tools and agents can invoke Lambda-backed operations.

Endpoint Kind

Use function as the endpoint kind when creating this endpoint through the API or dashboard.

What Gateway Uses This Endpoint For

Invoke serverless functions from governed workflows.
Centralize Lambda credential handling.
Provide a stable function endpoint for AI Orchestration tools.
Use custom endpoint URLs for local testing.

Basic Endpoint Shape

json

{
  "endpoint": "lambda-tools",
  "kind": "function",
  "config": {
    "read_conn": {
      "provider": "aws_lambda",
      "region": "us-east-1",
      "default_function_name": "process-request"
    }
  }
}

Create it with the endpoint API:

bash

curl -sS -X POST "$EDEN/endpoints" \
  -H "$AUTH_HEADER" \
  -H "Content-Type: application/json" \
  -d '{
  "endpoint": "lambda-tools",
  "kind": "function",
  "config": {
    "read_conn": {
      "provider": "aws_lambda",
      "region": "us-east-1",
      "default_function_name": "process-request"
    }
  }
}'

Configuration Fields

Field	Purpose
`region`	AWS region
`access_key_id`	Access key ID
`secret_access_key`	Secret access key
`session_token`	Optional session token
`default_function_name`	Optional default function
`endpoint_url`	Optional custom endpoint URL

Operating Notes

Functions can perform arbitrary side effects; treat invoke permissions as write authority.
Prefer dedicated functions for agent-callable operations.
Set timeout, retry, and idempotency expectations in the function contract.
