Invoke AWS Lambda Function Manually

This workflow demonstrates a basic yet powerful way to invoke an AWS Lambda function directly from n8n using a manual trigger. It consists of two nodes: a Manual Trigger node that starts the execution on demand, and an AWS Lambda node configured to call a specific function (e.g., hello-world-sample in ap-south-1 region). Users must set up AWS credentials in n8n for authentication.

The primary benefit is rapid testing and debugging of Lambda functions without relying on AWS CLI, console, or SDKs. It saves time for developers by embedding Lambda invocations into n8n's visual workflow builder, enabling easy integration with other services like notifications or data processing.

Use cases include serverless application testing, one-off computations, event simulation for Lambda triggers, and as a building block in larger automations (e.g., combining with webhooks or schedules). It's particularly useful in cloud development pipelines, CI/CD extensions, or when prototyping serverless architectures in IT and development environments.
