AWS Budget Lambda

A serverless Lambda function that notifies you of your month-to-date AWS spend using Notifox.

Prerequisites

• AWS CLI configured with appropriate permissions
• Terraform installed
• Notifox account and API credentials

Setup

1. Clone the Repository

git clone https://github.com/notifoxhq/aws-budget-lambda.git
cd aws-budget-lambda

2. Configure terraform.tfvars

This file will be used by terraform to set environment variables inside the Lambda function.

Get your Notifox API key and audience from the console at https://console.notifox.com.

Audience

Token

# terraform.tfvars
NOTIFOX_API_KEY="YOUR_API_KEY"
NOTIFOX_AUDIENCE="YOUR AUDIENCE"
SCHEDULE_EXPRESSION="0 20 * * ? *" # 8 PM UTC, every day

3. Deploy with Terraform

cd terraform
terraform init
terraform plan
terraform apply

4. Validate functionality

aws lambda invoke --function-name budget-lambda /dev/null

Troubleshooting

Common Issues

1. Permission Denied: Verify IAM role has required permissions
2. Notifox API Error: Check your API key and audience ID
3. Cost Data Missing: Ensure Cost Explorer is enabled in your AWS account
