lambda-mailchimp

Create or update a Mailchimp subscription with this simple lambda function. Use it as a proxy for the Mailchimp API from your website/app without exposing your API key or running into CORS problems.

Usage

Setup

Get your username, API key, data center and list or audience id from your Mailchimp account.

• Create an API key here: https://admin.mailchimp.com/account/api/
• Your datacenter is the the first subdomain part, e.g. us18 when viewing your admin pages
• Find your unique list or audience id in your list or audience settings

Make a copy of the .env.sample

$ cp .env.sample .env

and fill in your details.

Upload

You can create a .zip file for uploading your lambda function to AWS with

$ npm run zip

API Gateway

After creating your new lambda function, uploading the zip file and saving your changes you add a new API Gateway trigger, leave all defaults as suggested by AWS and you're good to go.

You can send all parameters that should be proxied with a POST request to your new API endpoint, at least email_address is required. Read more about the optional parameters:

Return values

The lambda function transparently returns all reponse values from the Mailchimp API
