Auth0 MailChimp Export

Auth0 Extensions

This extension allows Auth0 Customers to synchronize their Auth0 User base (those that have an email) with a MailChimp List. From within MailChimp, it is then possible to leverage all the benefits of marketing emails, automated messages and targeted campaigns.

More than 14 million people and businesses around the world use MailChimp. The MailChimp features and integrations allow you to send marketing emails, automated messages, and targeted campaigns. And the detailed reports help you keep improving over time.

For further information on MailChimp - please see This extension was inspired by this mailchimp forum post by Eugenio.


Review and address the Issues raised as part of code review.

Configure Webtask

If you haven't configured Webtask on your machine run this first:

npm i -g wt-cli
wt init

Requires at least node 4.2.2 - if you're running multiple version of node make sure to load the right version, e.g. "nvm use 4.2.2"

Running locally

To run the sample locally:

  1. Create an application (client) in Auth0
  2. Go to Auth0 API Management and create a Client Grant.
	"audience": "",
	"scope": ["read:users", "read:user_idp_tokens"]
  1. Run npm install
  2. Run
webpack && \
wt serve build/bundle.js --port 3000 --no-merge \
--secret AUTH0_DOMAIN="" \

Then, in separate terminal, just curl to execute.

Note: The client and client grant creating will be automatically when deploying though Auth0 Extensions.
