Example Keygen + FastSpring integration

The following web app is written in Node.js and shows how to integrate Keygen and FastSpring together using a Popup Storefront embed.

This example application may not be 100% production-ready, but it should get you 90% of the way there. You may need to add additional logging, error handling, validation, features, etc.

🚨 Don't want to host your own webhook server? Check out our Zapier integration.

Running the app locally

First up, configure a few environment variables:

# Your FastSpring API credentials (available under Integrations->API Credentials)
export FASTSPRING_API_USERNAME="YOUR_FASTSPRING_API_USERNAME"
export FASTSPRING_API_PASSWORD="YOUR_FASTSPRING_API_PASSWORD"

# Keygen product token (don't share this!)
export KEYGEN_PRODUCT_TOKEN="YOUR_KEYGEN_PRODUCT_TOKEN"

# Your Keygen account ID
export KEYGEN_ACCOUNT_ID="YOUR_KEYGEN_ACCOUNT_ID"

# The Keygen policy to use when creating licenses for new customers
# after they successfully purchase your product
export KEYGEN_POLICY_ID="YOUR_KEYGEN_POLICY_ID"

You can either run each line above within your terminal session before starting the app, or you can add the above contents to your ~/.bashrc file and then run source ~/.bashrc after saving the file.

Next, install dependencies with yarn:

yarn

Then start the app:

yarn start

Testing the integration locally

For local development, create an ngrok tunnel:

ngrok http 8080

Creating a FastSpring Popup Storefront

In order to utilize this integration, you'll need to create a FastSpring Popup Storefront. Then you'll need to edit the /views/index.ejs file and update the FastSpring embed code with your own embed code provided by FastSpring.

Be sure to add data-popup-closed="onFSPopupClosed" attribute to your embed script tag or else your integration will not work. You will also need to update the data-fsc-item-path-value attribute for the "Buy Now" button.

Testing the integration

Visit the following url: http://localhost:8080 and fill out the purchase form.
