Browser scripts are custom-defined JavaScript functions that are located inside of your browser window. You can use the following example to load an external script within the associated function.

this.load('https://scripturl';, callback);  //"callback" is a function() to execute after the script has been successfully loaded.

Add a Browser Script

Navigate to Developer Tools > Webhooks. On the webhook event, click Add Browser Script. A popup appears.
In the Name field, enter an internal name for the script.
In the Events section, select browser.order.completed.
In the Function text area, enter or paste your JavaScript code.
Click Add.

❗️
When using webhooks, you can execute browser scripts within the sandbox. However, if you are using a Popup Storefront, FastSpring will pass it to the container page using an API Callback function. To only pass the event to the container page, leave the function () empty.

Example

The example below fires browser.order.completed after FastSpring processes a transaction and sends the fulfillment.
