]]> Give your customers a better experience — and your store a competitive edge.

The latest version of the FastSpring Store Builder Library (SBL), v1.0.5, is now available. This release delivers improvements in speed, security, stability, and features to our JavaScript library, ensuring your checkout stays modern, optimized, and competitive. If you’re still on an older version, now is the perfect time to upgrade.

What’s New and Why Upgrade

SBL v1.0.5 brings key improvements that enhance both your store’s performance and your customers’ checkout experience:

  • Faster Checkout: Optimized load times and responsiveness to boost conversions.
  • Enhanced Security: Patches for known vulnerabilities to protect buyer data.
  • New Features: Access functionality and enhancements exclusive to this version.
  • Improved Compatibility: Smooth performance across modern browsers and mobile devices.
  • Greater Stability: Bug fixes for a more reliable purchase flow.

Upgrading ensures your storefront stays secure and easy to use while reducing errors and providing the latest tools to improve the buyer experience.

Updating to the Latest Version

To integrate SBL v1.0.5 on your site:

  1. Go to FastSpring Dashboard → Checkouts → Popup Checkout → “Place on your website.”
  2. Copy the updated <script> snippet.
  3. Paste it into the <head> section of your site to load the latest version.

Risks of Not Updating

Continuing to run an outdated version of the SBL can negatively impact your store with:

  • Security holes that could expose buyer data or compromise transactions.
  • Slower performance that can lead to increased cart abandonment.
  • Missing features that limit your store’s potential.
  • Browser compatibility issues that break the checkout on newer devices.
  • Unpredictable bugs that hurt your customer experience and trust.

Upgrade Timeline

Most upgrades take 30-60 minutes, or up to 3 hours for complex setups. 

The process involves:

  • Reviewing your current implementation.
  • Updating your script reference.
  • Testing to confirm smooth functionality.

Frequently Asked Questions

How do I check my current version?

Inspect the <script> tag used to load the SBL on your site, or ask your FastSpring CSM.

Will updating affect my custom code or integrations?

The update is designed to be backward-compatible, but testing is recommended if you use custom or deprecated features.

Can I test before going live?

You can test the updated SBL in a production environment using a test product or a test purchase using test cards available on checkout. Reach out to Support for help with testing workflows if required.

Does FastSpring provide update support?

Contact our Support team if you need any assistance.

How often should I check for updates?

We recommend reviewing quarterly or whenever a new release is announced.

Where can I find the changelog?

See the full version history in the SBL documentation.

Are there any breaking changes we need to be aware of?

To clarify, the migration from your current legacy Store Builder Library (SBL) to v1.0.5 is straightforward, and there are no breaking changes in the core methods or API calls that you’re already using. All existing calls (e.g., fastspring.builder.*) remain fully supported.

Stay Current. Stay Competitive.

]]> At FastSpring, we’re always striving to provide our users with the best tools to enhance their FastSpring experience. One of the features that has been quietly revolutionizing the way our users interact with Store Builder Library (our JavaScript library), our APIs, and our webhooks is Recipe Docs. If you haven’t had a chance to explore it yet, let me show you why this feature is so powerful and why it’s quickly becoming a favorite among our users.

What Are Recipe Docs?

Recipe Docs are like your personal cookbook for integrating FastSpring into your business. Whether it be on your website or to backend systems, our Recipe Docs guide you through the steps to build out experiences that are tailored to your specific business use case. Each recipe cuts right to the heart of implementation without the need for any extra storylines like you’ll find in recipes across the web. The recipes include detailed and specific instructions and “ingredients” (e.g., sample code) that you can use to replicate the process in your own environment, making integration easy and quick.

Why Recipe Docs Are a Game-Changer

Not every user has a team of technical experts on staff ready to tackle complex implementations. That’s where our Recipe Docs come in. These step-by-step guides help you navigate the process of integrating FastSpring’s features without needing to rely on back-and-forth with our support team. Recipes empower you to take charge of your implementation by providing clear directions that demystify the process.

Some of the powerful capabilities you can unlock through Recipe Docs include:

  • Capture Order Data from FastSpring Checkout: Allow for real-time access to transaction details for further processing or integration with your other systems.
  • Preferred Payment Methods: Customize your checkout to offer the payment options that work best for your customers, boosting conversion rates.
  • Encrypt the Session Object: Ensure secure, complaint handling of user data to protect user privacy.

What’s Available Now?

Currently, FastSpring offers six detailed recipes, covering both API and SBL integration methods. Whether you’re a seasoned developer or just getting started, these recipes provide an excellent starting point for integrating key features into your existing workflow.

Some examples include:

  • Seamlessly adding new payment methods to improve the customer experience.
  • Authenticate accounts via account ID to ensure proper access to your products.
  • Using subscription management tools to improve customer retention.

The great part? You can easily assess whether FastSpring’s integration options align with your business goals before diving into a full implementation.

Built for Your Success

One of the standout benefits of Recipe Docs is the ability to self-evaluate FastSpring’s integration capabilities. By following these recipes, users can independently test and explore what’s possible with the FastSpring platform — saving time and avoiding potential roadblocks. 

Got Ideas for More Recipes?

The FastSpring Recipe Docs are continually evolving, and we’re always open to hearing what additional recipes you think would be helpful. If you have suggestions or feedback, we’d love to hear from you!

As part of an initiative to make our documentation more user friendly and insightful than ever, we at FastSpring have taken the initial steps to refine our documentation. 

This marks just the beginning of our journey, and we acknowledge that excellence is an ongoing pursuit. We are actively refining our developer documentation to ensure it is not just informative but comprehensive, equipping you with the tools you need to seamlessly resolve issues. Your feedback is invaluable as we work to deliver documentation that empowers you to self-serve with ease, speed, and confidence. 

Here are some of the key improvements so far:

1. Consolidation for Seamless Navigation

We have successfully moved product documentation into the existing developer documentation site. This consolidation ensures a more seamless navigation experience for you.  

2. Enhanced Search and Navigation

You’ll be pleased to know that we’ve revamped the search functionality, making it more effective in helping you find the specific documentation you need. When using search, you can filter between the product documentation and developer documentation.

Additionally, all docs now feature a scrolling table of contents, providing a user-friendly way to navigate through the content. 

3. An Improved Landing Page

We’ve introduced a new landing page design to make it easier for you to quickly find the information you need. The updated layout allows seamless access to both FastSpring App and Developer Documentation on a single page. Explore the improved visibility of documentation categories to navigate through topics that matter most to you. 

4. FastSpring API “Recipes”

We have initiated the development of “Recipes,” which serve as step-by-step guides within our API documentation. These recipes aim to provide practical walk-throughs to help you navigate and implement our features seamlessly. As we continue to expand this resource, we’ll be identifying Recipes that would be most beneficial to developers, including seeking your feedback on the types of Recipes that would be most beneficial to you.

Check out our first Recipes here.

5. Dark Mode/Light Mode for Developers

Recognizing the preferences of our developer community, we’ve introduced both dark mode and light mode options to enhance your viewing experience. Simply click on the sun/moon icon in the top right corner to switch between.

6. Documentation Feedback

You can now easily provide feedback using a simple thumbs up or thumbs down, along with comments to highlight what worked well and areas that could use improvement. Your comments will be actively reviewed and prioritized, ensuring that your input drives the necessary enhancements. We value your insights!

While we acknowledge that updating our developer documentation content  is a critical step, rest assured that we have gathered feedback from various sources and will be making these improvements in the upcoming months.

See the Ongoing Changes

Stay tuned for additional enhancements!
