Restlet Framework 2.2.0 and 2.3 M1 released! March 27, 2014

Posted by Swann Vichot in Restlet Releases, Uncategorized.

It’s been a year and a half since the 2.1.0 release of the Restlet Framework so we are proud to announce the release version 2.2.0!

In 2013 we were also very busy with the development of APISpark, our new cloud platform for web APIs based on the framework. Actually, we recently released APISpark 2.0 so feel free to try it out, there’s lots to explore!

A Field Guide to Web APIs by Kin Lane February 11, 2014

Posted by Swann Vichot in APISpark, General, Restlet General.
1 comment so far

Kin Lane, API Evanglist, has been in the technology space for over 20 years and wants to help the world understand the great value and potential that is growing in the web API market.

To do so, he teamed up with GigaOM Research and Restlet to write a comprehensive guide to web APIs. Follow Kin on Twitter: @kinlane

Kin Lane, API Evangelist

Following are the summary and a few extracts of the guide. Download the full electronic version here: A Field Guide to Web APIs.

  • Executive Summary
  • What are APIs used for?
  • Why are web APIs different?
  • History of web APIs
  • What technology goes into an API?
  • Deploying your web API
  • Established practices for managing APIs
  • Marketing and API evangelism
  • The Future of Web APIs
  • Cloud Trends
  • Key takeaways

“A new breed of web API has emerged, delivering a vision of a lightweight, low-cost approach to connect devices and allowing applications to exchange data efficiently.”

“The most popular approach to delivering web APIs is REpresentational State Transfer (REST). This approach to API design takes advantage of the same internet mechanisms used to view regular web pages, so it has the advantage of faster implementations and is easier for developers to understand and put to use.”

“A company with resources to deploy and maintain websites can easily research and deploy APIs using the growing variety of available API frameworks such as Restlet [...]“.

GigaOM Logo

“A handful of solutions such as APISpark [...] have emerged in the past year to provide API deployment as a service. They connect to existing or new data sources and then generate web APIs complete with a portal and management tools.”

“Cloud API deployment from common data sources is making API deployment accessible to the masses, enabling API deployment of numerous resources easier for developers while making API deployment something even a nondeveloper can understand.”

Restlet Logo

“PaaS, which is one of the fastest-growing aspects of web and mobile development, provides an API-driven suite of tools that provides essential services for developers in a pay-as-you-go approach. This is the next generation of business utilities designed for developer consumption.”

APISpark public beta launched December 23, 2013

Posted by Swann Vichot in APISpark, General, Restlet General.
1 comment so far

The APISpark team is happy to report the launch of its public beta. The access is no longer restricted and you can sign up today to create your first API on APISpark.com!

The launch was announced during the APIDays Conference (December 4th – 5th 2013) in Paris and feedback so far has been very encouraging. See this report on our participation to the event.


When signing up for APISpark, you will be able to follow tutorials to get you started and become familiar with the platform.

If you encounter any issue, you can let us know via the Help Desk so we can look into it and fix it. By doing so, you will be contributing to the successful development of APISpark and for that, we thank you.

New features and enhancements

Since our last release, we have made the following changes:

HTTPS endpoints for APISpark.net subdomains
We had previously announced HTTPS access to both the APISpark public web site and the console. Well, now you can also deploy your APIs safely as we have added HTTPS endpoints for all APISpark.net domains.

HTTPS endpoints

We also fixed SSL certificates to prevent unecessary browser warnings.

Quick export of Data Stores as Web APIs

Previously, creating a regular CRUD web API from an entity store required several steps including:

  • switching from the entity store to the dashboard
  • creating a new custom web API
  • importing the entity store from the API via the settings tab
  • launching the feature adding the resources from the store
  • switching to the API overview to see the new API contract

While this only takes five minutes to achieve, we realized that these steps are not very intuitive for new users. This is where the new API export feature really helps.

Quick export

Instead of five steps, you can now do all this in a single step! We have added an “Export custom API” action to the actions menu of entity stores (and also to file stores).

That action displays a special Web API creation wizard, right inside the store page. Once you fill out all the info and click on “Create”, you directly see the API overview of the new API.

Global ordering review

In this version, we also revamped the ordering of items displayed in the console, such as the properties of an entity and the list of resources of an API.

We now guarantee that their visual order will be maintained and will be logical as it can have some impact at runtime, for example on routing of API calls.


As you can see above, you can easily drag & drop a resource to change its order as well.

Misc changes

To ensure an efficient recovery plan, your structured data (store via the default entity stores) is now replicated 3 times in 2 regions (USA and Europe).

The next step for us it now to also replicate the web APIs and provide a cross-region deployment and availability of those APIs.

Finally, we also fixed about 18 bugs in this new release.

From all the Restlet team, we wish you Happy Holidays!

What an event!

First of all, let me just say that as a newbie to the API arena, I found this conference to be full of valuable information and extremely rich in content.

Api Days 2013 Paris.

There were many industry-leading speakers. Jérôme Louvel, CEO of Restlet, was a speaker for the first day of the event and had wonderful turnout for his speech “Web APIs, the New Language Frontier”. He also announced the public beta of APISpark, more details are coming in another blog post!

Api Days 2013 Paris.

If you missed it or are interested in reviewing the slides again, you can find them here:

Web APIs, the New Language Frontier from Restlet

The second and last day was a little less restless (pun intended – excuse me, as a non-tech person, this is probably the only one accessible to me!) Steve Sfartz, VP of Engineering at Restlet, gave his speech “How to Build your Web API”. There weren’t many developers in the room but we did get visits at our booth after the presentation and got valuable feedback and a very interesting use case to explore – thanks to Wenting Sun of Nanyang Technological University of Singapore.

Here are Steve and Wenting, using the APISpark platform on an iPad to build and study her API needs.

As a Gold Sponsor we were really happy with the way things were set up. There were some stimulating talks and positive energy throughout. Overall, a great success!

On a complete side note, breakfast was delicious and very français.

Thank you to Webshell and FaberNovel for organizing this great event.

Restlet gets funding to accelerate APISpark growth! November 13, 2013

Posted by Jerome Louvel in APISpark, Restlet General, Uncategorized.
1 comment so far

All the Restlet team is excited to share some great news today. We are announcing a large seed funding round, our company Board and new team members!

Open Roots

When I launched the Restlet open source project on TheServerSide in 2005 as a consultant, I didn’t know how far this could lead me, but I knew Restlet Framework was the first of its kind, true to the principles of the Web (the REST architecture style published in 2000).

It changed the way Java developers can build and consume web applications & sites, without forcing previous paradigms such as RPC and MVC into a web “pipe” or artificial separating web server (think Servlet) and web client (think Apache HTTP client) technologies.

From Noelios to Restlet

After many  iterations, we reached version 1.0 and transformed Noelios as a company in 2008 with my co-founder Thierry Boileau to offer professional services. This allowed us to fund the R&D effort on Restlet, dedicate time to the writing of ‘Restlet in Action’ book and refine our ROA/D methodology.

In 2010, our technology was getting mature with 6 consistent editions supported (Android, GWT, GAE, Java SE/EE, OSGi) and the web API and cloud computing market were warming up. We started thinking about the next 5 years, now that REST and web APIs were about to become mainstream.

What was our next challenge?

APISpark, a PaaS for Web APIs

We decided to build a product around our open core that would help developers create and use the hundreds of thousands of web APIs expected in the coming years.

Our new mission was to democratize REST and web APIs for the broader developers community, beyond our community of API experts and Java engineers. 

0111_apiSpark_Logo (wordpress)

APISpark was born from the idea that creating APIs should be as simple as creating blogs on WordPress.com: a couple of minutes, a simple browser and a fraction of the “Do It Yourself” cost. APISpark brings together the IDE, hosting and management aspects into an unified Platform as a Service (PaaS) for APIs.

We also renamed the company to Restlet and changed our business model to leverage the cloud economics. APISpark is a freemium service that any developer can use free to get started. See our pricing page for details.

Funding, Board and Team

In order to successfully pivot, we needed funding, help from experienced entrepreneurs and a stronger presence in Silicon Valley. Today, we are happy to announce that we have closed a $2M seed round from two European VCs (SIPAREX and CapDecisif Management) and a few individual investors. 

We are also delighted to welcome our Board members: Bertrand Diard, co-founder and VP Strategy of Talend, Reza Malekzadeh, VP Business of Cumulus Networks and Matthieu Hug, CEO of Fujitsu RunMyProcess, along with our investor representatives. See our Board page for details.

In addition, we are welcoming Stève Sfartz as a third co-founder and VP Engineering. His strong experience in online service operations and R&D management will help us grow and structure our engineering team. Olfa Zorgati is also joining our team as our new CFO, based in the Silicon Valley where I’m moving as well. See our Team page for details.

We have also posted our first job descriptions for open positions immediately available in our engineering team.


I’m excited to pursue Restlet adventure and would like to thank all contributors to the Restlet Framework, early testers of APISpark, company advisors, numerous partners and customers who helped us getting so far!

Jérôme Louvel
Restlet, CEO

APISpark integrates with existing data stores September 23, 2013

Posted by Jerome Louvel in APISpark, Restlet General, Uncategorized.
add a comment

Summer has been hot for the APISpark team. We improved the overall platform stability, fixed more than 50 issues, and added many new features. Today, we are happy to roll out a new release in production!

Re-expose your backend as web APIs

Today, mobile and HTML 5 applications are connected. These applications rely on a cloud backend to store user and shared data. Beside the lengthy Do It Yourself (DIY) approach, many developers prefer to rely on BaaS (Backend as a Service) providers such as Parse, StackMob and Firebase.

Several developers came to us asking for an easy and flexible way to re-expose data contained in their mobile backends. Moreover, these developers want to add business value to their data through custom, domain specific Web APIs. In other words, the built-in Web API provided for free by their traditional BaaS lacks flexibility and extensibility to suit their needs.

This is where APISpark’s new “Entity Store Wrappers” come into play, providing an easy way to expose one or multiple custom API on top of an existing BaaS. Click above to follow the APISpark tutorial for each wrapper.

Turn your Google Spreadsheets into APIs

In addition, we have worked on an integration with Google Spreadsheet. This brand new wrapper helps you expose structured data while keeping the ability to edit them using your traditional spreadsheet UI. We strongly believe that this wrapper will suit a large set of user needs and specifically Open Data use cases.

Expose your Database in the Cloud as APIs

To finish with, we also added a wrapper for any JDBC data sources, such as classic relational databases as explained in this tutorial. We have plans for additional entity wrappers, so please give us feedback on the integration models you would like to see work on.

Serve your existing files stored in AWS S3

Even though APISpark already comes with built-in file stores, internally backed by AWS S3, some users want to re-expose files stored in their own AWS S3 account. Thanks to the new File Store wrapper, APISpark supports this scenario as explained in this tutorial.

Our plan is to incrementally add new wrappers. Google Drive comes next on our list.

Many more enhancements!

In addition to these new wrappers, we have added many features based on your feed-back including:

  • GWT and Android client SDKs

  • Source code export for your web APIs (based on the open source Restlet Framework)

  • Support for GitHub login and more providers

  • Subscription management (plan selection, payment, billing)

  • Deployment region can now be selected (US-West or EU-West right now)

  • Enhanced dashboard filters, full-text capabilities, instant search

  • Terms of Use and Privacy Policy pages

Next steps

If you don’t have an APISpark account yet, we invite you to sign up for the beta. And if you can’t  wait to discover APISpark, walk through our first tutorial. If you want to know what is coming next, please check our updated public roadmap.

Thanks for all your feed-back. We can’t wait to seeing what you will build with APISpark!

New release of APISpark rolled out May 21, 2013

Posted by Jerome Louvel in APISpark, Restlet General.
add a comment

Today we are rolling out a third release of APISpark beta. The previous releases are described in blog posts #1 and #2. If you want an access to the beta, please share your interest in APISpark on Twitter (@apispark).

Also, you might want to read our latest “How much REST should your web API get?” blog post and the following discussion. Now, let’s continue with an overview of the changes released in production today!

Complex entities & representations

First, we added support for one of the most requested features: the ability to define and persist relationships between entities, including association, aggregation and composition.

We also added support for abstract entities and ensured that when automatically creating an API from an entity store via the import wizard, we expose complex entities via matching complex representations.


The Java and JavaScript client SDKs, the offline HTML and PDF documentations have also been updated to either use or describe complex representations. We will soon update the iOS client SDK as well.

API templates and contracts

APISpark can not only create a web API from scratch or from an imported entity store, it can also let you create a web API based on an API template. You can think of them as blog themes on WordPress.com that lets you create your own custom blog in just seconds.

New API templates can be created from scratch or from a complete API that has been already deployed and tested. See the “Extract template” action in the drop-down menu below.


Those templates then appear in your dashboard, with an icon surrounded by a thick orange border as illustrated below and can be reused to create new APIs.


Like complete web APIs, public templates can be promoted to APISpark Catalog. Instances can then be created in seconds, each having its own runtime, including dedicated HTTP endpoints, members or analytics data.

The API contract and implementation are not cloned and remain controlled by the origin template. A similar feature just for API contracts is also provided, only including the visible aspects of a web API including the list of resources, methods, representations and client SDKs.


API contracts have several benefits for API users including easy switching from one API provider to another, or calling multiple APIs supporting the same contract but exposing different data.

Enhanced API implementation

When you deploy an API with APISpark, we internally generate some source code that has the Restlet Framework as main dependency. This source code is then compiled and packaged before being hosted by APISpark.

Restlet Framework

We try to generate this code exactly like a Restlet Framework developer would have written it. This means that your web APIs created by APISpark can be as performant in production as those written by hand. APISpark doesn’t interpret web APIs at runtime, but execute them at full byte code speed.

In this release, we have enhanced the implementation layer of APIs with:

  • added support for multiple actions

  • implemented action types (call imported API / call imported store / return response)

  • streamlined generated mapping code for speedier execution time

  • other APIs can now be imported and invoked (composite APIs)

Upgraded to Cassandra 1.2

APISpark enable you to store structured data via local entity stores, and later expose them through one or multiple web APIs.

In order to support efficient multi-tenant hosting, we rely on Apache Cassandra. Even though this technology choice is not directly visible to APISpark developers, it is key for us to provide:

  • potentially unlimited entity store sizes, spreading across machine clusters

  • highly-available entity stores thanks to continuous replication across mutiple machines

  • live entity store schema modifications without having to restart the database

  • flexible replication schemes including multi-region deployments

Cassandra logo

In this new release of APISpark, we have refactored our persistence layer, upgrading to version 1.2 of Cassandra which brings new features: 

  • better multi-tenant performance for concurrent schema changes on entity stores

  • better scalability and fail-over behavior thanks to virtual nodes

  • speadier access thanks to new native driver

  • support for repeating properties thanks to the new collections feature in CQL3

Even though you don’t have a direct access to the low-level Cassandra database powering APISpark entity store, we want to let you know that we use the best-of-breed cloud database technology to power web APIs hosted on APISpark.

We are also working on entity store wrappers for data living outside APISpark platform to let you reexpose them through proper web APIs. Stay tuned for the next release of APISpark for more information about this feature.

Improved stability

In addition, we have started to roll-out intra-region fail-over support to ensure that your APIs hosted by APISpark are highly available in case of hardware failure. Currently APISpark runs from the Northen California data center of Amazon Web Services.


The next step is to roll-out the multi-region deployment with a second data center in Virginia so that in case a complete AWS region goes down (which is very rare but already occured in the past), your web API can still run out of the other region in a way that is almost transparent to your API users, beside the increased network latency.

Finally, we fixed several issues:

  • URI path variables are now declared when adding resources from imported entity stores

  • Adding multiple sources selection in the Mapping panel

  • Adding mapping support for path variables and query parameters when calling an API

  • Fixed API contract filtering on the dashboard

Getting started

If you want to see how creating, hosting and using web APIs looks like with APISpark, we recommend our first tutorial.
