# RestFB, a dependency-free Java client for the Facebook Graph API

> restfb/restfb is a pure Java client for the Facebook Graph API that ships as a single JAR with no external dependencies, aimed at Java services that post content, read pages and manage Messenger and ads accounts. Maintenance is steady but the API surface it tracks keeps moving.

**restfb/restfb** — RestFB is a simple and flexible Facebook Graph API client written in Java.

## The case for a hand-written Graph API client

The Facebook Graph API is large and moves quickly. Endpoints cover posts, pages, accounts, ads, Messenger Platform conversations, Instagram accounts and Threads. A team that wants to publish a post or read a page from a Java backend can spend a week on request signing, paging through cursored responses and mapping error payloads before writing a line of business logic.

RestFB is a pure Java client for the Graph API with no external dependencies. That word pure is doing real work in the README: the library brings no third-party runtime jars alongside it, and the whole thing is distributed as a single JAR that you drop into your application. For teams that already run a container with a curated dependency set, or that have a policy against pulling a framework into a plain service, that is the main argument.

The project was created by Mark Allen and is maintained by Norbert Bartels with a wider group of contributors. The scope is deliberately narrow: it is a client for one API, not a social platform abstraction, and it carries topics for the Facebook, Messenger, ads and Instagram surfaces rather than a general integration framework.

## Building from source and the Java version split

The build is Maven, and the README is explicit about the version split. Builds require JDK 17 or newer, while the published RestFB artifacts still target Java 11. That combination is a deliberate choice to keep the shipped library consumable by older services while letting the build use a current toolchain.

Building is a single command, and the output lands in the target folder:

```bash
mvn package
```

Formatting is enforced rather than left to convention. Code formatting is checked during mvn verify, and the underlying check can also be run on its own:

```bash
mvn spotless:check
```

If a check fails, the configured Eclipse formatter can be applied instead:

```bash
mvn spotless:apply
```

For a contributor this matters more than it might appear. A build that reformats your diff means a pull request carries noise that has nothing to do with the change, and a formatter that runs inside mvn verify means the gate is part of the ordinary build rather than a separate CI job you can forget.

## Where to look when you need real usage examples

The README does not embed a code sample in the main usage section. Instead it points at three places, and knowing which one to open saves time.

The first is the documentation site, described as well-curated, with many code examples that are clearly commented and give a good overview of the functionality. The second is the integration tests in the repository under src/test/java/com/restfb/integration, which the README describes as exercising some interesting use cases and as a good way to get a feel for the different features. The third is a separate example project repository on GitHub, restfb-examples, containing a suite of tools triggered through Maven calls.

That example project also carries a specific piece of guidance worth knowing before you design a token flow. The fetching and publishing example includes a JavaFX code sample that shows how an embedded browser can be used to fetch a user access token. In other words, the library's own answer to the long-lived user token problem is a desktop browser flow, which points squarely at desktop tooling rather than a server-side token exchange.

For a service engineer, that means the integration tests are the better source of truth for server usage, since they run inside the same JVM as the library.

## Limitations and risks worth weighing before adopting

The first limitation is the dependency on someone else's platform. RestFB maps the Graph API, and the Graph API is versioned by Meta with breaking changes and deprecations. A client library can lag behind that. The README does not document a compatibility matrix against Graph API versions, and it does not document a rollback path for a breaking endpoint change, so you should treat the client version and the Graph version as two variables you track together rather than one.

The second is that the library is a client, not a platform service. It does not handle token storage, rate limit accounting, background refresh or audit trails. Those remain your code. Anyone expecting a managed Facebook integration will find a library instead.

The third is a support channel that changed shape. The README states plainly that Facebook suspended the RestFB page without providing a clear or understandable reason, and that support via Facebook is no longer possible. The remaining channels are GitHub Issues, Bluesky, LinkedIn, a Stack Overflow tag and a Google Group. That is a workable set for an open source project, but it is worth knowing that the most obvious social channel is gone.

A fourth, smaller point: the README mentions that RestFB uses other open source software, with details in the LICENSE.*.txt files, while RestFB itself is MIT licensed. Code copied into the project from elsewhere may carry different terms, so if you redistribute RestFB inside a product you should read those files rather than relying on the MIT summary.

## Release rhythm, versioning and the alternative

The repository is not archived and the last push was on 2026-08-15. The recent release list shows a monthly pattern: v2026.7.1 on 2026-06-09, v2026.8.0 and v2026.9.0 both on 2026-08-13. A calendar-based version scheme makes it easy to see how far behind a pinned dependency is, and it also means two different artefacts can share a date, which is worth checking when you compare versions.

The alternative is the official Graph API client maintained by Meta, which covers the same API but keeps a different scope and support model. There is also the option of skipping a client library entirely and calling the Graph endpoints over HTTP with the HTTP client already in your stack, which costs you signing, paging and response mapping but removes a dependency whose release cadence you do not control.

The difference in approach is that RestFB optimises for a small, predictable dependency footprint in a plain Java service. The official client optimises for coverage of Meta's own roadmap. A team that wants the former and is comfortable owning upgrade timing gets a clearer answer from RestFB.

## Conclusion

Adopt RestFB if your Java service talks to the Facebook Graph API and you want a client with no transitive dependencies and a single JAR to drop into a classpath. Skip it if you are starting a new integration today and can start with the official Graph API client or a maintained HTTP layer, because RestFB covers a long tail of Graph endpoints and carries its own compatibility burden. Verify first by building the project with mvn package on JDK 17, adding the resulting JAR, and checking that the endpoints you need are covered by the documentation and the integration tests.

## FAQ

### What is RestFB and what does it depend on?

RestFB is a pure Java client for the Facebook Graph API with no external dependencies. It was created by Mark Allen and is maintained by Norbert Bartels with a wider group of contributors.

### Which JDK do I need to build RestFB?

Builds require JDK 17 or newer. The published RestFB artifacts still target Java 11, so the build toolchain and the runtime target differ.

### How do I build the RestFB JAR?

Run mvn package and the jars are produced in the target folder. Code formatting is checked during mvn verify, and mvn spotless:apply applies the configured Eclipse formatter.

### Where can I find working RestFB usage examples?

The README points to the documentation site at restfb.com, the integration tests under src/test/java/com/restfb/integration in the repository, and a separate restfb-examples project on GitHub with tools triggered through Maven calls.

### What licence is RestFB released under?

RestFB itself is released under the MIT License. The README also notes that it uses other open source software and points to the LICENSE.*.txt files for those details.
