Unlike conventional API management platform providers, WSO2 API manager gives you the power to host your own API management server with almost unlimited configuration options and possible integrations.

The WSO2 API Manager provides you with the capability to have your own API management server with a plethora of features; Swagger documentation integration, the ability to define your own API products with different payment tiers and throttling, and even integration with various authentication methods. Best of all, it's all free. You can simply download the API Manager from their website and get it up and running within minutes, and it provides many out-of-the-box integrations.

It can be hard to understand how to get some of the configuration options for the WSO2 API Manager working, and even more difficult to configure it to suit very specific use-cases that don't fit its out-of-the-box functionality if you are not an expert in using it.

The open-source API gateway solution from WSO2 is a compact powerhouse that competes with the corporate giants like APIGEE without missing a beat. The Sequence driven API management helps in all aspects of the API life-cycle. The throttling is powerful and can be controlled via automated deployment mechanism. The deployment is simple and straight forward and has multiple options to control the flow of the API and auto recovery features in case of an endpoint suspension. It is a robust product with pretty intuitive development scene.

It is easy to install and learn faster if one had knowledge/worked on a similar integration tool

Documentation should be improved and provided with more examples

WSO2 APIM won me a lot of time instead of going back to the Backend Team to change or update the API, I do this modification only at the API Manager level, so I don't need a software developer to update and repeat the tests on the Backend again.

I have tried many API Management solutions as (MuleSoft ,Apigee and SoftwareAg ) WSO2 was the best among them, as it is characterized by a clear and large documentation, as well as the people you will find when inquiring on StackOverflow Collection .As he is the only open source API Management , one of its advantages is that even if the functionality is not implemented and released, it allows you to develop it and use it by implemeneted a new interfaces.

Until now WSO2 APIM doesn't suppot RAML specification .Artificial Intelligence capabilities implemented until now, need to be more improved.The documentation need to be implemented with real samples .

I've trained 100+ people in using the API Manager and it is my favorite of the 4 products from WSO2. IT works with all of the other products from WSO2. (IS as external Keymanager, EI as the mediation engine), BPS as the workflow engine) and Stream Processor (as the traffic manager and / or Analytics Server).

Where shall I start? It is one of the big 4 of WSO2 and a product suited for the frontend management of APIs. You could say it is like a guard that will let people or not, but then of course with API's (but also Soap Services and Websocket services). It is hard to focus on all features (my YENLO WSO2 API Training is 3 days and really is the tip of the iceberg). It downloads as a monolith and can be used as that but has 5 components : store, publisher, gateway, traffic manager and key manager. It uses a store concept where users (read: developers) can find, try,rate and subscribe to APIs. The definition of the API's is done in the Publisher where technical details as well as search and explanatory details are filled in. When you invoke an API it is done through the gateway. In essence it is a mini ESB / WSO2 EI since the synapse configurations are basically the same as the Enterprise Integrator. Both of them are SYnapse configs in XML, the difference of course is that the API manager is more extensive. What is great is the extensible lifecycle of the API Manager. This allows you to extend the lifecycle that an API goes through like created, published and deprecated. There are so many features that i did not describe. IT would have been a big review if i did.

Like with the ESB, the Synapse / AXIS2 components are 10+ years old. Those need to be replaced so there will probably be a migration process in the future. It does not mean the product doesn't function but the components are end of lif That is why we see the next version of the API manager (3.0.0) being developed but also the micro gateway now in version 3.0.1 (using ballerina as the language). Any product has its pros and cons, the API Manager is no different.
