I have a requirement of aggregating multiple APIs i.e. combining responses of two or more APIs. I was wondering if that can be achieved through WSO2 API Manager. TYK supports it in the form of 'virtual Endpoints'. How about WSO2 API Manager ? Any help appreciated.

  • I am actually looking for a way to do this too. Came across this. May not be exactly what you are looking at but can give you some idea. https://docs.wso2.com/display/IntegrationPatterns/Aggregator – user3731783 Jan 31 '17 at 19:47

Technically, this can be made byt the API Manager Gateway, since the gateway is an embedded version of the ESB gateway, so you can mediate all calls. See WSO2 EI documentation Be aware that in the API gateway there are some restriction, you have to use blocking calls .

However, the API Gateway should not be used to do "integration" of services if you want it to be highly scalable.

Could you elaborate on your specific needs ?

call API A then call API B with some A info and then produce a result ? Or more slogic like if API A yelds value X then call B else call C ?

If your need is API composition (multiple calls) you should use an integraiton layer. Either using code framework, like springBoot/Cloud or GraphQL server (superb tool to invoque multiple APIs) or WSO2 Integration solutions like Ballerina (micro compositions) or the WSO2 ESB (but it is from the monolithic world).

I hope it helps Cyril
