Is it recommended to use JMETER for API testing? How can I do this when I pass multiple request payloads via csv to add assertions?

I want to do API testing adding Assertions to the response. Can JMETER be used for this? The assertion would be added on an array of multiple ids. Is there a limit to the number of ids in the groovy script that need to be validated with assertion?
Also I used bunch of request payloads as csv input file for load test, how do I addd asserrtions for the multiple responses?
