where can I find documentation about the file content

(I have example - but with no explanation)

Managed to run the API successfully using the following python code

    def updateReviewCoverage( self, reviewName, fileContent, reviewCoverageType = ReviewCoverageType.reviewer):

        url = f'{self.baseUrl}?cmd=uploadCoverage&type={reviewCoverageType.name}&name={reviewName}'

        req = HttpRequest('POST', url)

        req.addHeader('Authorization', f"Bearer {self.__GetAveksaToken()}")

        req.setBody(fileContent)

        req.setShouldVerify(False)

        req.makeRequest()

        responseBody = req.responseBody

        if("status=failure" in responseBody): # expecting "status=success\n"

            raise ValueError(responseBody)
