Hi @SushmaNaya , I believe this was asked before here but I dont think there is  a way to do it in one shot. you probably have to do it in custom script like executeScript processor where you can have part of the data stored as an attributes (depending how big the part is ) and then the other part is your flowfile content or have both stored as attributes (not recommended). Once you get the flowfile the execute script will get the content of the flowfile and the other aprt form the attribute construct your multi part body and send it that way. By the way if you are using Nifi 2.0 you probably can utilize python extensions to create your own custom processor using pure python when you can use different packages to help you with that. You can find example here: https://community.cloudera.com/t5/Support-Questions/Nifi-1-18-multipart-form-data-with-binary-part-and-json-part/m-p/386351#M246014 https://www.w3schools.com/python/ref_requests_post.asp Hope that helps ...

Hi, Another option is to use FreeFormTextRecrodSetWriter for that. The documentation is lacking about this unfortunately but you can find some examples like this if you google it. All you need is a ConvertRecord processor to get the desired result. here is an example :     - GenerateFlowFile is to simulate generating the csv input: - ConvertRecord: which takes the CSV input using CSVReader and Record Writer using the FreeFormTextRecordSetWriter:   - CSVReader Service Configuration: You can use default configuration.   -FreeFormTextRecordSetWriter: The Text used in the above Service to provide desired output: username = ${username} first name = ${"first name"} middle name = ${"middle name"} last name = ${"last name"}   Output: username = test_user first name = test_FN middle name = test_MN last name = test_LN username = test_user2 first name = test2_FN middle name = test2_MN last name = test2_LN   Hope that helps.               ...

Hi, Actually I went against the main  input since the second input (simplified version) is not valid json. Hopefully the following will work:     [ { "operation": "shift", "spec": { "description": "priceRuleName", "startDatetime": "startDate", "endDatetime": "enddate", "locations": { "0": { "location": "storeLocation" } }, "customAttributes": { "*": { "id": { "PR_PRICE_RULE_PROMO": { "@(2,valueBoolean)": "priceRulePromo" } } } }, "tiers": { "*": { "priceRuleAttributes": { "*": { "id": { "PR_BRANCH_NAME": { "@(2,values)": "paths.[&5].pathName" }, "PR_TARGET_SEGMENT": { "@(2,values)": "paths.[&5].customerCondition[#2].targetSegments" } } } }, "rewards": "paths[&1].calculatePrice", "conditions": { "*": { "conditionsMerch": { "*": { "item": { "": { "@(2,excludeInd)": { //group categories under yes\no include ind "0": { "@(4,categoryId)": "paths[&9].catalogCondition.category.yes.categoryList[]" }, "1": { "@(4,categoryId)": "paths[&9].catalogCondition.category.no.categoryList[]" } } }, //there is a valye in item -> products "*": { "@(2,excludeInd)": { //group products under yes\no include ind "0": { "@(4,item)": "paths[&9].catalogCondition.products.yes.productList[]" }, "1": { "@(4,item)": "paths[&9].catalogCondition.products.no.productList[]" } } } } } } } } } } } } , { "operation": "shift", "spec": { "*": "&", "paths": { "*": { "*": "&2[&1].&", "catalogCondition": { "*": { //products or category "*": { //bucket each yes\no group into its own array element "*": "&5[&4].&3.&2[#2].&", "$": "&5[&4].&3.&2[#2].include" } } } } } } } /**/ ] Also something to consider is using JSLT. JSTL is another json transformation language similar to xquery in syntax ( check reference here) . There is jslt processor in nifi for that. In my openion jslt works better in these situation specially when you trying to query data from very nested structure using some complex logic to match on certain values . You probably have to write less lines in jslt and the logic is easier to follow than jolt (of course if you have get familiar with jslt syntax and how it works first to make sense of it) Here is how this transformation looks using jslt: import "http://jslt.schibsted.com/2018/experimental" as exp let priceRulePromoArray = [for (.customAttributes) .valueBoolean if(.id=="PR_PRICE_RULE_PROMO")] let mainInfo = { "priceRuleName":.description, "startDate":.startDatetime, "enddate":.endDatetime, "storeLocation":.locations[0].location, "priceRulePromo":$priceRulePromoArray[0] } let paths= [for(.tiers) { "pathname":flatten([for(.priceRuleAttributes) .values if(.id=="PR_BRANCH_NAME")]), "customerCondition":[for(.priceRuleAttributes).values if(.id=="PR_TARGET_SEGMENT")], "calculatePrice": .rewards, "catalogCondition":[for(.conditions) let groupProductByInd = exp:group-by([for (.conditionsMerch) . if(.item!="")] ,.excludeInd, .item) let groupCategoryByInd = exp:group-by([for (.conditionsMerch) . if(.categoryId!="")] ,.excludeInd , .categoryId) let products = [for ($groupProductByInd ) { "include": if(.key==0) "yes" else "no", "productList":.values } ] let category = [for ($groupCategoryByInd ) { "include": if(.key==0) "yes" else "no", "categoryList":.values } ] if(any($products)) {"products":$products} else {} + if(any($category )) {"category":$category} else {} ] } ] {"paths":$paths}+$mainInfo   ...
