Call a REST API with POST and request parameter

Hi! I want to call a REST API function with POST and a request parameter. In Swagger UI it works as follows: URL: ...actions/execute_query_json Parameters: request {take: 60, skip: 0, pageSize: 60, qid: "2", inline_Count:true, filters: "[]", sorts: "[]}   How can I pass this parameter(s) in Mendix? I tried it with an Export mapping, but I cannot select a parameter there, I guess I did something wrong. There is no parameter selectable. I just want to do the same thing like above.

Hello Raimund,

Yes, set content-type as application/json and try, i believe that should work.



In your microflow, before the REST call, you need to create a TaskQueryRequest object and set the attributes to the values you want to send in your request.  Once you do that you’ll be able to select that object as a parameter and you should be good to go.



Yes, it will look like this:


Now it works. HTTP Headers as follows




Hello Mike,

thank you for your quick Response.

Now it compiled, but I get an error. Do I have to set the Content type to application/json, or something like this somewhere?

Status: 415
Reason: Unsupported Media Type
Content: {"Message":"The request contains an entity body but no Content-Type header.
