Hi there, I am trying to post an imageto another Mendix app by using REST. I succeeded to this with POSTMAN. See image: How do I do this by using a Call REST service action? What type of request should I use? Note that all the keys and values above are required. Thanks for your help!
I suggest you read the documentation on consuming REST services. For the file I think you have to encode it as a base64 string to add it to your request. There is a Java action for that in the Community Commons library.
