With Postman, I can attach files in requests with form-data, I can also send nested JSON object in raw format, but how can I do both: sending nested-structure data with file
It didn't worked for me like that. For me only worked this way:
property[nested_field1]
property[nested_field2]
or arrays with objects:
array[0][nested_field1]
array[0][nested_field2]
array[1][nested_field1]
array[1][nested_field2]
Try setting values like below and choose file to upload.
