JSM Assets API - how to add a field for referenced objects via api?

[Günter Halmans]

Hi,

I would like to add a field from type "Object" to an object type via the Asset REST API, but I always get an error message "The input is not valid...".
Here is my payload:
payload = {
"name": "GH Services",
"type": "1",
"description": "This is my first test column",
"typeValue": "123", ## id of the object type the field should be referenced to.
"additionalValue": "123"
}

The request itself works, e.g. in case I add a default text field. 

Any idea how I could make it?
Thanks in advance!

HI @Günter Halmans

What is the API you are making?

Can you also show the object and the object type attributes?

H Marc,

thanks for your reply!

Yes, I would like to add a new attribute to a given objecttype via API.
I'm using the following API "Post objecttypeattribute {objectTypeId}"

My request looks like this:

...and the attributes of objecttype with ID 141 like this:
