REST API - Exporting a part to STEP works, but exporting to DXF does not

guillauem_d

Hello there ! 

I'm trying to export my sheet metal part using the REST API, exporting it to a STEP file works fine using the following method : 

• Initiate the exporting procedure using /api/v6/assemblies/d/{}/w/{}/e/{}/translations and inputing STEP as formatName
• Wait for the /api/v8/translations/{requestId}  requestState to be DONE
• Download the STEP using /api/v8/translations/{requestId}

The problem is that exporting to a DXF using the same method doesn't work, I know that it's probably because i'm not telling the code which face to export (just like I would manually), but I don't know how do input that.
Where should i plug the face ID ? Here is my working code for STEP files : 

payload = {

    "allowFaultyParts": True,

    "angularTolerance": 0.001,

    "formatName": "STEP",

    "storeInDocument": True,

}

response = requests.post(

    "https://cad.onshape.com/api/v6/assemblies/d/{}/w/{}/e/{}/translations".format(

        DID, WID, EID

    ),

    auth=(API_ACCESS, API_SECRET),

    headers={

        "Accept": "application/json;charset=UTF-8; qs=0.09",

        "Content-Type": "application/json",

    },

    json=payload

)

What changes should I make to make it work with DXF ?

Thank you in advance !
