howto create a mac address with python script

[IliasTsarouchas]

We tested with PUT and POST method with same json parameters. The request is successfull over the webinterface (https://netbox/api/schema/swagger-ui)

Thus the following script is intended to create a new mac address:

(Create Mac Address)

headers = {
"Authorization": f"Token {NETBOX_API_TOKEN}",
"accept": "application/json",
"Content-Type": "application/json"
}

params = {
"mac_address": mac_address,
"display": mac_address,
"assigned_object_type":"dcim.interface",
"assigned_object_id":assigned_object_id,
"description":mac_address,
"comments":mac_address,
"tags":[3],
}
try:
# Query physical interfaces
response_mac = requests.post(f"{NETBOX_API_URL}dcim/mac-addresses/", headers=headers, params=params, verify=False)
response_mac.raise_for_status() # Raise an exception for non-200 status codes
if response_mac.status_code == 201:
#response_mac.raise_for_status() # Raise an exception for non-200 status codes
macaddress = response_mac.json().get("results", [])
print(macaddress)
# Display results
if macaddress:
for result in macaddress:
print(f"MAC Address exits: {result['mac_address']}")
macID = result['id']
return macID
print(f"MAC Address: {mac_address} - Not found in NetBox")
return "NotFound"
except requests.exceptions.RequestException as e:
print(f"Error querying NetBox API: {e}")
# for ex in e:
# print(ex)
return 0

The result is:

Error querying NetBox API: 400 Client Error: Bad Request for url: https://ip.add.re.ss/api/dcim/mac-addresses/?mac_address=FF%3AFF%3AFF%3A99%3A99%3A11&display=FF%3AFF%3AFF%3A99%3A99%3A11&assigned_object_type=dcim.interface&assigned_object_id=123&description=FF%3AFF%3AFF%3A99%3A99%3A11&comments=FF%3AFF%3AFF%3A99%3A99%3A11&tags=3

We were asked to create a discussion post as this is probably not a bug. See: #20094

Can you please help us understand whats wrong? We are willing to provide any additional informations necessary. Thanks in advance for your kind support.

One apparent problem is that display field should not be set by the user, I think.

We also tried without setting display first. Same result.

I'd also recommend replacing params with json

[IliasTsarouchas]

The problem was in the parameters of the url for post request the name of the json data is "json", for get requests "params"

ex. response_mac = requests.post(f"{NETBOX_API_URL}dcim/mac-addresses/", headers=headers, json=json, verify=False)

Thanks for quick and valuable support!
