Hi PhilipDAth, Really thanks for your answer they are very helpful. I don't want to use template because i want to have different settings for each network eg. vlans and lan adresses. I will give a try to the copyFromNetworkId and to the bulkimport, (really thanks to point me to this two features), but i worry it will be just a workaround. What i want to do is to implement different SDWAN settings for each network, or group of networks. In other word i want to change via API the configuration described as "Adding Performance and Policy Rules" at this link: https://documentation.meraki.com/Architectures_and_Best_Practices/Cisco_Meraki_Best_Practice_Design/Best_Practice_Design_-_MX_Security_and_SD-WAN/Meraki_SD-WAN
