I used Meraki API's to develop Python automation script to fetch the data from CSV file with Organization name, Network name, Serial numbers of devices, administrator/user mail id's to be created and pass the values to Meraki dashboard in Json format to onboard new customer with Organization name, Network and Devices using serial number and assign Device naming convention (3 letters of Org.-3 letters of Network name-Device type-Floor-number). Create Vlans, IP addresses in the security product. This whole process will be done by executing the master script where all the modules are called.
