Is there any method with documentation related to change the gateway config via API.

I have found some method to do this with APs and Switches but theire is no info about gateways.

APs --> https://developer.arubanetworks.com/aruba-central/reference/apiap_clisupdate_configuration_clis

I found an API used in a python library:

https://base_url//caasapi/v1/exec/cmd?serial_num=SERIAL

Is there any info of this API?

For example i want to execute via API:

"aaa user delete role ROLE"

I just posted syntax for the cli under the heading:

Do we have an API to delete files from the flash of the controller?  

But it looks something like this:

apiPath = '/caasapi/v1/exec/cmd'
apiMethod = 'POST'
apiParams = {
    'group_name': '{0}/{1}'.format('CENTRALGROUPNAME', '00:00:00:00:00:00') <- this is the central group and device mac
}
apiData = {
    'cli_cmds': ["hostname TESTROUTER", "!", "interface vlan 2", "ip address 10.0.0.1 255.255.255.128", "!"]} <- a list of the commands to execute
