#### Connect-Netbox

# Connect to Netbox
$nbUri   = 'https://netbox.domain.tld'
$nbToken = 'ApiKeyGoesHere'  # If "PSVault" module is installed, then something like this could be used:
                             # $nbToken = (Get-VaultCredential -Name Netbox).GetNetworkCredential().Password
Connect-Netbox -Uri $nbUri -Token $nbToken



#### Invoke-NetboxRequest

# Fetch all sites from NetBox
Invoke-NetboxRequest dcim/sites/ -Follow

# Fetch site with ID 1 from Netbox
Invoke-NetboxRequest -Uri dcim/sites/1/

# Create new tenant
Invoke-NetboxRequest -Uri tenancy/tenants/ -Method Post -Body @{name='Example Tenant'; slug='example-tenant'}



#### Find-NetboxObject


# Find all prefixes attaced to VLAN 3999.
Find-NetboxObject -Uri ipam/prefixes/ -Properties @{vlan = @{vid = 3999}}

# Find all prefixes attaced to VLAN 3999. "otherproperty" is ignored in search.
Find-NetboxObject -Uri ipam/prefixes/ -FindBy 'vlan.vid' -Properties @{vlan = @{vid = 3999}; otherproperty='foobar'}

# Find all VLANs belonging to VLAN group "test".
# Sometimes the NetBox API want queries "different". It's not "?group_slug=test" but "?group=test"
# If the "Findby" is omitted in this example, then NetBox will return all VLAN objects back, and the filtering will be done only on client side.
# Stuff like "Got 18 objects back from server and returned 2" can be seen in verbose output.
Find-NetboxObject ipam/vlans/ -Properties @{group=@{slug='test'}} -FindBy 'group=group.slug'



#### Invoke-NetboxPatch (you would often use Invoke-NetboxUpsert instead!)

# Patch tenant 3 with description.
# This is always sent to Netbox, even if description hasn't changes.
# The function doesn't know the previous state of the properties.
Invoke-NetboxPatch -Uri tenancy/tenants/3/ -Changes @{description = 'example'}

# Fetch VLAN object with id 1 and change description.
# If description is already correct, then a patch request isn't sent to Netbox.
# Old versions of Netbox didn't have an "url" property in objects. If that's the case, then this should be added:
# -Uri "ipam/vlans/$($v.id)/"
$v = Invoke-NetboxRequest ipam/vlans/1/
Invoke-NetboxPatch -Item $v -Changes @{description = 'example'}



#### Invoke-NetboxUpsert

# If prefix 10.0.0.0/30 already exist, then set description. If it doesn't exist, then create it.
Invoke-NetboxUpsert -Uri ipam/prefixes/ -FindBy 'prefix' -Properties @{
    prefix='10.0.0.0/30'
    description='example'
}

# Find all prefixes attached to VLAN 3999 and show which changes that should be made (as warning).
# Remove -NoUpdate to send patch requests to NetBox
Invoke-NetboxUpsert -Uri ipam/prefixes/ -FindBy 'vlan.vid' -Properties @{vlan=@{vid=3999}; description='example'} -Multi -NoUpdate
