+===== Compliance XCH API =====
+At the moment we support four different API calls for NCCM and compliance:
+  * **nccm_run:** force an NCCM poll
+  * **nccm_submit:** Push a configuration to the NCCM
+  * **cmpl_run:** force a compliance check
+  * **cmpl_report:** retrieve a report for compliance on a policy, node group, shown per policy or per node
+==== Forcing an NCCM poll ====
+You can also force an NCCM poll through the exchange server. A sample exchange XML call looks like this:
+<code xml>
+<task>
+  <head
+    userid="--your login name--"
+    passwd="--your (encrypted) password--"
+    task_type="xml_request"
+    task_name="nccm_run"
+  />
+  <request
+    node_name="switch13"
+    fqdn="192.168.60.113"
+  />
+</task>
+</code>
+The parameters you can send are simple:
+  * **node_name:** the node's hostname. This can be either in the YCE or CMDB database
+  * **fqdn:** the node's fqdn. If no node_name is provided, we try to find the node based on its fqdn, which can be an ip or string.
+These nodes will be scheduled for an NCCM poll and they will be picked up on the nccmd daemon's next cycle (if load permits).
+==== Submit a manual NCCM configuration  ====
+The configurations are normally retrieved from the nodes (jobs, nccm poll). But sometimes it could be desired to upload a configuration directly into the NCCM. For example when a node configuration cannot be retrieved directly and a NCCM report or Compliance check is required anyway.
+The ''**nccm_submit**'' API call allows you to create an NCCM entry for a node as the 'latest' configuration. To submit a configuration for a node it must exist as either a CMDB node or as an YCE node.
+The configuration can be submitted with an optional attribute, ''nccm_polltime'', to insert a manual timestamp of the configuration instead of the current date and time. However, as with GIT and other 'diff' based storage engines, the NCCM cannot process submitted configurations out-of-order. The provided polling timestamps are mostly administrative and the configuration is still considered the 'latest' superseding the previous configuration. The option is useful mostly to submit a series of configurations taken at different historical moments. Their order is NOT verified or enforced although a transaction with an invalid or badly formatted nccm_polltime is rejected. The nccm_polltime must be formatted as "YYYY-MM-DD hh:mm:ss".
+As the configuration will be embedded in the XML-formatted API call, precautions must be taken to prevent conflicting XML characters in the configuration. Two options exists to achieve this.
+First the configuration can be **encoded** using HTML codes. The ''<'' and ''>'' will then be encoded as ''&lt;'' and ''&gt;'' respectively and some other characters will be treated likewise. The use of encoding must be explicitly indicated in the request by adding ''xml_decode="yes"'' in the "head" and ''<xml_decode>config</xml_decode>'' in the "request" part of the API call. This informs the API that the field "config" must be decoded.
+An example of this call using encoding:
+<code xml>
+<task>
+  <head
+    userid="username"
+    passwd="xxxxxxxxxxxxxx"
+    log_level="0"
+    task_type="xml_request"
+    task_name="nccm_submit"
+    xml_decode="yes" />
+  <request >
+    <node_name>asd--cr01001</node_name>
+    <nccm_polltime>2022-09-27 09:20:00</nccm_polltime>
+    <xml_decode>config</xml_decode>
+    <config>
+#
+# This configuration is automatically generated at 2022-06-09 16:59:00
+#
+hostname &lt;asd--cr01001&gt;
+snmp-server localhost
+#
+interface loopback
+  address 127.0.0.1 255.255.255.255
+#
+end
+    </config>
+  </request>
+</task>
+</code>
+The second option is to insert the configuration as **CDATA**. This encapsulates the configuration using the header ''<![CDATA['' and footer '']]>'', which informs the XML decoder to ignore any xml characters within this section. The use of CDATA does not require any variables in the API request.
+The same example using CDATA for the configuration:
+<code xml>
+<task>
+  <head
+    userid="username"
+    passwd="xxxxxxxxxxxxxx"
+    log_level="0"
+    task_type="xml_request"
+    task_name="nccm_submit" />
+  <request node_name="asd--cr01001">
+<config><![CDATA[
+#
+# This configuration is automatically generated at 2020-06-09 16:59:00
+#
+hostname <asd--cr01001>
+snmp-server localhost
+#
+interface loopback
+  address 127.0.01
+#
+end
+]]></config>
+  </request>
+</task>
+</code>
+The response to these calls:
+<code xml>
+<task>
+  <head> ... </head>
+  <request> ... </request>
+  <response
+    nccm_status="configuration unchanged, not added to nccm"
+    request_error="0"
+    request_status="completed">
+    <log>configuration has '14' lines</log>
+    <log>configuration unchanged, not added to nccm</log>
+    <nccm_data
+      action="upload"
+      job_descr="nccm upload"
+      node_domain="DOM013400"
+      node_fqdn="asd--cr01001.acme.com"
+      node_name="asd--cr01001"
+      node_vendor="HP_C5"
+      operator="username"
+      session_type="mgmt"
+      state="manual"
+      verbose="1"/>
+  </response>
+</task>
+</code>
+If a configuration was determined as unchanged, the response ''nccm_status'' will say as much. When a new entry is created in the NCCM, the message will read "created new nccm diff config: 65", where the number refers to the Nccm_id where it is stored.
+The response will also return the node details it used to create the NCCM entry like the fqdn, vendor and domain name.
+==== Forcing a Compliance check ====
+You can also force a Compliance check through the exchange server. A sample exchange XML call looks like this:
+<code xml>
+<task>
+  <head
+    userid="--your login name--"
+    passwd="--your (encrypted) password--"
+    task_type="xml_request"
+    task_name="cmpl_run"
+  />
+  <request
+    node_name="switch13"
+    fqdn="192.168.60.113"
+  />
+</task>
+</code>
+The parameters you can send are simple:
+  * **node_name:** the node's hostname. This can be either in the YCE or CMDB database
+  * **fqdn:** the node's fqdn. If no node_name is provided, we try to find the node based on its fqdn, which can be an ip or string.
+These nodes will be scheduled for compliance and they will be picked up on the nccmd daemon's next cycle (if load permits).
+==== Requesting reports ====
+You can request reports with the same search filters as you can in the reports form (for more information, refer to the [[menu:cmpl:reports|Reports]] section. A sample request looks like this:
+<code xml>
+<task response="">
+    <head
+        userid="--your login name--"
+	passwd="--your (encrypted) password--"
+	task_type="xml-request"
+	task_name="cmpl_report"
+    />
+    <request
+        type="rules"
+        report_template_id="1001"
+	hostname="ASD-CR01001"
+        policy_id="1005"
+        policy_name="Compliance Check 1"
+        rule_name="Compliance Check 2"
+        vendor_type="Cisco_IOS"
+        group_name="Cisco_IOS"
+	detail_level="3"
+        status="0"
+        severity="Critical"
+        report_summary="is not compliant"
+    />
+</task>
+</code>
+  * **type:** The report type. Mandatory
+     * 'policies': get results based on policies
+     * 'rules':    get results based on rules
+  * **report_template_id:** A report template id. Optional. When a value is provided it will load all filters in that template. Any other parameter values in this request will overwrite them if they exist.
+Either one of these following is mandatory, to prevent overloading the system
+  * **policy_id:** a policy's ID from the netYCE database
+  * **group_name:** a node group name
+Additional parameters to set as filters:
+  * **hostname:** A (part of a) hostname of a node. So both "switch1" and "swi" match "switch1". Optional.
+  * **policy_name:** A (part of a) policy name. Optional.
+  * **rule_name:** A (part of a) rule name. Optional.
+  * **vendor_type:** A vendor type. Optional.
+  * **detail_level:** The level of detail to show the report in:
+     * 0: Only only the basic policy or node information
+     * 1: Up to conditions - default
+     * 2: Up to condition details
+     * 3: Up to condition full details - this will return everything
+  * **status:** 1 ("compliant") or 0 ("not compliant"). Optional
+  * **severity:** The string version of the severity as set in the NCCM Lookup. Optional.
+  * **report_summary:** The report summary. Can be part of this string. Optional.
+A sample return is as follows:
+<code xml>
