+### How to
+
+1. create credentials for the Cisco Suport API [Cisco Support APIs](https://apiconsole.cisco.com/supportapis) via the [Cisco API Console](https://apiconsole.cisco.com/)
+1. add these credentials to the Cisco LifeCycle config file `~/etc/ciscoapi/ciscoapi.json`
+1. add a cronjob for the background plugins to fetch the data from the Cisco database
+1. let the HW/SW inventory pick up the data
+
+## CISCO Support APIs/Cisco API Console
+You need to have access to the [Cisco Support APIs](https://apiconsole.cisco.com/supportapis) via the [Cisco API Console](https://apiconsole.cisco.com/). There you need to create credentials for the plugin to work. These credentials need to have access to
+
+- **Bug API**
+- **EoX API**
+- **Product Information API**
+- **Serial Number to Information API**
+- **Software Suggestion API**
+- **PSIRT API**
+
+## Adjust the Cisco LifeCycle config file
+
+If you have your credentials you need to adjust the config file for the Lifecycle plugin.
+
+```
+~/etc/ciscoapi/ciscoapi.json
+{
+  "global": {
+    "use_system_proxies": false,
+    "wait_after_start": false,
+    "max_wait_time": 15,
+    "log_level": "debug",
+    "base_dir": "~/var/ciscoapi"
+  },
+  "eox": {
+    "refresh_known": 31,

+    "client_secret": "<your_client_secret>",

+    "client_fqdn": "",
+    "root_cert": true
+  },
+  "productinfo": {
+    "productseriesfile": "~/var/ciscoapi/productinfo"
+  }
+}
+```
+
+## Create a cronjob for the background tools
+
+Last step is to create a cron job for the plugin to fetch the data from the Cisco database. I tend to let it run every hour. 
+
+```
+~/etc$ cat ~/etc/cron.d/cisco_api_support 
+0 * * * * $OMD_ROOT/local/bin/ciscoapi/cisco-eox.py
+15 * * * * $OMD_ROOT/local/bin/ciscoapi/cisco-sn2info.py
+30 * * * * $OMD_ROOT/local/bin/ciscoapi/cisco-psirt.py
+45 * * * * $OMD_ROOT/local/bin/ciscoapi/cisco-bug.py
+```
+Don't forget to restart the cmk crond
+```
+omd restart crontab crontab
+```
+
+## Now wait for the background plugins to fetch the data, if the have, the cmk inventory plugins will pick them up in the next cycle.
