I’m trying to send the vpn certificate expiry date to genieacs from Mikrotik’s. I have a script on the mikrotik that sends the data in what I believe is the correct date format and can curl the same data to the genieacs api but the data does not show up in genieacs. I’ve configured presets: curl -X GET [http://10.19.28.16:7557/presets](http://10.19.28.16:7557/presets) (truncated to just show expiredate) output: {“\_id”:“PersistCertExpiry”,“channel”:“RefreshData”,“weight”:1,“events”:{“2 PERIODIC”:true},“precondition”:“Device.DevicetInfo.Manufacturer = MikroTik”,“configurations”:[{“type”:“provision”,“name”:“refresh”,“args”:[[“PARAM”,“Device.Certificate.client.crt\_0.ExpireDate”]]}]} send the data manually: curl -X POST [http://10.19.28.16:7557/devices/E48D8C-RB2011UiAS-D5220EAE0632/tasks](http://10.19.28.16:7557/devices/E48D8C-RB2011UiAS-D5220EAE0632/tasks) -H “Content-Type: application/json” -d ‘{“name”: “setParameterValues”, “parameterValues”: [[“Device.Certificate.client.crt\_0.ExpireDate”, “2025-03-25T00:00:00Z”]]}’ but when i check mongoDB the data is missing: genieacs\> db.devices.findOne({ \_id: “E48D8C-RB2011UiAS-D5220EAE0632” }, { “Device.Certificate.client.crt\_0.ExpireDate”: 1 }) output blank: { \_id: ‘E48D8C-RB2011UiAS-D5220EAE0632’, Device: {} } appreciate anyone pointing me in the right direction. Thanks ---

Does `Device.Certificate.client.crt_0.ExpireDate` exist in the parameter list for the given CPE? ---

no. when I look at devices → parameter and do a refresh it doesn’t appear. i have it defined in the UI Admin under Presets, Provisions and even in the Config sections. example: | ui.device.2.parameters.15.label | Cert Expire | | --- | --- | | ui.device.2.parameters.15.parameter | Device.Certificate.client.crt\_0.ExpireDate | ---

Thats not how any of this works 😀. You can’t just “create” CPE parameters like that. Can you please distill down what you are trying to accomplish. Then I can hopefully help you find a path to achieve that goal. ---

😊 trying to collect vpn cert expiry date from all the infield Mikrotik Routers to be able to report and update them when required. hence why we’re trying to get it into genieacs Should it follow the vendor format like other parameters? example: Device.X\_MIKROTIK\_CertExpiry ---

**You** CANNOT create parameters under Device. Full stop. Those values **all** come from the CPE. You need to use a [vparam](https://docs.genieacs.com/en/latest/virtual-parameters.html). Here is the code for a non-parameter backed vparam. ```auto let value; log('My VParam', args); if ("value" in args[1]) { // Set declared value value = args[1].value; } else if ("value" in args[3]) { // No declared value, keep current value value = args[3].value; } else { // No current value, use default value = ['{}', 'xsd:string']; } return {writable: true, value: value}; ``` The SPV stays almost the same `curl -X POST http://10.19.28.16:7557/devices/E48D8C-RB2011UiAS-D5220EAE0632/tasks -H “Content-Type: application/json” -d ‘{“name”: “setParameterValues”, “parameterValues”: [[“VirtualParameters.CertExpireDate”, “2025-03-25T00:00:00Z”]]}’` ---

Thanks for the direction. I’m now able to push the certificate expiry time to Genieacs. ---

follow-up. my environment wasn’t saved ☹ I’ve recreated the virtual parameter and pushed a ‘expiry date’. I see the task being processed but again, not showing up in mongo db. what needs to ensure it’s persistent?
