Particle product and device configuration file


maybe somebody can give me some advice. I have few Electron and actually I have a specific softwareon them with the hardware configuration (pins), external services access keys to publish data (thingspeak) and some variable that is specific for each device.

Now I am publishing a particle event and passing thingspeak key to a weebhook in device integration (one webhook for all the devices).

I would like to try the Particle product feature, mainly to keep all updated with the same software release but I don’t know how manage specific device configuration. Any advice?
