Config resource

You can provide configuration data for multiple Microvisor-empowered IoT devices using the Config resource. Configs are intended as a way to upload data such as API keys, PKI certificates, and other items to the Twilio cloud so they need not be baked into application code. Instead, the application code running on the device retrieves the Config when it needs the information.

Each Config is a key:value pair which your application code can access using Microvisor System Calls.

Keys are text identifiers of up to 100 characters in length. They must be unique for a given account.

Values must also be supplied as text, of up to 4096 characters in length. If you wish to make binary data available to your devices, you will need to encode it as text before creating the Config. For example, you might used base64 encoding. Your application must decode the value back to binary after acquiring it from the Twilio cloud.

Config resources are accessed at this endpoint:

https://microvisor.twilio.com/v1/Configs

Config resources are accessible from all devices associated with an account. For Configs that are made available to specific devices, please see Device Configs.

It is possible for anyone with account access to read back the value of any Config. If you have information which, once created, you would not like to be accessible to other account holders, use Secrets, which are, from the API perspective, write- and delete-only.
