Log levels can be used to control log outputs. If logging is enabled at the specified log level, it also enables logging at all higher levels. The priority level of logs are in the following order: INFO (0) < WARNING (1) < ERROR (2) < NONE (3).



Logs that track the general events of the Calls SDK.


Logs that indicate potentially problematic situations.


Logs that represent the failure of the Calls SDK execution.

NONE (default)

Not used for writing log outputs.

Note: Calls SDKs for iOS and JavaScript share the same order for the priority level of logs.
