​
Configure settings for a project

To configure settings for a project, create a prefect.toml or .env file in the project directory and add the settings with the values you want to use. For example, to configure the PREFECT_API_URL setting to http://127.0.0.1:4200/api, create a .env file with the following content: 
PREFECT_API_URL=http://127.0.0.1:4200/api
To configure the PREFECT_API_URL setting to http://127.0.0.1:4200/api in a prefect.toml file, create a prefect.toml file with the following content: 
api.url = "http://127.0.0.1:4200/api"
Refer to the setting concept guide for more information on how to configure settings and the settings reference guide for more information on the available settings.

​
Configure temporary settings for a process

To configure temporary settings for a process, set an environment variable with the name matching the setting you want to configure. For example, to configure the PREFECT_API_URL setting to http://127.0.0.1:4200/api for a process, set the PREFECT_API_URL environment variable to http://127.0.0.1:4200/api. 
export PREFECT_API_URL=http://127.0.0.1:4200/api
You can use this to run a command with the temporary setting: 
PREFECT_LOGGING_LEVEL=DEBUG python my_script.py
