You will need to set
.env files in both folders, we are adding samples for those files (they are called
env_file), so you can just go ahead and rename them to
.env. You will also need to add your private key to the
.env file in the testing folder if you plan to use the
.js file. If you plan to use postman, you will need to paste it into the workspace, so make sure that you create it outside the repo. In any case we encourage you to add
.env files to the
.gitignore and never paste you private keys in the code.
