Configure using environment variables

This Singer tap will automatically import any environment variables within the working directory's .env if the --config=ENV is provided, such that config values will be considered if a matching environment variable is set either in the terminal context or in the .env file.

The docs explain how to get your Tally API key.

Testing with Meltano

Note: This tap will work in any Singer environment and does not require Meltano. Examples here are for convenience and to streamline end-to-end orchestration scenarios.

Use Meltano to run an EL pipeline:

# Install meltano
uv tool install meltano

# Test invocation
meltano invoke tap-tally --version

# Run a test EL pipeline
meltano run tap-tally target-jsonl
