Implementation steps

• Create and activate a virtual environment, e.g.

  python3 -m venv venv/

  source venv/bin/activate

Environment variable settings:

• Make a copy of .env.sample, named .env

• Use the following entries:

  • api_url_pattern_basic="https://www.trade-tariff.service.gov.uk/api/v2/commodities/{commodity}"
  • api_url_pattern_filtered="https://www.trade-tariff.service.gov.uk/api/v2/commodities/{commodity}?filter[geographical_area_id]={geographical_area_id}"

Respectively, these URLs are for:

• a commodity API URL with no country filter
• a commodity API URL with a specified country filter

Installation

• Install necessary Python modules via pip3 install -r requirements.txt
• Install dev Python modules via pip3 install -r requirements_dev.txt
