You need to log into your Betterez backend.

Once logged in, click on the Administration menu and either start typing 'Applications' and click that link, or click on 'Integrations'. If you land on the Integrations page, click on the Applications card.

You will then see a series of applications listed.

You should create a new application for your custom development. This will allow you to use your own public and private keys and rotate those keys as you wish.

Your public api key should be used in the X-API-KEY header when making a request to the Betterez API.

For example in curl you will do this:

curl --request GET \
  --url https://api.betterez.com/inventory/countries \
  --header 'x-api-key: {{x-api-key}}'
