We are just getting started trying to call the API, so doing something basic like a post to action customer_get, but getting an xml response indicating an Invalid API Token. We are taking the token from the admin site advanced tab. Is there some additional treatment for the string we need to apply?
Our curl command looks like this, with the specific items omitted
curl -d "email@example.com" https://mystore.foxycart.com/api
<?xml version='1.0' encoding='UTF-8'?><foxydata><result>ERROR</result><messages><message>Invalid API Token</message></messages></foxydata>
