My API key is not working from a week. I regenerate new key still its not working. I am using this service from 3 years. Using this as endpoint “https://api.company-information.service.gov.uk/company/02075721/filing-history” for using new and existing key getting no result, there is no error generated.
How can I know my key is valid or not and how many days it will take to activate new key?
