API Changes Information

Hey guys

I am trying to access companies house api using RestSharp (C#).
Can someone let me know how and where should I be adding the api key?

Many thanks

The Companies House API uses HTTP Basic Authentication to transmit an API key between the client application and the server. Basic authentication is usually made up of a username and password pair; the Companies House API takes the username as the API key and ignores the password, so can be left blank. This is documented on the [developer hub][1].

Iā€™m no expert in RestSharp (C#) but some quick reading indicates that a GET using the client will not encode the username and password so you will have to replace the username, password with the base 64 encoded version of your_api_key plus a colon, as a separator between the username and password is required (NB you will need to append the colon to the end of the api key before encoding)

Hope this helps

Thanks
