We have a need to connect to the wootric API. 

We tried setting up a webhook, but as you can not get the auth key in the header as is needed in fivetran the connection is not secure enough for our needs. 
A fivetran connector where we can customize our requests and send data to google storage would be sufficient. And sending the data to BigQuery would be the best solution for us.
