Running a translation project through the connector is not a fully hands-off operation — the operator needs to be able to see and, when necessary, adjust how the site is built:
Webflow access to the site being translated — at minimum the ability to authorize the site for the connector (Sign in with Webflow), and realistically Designer access, so you can inspect how content was built (page text vs component vs CMS vs embed) and answer "where does this text live?" questions.
Webflow Localization enabled on the site, with the target locales added in Webflow's Localization settings — the connector can only deliver translations to locales the site actually has.
A wxrks account with credentials (access key/secret) connected in the connector's Settings.
If you are an agency operating on a client's site, ask the client for Designer access (or a seat) before scoping — most "content is missing" questions are resolved in minutes by clicking the element in the Designer.
