Configurar UK Companies House
Directamente de la definición del conector: dónde encontrar las credenciales, qué permisos necesitan y con qué API habla este adaptador. Proporcionadas en inglés por el autor del conector.
This connector uses the UK Companies House Public Data API v1.
Getting an API key: register a free account at https://developer.company-information.service.gov.uk → 'Manage applications' → 'Create an application' (pick Live or Test) → 'Create new key' → REST. Copy the generated key into COMPANIES_HOUSE_API_KEY. The key is a 36-character ID with dashes (like 1a2b3c4d-5e6f-...), shown under the application's Keys list — not the application name, and not the account password.
Authentication quirk: Companies House uses HTTP Basic Auth where the API key is the username and the password is empty (the canonical curl shape is -u API_KEY:). This adapter mirrors that — leave the password configuration empty.
Reading auth errors: 400 Invalid Authorization header means the value in COMPANIES_HOUSE_API_KEY is not shaped like a key at all (spaces, quotes, an application name) — re-copy the key itself. 401 Invalid Authorization means it is shaped right but Companies House does not recognise it (mistyped, or its application was deleted).
Company numbers: always 8 characters, zero-padded (e.g. 00006400 not 6400). The search endpoint returns matches with the canonical number you can feed into the other tools.
Rate limit: 600 requests per 5-minute window per API key. Returns HTTP 429 with Retry-After when exceeded.
Free: no paid tier required for the Public Data API. Streaming/companies-bulk products require separate registration.
