Exception handling

Learn more about error codes in the official doc.

The plugin may raise the following exceptions:

• lokalise.errors.ClientError - generic error.

• lokalise.errors.BadRequest (400) - the provided request is incorrect, often due to missing a required parameter.

• lokalise.errors.Unauthorized (401) - API token is incorrect.

• lokalise.errors.Forbidden (403) - authenticated user does not have sufficient rights to perform the desired action.

• lokalise.errors.NotFound (404) - the provided endpoint (resource) cannot be found.

• lokalise.errors.MethodNowAllowed (405) - HTTP request with the provided verb is not supported by the endpoint.

• lokalise.errors.NotAcceptable (406) - posted resource is malformed.

• lokalise.errors.Conflict (409) - request conflicts with another request.

• lokalise.errors.ContentTooLarge (413)

• lokalise.errors.Locked (423) - your token is used simultaneously in multiple requests.

• lokalise.errors.TooManyRequests (429) - too many requests hit the API too quickly (check the section below to learn more).

• lokalise.errors.ServerError (500).

• lokalise.errors.BadGateway (502).

• lokalise.errors.ServiceUnavailable (503).

• lokalise.errors.GatewayTimeout (504).

To handle an exception you would do the following:

try:
    project = client.project("invalid")
except errors.BadRequest as e:
    print("=== Lokalise API Error ===")
    print("Type:", type(e).__name__)
    print("Status code:", e.status_code)
    print("Message:", e.message)
    print("Headers:", e.headers)
    print("Raw text:", e.raw_text)

    if e.parsed:
        print("--- Parsed error ---")
        print("Parsed status:", e.parsed.status)
        print("Parsed message:", e.parsed.message)
        print("Parsed reason:", e.parsed.reason)
        print("Parsed code:", e.parsed.code)
        print("Parsed details:", e.parsed.details)

Rate limits

Access to all endpoints is limited to 6 requests per second from 14 September, 2021. This limit is applied per API token and per IP address. If you exceed the limit, a 429 HTTP status code will be returned and the corresponding exception will be raised that you should handle properly. To handle such errors, we recommend an exponential backoff mechanism with a limited number of retries.
