Localize exposes much of its functionality via the Localize REST API to make it easier for you to automate your workflow and integrate Localize with your existing tools.
This can be especially useful when localizing mobile apps.
API calls rate limit
For performance and security reasons, there is a 5000 calls-per-hour rate limit for the REST API. Any calls exceeding this limit will return with a 401 error: "Too many requests".
