Please note that the API is throttled, currently 200 requests per minute, per account. Please read Rate Limit section in the Docs.
If your client exceeds this number, a "429- Too Many Requests" status will be returned and this library will retry according to the retry environment variables as configured.
Currently we do not support users increasing the limit by users themselves. This is something we may change in the future. In a meantime, please contact firstname.lastname@example.org for more information.
