API Rate Limiting
To protect the platform from being overloaded and maintain a high quality of service to all customers, Wavecell enforces API rate limits for its SMS API.
The rate limit model consists of a per-second request limit applying to every API endpoint. The limit is set to 5,000 requests/second per subaccount with no maximum daily quota.
Tip: If you need to submit a high volume of messages in a short period for bulk scenarios, make sure to use the endpoint allowing to send SMS by batch instead of the single endpoint: it allows you to submit up to 10,000 SMS in a single request.
