All of Bandwidth's endpoints are rate limited. ⚠️ Please note that Rate limts are subject to change. You should expect and handle either an
HTTP 429 or
HTTP 403 response for each request to Bandwidth's API.
Endpoints that access resources; such as listing messages, listing transactions, or creating a new application are rate limited at the API level and will return an
HTTP 429 error when the rate limit is exceeded.
The only two endpoints that behave differently are
POST requests to create new SMS/MMS messages or create a new phone call and will receive a
HTTP 403 error when the rate limit is exceeded.
