Rate limit in sending messages
Digital Media Bridge assigns to each customer a specific sms send rate limit; this limit is defined as numer of messages / time interval.
Customers can submit messages until rate limit is reached.
If user rate limit is reached, Mediariver will reject every message in request with http 429 status code.
Examples:
| Limit examples | Requests in interval |
| 100/sec | User can send 100 different requests for a single sms in a second. User can send multiple requests for multiple sms (until 100 sms is reached) in a second |
| 1000/5sec | User can send 1000 different request for a single sms in 5 seconds. User can send multiple requests for multiple sms (until 1000 sms is reached) in 5 seconds. |
Digital Media Bridge adds those HTTP headers in every response:
| RateLimit-Retry-After | how long the client should wait before making a new request (ms). |
| RateLimit-Limit | allowed number of messages in time interval. |
| RateLimit-Remaining | remaining messages in current time interval. |
| RateLimit-Reset | next time interval reset date. |
