Does Bandwidth retry HTTP messaging callbacks if my callback URL isn't reachable?Follow
It depends on what HTTP API platform you are using. HTTP V2 Messaging APIs retry for up to 24 hours in the event your callback server is unreachable. HTTP V1 Messaging APIs offer a fallback URL (once to the primary URL and, if that is unreachable, then to the secondary URL). Check out our developer docs for information on how to configure the fallback URL for V1 APIs.
