For Messaging, does Bandwidth retry HTTP callbacks if my callback URL is not reachable?


Jessica Murray


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). See the developer docs for how to configure the fallback URL for V1 APIs.
