Languages
Sets which languages exist and how one is chosen for a given contact. FaPost separates the language content is written in from the languages it is delivered in. The tab reflects that: one field for the source language flows are authored in, one for the languages available to translate into, and one for what to use when neither the contact nor the assistant has said which they want. Adding a language here makes it available in the content manager; it does not translate anything on its own. See Translations.Runtime
How the engine behaves while conversations are running — the limits that keep one assistant from overwhelming a provider or accumulating abandoned work. Two areas: Messaging caps how fast the assistant sends to a single contact. Providers rate-limit per chat, and exceeding the limit costs delivery rather than speed. Flow execution governs how long a paused session waits before it is abandoned, how many times a node is retried before its branch is treated as failed, and what the contact is told when execution cannot continue at all.The session lifetime is worth setting deliberately. Too short and a contact who
steps away comes back to a flow that has forgotten them; too long and abandoned
sessions accumulate — which is what a rising Waiting sessions count on the
dashboard is telling you.Leaving the failure message empty means a failure reaches the contact as
silence.
