Allowed sources
Allowed Sources is the whole of a provider’s authorisation: it can write to those sources and nothing else. That lets you scope integrations — several providers writing to one source, or one provider restricted to a single source.A source’s own page lists the providers that may write to it, in the Providers chip row — see Track usage of source data.
