Ref vk-io how to get?

Question

In contact with

I use the vk-io library, there is a code

vk.updates.on(['new_message'], async (context, next) => {
console.log(context)
})

But the object does not have many parameters, such as ref and ref_source, for example.
How can you get them?

Answer 1

The context returns the referralSource and referralValue parameters; You can get them by calling context.
