How does the EventSub subscription works?

@Lectamenop

When someone subscribe for more than 1 month at once, will the subscribe event trigger every month until the sub is finished ? Because there is no sub duration in the event…

No,

you’ll get a message on channel.subscribe when they sub
you’ll get a message on channel.subscription.end when/if the sub expires
you’ll get a message on channel.subscription.message if/when they share the monthly message in chat.

I saw that there is a [Channel Subscription Message] event with the information I need but i think this one is only triggered if the user agree to send the message in the chat, am I right ?

Correct, it’s a copy of the messages sent to chat

@Lectamenop

What events are triggered if someone resub or upgrade his sub (going from T1 to T2 for instance) ?

Off hand I don’t know.

I expected a channel.subscribe with the new parameters (the tier) of the subscription.
