billing.tier_upgraded
The creator upgrades to a higher Subscriby tier.
When this fires
The creator switches their Subscriby subscription to a higher-priced tier. Pro-ration is applied through the payment provider, except when the creator is still inside their platform trial, where the switch is not prorated because nothing has been paid yet.
Caveats
- Tier changes can unlock features (e.g. Teams on Growth+); event consumers should refresh tier caches on receipt.
- Pro-ration charges fire
billing.invoice_createdseparately for the proration line (not on an upgrade taken during the platform trial).
