Needs `manage_billing`. ## OpenAPI ````yaml /api-reference/openapi.json get /tenants/{tenant}/credit-transactions openapi: 3.1.0 info: title: Need Alert API version: '1' description: >- The Need Alert API lets your own system — an ERP, an online store, a clinic's scheduling software — do what the panel does, without anyone at the screen: keep items in sync, read who is waiting, estimate the cost of an alert, send or schedule it, and follow your credit balance. Authenticate every request with an API key created by the chain owner in the panel (**Integrações**), sent as `Authorization: Bearer `. Always send `Accept: application/json`. Send `Idempotency-Key` on the two creating endpoints so a retry never creates an item or alerts the subscribers twice.
