Data model

Storage

• Webhooks does not own a persistent datastore.
• Payloads are validated and forwarded to Cloud Tasks.

Payload types

• Invoice webhook: partner-sent invoices with headers for idempotency and org routing.
• Bubble sync event: RawEvent from Bubble database triggers.

Idempotency

• Invoice tasks use Idempotency-Key to derive task IDs.
• Bubble tasks use the event id to derive task IDs.

Data ownership

• Webhooks does not own source data; it only validates and forwards payloads.
