| We're about to look at ticket ownership proofs. However, you might | ||
| not have a ticket yet! Fortunately, tickets are just PODs, so you | ||
| can generate a self-signed ticket like this: | ||
| <code className="block text-xs font-base rounded-md p-2 whitespace-pre-wrap"> | ||
| {` | ||
| const ticketData = { | ||
| ticketId: "302bdf00-60d9-4b0c-a07b-a6ef64d27a71", | ||

| productId: "${PRODUCT_ID}", | ||

| ticketSecret: "secret123", | ||
| timestampConsumed: 1714857600, | ||
| timestampSigned: 1714857600, | ||
| attendeeSemaphoreId: ${identityV3}, | ||
| owner: "${publicKey}", | ||
| isConsumed: 0, | ||
| isRevoked: 0, | ||
| ticketCategory: 0, | ||
| attendeeName: "John Doe", | ||
| attendeeEmail: "[email protected]" | ||
| }; | ||
| const entries = TicketSpec.parseEntries(ticketData, { coerce: true }); | ||
| const pod = await z.pod.sign(entries); | ||
| await z.pod.insert(pod); | ||
| `} | ||
