They pay there with a card, Apple Pay or Google Pay and no Gomry account. Or send the buyer the link for the ticket they want below. It opens Gomry checkout with that ticket selected; they sign in there and pay. - Reserved 3 · Y (95.15 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1275963311 - Reserved 3 · AA (96.30 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1276033194 - Reserved 3 · S (112.40 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235063957 - Reserved 3 · Q (112.40 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235096949 - Reserved 3 · P (112.40 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235834842 - Reserved 1 · J (113.55 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235063953 - Reserved 4 · M (113.55 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235063971 - Reserved 1 · I (113.55 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235754402 - Reserved 3 · T (113.55 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1236355783 - Reserved 4 · K (114.70 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235061519 - Reserved 4 · L (114.70 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235061524 - Reserved 4 · N (114.70 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235061537 - Reserved 3 · R (114.70 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235096957 - Reserved 4 · O (114.70 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235754409 - Reserved 3 · J (130.80 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1234925129 - Reserved 1 · G (131.95 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1234883061 - Reserved 2 · J (131.95 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1234925862 - Reserved 1 · F (133.10 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235061506 - Reserved 3 · B (251.55 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235063941 - Reserved 2 · A (319.40 USD): https://www.gomry.com/event/Undertale-Live-The-Determination-Symphony-QLHvIjYqujQHZf8PTJBJ/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1235111197 ## Buying this through the API, end to end For an agent that pays with a Stripe Shared Payment Token minted payable to Gomry (see https://www.gomry.com/auth.md#payment). The purchase finishes without the buyer leaving your conversation. No token? Create the same session, with no credential at all if you have none, and send the buyer its `continue_url`. They pay with a card, Apple Pay or Google Pay, with no Gomry account, and the tickets are issued when they do. The `ticket type id` column above is `items[].id` below. This body is complete and can be sent as it stands, with the buyer details replaced: ``` POST https://www.gomry.com/api/v1/checkout_sessions Authorization: Bearer (omit it if you have no credential) API-Version: 2025-09-12 Content-Type: application/json { "items": [ { "id": "external:ticketnetwork%3A1275963311", "quantity": 1 } ], "buyer": { "name": "Ada Lovelace", "email": "ada@example.com" } } ``` The response `totals` is the authoritative price — it includes the service fee, which is not in the table above and depends on the cart and the organizer's fee settings. Never compute a total from this document. Quoting and `continue_url` need no credential. Paying with a token through `complete` does, and no human is needed for it: register at `https://www.gomry.com/api/mcp/oauth/register` for the `client_credentials` grant.
