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. - Upper Tier · D (84.73 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397931426 - Orchestra Tier Right · KK (89.74 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940751 - Orchestra Tier Left · KK (92.25 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940750 - Orchestra Tier Ctr · KK (94.76 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397931424 - Grand Tier · F (97.27 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940746 - Grand Tier · G (102.28 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940744 - Promenade · G (111.05 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940754 - Promenade · H (116.07 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940752 - Orchestra Ctr · G (158.69 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940747 - Orchestra Right · M (176.24 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940749 - Orchestra Left · M (178.74 USD): https://www.gomry.com/event/Choral-Arts-Society-of-Washington-Facing-The-Unknown-Brahms-Requiem-3NZr4dddpFUgMafb6gH1/getTickets?utm_medium=web&utm_campaign=catalogApi&ticket_type=external%3Aticketnetwork%253A1397940748 ## 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%3A1397931426", "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.
