## Ticket types

| ticket type id | name | kind | price | currency | buyable now | per order | approval | sales end |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| `1G7RlZR2umYd9Mjaitsw` | Pavia Trip Ticket | ticket | free | eur | yes | 1–unlimited | no | — |

Prices exclude the service fee. `buyable now` is a boolean, not a count —
remaining stock is the organizer's information and is not published; create
a checkout session to find out whether a given quantity fits.

## Buying this for a person

Two ways, depending on what you can do:

- You can pay with a Stripe Shared Payment Token: buy it yourself through the
  API (see "Buying this through the API" below, when this event has it).
- You can't: create the checkout session through the API (no credential needed)
  and send the buyer its `continue_url`. 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.

## Registration questions

| question id | question | type | required | answerable | options |
| --- | --- | --- | --- | --- | --- |
| `mav23w61yiz9guqcuznis` | I hereby consent to the processing of my data for promotional purposes and accept the Release Form for the use of my images as described in the dedicated document | multipleChoice | yes | yes | I do, I do not |

Send these back as `attendee_answers` (`{ question_id, value }`). A missing
required answer keeps a checkout session unpayable. `dropdown` and
`multipleChoice` answers must match one of the listed options exactly.

## Buying this through the API, end to end

This ticket is free, so any agent can buy it end to end: no payment token.
Call `complete` with a body of `{}`, without `payment_data`.

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 <token>   (omit it if you have no credential)
API-Version: 2025-09-12
Content-Type: application/json

{
  "items": [
    {
      "id": "1G7RlZR2umYd9Mjaitsw",
      "quantity": 1
    }
  ],
  "buyer": {
    "name": "Ada Lovelace",
    "email": "ada@example.com"
  },
  "attendee_answers": [
    {
      "question_id": "mav23w61yiz9guqcuznis",
      "value": "I do"
    }
  ]
}
```

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. Full flow: https://www.gomry.com/auth.md
