You need no account, no credential and no human sign-in: `GET https://www.gomry.com/api/v1/catalog/events?starts_after=YYYY-MM-DD&starts_before=YYYY-MM-DD&city=`, then `POST https://www.gomry.com/api/v1/checkout_sessions` with the ticket and the buyer's name and email, and send the person the response's `continue_url`: they pay there by card, Apple Pay or Google Pay. To pay yourself with a Stripe Shared Payment Token you need a credential, also with no account and no human: register with `POST https://www.gomry.com/api/mcp/oauth/register` `{"client_name":"","grant_types":["client_credentials"]}` and get a token at `POST https://www.gomry.com/api/mcp/oauth/token` (`grant_type=client_credentials`).
