Cancellation after confirmation | Ater a /reservations/confirm is initiated, are you preventing your flow from sending a request to /reservations/cancel? | ℹ️ When the process of confirming a reservation is triggered it can't be stopped, so it is important that no requests to /reservations/cancel are sent after one to /reservations/confirm. If a cancellation is needed at this point, you must wait for the confirmation from the carrier and initiate the cancellation flow. | 🟢 Required |
Prices validation | Are you ensuring that the price displayed to users for each step is always taken from the previous API response? | ℹ️ Users should always see the most recent price information before proceeding to the next step. It means that after each API request, the price information should be checked and if any changes occur the new price should be displayed to the user. For example, the final price displayed on the checkout and payment pages must be taken from /reservations/create. | 🟢 Required |
Reservation processing deadline | Are you calling the /reservations/{reservation_id} endpoint repetitively until getting a | ℹ️ Carriers usually take a few seconds to respond to a reservation, with most responding within 10-15 seconds.

Reservation status check frequency | Are you calling the /reservations/{reservation_id} endpoint every 3-10 seconds? | ℹ️ To optimise the user experience and to prevent spamming carriers with requests we suggest calling the /reservations/{reservation_id} endpoint regularly in intervals of 3 to 10 seconds depending on your needs. | 🟢 Required |
Reservation confirm | Are you calling the /reservations/confirm endpoint only once during the flow? | ℹ️ A reservation should only be confirmed once, and making additional call does not speed up the process. | 🟢 Required |

PT Kereta Api Indonesia is one of the only carriers that includes it with every booking. | ⚠️ Required by Indonesia Railways (PT Kereta Api Indonesia) |

Cancellation and amendment policy in email | Does the user receive an email with detailed information on cancellations and amendments? | ℹ️ Users should have clear information on cancellation and amendment policies in the confirmation email or in your platform. Email to customer which includes the ticket should display the text as obtained from the API. If using the standard Distribusion email, this information is available.

Provisional ticket | Is the user informed about how to get permanent tickets? | ℹ️ Tickets deliverd by Trenitalia for their regional network are not valid for travel. This is stated directly on their PDF ticket.

Post Sales
Cancellations | Can users cancel a booking? | ℹ️ Users should be able to cancel a booking directly with you. Ideally, you should offer the ability for users to cancel a booking via your interface. This flow is fully supported by Distribusion API and allows users to view cancellation conditions and cancel a trip. If not supported via your API, you can use the Distribusion Agent Portal to cancel trips. | 🟡 Strongly Recommended ⚠️ Required by DB, Trenitalia, Amtrak |
Asynchronous cancellations | Can users see the status of the cancellation after the cancellation is requested? | Depending on the cancellation conditions and if the booking is flagged as potentially fraud on the SNCF side, the cancellation might be marked as "pending".
