Need help getting roundtrip Eurostar ticket from London to Amsterdam

That shouldn't be a problem, are you having problems with their website?

London to Amsterdam round trip for August 2025 isn't being offered yet on Eurostar website. It's probably too early to order ticket. I just wanted to be certain that I could get the ticket without having a cell phone. Thank you.

You don't need a cellphone.
What is an API?

API has something to do with English immigration. When you get Eurostar ticket, there is a form to fill out with immigration info. If you don't fill it out, you won't get ticket.

Yes, that shouldn't be a problem. Wait a few months and you should be able to buy tickets.

I’ve just looked at the Eurostar site.
API is just Advance Passenger Information.
They just want a current email address or phone number to contact you in case of changes and to issue the ticket.
Also your passport number, as you’re going from the UK to the EU.
See their Conditions of Carriage on the website, section 1:4.
You don’t have your “apply” for anything, just put the info in when booking the ticket.

That’s all.

Do you maybe mean ETA, which comes from the UK government? (I've never gotten one, yet.) You'll have one already, because you'll be in the UK. Maybe it has a number that's needed for the API form?

Eurostar open for bookings 6 months out so are currently open to 19 July.

"Maybe it has a number that's needed for the API form?"

There's no number to enter - the Home Office collects your passport number. When carriers transmit the API data, it checks whether you have an ETA, and they get a response of either Board, No Board or Check.

Should I apply for ETA before buying Eurostar ticket for August? Thank you everyone.

Is it correct for me to assume I should apply for ETA prior to getting Eurostar ticket? I think I have to get something similar for entry into Netherlands.

Thank you so very much for your information. I really appreciate it.

I think I have to get something similar for entry into Netherlands.

Maybe.

Depends what your citizenship is.

Hi Pamela

In almost all your posts since you joined us in Fall last year you have asked about the ETA and how to get it, and what you need for entry to the Netherlands, and it been explained each time.

I'm concerned that you don't seem to get it.

It really is pretty straightforward, especially if, like many here you have either a Canadian or USA passport.

Do you have a USA or Canadian passport?

You need the ETA for entrance to the UK as well as a passport. Your previous posts explain how to get the ETA which is valid for 2 years.

At some unknown time in the future the EU, which includes France, Belgium and the Netherlands and many more European countries, ETIAS will come in and be required. There is no date set yet, it is unlikely to be this year, it has been dragging on for many years, and when it will be required there will be plenty of publicity, here on the Forums and in the news. You DO NOT NEED one for your trip.

API, Advance Passenger Information, is required by the UK government before travel from the UK. It is just a couple of questions. You need it to leave the UK.
