Please note this version of the API is deprecated. You should use Search V3 instead.

The API gives access to carpool trips on BlaBlaCar. The results are identical to those obtained for a similar search on the associated website. Each trip result includes a "links" object to get more details on this specific trip and you should use them instead of trying to reconstruct them.

The base URL is:

https://public-api.blablacar.com

It's a REST API, available only with GET queries.
You can transmit you API KEY either with the `key` parameter, either as a query parameter or as an HTTP header:

Using an API key:

https://public-api.blablacar.com/api/v2/trips?key=XXX&fn=Paris

Using an HTTP header:

curl -H 'key: XXX' https://public-api.blablacar.com/api/v2/trips?fn=Paris

NB: for simplification, the following examples are given without authentication

How to redirect to Blablacar website?

Each trip result includes a "links" object to get more details on this specific trip.
There are 2 links that you could use:

_front point to the same trip on the website
_self point to the direct object on the API

links: {
    _self: "https://api.blablacar.com/api/v2/trips/1234567-neuilly-sur-seine-tille",
    _front: "https://www.blablacar.co.uk/trip-neuilly-sur-seine-tille-1234567",
}

Most of the time, it's the _front link that you will need to redirect users to the BlaBlaCar's trip page, after the concatenation of your marketing/campaign code:

?comuto_cmkt=MARKETING_CODE&utm_campaign=CAMPAIGN&utm_medium=API&utm_source=SOURCE&utm_content=WHATYOUWANT

This page is deep-linked and the website will detect if it's a mobile device and if the BlaBlaCar's app is on the device. In such a case, the user will be redirected to the app.
