As you'd expect the HERE Transit API uses unique IDs for Travel Operators, Bus Stops, Rail Stations, etc.
As in other countries the UK already has an established system for these IDs in the form of ATOC Codes for Operators, NaPTAN Codes for stops, etc.
Does there exist a way to translate between these two systems, or can anyone help on the best method to do so?
Unfortunately no, the IDs used by HERE Transit API are internal HERE Specific Ids and are not compatible with Ids from other systems.

I'm looking to use the lane information from the fleet telematics api to understand what lanes does a specific road have (for example, knowing if a road has a right turn lane). I'm currently querying the LANE_FC tiles for this information. This works, but a lot of the time it seems to return no results for links that do have turning lanes. I noticed that LANE_FC is in "PDE-Premium-Road-Info", so I'm wondering if I need to upgrade to premium to get better lane information.
Thanks!
In general a Freemim plan would have access to all PDE layers. The lane data is usually only available for Major roads like Motorways and also may depend on the region hence if LANE_FC is not returning any data for a tile then most probably there is no data in that tile.
I am using the nearby stations by geocode transit api to return a json result of 3 closest stations. I assumed these would be train/subway stations but the 3 closest to any given dynamic lat & lng are usually bus stations.
Example of my query with parameters: https://transit.api.here.com/v3/stations/by_geocoord.json?center=LAT%2CLNG&radius=350&app_id=APPID&app_code=APPCODE&max=3`
I have read in pervious posts that the ability to use modes such as mode=1 is only available whilst using one of the routing apis.
To cut down on API calls, I do not wish to call google map nearby places api for train/stations and then use those stations in another api call to Here.com to get the distances. I was hoping there was a way I can do it in one call.
I am client side filtering at the moment and only displaying name & distance. I see that if I change my max parameter to 50, i see more results further down which are tube/subway stations but unsure as to how I would go about filtering these out. Also, i see reference to icons but no url's given to access them, where are these located?
I am using ReactJS and the native fetch method for my api request.
Thanks
I expect that you have 3 requirements:
1) names and distances of stations around a specific coordinate, 2) stations should be filtered by only trains/trams(intercity or intracity) and
doesn't include buses and remaining other modes,3) Avoiding multiple API calls:
by_name or by_geocoord API restrict the search based on the modes, though it can fulfil the first requirement
Route transit API returns connection with the transit stations(by train only) and distances as well, based on the arrival and departure coordinates,
https://transit.api.here.com/v3/route.json?app_id=xxxxxxxxx&app_code=xxxxxxxx&modes=intercity_train,bus,light_rail&dep=41.9773,-87.9019&arr=41.8961,-87.6552&time=2019-06-24T07%3A30%3A00#
It seems that the Routing API requires a Lat/Lon pair to be supplied to the Waypoint parameter. I've seen other APIs that allow for the actual address to be passed, instead of the Lat/Lon. I'm wondering if anyone knows of a way to do this with the Here.com API. In many instances I can obtain the Lat/Lon first, but in one instance it's proving to be a headache, especially given the nature of the way that the REST APIs work and the fact that I'm trying to batch-process a small group of addresses at a single time. Any help would be appreciated.
Unfortunately Routing API needs a waypoint in lat, lon and required a Geocoding as a pre-requisite.
Maybe a not so nice workaround if you are facing issues with Geocoding, the Duck Duck Go provides a syntax
https://duckduckgo.com/?q=!here Junghofstraße 14,60311 Frankfurt am Main,Germany, Germany&ia=about
But you will stll have to extract the lat,lon from the final redirected url.
I am working with the Google Analytics Reporting API. The problem I am running in to is that as far as I can tell the city dimension is not necessarily unique (i.e. multiple cities can have the same name.) So in order to filter to a specific city I need something like ga:country=France;ga:city=Paris which works fine, unless I want everything from Paris OR London. But the OR operator has a higher precedence than the AND operator in the filter expressions, and it doesn't look like there is a way to group expressions together.
So,
Are the strings returned by google analytics for ga:city uniquely identifiy a city?
Is there any way to group expressions together like (ga:country=France;ga:city=Paris),(ga:country=UK,ga:city=London)?
If neither of the above, is there any other workaround?
One of the examples on the reference guide is:
Operating system is (Windows OR Macintosh) AND browser is (Firefox OR Chrome):
ga:operatingSystem==Windows,ga:operatingSystem==Macintosh;ga:browser==Firefox,ga:browser==Chrome
In your situation you could do it in the way of (United Kingdom OR France) AND (Paris OR London) but it would still have your problem if there was a paris in the UK or a london in France.
A workaround would be to make one request where you query the cities in France, and a second different request where you query for the cities in the UK. It would mean making more requests but usually in these kind of cases having smaller but more specific requests is better practice. (And probably easier to manage)
I may start working on a project very similar to Hipmunk.com, where it pulls the hotel cost information by calling different APIs (like expedia, orbitz, travelocity, hotels.com etc)
I did some research on this, but I am not able to find any unique hotel id or any field to match the hotels between several API's. Anyone have experience on how can to compare the hotel from expedia with orbitz or travelcity etc?
Thanks
EDIT: Google also doing the same thing http://www.google.com/hotelfinder/
From what I have seen of GDS systems, and these API's there is rarely a unique identifier between systems for e.g. hotels
Airports, airlines and countries have unique ISO identifiers: http://www.iso-code.com/airports.2.html
I would guess you are going to have to have your own internal mapping to identify and disambiguate the properties.

When you get started with hotel APIs, the choice of free ones isn't really that big, see e.g. here for an overview.
The most extensive and accessible one is Expedia's EAN http://developer.ean.com/ which includes Sabre and Venere with unique IDs but still each structured differently.
That is, you are looking into different database tables.
You do get several identifies such as Name, Address, and coordinates, which can serve for unique identification, assuming they are free of errors. Which is an assumption.
