Power Query to access Open Route maps

[Boleslaw]

Hello,

I am looking for help with my POST request in Power Query. I am trying to use matrix service but with no luck so far. I am receiving the following error:
DataSource.Error: Web.Contents failed to get contents from ‘https://api.openrouteservice.org/v2/matrix/driving-car/’ (400): Bad Request

Here is my code:
let
url = “https://api.openrouteservice.org/v2/matrix/driving-car/”,
headers = [#“Content-Type” = “application/json”,#“Accept”= “application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8”, #“Authorization”= “xxxxxxxxxxxxxxxx”],
postData = Json.FromValue([locations=“[[9.70093,48.477473],[9.207916,49.153868],[37.573242,55.801281],[115.663757,38.106467]]”]),
response = Web.Contents(
url,
[
Headers = headers,
Content = postData
]
),
jsonResponse = Json.Document(response)
in
jsonResponse

I presume the problem is with passing body argument using Json.FromValue

[locations=“[[9.70093,48.477473],[9.207916,49.153868],[37.573242,55.801281],[115.663757,38.106467]]”]

I would be greatful for any hint on how to solve this problem.

Thank you!

Hi @Boleslaw 

Yeah, in PowerQuery lists use "{" instead of "[":

...
postData = Json.FromValue([locations={{9.70093,48.477473},{9.207916,49.153868},{37.573242,55.801281},{115.663757,38.106467}}])
...

Please mark this as answer if it helped.
