Hello,
The OpenALPR cloud service used to accept multiple countries but this is no longer possible.
The Cloud API only specifies a string field for the country which only accepts a single country.

Request URL:
https://api.openalpr.com/v2/recognize_bytes?secret_key=sk_DEMODEMODEMODEMO&recognize_vehicle=0&country=eu,gb&return_image=0&topn=10
I see the following response:
{"error_code": 400, "error": "Could not initialize OpenALPR with given parameters"}

Changing the request to only specify a single country (eu) allowed the request to work.

This is a recent change as I was testing about 2 weeks ago with multiple countries and it was working.
Please can you check the integration API is correct and update it accordingly: (https://github.com/openalpr/cloudapi/blob/master/javascript/src/api/DefaultApi.js)

• this still shows allowing multiple comma separated countries)

Best regards, Simon.
