Finder API authentication/authorisation issues
Answer
8 February 2019 4:53
Dear message board administrator,

Did you change the Finder API authentication/authorisation process?

I seem to be getting 403 HTTP responses when trying to download data when I was getting 200 responses and was able to download the data in the recent past (i.e. middle of January). I am still able to request a token from your token provider but when sending the HTTP request to download I receive the 403 response.

Can you please assist with this query as soon as possible?

PS 1. I have noticed that your EO browser has also changed which was also using the Finder API.
PS 2. Do you have a software amendment/deployment policy that I could read as well please?

Kind regards,
Dimitrios

Dear Dimitrios,

It's strange, because we haven't implemented any changes to EO Browser and Finder API.
The only update we have made is related to ordering new products.
Most probably, the root of the problem is API token lifespan, which is set to 300 seconds and after that another token request should be made.
Of course, you can automatize it by applying script in Python that would refresh your token every five minutes.

Best regards,
Mateusz

Hi Mateusz,

Thanks for your reply - it sounds like a possible solution since revisiting my code I can see that I collect the token for all my areas of interest which may be creating the problem. I will amend the code and come back to mark this as an answer or ask for more details!

Kind regards,
D.

Hi Mateusz ,

Unfortunately that seems not to be the case (i.e. the 300 seconds for each token) - I am running the following script in my ubuntu server machine and still fails with 403 (i.e. just for for one request) - that shouldn't be the case right?

12345678910111213141516171819202122232425
USERNAME=my_user
PASSWORD=my_pass

export KEYCLOAK_TOKEN=$(curl -d 'client_id=CLOUDFERRO_PUBLIC' \
                             -d "username=${USERNAME}" \
                             -d "password=${PASSWORD}" \
                             -d 'grant_type=password' \
                             'https://auth.creodias.eu/auth/realms/DIAS/protocol/openid-connect/token' | \
                             python -m json.tool | grep "access_token" | awk -F\" '{print $4}')

Hi Dimitrios,

Due to backend maintenance works, that I didn't know about, the syntax and address used for requesting downloads has changed, and now it looks like:
https://zipper.creodias.eu/download/product_uuid?token=
rather than
https://finder.creodias.eu/resto/collections/Sentinel1/product_uuid/download?token=

We'll try to apply fix which redirects to the previous address as soon as possible. Meanwhile, please use the new URL for data downloading.
Sorry for misguiding you.

Best regards,
Mateusz

Hi Mateusz,

Thanks for passing my details to your BD team - the links you have included in your previous post do not work though. I am getting a general slack page saying there is no content in those pages.

Kind regards,
D.
