Added OAuth 2.0 authorization to Shopping API

[xjxckk]

Added OAuth 2.0 authorization to Shopping API.

Relevant issue: #347

[paddisaap]

Can someone explain me where an how I have to implement this token?
Also where i can get this token from :O

[xjxckk]

You can install my fork, it will get the token for you.

If you want to do it yourself, you can read the discussion here: #347

Thanks for the reply. I added your changes to the scripts but now i'm getting this:

Oauth2.0 token request response: {
"error": "invalid_client",
"error_description": "client authentication failed"
}
Traceback (most recent call last):

Any ideas how I can fix this?
And how do I have to configure my ebay.yaml file/ where do I have to put the OAuth Code in?

[xjxckk]

I updated the imports to include requests for POST.

This is my YAML file:

# Shopping API
open.api.ebay.com:
appid: devid: certid:

@timotheus Do you think you could have a look at this? Just ran into this issue.

[springfielddatarecovery]

Would also like to see this feature implemented

Thanks for the implementation! After reviewing this thread and implementing all suggestions, I generate the access token but end up running into this error:

I would appreciate any leads on how to fix this!

[xjxckk]

Looks like theres some kind of other error occuring, best to go into the source and add prints to see whats going on in your system. I haven't looked at the code for a while.

[dannyo1987]

@xjxckk's fork has a nice solution, but a couple minor bugs. I got a similar error and made a couple minor changes to the code he provided to get it working. Might try my fork.

[jswanson]

Any hope for this fix? Seems like a straight forward approach to solve a problem many people are dealing with.

[pbreezy20]

@dannyo1987 - can you provide a quick guide on how to use your fork? For example, I am looking to use the GetShippingCost function.

[dannyo1987]

You don't have to do anything other than install the fork as a dependency and set up your configuration with your app_id and cert_id

[dannyo1987]

Someone at Ebay should really merge this @timotheus. This api is not that useful without this PR merged. And it's a really nice api, would hate to see it lose its utility!

hey! i'm running into a similar issue - i'm able to generate my Oauth token successfully using the fork above + modifications, but when i make the request i get hit with a similar error. what did you do to resolve? pasting my approach below:

from ebaysdk.shopping import Connection as shopping
shopping_api = shopping(appid="XXX", config_file="ebay.yaml", debug=True)
response = shopping_api.execute('GetSingleItem', {
'ItemID': item_id,
})
print(response)

error:
