Can't Refresh User Access Token using refresh_token

[madao0492]

I am Japanese and not good at English.

I'm using a translation site, so I'm sorry if my grammar is incorrect.

I am currently testing the authentication function in the Sandbox environment.

The first time I obtained a User Access Token, it worked, but when I tried to refresh the Access Token using the obtained refresh_token, I got a 500 error.

#cURL command in Linux
curl -X POST 'https://api.sandbox.ebay.com/identity/v1/oauth2/token' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Authorization: Basic *****' -d 'grant_type=refresh_token&refresh_token=*****&scope=https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2Fcommerce.identity.readonly+https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2Fcommerce.identity.name.readonly+https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2 Fcommerce.identity.address.readonly+https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2Fcommerce.identity.email.readonly+https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2Fcommerce.identity.phone.readonly'

#Error
{"error":"server_error","error_description":"server encountered an unexpected condition that prevented it from fulfilling the request"}

#Other
- I don't think there's any mistake because I'm using the same "OAuth credentials" as when I first obtained the Access Token.
- I'm using a URL-encoded refresh_token.

I also tried implementing the following Python code, but the result was the same (500 error).

#Python code
req_header = {
　　　"Content-Type": "application/x-www-form-urlencoded",
　　　"Authorization": "Basic " + (base64.b64encode((appID+":"+certID).encode())).decode("utf-8"),
}
req_data = {
　　　"grant_type": "refresh_token",
　　　"refresh_token": aToken_Refresh,
　　　"scope": token_scope,
}

req = urllib.request.Request(get_token_url_sandbox, data=urllib.parse.urlencode(req_data).encode(), headers=req_header)
aToken = urllib.request.urlopen(req)
json.loads(aToken.read())

Can you tell me what's wrong?

Thank you.

There is an issue with the sandbox. I faced the same issue, but when I tried with the production environment, it worked fine. I was able to refresh the access token.

Thank you for your reply.

I understand that it was a problem with the sandbox environment. 

I was relieved to find out that it wasn't my program that was causing the problem.

Hi @jagadegos0  @madao0492 

Refresh token API call is failing with the error code 500 "Internal server error" in the Sandbox. We are aware of the issue and actively working to get it fixed. 

You can check the API Status page: https://developer.ebay.com/support/api-status  to stay updated on current system issues with eBay APIs.

Hello developer_support@ebay ,

It seems like this issue has come back and I do not see it acknowledged in the api status page.
