Hello Team,
I have multiple questions regarding Authentication Token part. Please find them below:
1. How we validate that the current/previously requested token is yet valid or not
2. What is the limit of authentication token per day and per minute.
3. Could you please give example of how we can limit authentication token request to not exceed.
Thank you,
Trisha Gehlot

Hi @trisha.gehlot,
Once an expired token is used in an API call, the response status code will be HTTP 401 Unauthorized, with the following response message:
{
'error': {
'message': 'Authentication request failed because of invalid token'
}
}0

Hello @trisha.gehlot,
There is a token validation endpoint that you can use - https://selectapi.datascope.refinitiv.com/RestApi/v1/Authentication/ValidateToken(Token='****')
An OAuth token from DSS service is valid for 24 hours, so the best practice is to store the existing token in a file or environment setting along with the timestamp of when it was retrieved, and then reuse this information for subsequent API calls.

Hello @trisha.gehlot,
This link is a part of API reference here, but reading about its documentation - it states that this endpoint has been deprecated and to not use it for new development.
Instead the recommended action seems to be to use a token, and if the existing token is invalid, the app will receive an authorization error. At this point RequestToken method should be used to get a new token.

For limitations, please check the LSEG DataScope Select Best Practices & Fair Usage Policy guide in the REST API-Specific Limits section.

Hi @trisha.gehlot,
Your app can timestamp the expiry time (+24HRS) when it receives a new token. It is not explicitly provided by the server.

Sure, Thank you @Gurpreet !!
that could be one option.
One more question on authentication token, is token associated with userid or Jobs.
For Example, we got a new authentication token while running a job, so do we can reuse the same for another job request or we have to request new token??

Token is connected to the user who requested it. Same token can be used for multiple requests, but care must be taken to not breach the data limits imposed by the product.0
