I have setup API using JWT as authentication method. I have my own IDP that generates JWT bases on request values provided to it, Now when I request JWT from my own service and provide it to tyk, it applies policy provided in JWT, In policy I have set expiry of key to one hour. All the keys get expired after an hour. But I need to use the same request values to generate new JWT with new policy that has expiry time as 24 hours. My question is how can I delete existing Api Tokens from the tyk so that I could use same request values to generate new JWT that has applied with new policy ?
