Doubt on allocating case in alpha

I tried to call the task allocate api for allocating the task to the underwriters so here im getting a error unauthorized so what to do ??

in the top i can see a option for authorize when i open that it asks me for a token which token should i give there?? The token which is generated by sandbox-ids ??

Hello @Aswin ,
Yes, if you want to make an API call, you need to authorize it using the IDS token
