I got the below response from a POST request and want to store the TOKEN value in an variable and use it for future use.

{"AccountName":"tester-01","token":"eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCFtZSI6InN2Yy1kb2NwLXRlc3Rlcjkj5eWSZOSAExHVDL6V9_qgVOJ3pA","refreshvalue":"5X6g8QZ3rk1RWQXLdItXlKnfwTPGjQ==","validFrom":"2021-09-16T05:45:44Z","validTo":"2021-09-16T06:45:44Z"," refreshValidTo":"2021-09-16T11:45:44Z"}

The code snippet for the above response is

   ${body}=  create dictionary       username=test12345    password=12345

   ${header}=    create dictionary       Content-Type=application/json

  ${login}=  post on session  docp  /login  json=${body}    headers=${header}

   ${value}=      Set Variable    ${login['token']}

When I try to set the response in the value variable I get the below error.

Resolving variable '${login['token']}' failed: TypeError: 'Response' object is not subscriptable.

Can someone please help.

When you issue a request the returned data - the login variable in your case - is a response object, not just the payload. It contains as properties the headers, payload, the request that was sent, and a lot others; see the library documentation, where it is described in details.

You're targeting the payload/the content of the respone; as you're dealing with a json api and expect it to be such, there is a convenience method that will return you that, parsed as a python dictionary:

${login}=  post on session  docp  /login  json=${body}    headers=${header}
${payload}=    Set Variable    ${login.json()}    # this will be the data you got from the service, as a plain dictionary 
${value}=      Set Variable    ${payload['token']}
