Answer 1

Using "To JSON" from RequestsLibrary

If you are using RequestsLibrary to get the JSON data, you can use the To JSON keyword to convert it to an object. You can then use extended variable syntax to access the individual fields.

For example:

| | ${json}= | To JSON | ${response}
| | log to console | \n the token is ${json["generatedToken"]}

Using "Evaluate" from the BuiltIn library

You can use the Evaluate keyword to run the standard python function json.loads to convert a json string to an object. As long as the data doesn't have any triple-quoted strings, this will work:

| | ${json}= | Evaluate | json.loads('''${response}'''} | json
| | log to console | \n the token is ${json["generatedToken"]}

Answer 2

${Ref_Id_Value}    Get Json Value    ${POSTResp.content}    /doInitiateFundsTransferResponseBody/transactionInformation/transactionReferenceNumber

You can use the Get Json Value method, I think.

Answer 3

You can use robotframework-httplibrary then you can get it like this:

${value}= Get Json Value ${json} /generatedToken
