Why, what problem are you having specifically? Where are you stuck now? I provided you a link to show how to access the message body. Have you used it? Next you need to work out how to parse the numeric value from the message. Is that the issue now...have you researched or tried anything? As a general problem (how to parse specific data from an unstructured set of info) this isn't something new. You should at least be able to get some ideas for possible approaches. It would also help if you can let us know whether the email is HTML or plain text - show us an example of the raw unformatted body — ADyson, Aug 25 '21 at 17:28
