Marvel API and Insomnia (or Postman): how do I pass the hash value that's required?

Follow the steps:

1. Pick an API Endpoint. eg: https://gateway.marvel.com:443/v1/public/characters
2. Use a query value for ts. ts could be timestamp or any long string. eg: ts=thesoer
3. Generate a MD5 hash of ts+privatekey+publickey through code or preferrably online. eg: md5(ts + privKey + pubKey) For md5 hash: http://www.md5.cz/
4. Join the dots. URL?ts=val&apikey=key&hash=md5Hash. eg. https://gateway.marvel.com:443/v1/public/characters?ts=thesoer&apikey=001ac6c73378bbfff488a36141458af2&hash=72e5ed53d1398abb831c3ceec263f18b
