Generate Hash Code

• SHA256. But this doesn’t use password. Double check with Paulo.

• MD5 . But this is also a one-way algorithm. Double check with Paulo.- WinRest Logic to calculate hash:

• Image Added

• DynamoDB secrets table: rbi-account-secrets

  • rbi/<env>/<brand>/<country>/refill-machine

    • value: {"dispenser_password":"<>" }

  • Reference showing a intl-whitelabel-graphql call to retrieve secret: https://github.com/rbilabs/ctg-whitelabel-graphql/pull/1477

  • store id, transaction id, transaction datetime

• What’s the API that whitelabel needs to call to receive as response the hash to be converted into QR code? What is the response field? Any example?

  • In approach 1, it’s commit order and commit order callback. In approach 2, no external API is needed.

  • Hash: 2bb4193529026315ce6ca36dbc6831ef

• What’s the content of the hash?

  • This field is the result of several fields encrypted with a password provided by the vending machine team: Example:

    • Store ID: 103
      Transaction ID: 84970387 → is it posOrderId?
      Date and time stamp: 20211031013000

• Can the hash content be generated inside RBI app?

  • Yes, it can. But we need the the secret to generate the encoded hash that the vending machine will decode. Besides, we need to configure all items and all stores that grants the right of refill drinks. All the logic would be internal.

• What’s the handle component (sticker) of the bottom?

  • We checked existing storybook component, but no one looks good for it

  • Proposal: create a new one:

  
  • 

  • Example :

    View file
    name App.css

    View file
    name App.js

• What are the icons for 'refill drink' and qr-code ?

  • Follow Menu Brand Icon approach to keep consistency and add new icons in ctg-components-library and import it in Whitelabel :
