I missed this tweet in the Monzo Love Tweets feed a while ago 
@nmyster has created a really awesome integration between Monzo & his expense management tool (with the expenses details ending in in Salesforce 
), as far as I can tell, the code’s not been published 
but this is a great example of what can be done using Monzo’s API!
