This issue has led to the emergence of aggregators that do the work of connecting to bank APIs, which they then provide as a standardized suite to their customers. 

TrueLayer is one of these aggregators. It’s worked with a slew of fintechs, including alt lender Zopa and personal finance management (PFM) chatbot Plum, helping them to connect to banks in the UK by streamlining the integration process.
