A User's data will normally be available in the API or Dashboard within a few minutes of the User seeing the 'Connected' stage of the Widget. However, it can sometimes take up to 10 minutes as the connection to the bank is still in place at this stage as we seek to retrieve the data.
It is almost impossible to estimate how long it will take for data to be returned from specific bank accounts. This is because the time depends on the number of accounts and transactions within each individual's bank account, and also the speed of the specific bank's website.
