Both providers offer some degree of customisation of their widgets. TransactionLink offers fully customisable widget with whitelabel possibility, configurable UI, the possibility to extract consents from the widget and put them in previous steps and full widget CSS customisation. Kontomatik offers only the possibility to change colours of certain elements of the widget.
In both cases the response time depends on the bank, from which the data is being downloaded and it’s performance and the load of the data downloaded, so the latency can vary significantly. For Kontomatik, the global median value of response time is 12 seconds, and for TL AIS the average value is 0.5s
Both Kontomatik and TransactionLink return personal/company data, account information and transactions from the account. Additionally, Kontomatik returns data on credit cards connected to the account and can match them with certain transactions made with them.
Both companies can provide a PESEL number of your users in embedded flow. TransactionLink retrieves PESEL from all but 1 bank, whereas Kontomatik returns full PESEL from 4 banks and a masked PESEL* from another 2 banks.
Neither company offers mobile SDK for their solutions, so their solutions are not friendly to native mobile apps. They both, however, work just fine on mobile websites.
