Datanomik Open Banking API review
A REST banking-data API with investment feeds, recurrent links and webhook updates.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Datanomik Open Banking API gives businesses REST endpoints for connecting financial institutions and retrieving structured banking data. It is aimed at corporate treasury teams and financial-data workflows that need account, owner, balance, transaction, investment, payment and cash-flow records. One-shot and recurrent account-link flows let teams choose between a single retrieval and an ongoing connection, while the web platform and API support integration into cloud-based products.
The published commercial model uses contact-sales plans, so organizations should discuss scope and access with Datanomik rather than select from named self-serve tiers. The API’s breadth is a central strength: account and balance-history endpoints sit alongside transaction categories and summaries, investment data, payment records and cash-flow information. Historical and update webhooks for recurrent links add event-driven delivery to the retrieval model. An unlimited sample-data sandbox gives development teams room to build and validate request flows before connecting live institutions.
Integration uses API-key authentication through HTTP Basic and is exposed through REST, with documented real-time refresh and webhook support. Datanomik lists coverage in Brazil and Uruguay, making regional availability an important selection criterion for teams operating elsewhere. Email and documentation are the stated support channels, and the compliance information identifies two-factor support. Choose Datanomik when investment-aware account aggregation, recurrent links and financial-data endpoints matter more than a self-serve buying path. Consider another provider if you need a broader documented geographic footprint, an open-source option or deployment beyond the cloud.
