With our unified API, you can support multiple systems through a single, streamlined API. Free up development resources and improve integration quality.

Globally unique identifiers

APIs do not provide globally unique identifiers for entities. Causing the need for large compound keys to identify entities, bloating caches and complicating the code. Our unified API provides globally unique identifiers for all entities, making it easier to identify and track entities.

Actual Consistency

One of the many issues when working with multiple integrations is dealing with the many odd inconsistencies within the same API. From using 'ID', 'Id', 'InvoiceId' all in the same API, using 3 different ways to format dates with occasional timezones, and different ways and limitations on how pagination works, sometimes event omitting important data if you don't pass certain query parameters

Many business platforms, one API

Reach a vast majority of the SME market with just one standardized integration.
