Web APIs (Application Programming Interfaces) facilitate the exchange of resources (data) between two functionally independent entities across a common programmatic interface. In more general terms, Web APIs can connect almost anything to the world wide web. Unlike traditional software, APIs are not compiled, installed, or run. Instead, data are read (or consumed in API speak) through a web-based transaction, where a client makes a request and a server responds. Web APIs can be loosely grouped into two categories within the scope of biodiversity informatics, based on purpose. First, Product APIs deliver data products to end-users. Examples include the Global Biodiversity Information Facility (GBIF) and iNaturalist APIs. Designed and built to solve specific problems, web-based Service APIs are the second type and the focus of this presentation (referred to as Service APIs). Their primary function is to provide on-demand support to existing programmatic processes. Examples of this type include Elasticsearch Suggester API and geolocation, a service that delivers geographic locations from spatial input (latitude and longitude coordinates) (Pejic et al. 2010).
Many challenges lie ahead for biodiversity informatics and the sharing of global biodiversity data (e.g., Blair et al. 2020). Service-driven, standardized web-based Service APIs that adhere to best practices within the scope of biodiversity informatics can provide the transformational change needed to address many of these issues. This presentation will highlight several critical areas of interest in the biodiversity data community, describing how Service APIs can address each individually. The main topics include:
standardized vocabularies,
interoperability of heterogeneous data sources and
data quality assessment and remediation.

Fundamentally, the value of any innovative technical solution can be measured by the extent of community adoption. In the context of Service APIs, adoption takes two primary forms:
financial and temporal investment in the construction of clients that utilize Service APIs and
willingness of the community to integrate Service APIs into their own systems and workflows.

willingness of the community to integrate Service APIs into their own systems and workflows.
To achieve this, Service APIs must be simple, easy to use, pragmatic, and designed with all major stakeholder groups in mind, including users, providers, aggregators, and architects (Anderson et al. 2020Anderson et al. 2020; this study). Unfortunately, many innovative and promising technical solutions have fallen short not because of an inability to solve problems (Verner et al. 2008), rather, they were difficult to use, built in isolation, and/or designed without effective communication with stakeholders. Fortunately, projects such as Darwin Core (Wieczorek et al. 2012), the Integrated Publishing Toolkit (Robertson et al. 2014), and Megadetector (Microsoft 2021) provide the blueprint for successful community adoption of a technological solution within the biodiversity community. The final section of this presentation will examine the often overlooked non-technical aspects of this technical endeavor. Within this context, specifically how following these models can broaden community engagement and bridge the knowledge gap between the major stakeholders, resulting in the successful implementation of Service APIs.
