Prismatic is an integration platform designed for B2B software companies to create reusable integrations and deploy customer-specific instances tailored to each customer's unique configurations. The platform's developers opted to use GraphQL instead of a traditional RESTful API due to its flexibility and efficiency in handling varied developer needs without requiring numerous customized endpoints. GraphQL's advantages include allowing precise queries that minimize over- and under-fetching, reducing multiple API calls, and offering self-documenting capabilities with strongly typed schemas that facilitate rapid and independent development for both front-end and back-end developers. Additionally, GraphQL's versatility allows developers to interact with the Prismatic API using their preferred programming languages and tools, enhancing accessibility and usability. The Prismatic API supports experimentation and query crafting through tools like the GraphiQL explorer, providing a user-friendly interface for developers to interact with the API effectively.
