Stark Bank Merchant Purchase API

openapi: 3.2.0
info:
  title: Stark Bank Balance Merchant Purchase API
  version: v2
  description: 'This is our second API version. It is another small step towards launching the product we want to create for you, but it''s a giant leap for the brazilian financial market. We created the first banking API in Brazil and we are proud of it.

    Our API is RESTFul. This means we use predictable, resource-oriented URLs to do banking operations. The API itself speaks exclusively in JSON, including errors, but our SDK libraries convert responses to appropriate language-specific objects.

    Want to check our OpenAPI 3.1 specification? You can download our yaml file right here.

    You can also try our Postman collection. Download it here.
