The Upload API, which consists of multiple endpoints, is based on the OpenAPI specification 2.0 ([swagger.io/specification/v2/](https://swagger.io/specification/v2/)). This specification is machine-readable so there is no need to manually upload the API client. To create clients, find a generator which accepts this specification and will create a proxy class, with all appropriate methods, on your chosen platform and in your chosen language. To do this, download the machine-readable .yaml application at [https://api.bsn.cloud/Upload/2019/03/REST/OAS/](https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fapi.bsn.cloud%2FUpload%2F2019%2F03%2FREST%2FOAS%2F\&data=05%7C01%7Csmulqueen%40brightsign.biz%7C0e158b6db7294b0fb48108da23d8ccee%7C8fbcdf641ab847cebdc743e23b04fb3c%7C0%7C0%7C637861711331602708%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C\&sdata=wdqC7%2BF8%2FG%2FQgtsfwWd4HbdR7YAZsptCpKycGyYdQa4%3D\&reserved=0)
