The Parallel Markets API allows users to assert their identity and accreditation status on other websites. Users have a portable investor identity that enables authentication and authorization on third party platforms without repeated accreditation verification.
The Parallel Markets API uses the OAuth 2.0 protocol for authentication and authorization. Currently, only the web server OAuth 2.0 scenario is supported. Additional support for installed and client-side applications is currently planned for the near future.
To begin, OAuth 2.0 client credentials will be provided from Parallel Markets support. Then your client application requests an access token from the Authorization Server, extracts a token from the response, and sends the token to the Paralell API that you want to access.
All documentation for the API can be found at developer.parallelmarkets.com.
