Signing API requests

An extra layer of security on top of API keys

The Finqware API v1 has two base endpoints:

• https://api.finqware.com/v1 - protected by TLS & API keys

• https://api.finqware.com/v1s - extra security: message signing & anti-tampering

In order to use the v1s endpoints, an external API consumer is required to sign a short-lived JWT with each API call and include the JWS inside an Authorization header. The signed JWT payload will include a digest (sha256) of the request, for anti-tampering protection.
