The hash is a SHA-512 digest computed over a pipe-delimited, ordered concatenation of the request parameters bracketed by the merchant "salt" (a shared secret that is never transmitted). The response is verified the same way (reverse-order hash). There is no OAuth 2.0 / OIDC surface. Test and live use separate key/salt pairs and separate hosts. schemes: - name: merchantKey type: apiKey in: body parameter: key description: Merchant key issued in the Easebuzz dashboard, sent with each request. sources: - https://docs.easebuzz.in/ - name: requestHash type: customHash algorithm: SHA-512 in: body parameter: hash description: >- SHA-512 hash over an ordered, pipe-delimited payload plus the merchant salt, proving request integrity and authenticity.
