Authentication

Most messages between the client and Rapyd are authenticated with the values of specific header parameters.

  • REST requests and webhooks contain header parameters for authentication of the messages. See Header Parameters.

  • The signature header parameter for REST requests is calculated according to a specific formula. See Request Signatures.

  • The signature header parameter for webhooks is calculated according to a specific formula. The client can use this information as an additional layer of protection. See Webhook Authentication.

REST responses from Rapyd do not contain headers.

Note

The formula for calculating the signature header parameter differs between REST requests and webhooks. The webhook formula excludes the HTTP method.
