Headers, Cookies & Paths

For all requests, certain details can be provided through headers, paths or cookies

Request Origin

Identifies the source of a request (such as application, user geolocation), and can be populated using:

• "Rierino-Origin" Header: As base64 encoded Json string

• "Rierino-Origin" Cookie: As base64 encoded Json string

• "User-Agent" Header: Sets origin.agent

• "Referrer" Header: Sets origin.referrer

• "X-Forwarded-For", "Forwarded" Headers, Request Address: Sets origin.ip

Authentication

Provides authentication details (such as credentials, api key or tokens), and can be populated using:

• "Rierino-Auth.[parameter]" Header: Sets auth.parameter

• "Rierino-Auth.[parameter]" Cookie: Sets auth.parameter

• "Bearer" Authorization Header: As base64 encoded Json string prefixed with "base64="

• "Bearer" Authorization Header: As comma separated "parameter:value,parameter:value" pairs prefixed with "multi="

• "Basic" Authorization Header: As base64 encoded username:password parameters

• "[parameter]" Authorization Header: Sets auth.parameter where comma separated "parameter value, parameter value" pairs are allowed

Branch

For sending requests for a specific "branch", two alternative methods can be used:

• {channel} can be suffixed with @{branch}, such as rpc@beta

• Sending branch as "X-Branch" header, such as X-Branch=beta

Async Requests

For making API calls that should fire & forget, a special "X-Async" header can be used with 2 alternative values:

• gateway: The request is received at the API gateway and immediately returned to the requestor with a request ID (even if the backend is not accessible). The gateway keeps communication ongoing with the backend as long as the process runs.

• backend: The request is forwarded to the backend as a fire & forget saga call, and the backend returns a dedicated process ID. The backend keeps running but the communication between gateway and backend is completed immediately.

In addition to async request header, sagas can be individually configured to be fire & forget in nature, which immediately return regardless of this header.
