Richie Editions App SDKs

Developer guide for app makers

The Richie Editions reader is available as a native SDK, ready to integrate into any iOS or Android app.

The easiest way to get started is to clone one of our demo apps from GitHub. See below for platform-specific instructions.


Fetch the demo app from the richiefi/editions-sdk-example-ios repository at GitHub and follow the instructions in to build and run it.


Fetch the demo app from the richiefi/editions-sdk-example-android repository at GitHub and follow the instructions in to build and run it. An API reference is also available.

Authentication and Entitlements

Customers in the Richie Editions systems are authorized using a JSON Web Token (JWT). Typically, the app will receive the JWT from the publisher's backend system based on the customer's login credentials. The JWT is then passed to the SDK by implementing a TokenProvider that gets called by the SDK when a token is needed to complete an action the customer initiated. The demo apps include an example implementation of a TokenProvider that uses a hard-coded JWT that allows access to limited demo content.

In a production system, the JSON payload would use the following format:

  "iat": 1516239022,
  "exp": 1516339022,
  "ent": [

The iat and exp fields are the standard JWT fields for the issued at and expiration times. The Richie Editions backend will verify that the token is valid for the current time. The ent field is an array of entitlements that the customer has. Each entitlement maps to one or more Richie Editions products. Multiple entitlements can map to the same product, and a single entitlement can map to multiple products. Richie maintains the entitlement-to-product mapping in the backend configuration.

The tokens are signed by the publisher with the ES256 or ES384 signature algorithm. The public key will be configured in the Richie Editions backend.
