This example repository demonstrates how one can securely display Card data back to users, using Basis Theory iOS. For full details on what every part of the code is doing, visit our official blueprint.

Create a .env file in the backend folder with the following values (or copy from .env.example):

# Card issuer values. Credential is added as value to 'Authorization' header.
ISSUER_GET_CARD_URL=
ISSUER_CREDENTIAL=

# Card ID for Basis Theory (BT)
BT_CARD_ID=

# Basis Theory API Keys
BT_PUBLIC_API_KEY=
BT_PRIVATE_API_KEY=
BT_MGMT_API_KEY=

The Public Application needs to have token:create permission.

The Private Application needs to have token:read and token:use permissions on the /pci/ container with reveal transform.

The Management Application needs to have proxy: create permission.

To start the Express.js backend, simply run the following command from the backend folder:

yarn start

Create a Env.plist file with the following values (or copy from .Env.plist.example):

• issuerCardId -> Id for the Card that you want to fetch from the third party issuer.
• btCardId -> Id for the Card that you want to fetch from Basis Theory.
• proxyKey -> Key obtained from the response of /create-proxy from the backend.
• btPublicKey -> Your public Basis Theory API Key.

Open the DisplayIssuedCards project inside the ios folder on Xcode and run it.

Click on Reveal from the app to watch the Card values get filled.
