Getting Started

Fidel API provides a developer-friendly, secure and reliable API for businesses to link payment cards with mobile and web applications. Through a single API, developers can securely access data from the three major card networks and build their applications on top of the powerful payments infrastructure.

Card numbers are instantly tokenised and we return to you a unique token that identifies each successfully linked card on your database. You should save the id of the card object that is returned inside your user's object. Every transaction we will send to you will have a cardId that you can use to identify the user that made that transaction.

1. Create an account

First step is to create a Fidel API developer account that will give you access to the developers' dashboard, card-linked program configuration, sandbox environment and test API keys.

2. Get API keys

After you created an account, in your account page on the dashboard, you will find two SDK keys and two API keys. The SDK keys are used to link the web and mobile SDKs to your account and the API keys to access the API endpoints directly. See API Reference. To access the test environment data you must use the test keys and to access the live environment data use the live keys.

Your SDK and API keys are displayed in your account page

API keys

When you're ready to go live with your integration and test with plastic credit/debit cards on VISA, Mastercard and American Express networks you can request access to the live keys by using the test-live switch on your dashboard.

3. Install SDKs

You can use the web and mobile SDKs to capture your user’s card number and link cards to your program without the need of additional security implementations on your server-side code.
