Fidel API

Turn card-linked transaction data into instant customer answers

Card-linked intelligence on demand

From real-time transaction lookups to loyalty offer management, your AI agent accesses Fidel API's card-linking infrastructure the moment a customer needs answers.

Fidel API

Use Cases

Loyalty conversations, resolved instantly

Real scenarios where AI handles card-linked offer questions, transaction lookups, and rewards program inquiries so your team focuses on growth.

Cashback Confirmation in Real Time

A rewards member messages asking if their purchase at a participating retailer earned cashback. Your AI Agent queries Fidel API's transaction list filtered by their card ID and the merchant location, finds the matching transaction, and confirms the cashback amount earned. The customer gets a definitive answer in seconds. Your support team never sees the ticket.

Nearby Rewards Discovery for Shoppers

A loyalty program member asks where they can earn points near their office. Your AI Agent retrieves participating locations from Fidel API filtered by the program and area, then lists the closest stores with qualifying offers. The member discovers three participating cafes within a block. Engagement goes up without a single marketing email.

Enrolled Card Verification Before a Purchase

A customer is about to make a large purchase and wants to confirm their Visa ending in 4823 is linked to the rewards program. Your AI Agent checks Fidel API for active cards under their account, confirms enrollment and active status, and reassures the customer before checkout. Purchase confidence increases and card-linking drop-offs decrease.

FAQs

Frequently Asked Questions

How does the AI agent look up a customer's card-linked transactions?

The agent calls Fidel API's List Transactions endpoint, filtering by card ID, program ID, or date range. It returns transaction amount, currency, merchant location, and timestamp. Sensitive card details like full PAN are never exposed, as Fidel API uses tokenized card references throughout.

Can the agent check if a specific card is enrolled in our loyalty program?

Yes. The agent queries the List Cards endpoint filtered by your program ID and the customer's account. It returns card status, enrollment date, and metadata. The customer gets confirmation without sharing full card numbers, since Fidel API only returns tokenized identifiers.

What authentication does Tars need for Fidel API?

You provide your Fidel API secret key, which you generate from your Fidel dashboard. This key authenticates all API requests. Use a live key for production data or a test key during setup. You can rotate or revoke the key at any time from your Fidel dashboard.

Does Tars store transaction data from Fidel API?

No. Transaction data is fetched from Fidel API in real time during each conversation. The agent retrieves only what is needed to answer the customer's question, and nothing is persisted in a Tars database. Your financial data remains within Fidel's PCI-compliant infrastructure.

Can the agent tell customers which offers qualify at a specific store?

Yes. The agent calls the List Offers endpoint with a location ID or brand filter, then presents active offers with their discount type, qualifying amount, and valid dates. If no offers match the requested store, the agent can suggest nearby participating locations instead.

How is this different from Fidel API's webhook notifications?

Fidel webhooks push transaction events to your server for backend processing. Tars AI Agents handle the customer-facing side, answering questions and retrieving data on demand during conversations. They complement each other: webhooks trigger internal workflows, and the agent resolves customer inquiries.

What happens if a transaction hasn't cleared yet when a customer asks?

Fidel API surfaces both authorization and clearing events. If the agent finds an auth event but no clearing, it informs the customer that the transaction is pending and explains the typical clearing timeline. This prevents confusion and reduces follow-up questions.

Can the agent handle multi-brand loyalty programs with different offer rules?

Yes. Fidel API organizes data by program, brand, and location. The agent can filter offers and transactions at any level, so even programs spanning dozens of retail brands return accurate, brand-specific results for the customer asking.

“Powerful tool - and there's so much more still to explore!”
I love the flexibility of the TARS chatbot design tool. The ability to drop in a new gambit and easily de-link and re-link gambits before and after it saves HOURS of time lost if I had to regenerate from scratch. TARS stands out for its flexibility, consistent performance, and outstanding support.

TARS is an essential tool within our lead gen strategy. I started to use it a couple years ago, and the platform evolved to focus on results. You can integrate your Google Analytics, Facebook Pixel, and AdWords conversion tag to track results and measure your campaign. You can also integrate with Zapier, which opens a lot of possibilities.
