# Fiserv

Accept card and wallet payments.

<div align="left"><img src="https://hyperswitch.io/icons/homePageIcons/logos/fiservLogo.svg" alt=""></div>

Fiserv operates as a payment gateway. Its declared card and wallet methods support refunds but not mandates; 3DS is not supported for card payments and does not apply to wallets. Payments can use automatic, manual, or sequential automatic capture, while incoming webhooks are not implemented in this connector.

### Status and capabilities

**Integration status:** sandbox

**Category:** payment gateway

**Webhook flows:** None declared in code

### Authentication

Supply an API Key, API Secret, and Merchant ID in the connector configuration. Hyperswitch uses the API Secret to compute a fresh HMAC-SHA256 authorization signature for each request, and sends the signature with the API key, client request ID, timestamp, and HMAC token type. See [`FiservAuthType::try_from()`](https://github.com/juspay/hyperswitch/blob/2ef1f9ee5bdf65356c3169f4f5db67fa1d4de7bc/crates/hyperswitch_connectors/src/connectors/fiserv/transformers.rs#L733-L749) and [`generate_authorization_signature()`](https://github.com/juspay/hyperswitch/blob/2ef1f9ee5bdf65356c3169f4f5db67fa1d4de7bc/crates/hyperswitch_connectors/src/connectors/fiserv.rs#L67-L127).

### Before you start

1. Register with Fiserv at [fiserv.com](https://www.fiserv.com/).
2. Create or sign in to your account in the [Hyperswitch control center](https://app.hyperswitch.io/).
3. In the Fiserv dashboard, open **Credentials** to find the API Key, API Secret, and Merchant ID.
4. Enable the same payment methods in Fiserv that you plan to select in Hyperswitch.
5. Have the credentials listed in [Authentication](#authentication) ready.

To connect Fiserv to your Hyperswitch account, follow [Activate a connector on Hyperswitch](/integrations/connectors-integrations/activate-connector-on-hyperswitch.md), then return here for what Fiserv supports.

### Webhooks

Fiserv webhooks are not currently processed by this connector. Do not configure Fiserv webhooks as the source of status updates in Hyperswitch. The incoming webhook implementation returns `EventNotSupported` and `WebhooksNotImplemented`; see [`get_webhook_event_type()`](https://github.com/juspay/hyperswitch/blob/2ef1f9ee5bdf65356c3169f4f5db67fa1d4de7bc/crates/hyperswitch_connectors/src/connectors/fiserv.rs#L910-L934).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hyperswitch.io/integrations/connectors-integrations/payment-processor-capabilities/available-connectors/fiserv.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
