Based in the United States, Shift4 is a payment processing company. Merchants can accept Mastercard and Visa cards alongside EPS, Giropay, iDEAL, and Sofort bank redirects. Every listed method supports refunds and manual capture, while mandates are not supported. Card payments can use optional 3DS, and webhooks cover payment and refund updates. ### Status and capabilities **Integration status:** live **Category:** payment gateway **Webhook flows:** payments, refunds | Payment method | Type | Mandates | Refunds | Capture methods | 3DS | Card networks | Countries | Currencies | | -------------- | ----------- | ------------- | --------- | --------------------------------------- | ------------------- | ---------------- | ------------------------------------------------- | ------------------------------------------------- | | bank redirect | EPS | not supported | supported | automatic, manual, sequential automatic | not applicable | - | AUT | EUR | | bank redirect | Giropay | not supported | supported | automatic, manual, sequential automatic | not applicable | - | DEU | EUR | | bank redirect | iDEAL | not supported | supported | automatic, manual, sequential automatic | not applicable | - | NLD | EUR | | bank redirect | Sofort | not supported | supported | automatic, manual, sequential automatic | not applicable | - | 12 ([full list](https://hyperswitch.io/pm-list)) | CHF, EUR | | card | Credit Card | not supported | supported | automatic, manual, sequential automatic | supported, optional | Mastercard, Visa | 247 ([full list](https://hyperswitch.io/pm-list)) | 154 ([full list](https://hyperswitch.io/pm-list)) | | card | Debit Card | not supported | supported | automatic, manual, sequential automatic | supported, optional | Mastercard, Visa | 247 ([full list](https://hyperswitch.io/pm-list)) | 154 ([full list](https://hyperswitch.io/pm-list)) | ### Authentication Supply the raw Shift4 API key in the connector configuration. Hyperswitch appends a colon, Base64-encodes `api_key:`, and sends the result with the HTTP Basic scheme. See [`Shift4AuthType::try_from()`](https://github.com/juspay/hyperswitch/blob/740e642eabb5b54094f589d4ebc08aa9e796fab1/crates/hyperswitch_connectors/src/connectors/shift4/transformers.rs#L837-L850) and [`get_auth_header()`](https://github.com/juspay/hyperswitch/blob/740e642eabb5b54094f589d4ebc08aa9e796fab1/crates/hyperswitch_connectors/src/connectors/shift4.rs#L112-L126). ### Before you start 1. Register with Shift4 at [shift4.com](https://www.shift4.com/). 2. Create or sign in to your account in the [Hyperswitch control center](https://app.hyperswitch.io/). 3. Find the API key on the Home page of your Shift4 dashboard. 4. Enable the same payment methods in Shift4 that you plan to select in Hyperswitch. 5. Have the credential listed in [Authentication](#authentication) ready. To connect Shift4 to your Hyperswitch account, follow [Activate a connector on Hyperswitch](/integrations/connectors-integrations/activate-connector-on-hyperswitch.md), then return here for what Shift4 supports. ### Webhooks Register the Hyperswitch endpoint in Shift4 using the [standard webhook setup instructions](https://docs.hyperswitch.io/integration-guide/webhooks). The Shift4 connector does not implement a connector-specific source-verification method, so apply verification controls before enabling incoming events ([webhook implementation](https://github.com/juspay/hyperswitch/blob/93becbaee4ee3686e1a4d5750d2e547c56c27047/crates/hyperswitch_connectors/src/connectors/shift4.rs#L934-L990)). The source enum contains 6 exact variants. Five variants map the wire values below, and the sixth is a catch-all for any other value. The enum applies `SCREAMING_SNAKE_CASE` to incoming values ([enum](https://github.com/juspay/hyperswitch/blob/93becbaee4ee3686e1a4d5750d2e547c56c27047/crates/hyperswitch_connectors/src/connectors/shift4/transformers.rs#L883-L899), [mapping](https://github.com/juspay/hyperswitch/blob/93becbaee4ee3686e1a4d5750d2e547c56c27047/crates/hyperswitch_connectors/src/connectors/shift4/transformers.rs#L1239-L1250)): | Shift4 event | Hyperswitch effect | | ------------------ | ------------------- | | `CHARGE_SUCCEEDED` | Payment processing | | `CHARGE_UPDATED` | Payment processing | | `CHARGE_CAPTURED` | Payment succeeded | | `CHARGE_FAILED` | Payment failed | | `CHARGE_REFUNDED` | Refund succeeded | | Any other value | Event not supported | --- # Agent Instructions This documentation is published with GitBook.

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/shift4.md?ask=&goal= ``` `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.
