[BUG]: [SHIFT4] Connector returning Sofort Payment Method Type Not Supported but Integration Exists

Feature Description/Summary

Shift4 is a global payments platform that allows merchants to process transactions across multiple payment methods. In the current Hyperswitch integration with Shift4, while attempting to process payments using the sofort payment method, the connector API responds with an error that the payment method is not supported.

Context

While running authorization flows in Hyperswitch using the Shift4 connector, the following error is consistently observed:

ErrorResponse { error: ApiErrorResponse { code: None, message: "Payment method type sofort not supported" } }

Starter Tasks

• Go ahead to the connector documentation and check if the connector (Shift4) even supports Sofort.
• Check the request and response schemas for Sofort in Shift4 and if there exists any disparity between the documentation and hyperswitch's integration, fix that issue.
• Check in all the config files that the particular country currency mentioned for Shift4's Sofort Payment Method is correct or not.
• If at all the connector doesn't support sofort then, in the list of SupportedPaymentMethods, remove Sofort.

Implementation Hints

• You can go to crates/hyperswitch_connectors/src/connectors/shift4.rs and crates/hyperswitch_connectors/src/connectors/shift4/transformers.rs and make relevant changes according to what's gone in the current integration.
• Head to this documentation to get some clarity about the request and response schemas : URL

Acceptance Criteria

• Request and Response body added for each of the flows where integrity check is applied.
• All the required GitHub checks passing
• Formatted the code using cargo +nightly fmt --all

How to Test it

• Create a Merchant Account in local
• Create an API Key
• Add the connector - Shift4
• Test out the flows
