Payment extensions

Learn how to integrate with additional payment providers.

Payment extensions allow you to support additional payment providers that aren't integrated with InStore by default. Custom implementations can be integrated for credit cards, gift cards, digital wallet, and pay on account. Each custom payment extension needs to implement predefined InStore endpoints for that tender type. The InStore payment extension proxy sends requests to the URL that you preregister in the InStore Center with the results of the process executed in your in-store application.

Set up a custom payment extension

The specific details of setting up a custom extension and verifying the signature may vary depending on the programming language, framework, and server setup you are using.

To set up a custom payment extension, do the following:

Set up endpoints on your server to receive the custom payment extension data. You need to create a script or program that listens for incoming requests at a specific URL and supports all endpoints defined for the payment type of the particular extension. You can do this using a variety of programming languages and frameworks, depending on your server setup. InStore sends HTTP POST and GET requests to the URL you specify.
Make sure all endpoints are set up to receive data in JSON format. This means that your script or program should expect to receive data in the format of a JSON object, with properties and values that match the data being sent from InStore.
Configure all endpoints to verify the SHA256 hashed signature that InStore sends with each request. This signature is a security measure that ensures that the data being sent to your endpoint is actually coming from InStore and has not been tampered with in transit.
To verify the signature, you'll need to perform the following steps:
1. Extract the signature from the incoming proxy request headers. The header key for the signature is typically named verification-signature.
2. Use your own private key and the incoming request body to generate a SHA256 hash.
3. Compare the generated hash to the signature included in the incoming request headers. If they match, the data has not been tampered with and can be safely processed by your endpoint.
4. Once you've verified the signature, you can process the incoming data as needed. This may involve storing it in a database, triggering other actions in your system, or sending a response back to acknowledge receipt of the request.

All requests and responses are JSON formatted.
