# SOAP API

The API reference for the SOAP API

<figure><img src="https://855896703-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F4UWkWFnnmVPzvJTdMtC0%2Fuploads%2FJvsWLlCpk4vU7KWvtjwG%2FSOAP%20API%20B.png?alt=media&amp;token=a0ba85ad-82a9-4330-8932-40cf328fc318" alt=""><figcaption></figcaption></figure>

Our SOAP API is continuously maintained and can be used as an alternative to the [REST API](/api-reference/rest-api.md) and our [other integration options](/documentation/getting-started/integration-options.md). You can access everything via the CardProcAPI service.

We recommend following [our SOAP integration guide](/documentation/getting-started/integration-options/soap-api.md) and using [svcutil](https://learn.microsoft.com/en-us/dotnet/framework/wcf/servicemodel-metadata-utility-tool-svcutil-exe) to start using the SOAP API. This way you will have ready-made CardProcessClient class to help you use the service.

```csharp
class Test
{
    static void Main()
    {
        CardProcessClient client = new CardProcessClient();

        // Use the 'client' variable to call operations on the service.

        // Always close the client.
        client.Close();
    }
}
```

{% endtab %}

{% tab title="Visual Basic" %}

```visual-basic
Class Test
    Shared Sub Main()
        Dim client As CardProcessClient = New CardProcessClient()
        ' Use the 'client' variable to call operations on the service.

        ' Always close the client.
        client.Close()
    End Sub
End Class
```

# 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.number.tech/api-reference/soap-api.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.
