Retrieve authentication data from a SOAP endpoint by calling the specified authentication method

Retrieves a WSDL Definition from a given endpoint and returns the raw XML

Makes a request to the SOAP webservice using the specified method

The **Request** action can take optional [SOAP headers](https://www.w3.org/TR/wsdl.html#_soap:header) (which are different from HTTP headers).
You can easily generate SOAP headers that reference config variables and other steps' results using [input templates](integrations/low-code-integration-designer/passing-data-between-steps.mdx#template-inputs):

#### Simple SOAP Request

This example uses this generic [calculator SOAP API](http://www.dneonline.com/calculator.asmx), which presents methods to add, subtract, multiply, and divide two integers.
The API's [WSDL](http://www.dneonline.com/calculator.asmx?wsdl) specifies a **Multiply** operation, which multiplies two integers, `intA` and `intB`, and returns a `MultiplyResponse`.

To use that method, first add a [Get WSDL Definition](#get-wsdl-definition) step to fetch the API's WSDL definition.
Then, reference that definition as the **Request** step's **WSDL Definition input**.
Under **Method**, specify that you want to execute the **Multiply** operation.
Finally, add two **SOAP Parameters** for `intA` and `intB`.
Here, we multiply the integers 7 and 8:

The step's result will match the format that the SOAP API's WSDL specifies.
In this case, it'll return a `MultiplyResponse`.
The result will also include the XML that made up the request and response, in case you need to do additional work with the XML.

**Simple Object Access Protocol** ([SOAP](https://en.wikipedia.org/wiki/SOAP)) is a messaging protocol specification for exchanging structured information with web services.

This component allows you to interact with a SOAP API.
You can fetch WSDL definitions, describe the methods that a SOAP API supports, and make requests of the API's methods.
