Question 1

How do I add SOAP headers using the Elixir Soap library?

Accepted Answer

Pass a tuple of {headers, params} to Soap.call, where headers is a map like %{Token: "foo"}, as shown in the README example. This includes custom headers in the SOAP request.

Question 2

Can the Soap library handle WSDL files with complex XML schemas?

Accepted Answer

It parses WSDL to list operations, but handling of complex types or nested structures might require manual intervention, as the README doesn't detail advanced schema support.

Question 3

SOAP vs REST in Elixir: which client library should I choose?

Accepted Answer

For SOAP services, use Soap for its XML abstraction; for REST, prefer libraries like HTTPoison or Tesla. The choice depends on the API protocol you're integrating with.

Question 4

How to configure the Soap library for SOAP 1.2 protocol?

Accepted Answer

Set the version in your config file with config :soap, :globals, version: "1.2", as specified in the configuration section. It defaults to SOAP 1.1.

Question 5

Does the Soap library support asynchronous SOAP calls?

Accepted Answer

No, the README doesn't mention async support; calls are synchronous. For concurrency, wrap Soap.call in Elixir tasks or use other patterns.

Question 6

What happens if a SOAP call fails in the Elixir Soap library?

Accepted Answer

It likely returns an error tuple, but specific error handling like retries or detailed fault parsing isn't built-in, so you'll need to implement custom logic.
