Because of memory protection restrictions, Appian does not directly support creating base64 encoded strings.

so is there is any other way to send a document in base 64 string
like any smart service to convert document to base 64

Yes, there are. But not for your specific use case to insert that base64 encoded file into a XML string.

Does that API only understand XML? With JSON, it would just work OOTB.

You could try using this plugin: [mention:e7b082a6b98049899e3541011e57f30e:f7d226abd59f475c9d224a79e3f0ec07]

As Stefan has mentioned, be mindful of the impacts on memory usage when using these approaches.
