XML Formatting

[jrasmussen]

Hi everyone,

I'm currently working on implementing the new Authorize.Net API in a legacy system, and have to manually generate the XML to be posted to the API.  When looking at the API reference, the request XML starts with <createTransactionRequest xmlns="AnetApi/xml/v1/schema/AnetApiSchema.xsd">

My question is whether or not the tag <?xml version="1.0" encoding="utf-8"?> is required.  I'm sending the data in a variable and not a file, so I'm not sure what the best practice is here as I'm still decently new to API work.  Thanks in advance for the help.

Best,

Jonathan Rasmussen.

You can get away with skipping it with Authorize.Net. But, its a good practice to send it.
