Payment Source creation results in Bad Request

[kostaskoukouvis]

The new form package does not fully support payment sources. Especially I ran into the problem when trying to create a new three_d_secure source.

What the /v1/sources endpoint expects:

type=three_d_secure&three_d_secure[card]=src_66666666&three_d_secure[customer]=cus_66666666

What is actually being sent:

type=three_d_secure&card=src_6666666&customer=cus_666666666

The problem lies to the fact that the TypeData struct attribute has a wildcard tag form:"*" which results in it being encoded on the same level as the rest of the struct and not as subfields of the type name. I guess this means that there should be a special case in the structEncoder's encode function or on some other level that depending on the payment source Type it gives the correct key name for the TypeData map.

Unless I totally missed something and there already is a proper way of making those requests that hasn't been documented yet.

Go version: 1.8.3
