Creating image with base 64 byte array returns invalid image v201502

[Vince NexonM]

Following the image documentation

https://developers.google.com/adwords/api/docs/reference/v201502/AdGroupAdService.Image

It's stated that the raw data image should be base 64 byte array, but I kept getting an invalid image error.

I then decided to try the regular byte array, non base 64 format, and it accepted and I can see my image ad in my campaign now. Is that a typo in the documentation or am I reading it wrong?

Hi Vince,

I think that what's happening here is that the SOAP toolkit is performing the base64 encoding for you, so if you base64 encode the value as well, you're double-encoding and that leads to the error.

For example, in the Java client library, the type of the Image.data field is simply byte[], so when creating an Image object I can simply set that field to the raw byte array. However, when the underlying SOAP toolkit (e.g., Apache Axis) builds the message, it base64 encodes those bytes.
