I’m trying to attach files (images) to nodes via Services 3 from an external app using JavaScript.

From what I understand (and doing) is:

1) Create a node posting JSON to my endpoint domain.com/api/node.json

{   "type":"foo",   "title":"Hello World",   "language":"und",   "body":{"und":{"0":{"value":"Body Text"}}}, } 

2) Create file posting JSON to my endpoint domain.com/api/file.json

{   "filename":"image.jpg",   "target_uri":"public://image.jpg",   "filemime":"image/jpeg",   "file":"myBase64String" } 

No problem at all at this point.

Then when trying to attach the files created to the node, is where I have trouble, not http errors, simply nothing happens.

First I have tried posting JSON to my endpoint domain.com/api/node/*nid/attach_file after successfully creating a new file, and getting back the fid

{   "field_name":"foo",   "filename":"image.jpg",   "fid":"*fid" } 

Returning Status 200 OK empty text, but when viewing the node remains the same without the file attached.

I have also tried to create the files first and then when posting for node creation adding the fid, the node is created but no file attached.

{   "type":"foo",   "title":"Hello World",   "language":"und",   "body":{"und":{"0":{"value":"Body Text"}}},   "field_foo":{"und":{"0":{"fid":"*fid"}}} } 

My field is a field type Image, widget Image. I have also tried in another field type file, with same results.

If someone can give me a heads up, what am I doing wrong or what is missing. I can’t find any explanatory documentation on line.

Thank you.
