INVALID_FIELD_NAME Error For requesting Multiple Selector Fields in CampaignService

[Jagadish B]

I'm trying to send XML based Adwords API request to CampaignService.

As per the API documentation for the CampaignService  we can pass on multiple selector fields in the XML request. But I don't understand the format in which these fields should be passed on ..

I have tried the following formats for requesting Campaign Id and Campaign Name selector fields, but it is giving me INVALID_FIELD_NAME error.

Formats tried :  'Id','Name'  ;  [Id,Name]  ; ['Id','Name']  ----  All raising same error.

both Id and Name are valid fields for the CampaignService.

Can any help me with what should be the format in which these selector formats should be passed on?

I attach the XML request body and Error below

Much appreciate your help on this.

Okay,  I think each field need to be in a separate line of code all together.

  <v201:fields>Id</v201:fields>

  <v201:fields>Name</v201:fields>

Hello,

You will need a separate line for each field. You can find an example of what the SOAP request should look like here.
