Starting on September 1, 2020, we will be making a change to how the Google Ads API reports campaign-level bid modifiers to make the API’s results more consistent with the Google Ads UI.

Currently, Google Ads Query Language queries for campaign_bid_modifier resources only return rows if either of the following conditions are met:

1. A non-zero bid modifier is set, or
2. The row’s associated criterion_id has accrued metrics for the CALLS interaction type.

After this change goes into effect, queries for campaign_bid_modifier resources will return rows for all campaigns, more closely matching what a user sees in the Google Ads UI’s Advanced bid adj. > Interactions screen.

Users who wish to keep using a restricted view of their campaign_bid_modifier reports can add a predicate such as “WHERE campaign_bid_modifier.bid_modifier != 1.0" (where a 1.0 value is equivalent to a bid adjustment of ±0%) to their queries to limit reporting to non-zero bid modifier rows.

This change will not affect the behavior of the AdWords API.

If you have any questions about this change, please reach out to us on the forum.

On July 14th, 2020, we will begin enforcing stricter validation for requests to the DCM/DFA Reporting and Trafficking API. This change will initially be introduced for 5% of API traffic during the week of July 14, 10% the week of July 21, 30% the week of July 28, and all requests by August 7th, 2020. 

As a result, your requests might begin returning additional errors. Please update your requests, as needed. 

The following list includes the error codes that you might see, as well as the recommended solutions:

• "Invalid value - Enum" - Ensure you are using valid enum values. For more information, see the API Reference.
• "Invalid value - Bool" - Ensure boolean fields in the request are set to true/false, rather than empty string.
• "Invalid value - Integer ####.0" - Ensure integer fields in the request are set to valid integers.
• "Invalid JSON Payload - NaN" - Ensure NaN does not appear in the request payload.
• "Invalid JSON payload received. - not repeating" - Do not use arrays for non-array fields.

Method specific errors:

• dfareporting.reports.run: "Invalid JSON payload received. Unexpected end of string. Expected a value" - Ensure the request body is completely empty.
• dfareporting.reports.list: "Request contains an invalid argument." - Ensure that empty fields in the response contain a valid value. For example, empty array fields must be specified by an empty array, rather than an empty string or object.
• dfareporting.files.get and dfareporting.reports.files.get: "OAuth token was passed in the query parameter. Please send it in Authorization header instead." - Requests must use the HTTP header Authorization: Bearer [ACCESS_TOKEN] to pass OAuth credentials.

Why is this changing?
Stricter validation helps ensure that problematic requests are not silently ignored, and aligns the behavior of the DCM API with that of other Google APIs.
