Overview
When updating a campaign, fields that are omitted from the request (or have a value of null) remain unchanged. This is useful, as you can update certain fields in the campaign, without submitting the entire field set.
However, certain campaign fields - e.g. publisher_bid_modifier - store a collection of values. You might want to update specific elements within that collection - without submitting the entire collection for that field. The PATCH request addresses this need - it allows you to submit partial updates within a given field.
Supported Fields
Currently, the PATCH operation is supported by the following campaign fields only:
PATCH Operations
In general, the following operations are available for a PATCH request:
| Operation | Description |
|---|---|
| ADD | Add a new item to the collection. |
| REPLACE | Replace an existing item in the collection. You cannot run the ADD operation twice for a given item - you must use REPLACE. Not all collections support REPLACE. |
| REMOVE | Remove an existing item from the collection. |
Not all collections support the REPLACE operation.
Taboola Backstage UI
After patching a collection via the API, there may be a delay before the Taboola Backstage UI displays the change.
