Launch

PATCH API Enhancements for Campaign Management

Availability: Sandbox and Production

PATCH support is now available across Display Campaign Management APIs, enabling partial updates to campaigns and related entities.

Previously, updates required full object replacement via PUT, increasing payload size and risk of unintended overwrites. PATCH allows you to update only the fields that have changed

Endpoints

Key capabilities

Partial updates: Only provided fields are updated; omitted fields remain unchanged
Batch support: Multiple entities can be updated per request
Field-level control: Supports granular updates across budgets, bids, and targeting.
Consistent validation: Existing business rules from PUT APIs remain enforced

Recommended usage

Use PATCH for:

Bid and budget adjustments
Targeting updates

Continue using PUT for:

Full object replacements

Backward compatibility

No breaking changes
Existing PUT endpoints remain supported

Update

Moderation Assist (beta)*

To align with the updated Walmart Connect Advertising Policies, we are making corresponding updates to the Moderation Assist API (beta).

As part of this transition, the prohibited_Contents response within the Moderation Assist API results endpoint will be temporarily paused while we implement, retrain, and validate models against the updated policy requirements. During this period, prohibited_Contents will return an empty array, but the following response fields will remain available for use:

acknowledgementClaims
substantiationClaims
