This is a dry-run endpoint that returns what each advertiser's field would change to, any validation errors, and the current value of each field. Use this to validate changes before calling the apply endpoint. The response includes a `changes` array showing the before/after for each advertiser, and a `resource_errors` array for any IDs that could not be processed. Each field to change requires a `field_type`, a `field_value` (whose type depends on the field), and an `operator` that controls how the value is applied. ## OpenAPI ````yaml openapi/advertisers-extras.yaml post /networks/patch/advertiser/submit openapi: 3.0.3 info: title: Everflow Network API - Advertisers (Additional Endpoints) description: > Additional advertiser endpoints for the Everflow partner marketing platform, including the patch preview/submit endpoint. version: 1.0.0 servers: - description: Production Server url: https://api.eflow.team/v1 security: [] tags: - name: Advertisers description: Additional advertiser management endpoints. paths: /networks/patch/advertiser/submit: post: tags: - Advertisers summary: Advertiser Bulk Edit Preview requestBody: required: true content: application/json: example: network_advertiser_ids: - 13 fields: - field_type: advertiser_status field_value: active operator: overwrite schema: type: object required: - network_advertiser_ids - fields properties: network_advertiser_ids: type: array description: Array of advertiser IDs to preview changes for. items: type: integer fields: type: array description: > Array of field changes to preview.
