Resumes a READY AD_STRUCTURE_CREATE draft from persisted server state. This call may query Amazon Ads for keyword or ASIN candidates and suggested bids, including candidates not yet created in the account, or reuse saved recommendations. It persists workflow progress and decisions. It reconciles the last atomic plan, retains successful Amazon IDs, and prepares exactly the next Campaign, Ad Group, Product Ad, automatic-target bid, or Targeting plan. All Campaigns are prepared together, then all Ad Groups, then all Product Ads across every ad group in one multi-group plan; the Product Ad plan is completed before any targeting recommendation or bid decision can pause another structure. It never confirms or applies a write plan. For AUTO ad groups it persists the selected bid mode with the created adGroupId, synchronizes the four Amazon-created targets, obtains suggested bids when selected, and returns a separately confirmable AD_TARGETING_CHANGE plan. Partial writes retry only failed items. A 429 suggestion read includes per-target evidence; ambiguous create results require reconciliation and are never retried. For MANUAL ad groups without supplied positive targeting, it waits until Product Ads exist, persists Amazon candidates only for the recorded KEYWORD or ASIN TARGET family, accepts customer selection by candidateRef, obtains suggested or custom bids, accepts explicit customCandidates when recommendations are absent or rejected, and prepares separately confirmable Targeting plans. It accepts at most 100 selected candidates per ad group and reuses the exact suggested bids already shown to the customer. Once every manual decision is ready, it combines all MANUAL positive targeting groups into one batch plan, then combines all configured negative targeting across AUTO and MANUAL groups into one separate batch plan. AUTO-only drafts skip MANUAL processing and MANUAL-only drafts skip AUTO processing. When a plan is returned, pass applyContinuation unchanged to the matching operation-specific execution tool so a successful write automatically returns the next stage preview without asking the customer to advance. After an AUTO bid write, immediately present the returned MANUAL targeting preview or selection action in the same response when manual groups remain.
