Troubleshooting & FAQ

For common questions between Single-seller and Multi-seller documentation, refer to the shared documentation.

Campaigns

1. What is a Single-Seller campaign and how is it created?

A Single-Seller campaign (identified by sellerCampaignId) is a per-seller campaign derived from a template campaign configured by Criteo. You do not create it directly via the API. Instead, Criteo automatically creates the campaign when the first valid budget is submitted for a (sellerId, templateCampaignId).After the first budget is accepted, allow for a short asynchronous provisioning delay before impressions begin.

2. What is the template campaign and how do I get one?

A template campaign is a non-delivering campaign configuration managed by Criteo. It acts as the blueprint used to generate Single-Seller campaigns.The template defines settings such as:

optimization goal
bidding strategy
audiences
creatives
delivery configuration

Template campaigns cannot be created via the API.

3. Where do I get the template campaign ID?

The templateCampaignId is provided to you directly by Criteo when your Single-Seller template is configured. It is not retrievable via a self-serve API endpoint.

4. What is the difference between a campaign, a template campaign, and a seller-campaign?

Entity	Who creates it	What it does
Campaign	Criteo	Top-level ad configuration; not managed via MPO API
Template campaign (`templateCampaignId`)	Criteo	Single-Seller blueprint; defines shared settings for all derived seller-campaigns
Seller-campaign (`sellerCampaignId`)	Created implicitly by Criteo on first budget`POST`	Per-seller delivery campaign; managed via budgets and`productSet`

5. How do I pause or resume a Single-Seller campaign?

You do not pause seller-campaigns directly. Instead, suspend or resume the associated budget.Pause:

HTTP

PATCH /marketplace-performance-outcomes/budgets
{ "budgetId": "789", "isSuspended": true }

Resume:

HTTP

PATCH /marketplace-performance-outcomes/budgets
{ "budgetId": "789", "isSuspended": false }

If the budget’s endDate is in the past, resuming will not restart delivery. Create a new budget with a future period instead.

6. Why is my seller-campaign not delivering even though it looks active?

Check the suspendedSince and suspensionReasons fields on the seller-campaign. If suspendedSince is null and suspensionReasons is null, the campaign appears active to the API but may still not be delivering. Check that the template campaign is active and the budget meets the minimum per-seller threshold.If suspensionReasons contains a value, refer to the table below:

Reason	Meaning	Action
`ManuallyStopped`	Budget manually suspended	Resume via budget`PATCH`
`NoBudgetDefined`	No active budget exists	Create a valid budget
`NoMoreBudget`	Budget fully spent	Create a new budget for a future period
`RemovedFromCatalog`	All products removed	Restore products in the catalog
`NotYetStarted`	Newly created, not yet processed	Wait for provisioning
`NoMoreDailyBudget`	Daily spend limit reached	No action needed; resets the next day
`Other`	Internal error	Contact Criteo Product or R&D

7. What does the `Other` suspension reason mean?

Other indicates that an internal issue is preventing the campaign from delivering, for example, a click spike prevention mechanism. This is not a client-side configuration error and cannot be resolved through API calls alone. Surface this to your operations team and notify your Criteo Product or R&D contact for investigation.

8. Can I configure which products a seller-campaign advertises?

Yes. Use the productSet feature to attach a whitelist of product IDs (by ExternalItemId) to a seller-campaign:

PATCH /marketplace-performance-outcomes/seller-campaigns
[{
  "id": "SELLER_123.TEMPLATE_CAMPAIGN_456",
  "productSet": {
    "value": [{ "operator": "IsIn", "field": "ExternalItemId", "values": ["SKU_1", "SKU_2"] }]
  }
}]

Notes:

productSet is optional; without one, all eligible products from the seller’s catalog are used.
A minimum number of product IDs is required per productSet (default: 20). Providing fewer will return a 4xx error.
productSet is only supported on Single-Seller campaigns. It cannot be used on multi-seller campaigns.
To remove the productSet and revert to all eligible products, set productSet.value to null.

Budgets

9. What budget types are available in Single-Seller?

Only capped total budgets over a fixed date range are supported. Daily and uncapped budget types are not available in Single-Seller mode.If your use case requires always-on or short-duration delivery, the following patterns are supported as workarounds:Always-on delivery
Schedule a sequence of consecutive, non-overlapping capped budgets — for example, monthly budgets submitted in advance. Each budget covers a fixed period and the next begins where the previous ends.Short-duration budgets
Submit individual capped budgets for the desired interval (daily, weekly, or monthly). Each must be a separate non-overlapping request for the same (sellerId, templateCampaignId) pair.

10. How does pacing work?

Daily pacing is automatic. The system distributes the total budget evenly across the budget period, computing a daily target. Under-delivery or over-delivery on a given day is compensated across the remaining days, as long as the budget period is active.

11. How do I check the remaining budget?

There is no dedicated endpoint for remaining budget. Calculate it using:

remaining budget = amount − spend

Both amount and spend are available from:

GET /marketplace-performance-outcomes/budgets
GET /marketplace-performance-outcomes/budgets/{budgetId}

12. Can budget periods overlap for the same seller?

No. For a given (sellerId, templateCampaignId) pair, budget periods must not overlap. Suspended budgets are treated as logically canceled and do not block new budgets for the same dates.

13. Can I schedule future budgets?

Yes. You can create budgets with future startDate values as long as their date ranges do not overlap with any existing active budgets for the same (sellerId, templateCampaignId) pair.

14. How do I calculate the minimum budget amount for a request?

The minimum budget amount for a given period is:

minimum amount = minimum daily budget per seller (provided by Criteo) × number of days in the period

If the amount is below this threshold, the API will return a 4xx error.

Statistics

15. Which stats endpoints do I use for Single-Seller?

Single-Seller performance uses the same stats APIs as multi-seller. Choose the endpoint based on the granularity you need:

Endpoint	Use case
`GET /marketplace-performance-outcomes/stats/campaigns`	Aggregated across all sellers for a template
`GET /marketplace-performance-outcomes/stats/sellers`	Per-seller aggregation
`GET /marketplace-performance-outcomes/stats/seller-campaigns`	Per seller-campaign (most granular)

16. Are statistics available in local time zones?

Statistics data defaults to UTC. However, a timezone parameter is available in the Stats API request to retrieve data in a specific time zone.

17. What is the data latency for statistics?

Statistics are typically available with a latency of a few hours. Refer to the Getting Statistics page for current SLA guidance.

18. I just created a seller's first budget but I'm seeing no impressions. What's wrong?

This is expected immediately after the first budget creation. Criteo creates the underlying seller-campaign synchronously when the first budget is accepted, but there is a short asynchronous provisioning delay before delivery begins.If impressions do not appear after a reasonable wait, check:

The template campaign is active (not paused or archived).
The budget amount meets the minimum per-seller threshold.
The budget isSuspended is false.
The seller has eligible products in the catalog (no RemovedFromCatalog suspension reason).
If a productSet is configured, the product IDs are valid and active in the seller’s catalog.
