Get Event Match Quality
Reads Meta Event Match Quality (EMQ) and pixel↔CAPI event coverage for a pixel/dataset, live from Meta's Dataset Quality API. Web events only (a Meta limitation). Meta-only; other platforms return 405. Requires the Ads add-on.

}Adjust uploaded conversions POST
Adjust conversions that were previously uploaded via `POST /v1/ads/conversions` — retract them, restate their value, or enhance them with first-party data. Requires the Ads add-on. **Google Ads only.** Google handles adjustments through the classic Google Ads API (`ConversionAdjustmentUploadService`); the Data Manager `ingestEvents` path used for sending conversions is ingest-only. Meta and LinkedIn have no equivalent, so this endpoint returns `405` for those platforms. Adjustment types: - `RETRACTION` — remove the conversion entirely (refund, chargeback, cancelled order, churn). - `RESTATEMENT` — change the conversion's value (upgrade / downgrade / partial refund). Send the corrected **total** value in `restatementValue` (not a delta). - `ENHANCEMENT` — attach first-party identifiers (hashed email / phone) to an existing conversion (enhanced conversions applied after the fact). Identifying the original conversion (per adjustment): - `orderId` — the transaction ID you sent as `eventId` on the original conversion. Recommended, and **required** for `ENHANCEMENT`. - or `gclid` + `conversionTime` — the click ID and the original conversion's time (unix seconds). Not available for `ENHANCEMENT`. `destinationId` is the conversion action resource name, e.g. `customers/1234567890/conversionActions/987654321` (same value you send to `POST /v1/ads/conversions`). PII in `user` is hashed with SHA-256 server-side (Gmail-specific normalization included). Send plaintext. Times are unix seconds; we convert to Google's required `yyyy-MM-dd HH:mm:ss+00:00` format. Up to 2000 adjustments per request; partial failure is supported (inspect `adjustmentsFailed` / `failures[]`).
List conversion events GET
Returns the most recent conversion events sent through `POST /v1/whatsapp/conversions` for the given WhatsApp account. Sourced from delivery logs (Axiom `late` dataset), so the visible window is bounded by log retention (about 30 days). Useful for rendering a "recent activity" panel on the conversions setup tab without standing up a parallel persistence layer. Per-event payload mirrors the structured log we write on every successful send: `eventName`, `conversationId`, `eventsReceived`, `eventsFailed`, `traceId`, `durationMs`, and the wall-clock `timestamp`.
