Send conversion events to an ad platform
Relay one or more conversion events to the target ad platform's native Conversions API. Platform is inferred from the provided `accountId`. Requires the Ads add-on. Supported platforms: - Meta (`metaads`) via Graph API - Google Ads (`googleads`) via Data Manager API `ingestEvents` - LinkedIn (`linkedinads`) via `/rest/conversionEvents` `destinationId` semantics differ per platform: - Meta: pixel (dataset) ID, e.g. `123456789012345` - Google: conversion action resource name, e.g. `customers/1234567890/conversionActions/987654321` - LinkedIn: conversion rule ID or URN, e.g. `104012` or `urn:lla:llaPartnerConversion:104012` Callers can list valid destinations via `GET /v1/accounts/{accountId}/conversion-destinations`. All PII (email, phone, names, external IDs) is hashed with SHA-256 server-side per each platform's normalization spec, including Google's Gmail-specific dot/plus-suffix stripping. Send plaintext. LinkedIn `externalIds` are passed through as plaintext per LinkedIn's spec; only emails and phones are hashed. For LinkedIn, the connected account must have been authorized after the Conversions API rollout (i.e. the OAuth grant must include `rw_conversions`). Older accounts must reconnect. Batching is handled automatically. Meta caps at 1000 events per request and rejects the entire batch if any event is malformed. Google caps at 2000. LinkedIn caps at 5000 and is also all-or-nothing per chunk. Dedup: pass a stable `eventId` on every event. Meta and LinkedIn use it to dedupe against browser-side pixel/Insight Tag events; Google maps it to `transactionId`. Per-platform `eventName` semantics: - Meta: free-form. Standard names (Purchase, Lead, ...) match Meta's built-in events; custom strings are accepted. - Google: ignored. The conversion action's category determines the event type. Send the standard name closest to your action for documentation, but the platform will not branch on it. - LinkedIn: ignored. The conversion rule's `type` (LEAD, PURCHASE, etc.) is locked to the destination at rule-creation time. Send the standard name for documentation; LinkedIn does not branch on it.

}Remove campaign↔conversion associations DELETE
Remove one or more campaign associations from this conversion rule. Pass `adAccountId` and `campaignIds` as query parameters (`campaignIds` is comma-separated). The route also accepts a JSON body with the same fields for clients that prefer DELETE-with-body, but the documented surface is query-only because some SDK code generators (e.g. Python) collapse query + body parameters with the same name into a single kwarg.
Send WhatsApp conversion event POST
Forward a WhatsApp Business Messaging conversion event (`LeadSubmitted`, `Purchase`, `AddToCart`, `InitiateCheckout`, `ViewContent`) to Meta's Conversions API with `action_source = business_messaging` and `messaging_channel = whatsapp`. The endpoint looks up the originating CTWA click ID (`ctwa_clid`) captured on the first inbound message of the conversation and replays it on every event so Meta can attribute the conversion back to the Click-to-WhatsApp ad that drove the chat. Configuration prerequisites on the WhatsApp account metadata: - `metaCapiDatasetId`: the Meta Pixel/Dataset ID linked to the WABA. - `connectedFacebookPageId`: the Facebook Page paired with the WhatsApp Business number. Identify the conversation by either `conversationId` (preferred) or `phoneE164` (digits only, no `+`). At least one is required. If the conversation has no captured `ctwa_clid`, the request returns 422 because there is nothing to attribute. Token and dataset coupling: the WhatsApp account's accessToken must have access to the configured `metaCapiDatasetId`. By default a WABA's system-user token is scoped to the WABA's own Business Manager and cannot post to a pixel owned by a different Business; Meta returns code 100 in that case. Either share the dataset with the WhatsApp app's Business in BM, or use a dataset already in the same Business as the WABA.
