}Provision CTWA conversions dataset POST
Creates (or fetches, if one already exists) the Meta dataset that Click-to-WhatsApp ad events are reported against via the Conversions API, and persists its ID on the account as `metadata.metaCapiDatasetId`. The call is GET-first idempotent — a WABA can only own one CTWA dataset, so a second call after a successful provision is a safe no-op that returns the same ID with `created: false`. Requires the connected WhatsApp account's token to carry the `whatsapp_business_manage_events` permission. If the permission is missing the endpoint returns 422 with a message asking the user to reconnect the account.
Get CTWA conversions dataset GET
Returns the Meta Click-to-WhatsApp conversions dataset currently linked to the WhatsApp account, if one has been provisioned. Reads only from the stored `metadata.metaCapiDatasetId` — never hits Meta, never creates a dataset. Use this to detect whether `POST /v1/whatsapp/conversions` is configured for an account.
