Enable tax collection on a zoho books connection

Register Zoho Books webhooks (create/edit per entity, plus invoice delete) and five invoice/credit-note workflows (if needed) and enable tax calculation (L2) on a Zoho Books connection. Unlike the generic enable-tax-collection action, this is required before a Zoho Books connection can enable tax collection at all. Returns 400 if the connection is not ready for tax calculation. Returns 404 if the connection does not exist, is not a Zoho Books connection, or belongs to an organization your credential cannot access. A multi-org credential must send an `Organization-Id`, `Connection-Id` or `Entity-Id` selector, or gets a 400. Returns 503 if registering the webhook or workflows fails; retrying may succeed. The optional body takes `viaL2Checklist` and `requestId`.

Category: Connections

Path parameters:
conn_id (string, required) - The unique identifier of the connection.

Request body:
viaL2Checklist (boolean) - When true, check the connection's readiness from live data and save the result, instead of requiring saved readiness. Defaults to false.
requestId (string) - Optional client-generated id for this attempt (a UUID or a short slug), stored on the audit trail so a later read can tell repeated attempts apart.

Response fields:
id (string, required) - Kintsugi's unique identifier for the connection.
organizationId (string, required) - Id of the organization this connection belongs to.
platformEntityId (string) - The platform's own identifier for the entity this connection points at (e.g. a QuickBooks realm id, D365 company id, NetSuite subsidiary id). Use it to resolve a connection from an id you already hold. `null` until captured on (re)connect or backfilled.
externalId (string, required) - The connection's own external identifier: an Apideck consumer id for a Vault-backed source, or the platform-specific value the connector stores (e.g. a Shopify shop id, a Stripe publishable key).
source (string, required) - Origin platform of the connection (e.g. SHOPIFY, QUICKBOOKS). Any origin outside the published values is reported as OTHER.
