POST /connections/maxio/connect

Connect a maxio account

Create or update a Maxio connection with an API key and subdomain. Re-submitting the same `subdomain` updates its stored key rather than creating a second connection. Returns 400 if the credentials are invalid. A multi-org credential must send an `Organization-Id`, `Connection-Id` or `Entity-Id` selector, or gets a 400.

Category: Connections

Request body:
apiKey (string, required) - Maxio API key.
subdomain (string, required) - Maxio account subdomain.
historicalSyncStartDate (string) - Import floor for a brand-new connection, as YYYY-MM-DD. Ignored on reconnect. `null` applies the default seven-year lookback.

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).

  allowed values: ACUMATICA, AIRWALLEX, AMAZON, API, APPLE_APP_STORE, BESTBUY, BIGCOMMERCE, BILL_COM, BUNNY, CAMPFIRE, CHARGEBEE, CHECKOUTCHAMP (and 58 more, see the reference page)

  allowed values: ACTIVE, INACTIVE, CONNECTION_ERROR
storeName (string) - Human-readable store or account name for the connection; an empty string when the connection has none.
url (string) - Public shop/account URL when the source exposes one; not a secret.
createdAt (string, required) - When the connection was created.
updatedAt (string) - When the connection was last updated.
lastSynced (string) - When this connection last completed a successful sync.
