## API gotchas

* Emarsys offers different APIs(Emarsys core, Loyalty V4 and SMS), currently Nango support Emarsys core API which offers WSSE over SSL authentication.
* When creating a new connection in Nango, use a combination of the `username` and `secret` that you received during onboarding. The `username` follows the format `account_name00X`, where X is a digit.
* The OAuth Token has a fetch rate limiting of per `client_id`: 2 requests per minute, 10 requests per hour or per `customer_id`: 10,000 requests per day.
