This is particularly useful in finding a `sender_account_id` when [subscribing a contact to a sequence](https://developer.close.com/api/resources/sequences/create-subscription) Additionally, we have also added a clarification to the [Fields](/api/overview/fields) section regarding the use of response fields in integrations. Non-custom fields that are returned by an endpoint that are not listed in our sample response should not be used in integrations, as they may change without warning.
