**REQUEST BODY**

:::BlockQuote
\{
    "session\_sponsor": \{
        "sponsor\_id": \{\{sponsor\_id}},
        "timeslot\_id": \{\{timeslot\_id}},
        "label": "\{\{label\_name}}"
    } 
}
:::

**Required attributes:**

- `sponsor_id` Number / the unique identifier generated by Brella for the sponsors (can be retrieved via the sponsors endpoints) 
- `timeslot_id` Number / the unique identifier generated by Brella for the timeslot (can be retrieved via the timeslot endpoints)
- `label` String / see notes for supported values

**Notes:**

**01:** Both the sponsor and timeslot need to exist in the event. This endpoint can't create these entities for you.

**02:** The `label` attribute can be passed with any strings and will be displayed under the Schedule -> Sponsors -> Sponsors.

**03: **There is duplicate validation in this endpoint. It will not create duplicates in the following situation: The provided \{sponsorId} and \{timeslotId} combination are the same as an existing speaker assignment.
