Authorizations

x-sumvin-pint-token
string
header
required

PINT (Purchase Intent) token — a JWT issued via POST /v0/sis/token/pint that encodes user-level consent for a specific scope. Sent in the x-sumvin-pint-token header alongside or instead of an x-juno-jwt JWT, depending on the integration surface (Platform vs SIS).

Headers

​
x-juno-orgid
string | null

Tenant org ID for multi-tenant auth

x-sumvin-token

X-Timestamp-Format
string

Controls how timestamp fields are serialized in JSON response bodies.

Default (header omitted or any other value): epoch milliseconds as integers. iso8601: UTC ISO 8601 strings of the form YYYY-MM-DDTHH:MM:SSZ.

Example: with X-Timestamp-Format: iso8601, the field value 1704067200000 becomes "2024-01-01T00:00:00Z".

Affected fields (recursively, in dicts and arrays): any field whose name ends in _at, plus the literal field names timestamp, period_start, and period_end. All other fields are passed through unchanged.

Only iso8601 is recognized. Any other value (or omitting the header) yields the default epoch-ms representation; the server does not reject unknown values, so this is documented as an example rather than an enum to keep generated clients permissive.

Example:

"iso8601"
