Authorizations

Authorization
string
header
required

Access token issued by the CDF project's configured identity provider. Access token must be an OpenID Connect token, and the project must be configured to accept OpenID Connect tokens. Use a header key of 'Authorization' with a value of 'Bearer $accesstoken'. The token can be obtained through any flow supported by the identity provider.

Path Parameters

functionId
integer
required

The function id.

Body

application/json
nonce
string
required

Nonce retrieved from sessions API when creating a session. This will be used to bind the session before executing the function. The corresponding access token will be passed to the function and used to instantiate the client of the handle() function. You can create a session via the Sessions API. When using the Python SDK, the session will be created behind the scenes when creating the schedule.

data
object

Input data to the function (only present if provided on the schedule). This data is passed deserialized into the function through one of the arguments called data. WARNING: Secrets or other confidential information should not be passed via the data object. There is a dedicated secrets object in the request body to "Create functions" for this purpose.'

Example:
{ "timeSeriesId1": 13435351, "maxValue": 4 }
