Create statement

Stores and indexes the uploaded statement, optionally under a graph, and can issue a verifiable credential for it, stored the same way. With graph_id the caller needs create_declarations on the graph's project; without it, in at least one project.

Request bodyrequired

The statement JSON must provide an @id field unless generate_id is set to true. If generate_id is true, the service computes the statement CID and inserts it as statement.@id. If omitted or false, the submitted statement must already include a matching @id field.

application/json

generate_idboolean | null
If true, the service computes the statement CID and inserts it as statement.@id. If omitted or false, the submitted statement must already include a matching @id field.
graph_idstring | null
The uuid of the graph to register the statement under. This is the uuid used to retrieve this statement as part of a larger graph.
issue_vcboolean | null
Set to true to create a verifiable credential for the statement.
statementobjectrequired
Integrity statement JSON. Provide an @id field unless generate_id is set to true.
