API Stability Long-Term

The assignParserToIngestTokenV2() GraphQL mutation is used to assign an ingest token to be associated with a parser. To unassign a parser, though, use the unassignIngestToken() mutation.

To assign a parser to an ingest token using instead the LogScale API, see the Assign a Parser to a Token section of the Ingest Tokens documentation page.

Syntax

Below is the syntax for the assignParserToIngestTokenV2() mutation field:

graphql
assignParserToIngestTokenV2(
       input: AssignParserToIngestTokenInputV2!
    ): IngestToken!

Below is an example of how this mutation field might be used:

Raw
graphql
mutation {
	assignParserToIngestTokenV2( input:
	  { repositoryName: "humio",
      tokenName: "my-token",
      parser: "kv"
    } )
  { name }
}
Mac OS or Linux (curl)
shell
curl -v -X POST $YOUR_LOGSCALE_URL/graphql \
    -H "Authorization: Bearer $TOKEN" \
    -H "Content-Type: application/json" \
    -d @- << EOF
{"query" : "mutation {
	assignParserToIngestTokenV2( input:
	  { repositoryName: \"humio\",
      tokenName: \"my-token\",
      parser: \"kv\"
    } )
  { name }
}"
}
EOF
Mac OS or Linux (curl) One-line

      tokenName: \"my-token\",
      parser: \"kv\"
    } )
  { name }
}"
}
EOF
Windows Cmd and curl
