FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.

Delete a token

Problem

You need to delete a token from the current database.

Solution

Use the function:Delete[] function:

client.query(
  q.Delete(q.Ref(q.Tokens(), '1'))
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))

{
  ref: Ref(Tokens(), "1"),
  ts: 1631739422930000,
  instance: Ref(Collection("users"), "1"),
  hashed_secret: '$2a$05$HgbE0YEse2i7.5F4a5MHm.wGDmk4C3kMrP7NJpP40GrO06DgP584q',
  data: { team: 'Marketing' }
}

result = client.query(
  q.delete(q.ref(q.tokens(), "1"))
)
print(result)

{'ref': Ref(id=1, collection=Ref(id=tokens)), 'ts': 1631739701090000, 'instance': Ref(id=1, collection=Ref(id=users, collection=Ref(id=collections))), 'hashed_secret': '$2a$05$HExlDNKKmJP69pnpzVmf1.nsTDOJ5FbgfwUv9z1CXg./nQBsT70ny', 'data': {'team': 'Marketing'}}

result, err := client.Query(
	f.Delete(f.Ref(f.Tokens(), "1")))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}

map[data:map[team:Marketing] hashed_secret:$2a$05$a77WPbm2U.Ms6GSw6oNp5uOZMefME5e.hLQxIhsgh/h2ceKQpxS8W instance:{1 0xc000109a10 0xc000109a10 <nil>} ref:{1 0xc000109860 0xc000109860 <nil>} ts:1631739856660000]

try
{
    Value result = await client.Query(
        Delete(Ref(Tokens(), "1"))
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}

ObjectV(ref: RefV(id = "1", collection = RefV(id = "tokens")),ts: LongV(1631740130800000),instance: RefV(id = "1", collection = RefV(id = "users", collection = RefV(id = "collections"))),hashed_secret: StringV($2a$05$ido9qqXfQ.KjpZQLfGqYJup/kilkj9Vqka3Yuzx//oPpjsJw69QHO),data: ObjectV(team: StringV(Marketing)))

System.out.println(
    client.query(
        Delete(Ref(Tokens(), "1"))
    ).get());

{ref: ref(id = "1", collection = ref(id = "tokens")), ts: 1631740302150000, instance: ref(id = "1", collection = ref(id = "users", collection = ref(id = "collections"))), hashed_secret: "$2a$05$iJNG63lEeIwJum933SCCee/lqssvYlETxzVOiUeWK/BiLazjGsbgC", data: {team: "Marketing"}}

Delete(Ref(Tokens(), '1'))

  ref: Ref(Tokens(), "1"),

Discussion

Once a key has been deleted, any client still using the key’s secret can no longer execute queries.
