# Delete field

`DELETE /v1/userfields/tasks/:id`

Bitrix24 method: `task.item.userfield.delete`. Scope: `task`.

**Field values disappear from every task in the account with no recovery.**

Deletes the field schema, enumeration variants and stored values. Recreating the same field name does not restore values. The field is read before deletion. System fields are protected: `403 SYSTEM_FIELD_PROTECTED`. Response: `204` with no body. A repeated delete returns `404 ENTITY_NOT_FOUND`.

## Errors and access

Missing scope: `403 SCOPE_DENIED`. Portal plan without TASK_CUSTOM_FIELDS: `403 TASK_CUSTOM_FIELDS_UNAVAILABLE`, including reads. Nonexistent fields: `404 ENTITY_NOT_FOUND`. Invalid input: `400`; Bitrix24 business refusals: `422`. Bitrix24 write permission refusals: `403`. Reads accept READONLY keys; writes require READWRITE and portal administrator rights. Writes are never retried automatically. After a timeout, the outcome is unknown: reread the field before another write.
