# Find your module and field names

## Find the module table name

In the Designer, look at the module card. Its table name sits under the module name. Send that table name as `module`, for example `cm_equipment_requests_base`.

The display name isn't the table name. If a call returns `MODULE_NOT_FOUND`, copy the table name again.

## Find field System names

Open Designer → module → Fields. Copy the field's **System name**. Use these names in `data`, `fields`, `filters` and `sort`. For example, a field may use `needed_by`.

Unknown field names in write `data` are ignored. If no fields match, the API returns `INVALID_DATA`. An invalid filter field returns `INVALID_FILTER`; if no sort field is valid, the API returns `INVALID_SORT`.

## Find a record id

The record's `id` is an integer: the value of the module's key field. Query and get return `id`; keep it for update, delete and file downloads.

## Hand the names to your assistant

To hand these names to an AI assistant, paste them into [Brief your AI assistant](/developers/api/build-with-ai/), with field types if you have them. Don't include an API key.
