# headers

This block is part of the [`http connection`](https://docs.rual.nl/block-types/http%20connection) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

Returns all headers known to us in the HTTP request.

- connection required `httpconnection`

- headers `object`

Outputs all request headers as an object keyed by header name. When the connection pin is unwired it falls back to the connection of the currently running function; emits nil when no headers exist.

A typical wiring for [headers](https://docs.rual.nl/block-types/http%2520connection/httpconnection_get_headers): [current request](https://docs.rual.nl/block-types/http%2520connection/httpconnection_current_request) feeds the `connection` pin; the `headers` out pin feeds [custom field](https://docs.rual.nl/block-types/object/object_get_custom_field).

## Commonly used with

In production blueprints, this block is most often wired together with:

- [log](https://docs.rual.nl/block-types/logging/function_console_log): this block feeds into it.

- [current request](https://docs.rual.nl/block-types/http%20connection/httpconnection_current_request): feeds into this block. Retrieves a reference to the current HTTP Connection.

- [custom field](https://docs.rual.nl/block-types/object/object_get_custom_field): this block feeds into it. get the value of a custom field with a custom value block, or dynamic value.

- [new object](https://docs.rual.nl/block-types/object/object_new_fields): this block feeds into it. Builds a new object filled with the given fields.
