# Upload a custom emoji

{generate_api_description(/realm/emoji/{emoji_name}:post)}

## Usage examples

{start_tabs}

{tab|python}

{generate_code_example(python)|/realm/emoji/{emoji_name}:post|example}

{tab|curl}

{generate_code_example(curl)|/realm/emoji/{emoji_name}:post|example}

{end_tabs}


## Arguments

As described above, the image file to upload must be provided in the
request's body.

## Emoji name

The emoji name can only contain letters, numbers, dashes, and spaces.
Upper and lower case letters are treated the same, and underscores (_)
are treated the same as spaces (consistent with how the Zulip UI
handles emoji).

## Maximum file size

The maximum file size for uploads can be configured by the
administrator of the Zulip server by setting `MAX_EMOJI_FILE_SIZE`
in the [server's settings][1]. `MAX_EMOJI_FILE_SIZE` defaults
to 5MB.
