POST https://um-catlab.zulipchat.com/api/v1/messages/{message_id}/reactions
Add an emoji reaction to a message.
Usage examples
#!/usr/bin/env python3
import zulip
# Pass the path to your zuliprc file here.
client = zulip.Client(config_file="~/zuliprc")
# Add an emoji reaction.
request = {
"message_id": message_id,
"emoji_name": "octopus",
}
result = client.add_reaction(request)
print(result)
curl -sSX POST https://um-catlab.zulipchat.com/api/v1/messages/43/reactions \
-u BOT_EMAIL_ADDRESS:BOT_API_KEY \
--data-urlencode emoji_name=octopus
Parameters
message_id integer required in path
Example: 43
emoji_name string required
Example: "octopus"
The target emoji's human-readable name.
To find an emoji's name, hover over a message to reveal
three icons on the right, then click the smiley face icon.
Images of available reaction emojis appear. Hover over the
emoji you want, and note that emoji's text name.
emoji_code string optional
Example: "1f419"
A unique identifier, defining the specific emoji codepoint requested,
within the namespace of the reaction_type.
For most API clients, you won't need this, but it's important
for Zulip apps to handle rare corner cases when
adding/removing votes on an emoji reaction added previously by
another user.
If the existing reaction was added when the Zulip server was
using a previous version of the emoji data mapping between
Unicode codepoints and human-readable names, sending the
emoji_code in the data for the original reaction allows the
Zulip server to correctly interpret your upvote as an upvote
rather than a reaction with a "different" emoji.
reaction_type string optional
Example: "unicode_emoji"
A string indicating the type of emoji. Each emoji reaction_type
has an independent namespace for values of emoji_code.
If an API client is adding/removing a vote on an existing reaction,
it should pass this parameter using the value the server provided
for the existing reaction for specificity. Supported values:
-
unicode_emoji : In this namespace, emoji_code will be a
dash-separated hex encoding of the sequence of Unicode codepoints
that define this emoji in the Unicode specification.
-
realm_emoji : In this namespace, emoji_code will be the ID of
the uploaded custom emoji.
-
zulip_extra_emoji : These are special emoji included with Zulip.
In this namespace, emoji_code will be the name of the emoji (e.g.
"zulip").
Changes: In Zulip 3.0 (feature level 2), this parameter became
optional for custom emoji;
previously, this endpoint assumed unicode_emoji if this
parameter was not specified.
Response
Example response(s)
Changes: As of Zulip 7.0 (feature level 167), if any
parameters sent in the request are not supported by this
endpoint, a successful JSON response will include an
ignored_parameters_unsupported array.
A typical successful JSON response may look like:
{
"msg": "",
"result": "success"
}
An example JSON error response for when the emoji code is invalid:
{
"code": "BAD_REQUEST",
"msg": "Invalid emoji code",
"result": "error"
}
An example JSON error response for when the reaction already exists.
Changes: New in Zulip 8.0 (feature level 193). Previously, this
error returned the "BAD_REQUEST" code.
{
"code": "REACTION_ALREADY_EXISTS",
"msg": "Reaction already exists.",
"result": "error"
}
