Notifications

REST API /

All available operations for sending and manipulating notifications

List all notifications #

This endpoint returns information about all of the notifications that a specific user has received.

HTTP Request #

GET https://api.cord.com/v1/users/<USER_ID>/notifications
Copy

Request Body #

This REST endpoint has no request body.

Request Parameters #

The endpoint accepts an optional filter query request parameter. Use this to filter notifications based on their properties.

filter
optional
NotificationListFilter
Notifications will be matched against the filters specified. Please note that because this is a query parameter in a REST API, this JSON object must be URI encoded before being sent.

This is an object with the following fields:

metadata
optional
EntityMetadata
An arbitrary JSON object specified when the notification is created. The value for a metadata entry should be an object representing the metadata key/value to filter on. For example, to show only notifications with the metadata key of "category" set to "sales", set the filter to { metadata: { category: "sales" } }.
location
optional
Location
The location where the notifications live. This will be the location of the thread containing the message which prompted the notification.
organizationID
optional
string
The organization to which the message that prompted the notification belongs.

Response #

The response is a JSON array of objects with the following fields:

id
string
The ID for this notification.
senderUserIDs
string[]
The IDs of the user(s) who sent this notification. The Cord backend will sometimes aggregate multiple notifications together, causing them to have multiple senders. For example, if multiple people react to the same message, that will generate only one notification (but with multiple senders, one for each person who reacted).
iconUrl
string | null
The URL of an icon image for this notification, if one was specified when it was created. This will always be null for Cord's internally-generated notifications (i.e., it can only be non-null for notifications you create via the REST API).
array
The "header" or "text" of the notification. This will represent text like "Alice replied to your thread." or similar. For notifications you create via the REST API, this will be based upon the template parameter, see below.

This is an array of items. Each item can be one of the following:

  • NotificationTextHeader

    This is an object with the following fields:

    type
    "text"
    Indicator that this is a string header node.
    text
    string
    The text to display. This text may start and/or end with whitespace, which should typically not be trimmed. For example, in order to display the notification "Alice replied to your thread.", this would typically be composed of two nodes -- a user node for Alice, and then a text node containing " replied to your thread.", with a meaningful space at the front, to separate this node from Alice's name.
    bold
    boolean
    Whether the text should be formatted in bold.
  • NotificationUserHeader

    This is an object with the following fields:

    type
    "user"
    Indicator that this is a user reference header node.
    user
    ClientUserData
    The indicated user.

    This is an object with the following fields:

    id
    string
    The user's ID. This is unique within an application.
    name
    string | null
    The user's name.
    shortName
    string | null
    The user's short name. In most cases, Cord components will prefer using this name over name when set.
    profilePictureURL
    string | null
    A URL to the user's profile picture.
    metadata
    EntityMetadata
    Any metadata that has been set for the user.
attachment
Additional context attached to the notification. For example, if this notification is about a new reaction on a message, the attachment will specify what message received that new reaction.
A renderer will typically check the type field of the attachment and render that attachment type below the header.

This property can be one of the following:

  • null
  • NotificationURLAttachment

    This is an object with the following fields:

    type
    "url"
    Indicator that this is a URL attachment.
    url
    string
    The URL this attachment points to. This would typically be the URL to send the browser to if this notification is clicked.
  • NotificationMessageAttachment

    This is an object with the following fields:

    type
    "message"
    Indicator that this is a message attachment.
    message
    CoreMessageData
    The relevant message.

    This is an object with the following fields:

    id
    string
    The ID for the message. If a message is created with no ID, a random UUID-based ID will be automatically created for it.
    authorID
    string
    The ID for the user that sent the message.
    organizationID
    string
    The ID for the organization this message belongs to.
    threadID
    string
    The ID for the thread this message is part of.
    content
    object[]
    The content of the message.
    plaintext
    string
    A plaintext version of the structured message content.
    url
    string | null
    A URL where the message can be seen. This determines where a user is sent when they click on a reference to this message, such as in a notification. If unset, it defaults to the thread's URL.
    createdTimestamp
    Date
    The timestamp when this message was created. The default value is the current time.
    deletedTimestamp
    Date | null
    The timestamp when this message was deleted, if it was. If unset, the message is not deleted.
    updatedTimestamp
    Date | null
    The timestamp when this message was last edited, if it ever was. If unset, the message does not show as edited.
    iconURL
    string | null
    The URL of the icon to show next to the message. This is only used for action_message messages; other messages show the avatar of the author. If an action_message does not have an icon set, no icon is shown.
    type
    "action_message" | "user_message"
    The type of message this is. A user_message is a message that the author sent. An action_message is a message about something that happened, such as the thread being resolved. The default value is user_message.
    metadata
    EntityMetadata
    Arbitrary key-value pairs that can be used to store additional information.
    extraClassnames
    string | null
    A optional space separated list of classnames to add to the message.
    attachments
    array
    The items attached to this message.
    reactions
    Reaction[]
    The reactions to this message.
    seenBy
    string[]
    A list of IDs of the users that have seen the message.
readStatus
"unread" | "read"
Whether this notification has been read by the recipient yet.
timestamp
Date
The time this notification was sent.
extraClassnames
string | null
A space separated list of classnames to add to the notification.
metadata
EntityMetadata
An arbitrary JSON object specified when the notification was created. This will always be an empty object for Cord's internally-generated notifications (i.e., it can only be non-null for notifications you create via the REST API).

Create a notification #

This endpoint creates and sends a notification. These notifications will appear in the standalone notification list, the notification list launcher, and the notification API.

HTTP Request #

POST https://api.cord.com/v1/notifications
Copy

Required if template includes {{actor}}.
recipientID
required
string
ID of user receiving the notification.
template
required
string
Template for the header of the notification. The expressions {{actor}} and {{recipient}} will be replaced respectively with the notification's actor and recipient. (See below for an example.)
url
required
string
URL of page to go to when the notification is clicked.
iconUrl
optional
string
URL of an icon image if a specific one is desired. For notifications with an actor_id this will default to the sender's profile picture, otherwise it will default to a bell icon.
type
required
"url"
Currently must be set to url. In the future this may specify different types of notifications, but for now only url is defined.
metadata
optional
EntityMetadata
An arbitrary JSON object that can be used to set additional metadata on the notification. When displaying a list of notifications, you can filter the list by metadata value.
Keys are strings, and values can be strings, numbers or booleans.
extraClassnames

string | null
An optional space separated list of classnames to add to the notification.

Example Request #

In this example, suppose a user with the ID 123 and name "Alice Applegate" exists, as well as another user with the ID 456 and name "Bob Bloke". Here is an example request to send a notification from Alice to Bob. When Bob receives this notification, it will say "Alice Applegate sent Bob Bloke a delicious sandwich", and will link tohttp://www.example.com/ when Bob clicks it.

curl "https://api.cord.com/v1/notifications" \
  -X POST \
  -H 'Authorization: Bearer <ACCESS_TOKEN>' \
  -H 'Content-Type: application/json' \
  -d '{
    "actorID": "123",
    "recipientID": "456",
    "template": "{{actor}} sent {{recipient}} a delicious sandwich",
    "url": "http://www.example.com/",
    "type": "url"
  }'
Copy

If the request succeeds, the response will be:

{
    "success": true,
    "message": "Notification created.",
    "notificationID": "<NEW_ID>"
}
Copy

If the request does not succeed, the response will instead contain anerror and message explaining what went wrong:

{
  "error": "<ERROR_CODE>",
  "message": "An explanation of the error code."
}
Copy

Another Example #

Suppose a new user with ID 789 and name "Carol Capable" joins the application, and we would like to notify Alice that this happened. Here is an example request to send such a notification to Alice. When Alice receives this notification, it will say "Carol Capable joined the team", and will link to http://www.example.com/ when Alice clicks it.

curl "https://api.cord.com/v1/notifications" \
  -X POST \
  -H 'Authorization: Bearer <ACCESS_TOKEN>' \
  -H 'Content-Type: application/json' \
  -d '{
    "actorID": "789",
    "recipientID": "123",
    "template": "{{actor}} joined the team",
    "url": "http://www.example.com/",
    "type": "url"
  }'
Copy

The response to this request will look the same as the response to the first example.
