Glip Message Attachments allow developers to attach rich content to posts with formatting and color indicators to more easily convey a large amount of information. This is available with both Inbound Webhooks and the REST API. Using Glip Message Attachments one can:

  • Add up to 20 attachments per post, each rendered as its own section
  • Add an author, title, pretext, text to each attachment
  • Select a color for each attachment to indicate importance or subject
  • Render short metadata using the fields property
  • Render photos and images

What to be aware of when using message attachments

  • All fields except text have a character limit of 300 bytes.
  • The cummulative size limit for all attachments is 1.5M bytes.
  • "Glipdown," a RingCentral flavor of Markdown, provides some text formatting options (bold, italics, links, etc.)

Posting Messages via the REST API

What follows is an example message that can be posted to the REST API.

REST API <> Inbound Glip Webhooks

Posting a "card" via the REST API as described below utilizes almost the same message structure as discussed in Working with Glip Webhooks. But be advised, they are not identical.

  "text": "Body of the post",
  "attachments": [
      "type": "Card",
      "fallback": "Attachment fallback text",
      "color": "#00ff2a",
      "intro": "Attachment intro appears before the attachment block",
      "author": {
          "name": "Author Name",
          "uri": "",
          "iconUri": ""
      "title": "Attachment Title",
      "text": "Attachment text",
      "imageUri": "",
      "thumbnailUri": "",
      "fields": [
          "title": "Field 1",
          "value": "A short field",
          "style": "Short"
          "title": "Field 2",
          "value": "[A linked short field](",
          "style": "Short"
          "title": "Field 3",
          "value": "A long, full-width field with *formatting* and [a link](",
          "style": "Long"
      "footnote": {
        "text": "Attachment footer and timestamp",
        "iconUri": "",
        "time": "2018-01-05T18:52:35.993311508-08:00"

Posting the above to the REST API will result in a message and card that appears as follows:

Posting Multiple Cards at Once

The following is an example set of cards created by a single request containing three attachments. Each attachment results in its own card, and contains multiple fields. This example shows message attachments created through the RingCentral Glip Salesforce integration.
