mediaItems is an array used by endpoints like:
  • Create Post (POST /v2/access/posts)
  • Send Message (POST /v2/access/chats/{userId}/messages)
  • Create Mass Message (POST /v2/access/mass-messages)
This page only covers what values you can put inside the mediaItems array.

​
Accepted Item Formats

Each element in mediaItems can be one of the following:
FormatExampleWhen to use
Vault media ID (number)12345You already have a vault media ID and want to reuse it
Vault media ID (numeric string)"12345"Same as above, but your ID is a string
Upload reference (mediaUploadId)"upload:550e8400-e29b-41d4-a716-446655440000"You just uploaded media via /v2/access/uploads/* and want OFAuth to resolve it to a vault ID for you
External URL (HTTP/HTTPS)"https://example.com/image.jpg"You want to attach a remotely hosted file by URL
You can mix formats in the same array. Order is preserved.

​
Upload References Are Single-Use

If you pass a mediaUploadId (the value returned by POST /v2/access/uploads/init) inside mediaItems, OFAuth resolves it and then consumes the upload reference.
Upload references are single-use. Once a mediaUploadId is used in a post or message, it cannot be reused.
If you need to attach the same media multiple times, store and reuse the vault media ID instead.

​
Examples

​
Use a vault media ID

{
  "text": "New content!",
  "mediaItems": [12345, 67890]
}

​
Use an upload reference

{
  "text": "Just uploaded this",
  "mediaItems": ["upload:550e8400-e29b-41d4-a716-446655440000"]
}

​
Mix formats

{
  "text": "Bundle drop",
  "mediaItems": [
    12345,
    "67890",
    "upload:550e8400-e29b-41d4-a716-446655440000",
    "https://example.com/extra.jpg"
  ]
}

Validation Rules (Quick)

  • Non-numeric strings that are not an upload: reference and not an http(s):// URL are rejected.
  • Only http:// and https:// URLs are accepted.
  • If an upload reference is invalid/expired/unused (not ready), the request fails with 400.
