Working with Low Code Attachments

We omit most of the data returned by these endpoints.

We replace the important data with variables, such as $RECORD_ID.

Obtain a Signed Download URL

Obtain signed URL using attachment read or attachment list endpoints:

attachment read: GET $BASE_URL/compose/namespace/$NAMESPACE_ID/attachment/record/$ATTACHMENT_ID
attachment list: GET $BASE_URL/compose/namespace/$NAMESPACE_ID/attachment/record

Response object structure:

{
  "attachmentID": "$ATTACHMENT_ID",
  "ownerID": "$USER_ID",
  "url": "$ATTACHMENT_ORIGINAL_URL",(1)
  "previewUrl": "$ATTACHMENT_PREVIEW_URL",(2)
  "name": "$FILENAME_ORIGINAL",
  "meta": {...},
  "namespaceID": "$NAMESPACE_ID"
}

1	`url` contains a signed URL to the attachment.
2	`previewUrl` contains a signed URL to the preview version of the attachment (when available).

Example Request

curl "$BASE_URL/compose/namespace/$NAMESPACE_ID/attachment/record/$ATTACHMENT_ID" \
 -H "Authorization: Bearer $JWT";

Example Response

{
  "response": {
    "attachmentID": "$ATTACHMENT_ID",
    "ownerID": "$USER_ID",
    "url": "$ATTACHMENT_ORIGINAL_URL",
    "previewUrl": "$ATTACHMENT_PREVIEW_URL",
    "name": "$FILENAME_ORIGINAL",
    "meta": {...},
    "namespaceID": "$NAMESPACE_ID"
  }
}

Access the Attachment

Use the $ATTACHMENT_ORIGINAL_URL to access any downloadable attachment. You can either download the attachment manually, use a HTTP client (such as Axios), or display the attachment using <img src="…" or something similar.
