NocoDB Upload Attachment Issues with HTTP Node

[Garrett_Fry]

Has anyone successfully uploaded an OpenAI generated image to NocoDB via the HTTP Request Node? I feel like I have tried everything. The node works but all I get is a “Null” in the “Cover Image” Attachment field.

HTTP Node:

I suggest you do this in two steps:

First, upload the file to storage.
Endpoint: POST /api/v2/storage/upload
Auth: header xc-token: <API_TOKEN>
Body: multipart/form-data with a single file field containing the binary.
Response: an array with the file description(s) (url, title, mimetype, size, etc.). This array is what goes into the Attachment column.

Then create/update the row with the attachment:
Endpoint: POST /api/v2/tables/{TABLE_ID}/records (or PATCH /…/records/{id})
Auth: xc-token
Content-Type: application/json
{
“Title”: “Teaching Kids to Tie Shoes”,
“Cover Image”: [ /* paste the answer from step 1 here */ ]
}
