Hi everyone,

I’m banging my head on this one and hope someone has already solved it.

What I’m trying to do

Use Make (ex-Integromat) to create new frames on an existing Miro board with a “Make an API call” module.

What actually happens

Every time I hit

POST /v2/boards/uXjVIlv5xlQ=/frames

with a minimal body

{
  "data": {
    "title": "Pourquoi ça fonctionne ici"
  },
  "geometry": {
    "height": 500,
    "width": 1000
  },
  "position": {
    "x": 100,
    "y": 100
  }
}

I get a 404 plus an HTML page that says:

This board is no longer shared, or has been removed

Why that makes zero sense

• Same board ID, same connection:

  • I’m able to get List of Board with the name and the ID and it shows the right one  

• If I copy-paste the exact cURL (token + JSON) into the API Explorer on developers.miro.com, the frame is created instantly.

• Only Make’s “API call” module returns the 404.

Do I need to add the API somewhere else ? Even if I’m connected to the API within Make Connection?

Things I’ve tried (and failed)

1. Hard-coding the Authorization: Bearer … header in Make

Same result every time: 404 “board is no longer shared”.

The ask

• Has anyone managed to create frames from Make (not Postman, not your own script, but the Make module)?

• Is there a hidden header or scope that only the /frames endpoint checks?

• Could Make be stripping something the endpoint needs?

Any hint would be a lifesaver. Merci !
