I am trying to copy the cover from one card to another using Butler HTTP requests. I was able to set the colors this way but when I tried setting the cover like this : It gives an error: Since the file is already uploaded to trello shouldn't this be an allowed image service? Is there any way I can set the cover? Is it possible by getting the attachment id? If so how?

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Since the file is already uploaded to trello shouldn't this be an allowed image service?

Is there any way I can set the cover? Is it possible by getting the attachment id? If so how?

Take a look at this

Hello @Death Vortex

As per the REST API documentation for the Update a Card endpoint, if you want to refer to an image using the url parameter, you can only refer images that are hosted in Unsplash for the cover:

url. Used if making an image the cover. Only Unsplash URLs work.

Urls to any other image location / place are not allowed.

To use an image that's attached to any card as the cover for any other card, you have to refer to it by its ID:

idAttachment. ID of an attachment on the card. Used if setting an attached image as the cover.

However, Butler currently does not have a variable such as {attachmentid} that will return the ID of an attached image, so there is no way to automate that aspect of the rule.

You are essentially stuck with having to manually put the ID of the image into your HTTP PUT request in your Butler rule:

{"key" : "[api_key]","token" : "[api_token]","cover" : {"idAttachment" : "ABCD1234etcetc","size" : "normal" }}

Bummer, eh

Hi, @[deleted]:

I was trying to find a getaround and I'm pretty sure it's possible but I may need some tweak.

My idea was:

Look up at the card I want the cover from
Get the cover attachment
Put this attachment as a new attachment of the destination card, defining it as a cover.

My rules look like this

It almost works as I have a new attachment in the destination card but it's not an image, so if I use "setCover": "true" in the last payload, I get the following error message.

Maybe @milynnus as some idea too?

I don’t work with native Trello api a lot but based on your post, the issue is not the setcover but you did not get a image file as you indicated.

I am able to get this if I make one of the attachment as a cover vs a cover that is taken from the unsplash. Same results when I used the python library and native api call.

Do note the url structure.

Creating the endpoint proves to be a bit more challenging than I thought.

You cannot use the url because it complains about being unable to generate a preview.
If you download and use the file, you cannot setCover at the same time

I have not done the documentation. Here's from redoc. Use the same endpoint from the documentation earlier in the post.

note: there is a 10s timeout which will affect large cover files.

I, @milynnus . As I said, I'm no expert in this and I have some doubt.
Is it safe to send key & token as params for these requests?

Thanks

It is fair to be concern. I don’t it is any difference in using Trello API. I think the fundamental difference is the provider of the third party service. In an earlier implementation I have registered users. So their credentials will be kept in a database or a .secret folder such that it will be called only during program execution. I have not incorporated it here so the service is without charge.

If you go into Trello Automation you will find your credentials in plain text. In my implementation I made sure that in Deta visor, the equivalent, it is not shown and based on their process they keep only the last 30 transactions for testing purpose. For production and better performance, visor is to be turned off.

Not sure there is any added advantage but each trigger runs as a separate process in a serverless container environment.

For added assurance, you can host your own micro in Deta such that only you know the endpoint url, embedded your credentials in .env or Deta Base. I used python with a client but under the covers it calls the Trello Api.
