How can I upload and image to Trello a trello, but NOT set it as Cover (which is the default setting)

Question

I'm uploading images to a Trello Card using the Trello API. Trello by default set the image as the cover image. The API documentation says there is a setCover option but I cannot get it work.

https://developer.atlassian.com/cloud/trello/rest/api-group-cards/#api-cards-id-attachments-post

def __upload_image_to_card(self, connection: dict, card: dict, image_path : str, cover=False):
    params = (
        ('key', connection['trello_api_key']),
        ('token', connection['trello_api_token']),
    )
    
    values = {
        'file': (image_path, open(image_path, 'rb')),
        'setCover' : (cover),
    }

    # TODO: Move to node_manager
    response = requests.post('https://api.trello.com/1/cards/%s/attachments' % card['id'], params=params, files=values).json()

I've tried switching between a boolean and string, have tried removing the brackets. I've even added a error key in values to see if I can get a different response. None stopped the image from being uploaded and none prevented the image from becoming the default image.

Would appreciate any help.

setCover should be in params, not in files/values. You may also need to make it str(cover).lower() since it's expecting true/false and not True/False.

# since you using a list of tuples:
params = (
    ('key', connection['trello_api_key']),
    ('token', connection['trello_api_token']),
    ('setCover', cover),
)

Or as a dict:

params = {
    'key': connection['trello_api_key'],
    'token': connection['trello_api_token'],
    'setCover': cover,
}
