Uploading Product Images VIA API and Primary Image Wanted Not Showing as Primary

[slider1234]

As the title of this post states, I'm using the API to upload 7 images for a listing and that works perfect, but I want the image that is watermarked to be the primary image and it isn't. The watermarked image is actually showing as the last image in the listing.

I tried two different things:

1. I did attempt to make sure the watermarked image was the first image uploaded and that made no difference.
2. I also has a thought that the filenames were being listed in alphabetic order, so i change the watermarked.png file to 1watermarked.png and that made no difference.
3. Of course I did search Google and even attempted to use ChatGPT4 to get an answer and both have resulted in no answer.

Any help with this would be much appreciated.

i figured it out. It needed a "rank". i didn't even know that existed until now.

here is a simplified version made in Python if anyone else runs into the same problem.

`import requests
from requests_toolbelt.multipart.encoder import MultipartEncoder

API_KEY = 'your_api_key'
OAUTH_TOKEN = 'your_oauth_token'
SHOP_ID = 'your_shop_id'
LISTING_ID = 'your_listing_id'

primary_image_path = 'path/to/your/primary_image.png' # This will be set as the primary image (rank 1)
second_image_path = 'path/to/your/second_image.png'
third_image_path = 'path/to/your/third_image.png'

def upload_image(listing_id, file_path, rank):
"""Uploads an image to the specified listing with a specified rank."""
url = f'https://api.etsy.com/v3/application/shops/{SHOP_ID}/listings/{listing_id}/images'
with open(file_path, 'rb') as f:
m = MultipartEncoder(
fields={
'image': ('filename', f, 'image/png'),
'rank': str(rank) # Sets the rank of the image
}
)
headers = {
'x-api-key': API_KEY,
'Authorization': f'Bearer {OAUTH_TOKEN}',
'Content-Type': m.content_type
}
response = requests.post(url, data=m, headers=headers)
if response.ok:
print(f'Image uploaded successfully. Image ID: {response.json().get("image_id", "Not Available")}')
else:
print(f'Failed to upload image. Status: {response.status_code}')
print(response.json())

if name == 'main':
upload_image(LISTING_ID, primary_image_path, rank=1) # Upload the primary image first
upload_image(LISTING_ID, second_image_path, rank=2) # Upload the second image
upload_image(LISTING_ID, third_image_path, rank=3) # Upload the third image
