Trouble uploading images to Notion: Encountering 403 Forbidden error

Other Questions Notion

I’m trying to add pictures to my Notion page but I’m hitting a wall. I’m using the unofficial API because the official one doesn’t let me upload local images. I got connected to my page using the token_v2 and even made an image block. But when I try to actually put the image in, I get this 403 Forbidden error. It’s driving me crazy!

Here’s what my code looks like:

from notion_connector import NotionConnect

def add_monthly_pic():
    my_token = get_secret_token('v2_key')
    notion = NotionConnect(my_token)
    
    home_url = 'https://www.notion.so/My-Page-1234567890'
    my_page = notion.open_page(home_url)
    
    pic_block = my_page.add_block('picture')
    pic_block.set_image('C:/MyFiles/Reports/monthly_pic.jpg')
    pic_block.move_to_top()
    my_page.delete_first_block()

Anyone know what I’m doing wrong? I’ve been stuck on this for ages. Help!

I’ve encountered this issue myself, and it can be quite challenging. The 403 Forbidden error often occurs because Notion’s security protocols are designed to prevent unauthorized API requests, especially when using unofficial methods.

In my experience, switching strategies helped alleviate the problem. Instead of relying solely on the API for image uploads, I started using Notion’s web clipper. This method isn’t flawless, but it bypasses the security restrictions by using the same mechanism as the web interface.

Another approach was to upload images externally to services like Imgur or Google Drive and then embed them in Notion. While this adds a step, it reliably avoids the issues with direct uploads through the unofficial API.

I recommend keeping a close watch on Notion’s updates, as future changes may eventually support direct image uploads via their API.

hey there! ive run into this too. its annoying right? sounds like notion’s security is blocking ur api requests. have u tried using the web clipper instead? its not perfect but it works better than the api sometimes. or maybe upload pics to imgur first and then link em in notion? just ideas. hope u figure it out!

Hey there! I’ve dealt with this frustrating issue too. The 403 error usually pops up because Notion’s security is pretty strict with unofficial API requests. Here’s what worked for me:

Instead of fighting with the API, I started using Notion’s web clipper for images. It’s not perfect, but it gets around those pesky security blocks.

Another trick is to host your images elsewhere first. I use Imgur a lot - just upload there, then paste the link into Notion. It’s an extra step, but it’s way more reliable than battling the API.

Also, keep an eye on Notion’s updates. They might eventually add proper image upload support to their official API. Until then, these workarounds should help you out. Good luck!
