    try {

        const accessToken = process.env.PINTEREST_ACCESS_TOKEN!
       
        if (!accessToken) throw new Error('Access token is required');

        const request = await fetch(`https://api-sandbox.pinterest.com/v5/pins`, {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
                'Authorization': `Bearer ${accessToken}`
            },
            body: JSON.stringify({
                data: {
                    title: "My first pin",
                    board_id: "1104226471076157432",
                    media_source: {
                        source_type: "image_url",
                        url: "https://dummyimage.com/600x400/000/fff"
                    },
                    description: "My first pin on Pinterest",
                }
            })
        })

        const response = await request.json();
    
    } catch (error: any) {
        console.log(`Error in createPinterestPin: ${error.message}`)
        throw new Error(error)
    }
