Metamask: Pinata PIN List API Fetching Unpinned Images and Files
As a Pinata user, you’re likely familiar with accessing your Pinata Cloud data through their official APIs. However, I’ve encountered an issue where unpinning several images and files from my Pinata account continues to fetch new ones from the Pinata PIN List API despite my efforts.
The Problem
When pinning or unpining content on Pinata, you typically need to update the Pin List API accordingly to reflect changes in your data. However, it seems that Pinata’s API is not respecting these updates. Specifically:
- Unpinning multiple items at once may result in fetching new images and files from the PIN List API.
- If unpinning specific pins or content types (e.g., assets), the API might still attempt to fetch associated items.
The Solution
To resolve this issue, I’ve explored several options:
- API Keys: Pinata’s documentation suggests that setting a custom API key can help prevent issues like these. However, using an API key without proper authentication may result in unauthorized access and security concerns.
- Pin List Updates
: Pinata provides APIs to update the PIN List itself (e.g.,
pinList
endpoint). While this might seem like a potential solution, it requires more complex implementation and understanding of Pinata’s internal data structures.
The Solution: Using Webhooks
After researching alternative approaches, I’ve found that using webhooks can be an effective way to address this issue. Here’s the proposed solution:
Step-by-Step Instructions
- Set up a Pinata webhook: Create a new webhook on your Pinata account by following the instructions in their documentation.
- Configure the webhook to catch unpinning events: Set up the webhook to detect unpinned items and send notifications or updates when necessary.
- Use the
fetch
API to refresh pin list data: When an item is unpinned, use thefetch
API to fetch updated pin list data from Pinata’s servers. This should prevent new images and files from being fetched.
Example Code
// Assume you have a Webhook endpoint (e.g.,
const webhookUrl = '
const apiKey = 'YOUR_API_KEY';
fetch(${webhookUrl}?action=update&api_key=${apiKey}
)
.then(response => {
if (!response.ok) {
throw new Error('API response:', response.status);
}
return response.json();
})
.then(data => {
// Update pin list data using the fetched information
const updatedPinList = { ...data.pinList }; // assume 'pinList' is an array of objects
// update your local database or storage with the new pin list data
})
.catch(error => console.error('Error:', error));
Conclusion
By setting up a webhook to catch unpinning events and using the fetch
API to refresh pin list data, you can effectively resolve the issue of fetching unpinned images and files from your Pinata account. This solution requires some technical expertise, but it should provide reliable and efficient access to your Pinata Cloud data.
Keep in mind that this is just one possible solution, and there might be other approaches or workarounds depending on your specific use case.
