Pagination in Shopify API

Hi Ambhika_07 ,

To achieve this in Power BI, you could use the Power Query M language to programmatically follow the pagination links.

Please try below steps:

1. Initial API Call: Start by making an initial API call to fetch the first set of data along with the pagination link from the response headers.

2. Parse Response Headers: Extract the "next URL" from the response headers. This will require parsing the headers to locate the URL for the next page of data.

3. Recursive Function: Create a recursive function in Power Query M that takes the "next URL" as an input, fetches the data, and then calls itself with the new "next URL" found in the response headers of the subsequent call. This function should continue to execute until there is no "next URL" found, indicating the end of the data.

Here's a simplified example of how you might start to structure this function in Power Query M:

et
    FetchData = (url as text) as table =>
    let
        Source = Json.Document(Web.Contents(url)),
        Data = Source[data],
        NextUrl = Source[headers][next_url], // Adjust this based on actual header structure
        Output = if NextUrl <> null then Table.Combine({Data, @FetchData(NextUrl)}) else Data
    in
        Output
in
    FetchData("YourInitialShopifyApiUrl")

Note: This is a simplified example. You'll need to adjust the logic to match the specific structure of the Shopify API response and ensure you handle authentication headers if required.

If you struggle with connecting to Shopify API, there are ready-made solutions for extracting data automatically from Shopify. Here is one of them: https://vidi-corp.com/shopify-power-bi-connector/
