Pagination and nextCursor in header

Hi JF - 

Based on the documentation and your specific use case with cursor-based pagination, here's how to properly access response headers in the HTTP Client snap pagination configuration:
Accessing Response Headers in Pagination
For cursor-based pagination where the next cursor is in a response header like "X-Pagination-Next-Cursor", you need to configure the pagination settings as follows:
1. Has Next Configuration
In the Has Next field, use an expression to check if the header exists:

$headers['X-Pagination-Next-Cursor'] != null

2. Next URI Configuration
   In theNext URIfield, construct your URL with the cursor parameter from the header:

"https://your-api-endpoint.com/api/data?cursor=" + $headers['X-Pagination-Next-Cursor']

Key Points for Header Access

• Use $headers object: Response headers are accessible through the $headers object in pagination expressions
• Exact header name: Use the exact header name as returned by the API (in your case: X-Pagination-Next-Cursor)
• Case sensitivity: Header names are case-sensitive, so ensure you match exactly what the API returns

Complete Example Configuration
For your specific scenario:
Has Next:

$headers['X-Pagination-Next-Cursor'] != null && $headers['X-Pagination-Next-Cursor'] != ""

Next URI:

"https://your-base-url/endpoint?limit=1000&cursor=" + $headers['X-Pagination-Next-Cursor']

Alternative Approaches
If the above doesn't work, you can also try:

• $response.headers['X-Pagination-Next-Cursor']
• Enable Debug mode in the HTTP Client snap to see all available response data structure

Override Headers Section
The "Override headers" section you mentioned is typically used to modify request headers for subsequent pagination calls, not to access response headers. For accessing response header values in pagination logic, use the $headers object in the Has Next and Next URI fields as shown above.
This approach should allow you to properly implement cursor-based pagination using the header values returned by your API. I used SnapGPT to support formulating this response for you.
