+## Using pagination helper
+
+In the previous examples, we used the `requests` library to make HTTP requests to the GitHub API and handled pagination manually. `dlt` provides a helper function `paginate` that simplifies this process. The `paginate` function takes a URL and optional parameters (quite similar to `requests`) and returns a generator that yields pages of data.
+
+Let's rewrite the previous example using the `paginate` helper:
+
+```py
+    import dlt
+    from dlt.sources.helpers.rest_client import paginate
+
+    @dlt.resource(
+        table_name="issues",
+        write_disposition="merge",
+        primary_key="id",
+    )
+    def get_issues(
+        updated_at=dlt.sources.incremental("updated_at", initial_value="1970-01-01T00:00:00Z")
+    ):
+        for page in paginate(
+            "https://api.github.com/repos/dlt-hub/dlt/issues",
+            params={
+                "since": updated_at.last_value,
+                "per_page": 100,
+                "sort": "updated",
+                "direction": "desc",
+                "state": "open",
+            },
+        ):
+            yield page
+
+    pipeline = dlt.pipeline(
+        pipeline_name="github_issues_merge",
+        destination="duckdb",
+        dataset_name="github_data_merge",
+    )
+    load_info = pipeline.run(get_issues)
+    row_counts = pipeline.last_trace.last_normalize_info
+
+    print(row_counts)
+    print("------")
+    print(load_info)
+```
