# Export Every Football API Page Without Silent Gaps

A successful first page is not a complete season export. The match collection returns data plus pagination metadata including page, limit, total, has_more and next_page. Use the continuation information to decide whether another page is required, and retain the request filters with the export. A list of one hundred results can look plausible even when several hundred were never fetched.

## Define what a complete export means

A successful first page is not a complete season export. The match collection returns data plus pagination metadata including page, limit, total, has_more and next_page. Use the continuation information to decide whether another page is required, and retain the request filters with the export. A list of one hundred results can look plausible even when several hundred were never fetched.

Set a maximum page budget before starting. That protects an unattended job from a repeated continuation value or a much larger query than intended. The limit is a safety boundary, not an excuse to label a partial result complete. If the budget is exhausted while more pages remain, keep the job incomplete and report the reason.

## Validate each transition

A loop should verify that the response page equals the page requested, that next_page advances when has_more is true, and that the terminal page has no next page. Deduplicate stable match IDs as an additional check. Conflicting duplicate records need review or a defined reconciliation strategy; silently dropping them can hide movement in a changing dataset.

The example supplies two synthetic pages through a callable, so the same collection function can be tested without credentials or network access. It checks both a normal two-page export and an invalid repeated continuation. The metadata and fields used are projections from the published match response contract.

## Run the reproducible example

This Python 3 example uses deliberately synthetic inputs, not a downloaded match or a forecast for a real fixture. Save it as example.py and run python3 example.py. It uses only the standard library and its assertions check the behavior discussed here. Replace the fixture inputs with validated API records when connecting your application; demo identifiers are not production lookup values.

**Complete offline example**

```python
def collect(fetch, max_pages=20):
    result, seen, page = [], set(), 1
    for _ in range(max_pages):
        payload = fetch(page)
        meta = payload["meta"]
        if meta["page"] != page:
            raise ValueError("wrong page returned")
        for row in payload["data"]:
            if row["id"] in seen:
                raise ValueError("duplicate identity; inspect changing dataset")
            seen.add(row["id"])
            result.append(row)
        if meta["has_more"] is False:
            if meta["next_page"] is not None:
                raise ValueError("invalid terminal page")
            return result
        following = meta["next_page"]
        if type(following) is not int or following <= page:
            raise ValueError("non-advancing pagination")
        page = following
    raise ValueError("page budget exhausted")

pages = {
 1:{"data":[{"id":"match_a"}],"meta":{"page":1,"has_more":True,"next_page":2}},
 2:{"data":[{"id":"match_b"}],"meta":{"page":2,"has_more":False,"next_page":None}}
}
assert [r["id"] for r in collect(pages.__getitem__)] == ["match_a","match_b"]
pages[1]["meta"]["next_page"] = 1
try:
    collect(pages.__getitem__)
except ValueError as error:
    assert str(error) == "non-advancing pagination"
else:
    raise AssertionError("bad continuation accepted")
print("two pages collected; repeated continuation rejected")
```

## Read the result

The first test collects both synthetic match IDs. The second changes the continuation to repeat page one and confirms that the loop stops with an explicit error. It never returns that broken walk as a completed export.

## Keep writes recoverable

Write incoming records to a staging area and promote the export only after every page succeeds. If a request fails halfway through, retain the staging job and its filters, but do not replace the previous complete export with a partial dataset. For a database sink, use stable IDs and idempotent writes so repeating a safely recovered page does not duplicate rows.

Offset pagination over a changing collection is not a snapshot guarantee. A fixture inserted or reordered during the walk can create duplicates or gaps. Prefer bounded historical windows when appropriate, repeat an overlap window for correction detection, and compare identities before claiming completeness. A total count alone cannot prove every intended ID was retrieved.

## Observe the page walk

Log page numbers, counts, request IDs and the job's terminal state without logging bearer keys. Distinguish an empty valid page from a transport error or a malformed response. An empty query can be a complete and correct result, while an exception should preserve the last successful state for investigation.

Before going live, test zero rows, one page, a full last page, a repeated page and a failed middle request. These cases are cheap to reproduce with fixtures and catch the pagination mistakes that a single successful API call cannot expose. The final artifact should say which filters and retrieval period it represents.

## Connect this to your project

Wrap this collector around a server-side HTTP client with bearer authentication and explicit timeouts. Start with a small known date window and compare the resulting IDs manually before expanding. The existing Python guide covers request handling, while the endpoint contract defines the filters and envelope this loop expects.
