There is no limitation to the amount of nesting of levels that can occur here. Mithilfe der Schnittstelle können wir dann die Daten mehr oder weniger direkt nach Excel importieren.
The field expansion feature of the Graph API allows you to effectively nest multiple graph queries into a single call. Certain resources, including most of Ads API, are unable to utilize field expansion on some or all connections.
For example, in a single call, you can ask for the first N photos of the first K albums. The response maintains the data hierarchy so developers do not have to weave the data together on the client. This is different from the batch Requests feature which allows you to make multiple, potentially unrelated, Graph API calls in a single request.
There is no limitation to the amount of nesting of levels that can occur here. You can also use a. This is easier to understand by seeing it in action, so here's an example query that will retrieve up to five albums created by someone, and the last five posts in their feed. We can then extend this a bit more and for each album object, also retrieve the first two photos, and people tagged in each photo:. Now we can extend it again by retrieving the name of each photo, the picture URL, and the people tagged:.
You can see how field expansion can work across nodes, edges, and fields to return really complex data in a single request. Some Graph API endpoints can take parameters that are very large. If your requests end up being larger than a couple thousand characters, you may start seeing server errors since our servers will reject very large GET requests. The standard version of the Graph API is designed to make it easy to get data for an individual object and to browse connections between objects.
It also includes a limited ability to retrieve data for a few objects at the same time. If your app needs the ability to access significant amounts of data at once, or you need to make changes to several objects at once, it is often more efficient to batch your queries rather than make multiple individual HTTP requests.
Batch requests are explained in a separate guide but you can read more about multiple ID lookup below. You can make a single GET request that retrieves multiple nodes by using the? For example, to lookup the Facebook Developers page and the current session user in a single request, you could use the following Graph API call:.
This can also work with edges as long as all the requested IDs have the requested edge. Note that while field filtering, field expansion, and limiting will work with these multiple-ID lookups, you will get an error if one of the objects does not have any of the requested fields. The Graph API supports introspection of nodes.
This enables you to see all of the edges a node has without knowing its type ahead of time. The resulting JSON will include a metadata property that lists all the supported edges for the given node:. The syntax for search is:. All Graph API search queries require an access token included in the request.
You need a user access token to execute a search. Search for a place. Weil da grade was umgestellt wird. Bei mir funktioniert es auch nicht!! Liegt keineswegs an Google sondern wohl an den Providern.
