This can present them with an app ID and app secret, which they might want to use to authenticate their requests to the API. As soon as registered, builders can use the Graph API to carry out a wide range of operations, together with:
Endpoint with HTTP verbs
Endpoint is a URL that builders can request to work together with the Graph API. The Graph API helps the next HTTP verbs at endpoints:
| HTTP Verb | Description |
|---|---|
| GET | Retrieves knowledge from the endpoint |
| POST | Creates a brand new object or updates an present object |
| PUT | Updates an present object |
| DELETE | Deletes an object |
Producing App Entry Tokens
App entry tokens are long-lived tokens that can be utilized to make API calls on behalf of a consumer. They’re generated utilizing the Graph API Explorer device and require a sound app secret and consumer entry token. To generate an app entry token, comply with these steps:
