### Fetch Protected FINT Resource with Authentication (Bash)

Source: https://fintlabs.github.io/api/tools

The fint-curl script fetches a protected FINT resource. It handles obtaining a bearer token using client credentials from a client.json file and then makes the authenticated API request. It requires 'curl' and 'jq' to be installed and has OS-specific 'stat' commands.

```bash
#!/bin/bash

#set -x

if ! ( curl --version > /dev/null && jq --version > /dev/null)
then
	echo "Required tools curl and jq not installed"
	exit 1
fi

case $(uname -s) in
	Linux) 
		STATSZ="stat -c %s"
		STATMT="stat -c %Y"
		;;

	Darwin)
		STATSZ="stat -f %z"
		STATMT="stat -f %m"
		;;

	*)
		echo "Unknown OS $(uname -s)"
		exit 1
		;;
esac

CLIENT=${CLIENT:-client.json}
TOKEN=${CLIENT}.token

if [[ ! -e $CLIENT ]]
then
    echo "Client settings missing"
    exit 1
fi

eval $(cat $CLIENT | jq -r  "\"OAUTH_ID=\"+.clientId, \"OAUTH_SECRET=\"+.openIdSecret, \"OAUTH_USER=\"+.username, \"OAUTH_PWD=\"+.password, \"SCOPE=\"+.scope, \"IDP_URL=\"+.idpUri, \"ASSET_ID=\"+.assetId")

if [[ ! ( -e $TOKEN ) || $($STATSZ $TOKEN) -lt 10 || ( $(( $(date +%s) - $($STATMT $TOKEN) )) -gt 3500 ) ]]
then
    curl -f -s ${IDP_URL:-https://idp.felleskomponent.no/nidp/oauth/nam/token} -u "${OAUTH_ID}:${OAUTH_SECRET}" -d grant_type=password -d username="${OAUTH_USER}" -d password="${OAUTH_PWD}" -d scope="${SCOPE:-fint-client}" | jq -r '.access_token' > $TOKEN
fi

if [[ $($STATSZ $TOKEN) -lt 10 ]]
then
	echo "Authorization failure"
	exit 1
fi

curl -H "Authorization: Bearer $(cat $TOKEN)" -H  "accept: application/json;charset=UTF-8" -H "Content-Type: application/json" -H  "x-org-id: ${ASSET_ID:-fintlabs.no}" -H  "x-client: ${OAUTH_USER}" $*
```

```json
{
    "_links": {
        "self": [
            {
                "href": "/administrasjon/personal/person?size=25000&offset=0"
            }
        ],
        "next": [
            {
                "href": "/administrasjon/personal/person?size=25000&offset=25000"
            }
        ]
    },
    "total_items": 123456,
    "size": 25000,
    "offset": 0
}
```

```json
{
    "_links": {
        "self": [
            {
                "href": "/administrasjon/personal/person?size=25000&offset=100000"
            }
        ],
        "prev": [
            {
                "href": "/administrasjon/personal/person?size=25000&offset=75000"
            }
        ]
    },
    "total_items": 123456,
    "size": 23456,
    "offset": 100000
}
```

### FINT API - Get All Objects of a Class

Source: https://fintlabs.github.io/api/overview

This operation retrieves all instances of a specified class from the FINT cache. It returns a JSON object containing a list of entries under '_embedded._entries', along with pagination details and links. The structure is consistent for all main classes in the FINT information model.

```json
{
    "_embedded": {
        "_entries": [
            {
                
            },
            {
                
            }
        ]
    },
    "_links": {
        "self": [
            {
                "href": "..."
            }
        ]
    },
    "total_items": 111,
    "size": 111,
    "offset": 0
}

```

--------------------------------

### Get Objects Updated Since Timestamp

Source: https://fintlabs.github.io/api/overview

Retrieves a collection of objects that have been updated (added or modified) after a specified timestamp. Supports pagination and `size=0` for no updates.

```APIDOC
## Get objects updated since timestamp

`/domain/package/class?sinceTimeStamp=<time>`, i.e. `/administrasjon/personal/personalressurs?sinceTimeStamp=1559551091034`

Returns a collection of all objects that have been updated (added or modified) later than the provided timestamp. The response looks like this:

```json
{
    "_embedded": {
        "_entries": [
            {
                
            },
            {
                
            }
        ]
    },
    "_links": {
        "self": [
            {
                "href": "..."
            }
        ]
    },
    "total_items": 24324,
    "size": 2,
    "offset": 0
}
```

If `size` is `0`, this indicates that there are no new updates since the given timestamp.
This request can also be combined with pagination using `size` and `offset` in case a large number of items have been updated.
**Note:** When FINT API restarts, all items are regarded new. This means a `sinceTimeStamp` parameter from before the restart will return all items. It is therefore recommended to use pagination as well if the result is large.

### Query Parameters
- **sinceTimeStamp** (string) - Required - A timestamp (in milliseconds since epoch) to filter updates.
- **size** (integer) - Optional - Number of items to return. Limits the response to contain maximum `size` elements.
- **offset** (integer) - Optional - Position in list to start returning items from. Skips `offset` items.

### Example
`GET /administrasjon/personal/personalressurs?sinceTimeStamp=1559551091034&size=10&offset=0`
```

--------------------------------

### Get Cache Size (JSON Response)

Source: https://fintlabs.github.io/api/overview

```json
{
  "size": 10632
}
```

--------------------------------

### Get Objects Updated Since Timestamp (JSON Response)

Source: https://fintlabs.github.io/api/overview

```json
{
    "_embedded": {
        "_entries": [
            {
                
            },
            {
                
            }
        ]
    },
    "_links": {
        "self": [
            {
                "href": "..."
            }
        ]
    },
    "total_items": 24324,
    "size": 2,
    "offset": 0
}
```

--------------------------------

### Get Last Updated Timestamp (JSON Response)

Source: https://fintlabs.github.io/api/overview

Provides the timestamp indicating when the cache for a given class was last updated. The response is a JSON object with a 'lastUpdated' key, holding the timestamp as a string. This helps in determining data freshness.

```json
{
  "lastUpdated": "1559551091034"
}
```

--------------------------------

### Creating New Objects

Source: https://fintlabs.github.io/api/updating

Use the POST method to create new objects. The request body must be a complete resource, including links to other resources.

```APIDOC
## Creating New Objects

### POST /domain/package/class

Use the POST method to create new objects in the FINT API.

### Method

POST

### Endpoint

`/domain/package/class`

*Example:* `/administrasjon/personal/fravar`

### Request Body

- **resource** (object) - Required - The complete resource object to be created, including `_links` to other resources.
  - *Note*: Internal identifiers controlled by the backend system can be omitted.
```

--------------------------------

### Pagination of Results

Source: https://fintlabs.github.io/api/overview

This endpoint supports pagination using `size` and `offset` query parameters to manage large sets of resources. The response includes links for next/previous pages and the total number of items.

```APIDOC
## Pagination of result (`size` and `offset`)

For areas where there are a large number of resources, the API supports pagination. This is controlled by two query parameters:

| parameter | description  
---|---
`size` | Number of items to return. Limits the response to contain maximum `size` elements.  
`offset` | Position in list to start returning items from. Skips `offset` items.  

The response contains `prev` or `next` entries within `_links` if there are more items either before or after (or both) compared to the current page.
The `total_items` attribute in the response can also be used to determine number of requests required.

**Example: 25,000**
Fetch first page: `/administrasjon/personal/person?size=25000&offset=0`

First 25,000 elements are returned. The response contains the following:

```json
{
    "_links": {
        "self": [
            {
                "href": "/administrasjon/personal/person?size=25000&offset=0"
            }
        ],
        "next": [
            {
                "href": "/administrasjon/personal/person?size=25000&offset=25000"
            }
        ]
    },
    "total_items": 123456,
    "size": 25000,
    "offset": 0
}
```

Keep following the `next` link as long as it’s present, for a total of five requests.
Each response will indicate 123,456 total items. The first four responses will have a `size` of 25,000, but the last response will have a size of 23,456 and no `next` link:

```json
{
    "_links": {
        "self": [
            {
                "href": "/administrasjon/personal/person?size=25000&offset=100000"
            }
        ],
        "prev": [
            {
                "href": "/administrasjon/personal/person?size=25000&offset=75000"
            }
        ]
    },
    "total_items": 123456,
    "size": 23456,
    "offset": 100000
}
```

### Query Parameters
- **size** (integer) - Optional - Number of items to return. Limits the response to contain maximum `size` elements.
- **offset** (integer) - Optional - Position in list to start returning items from. Skips `offset` items.
```

--------------------------------

### Asynchronous Operations

Source: https://fintlabs.github.io/api/updating

FINT APIs use asynchronous operations for updates, allowing time for propagation through FINT components and adapters before backend processing.

```APIDOC
## Asynchronous Operations

FINT APIs handle updates asynchronously due to propagation delays. The process involves the client initiating an update, the FINT API responding with `202` and a `Location` header for status tracking, and the client polling the status resource until the operation completes.

### Process Flow

1.  **Client Initiates Update**: Sends a request to create, modify, or delete a resource.
2.  **FINT API Validation**: Validates syntax and responds with `202 Accepted` and a `Location` header pointing to a `/status/<uuid>` resource.
3.  **Client Fetches Status**: The client polls the `/status/<uuid>` resource.
    *   If pending, the FINT API responds with `202 Accepted`.
4.  **Operation Completion**: 
    *   **Success (Create/Update)**: `201 Created` with a `Location` header to the updated resource and the resource payload.
    *   **Success (Delete)**: `204 No Content`.
    *   **Backend Rejection**: `400 Bad Request` with an error message.
    *   **Conflict**: `409 Conflict` with the conflicting original information.
    *   **Temporary Failure**: `500 Internal Server Error` with an error message, allowing the client to retry.

The status resource is valid for 30 minutes.
```

--------------------------------

#!/usr/bin/python

import jsonschema
import requests
import sys
import json
from tqdm import tqdm

r = requests.get(sys.argv[1])

schema = r.json()

data = json.load(sys.stdin)

validator = jsonschema.Draft7Validator(schema)

print "Validating", data["total_items"], "items..."

errors = 0

with open("errors.log", "a") as logfile:
	for item in tqdm(data["_embedded"]["_entries"]):
		try:
			validator.validate(item)
		except Exception as e:
			errors += 1
			print >> logfile, item
