# Warmup API

The Warmup API allows you to proactively cache your images in the Cloudimage infrastructure for faster processing before receiving the first request from your end users. We recommend to warm-up Cloudimage in the following cases:

* upon launching a new collection of thousands/millions of images - to make sure that at launch time, all images will be pre-processed and rocket fast for end users;
* at upload - to make sure that the uploaded image is already pre-processed to be immediately accessible for end users;
* when dealing with large images (large animated GIF files, gigapixels pictures, etc.) - as pre-processing is important to save time on first load;
* performance is a top priority even if it’s on the first load.

## Creating a warm-up task <a href="#od_4b6c13e1" id="od_4b6c13e1"></a>

You can provide a list of your images either in a txt/csv file or in the request's body.

POSThttps\://warmup.api.cloudimage.com/warmup/urls

### URL list from a file <a href="#od_ae33bced" id="od_ae33bced"></a>

#### **List file format**

You need to provide a text file with all your images for the warm-up (one URL per line):

```none
/sample.li/logo-cloudimg-black.png?w=200
/sample.li/logo-cloudimg-white.png?w=200
/sample.li/logo-cloudimg-yellow.png?w=200
/sample.li/hotel.jpg?pixellate=5
/sample.li/house.jpg?pixellate=5
/sample.li/eye.jpg?w=500&h=280
...
```

#### **Request**

```sh
curl --location --request POST 'https://warmup.api.cloudimage.com/warmup/urls' \
--header 'X-Client-Key: client_XXXXXXXXXXXXXXX' \
--form 'file=@url_list.csv'
```

`X-Client-Key` is the client's API key (can be found in Admin Console left menu : Settings / CDN Invalidation).

#### **Response**

```json
{
    "status": "success",
    "count_added": 4,
    "count_failed": 0,
    "msg": ""
}
```

### URL list in request body <a href="#od_5ff36124" id="od_5ff36124"></a>

#### **Request**

```sh
curl --location --request POST 'https://warmup.api.cloudimage.com/warmup/urls' \
--header 'X-Client-Key: client_XXXXXXXXXXXXXXX' \
--header 'Content-type: application/json' \
--data-raw '{"data": ["/sample.li/logo-cloudimg-black.png?w=200", "/sample.li/logo-cloudimg-white.png?w=200", "/sample.li/logo-cloudimg-yellow.png?w=200"]}'
```

`X-Client-Key` is the client's API key (can be found in Admin Console left menu : Settings / CDN Invalidation).

#### **Response**

```json
{
    "status": "success",
    "count_added": 4,
    "count_failed": 0,
    "msg": ""
}
```

You can check the status of the warm-up tasks for the last 5 days.

```
GET https://warmup.api.cloudimage.com/warmup/stats
```

#### Request <a href="#od_ccd0466f" id="od_ccd0466f"></a>
