How can I fetch report data using API?

When you need to get raw data from a report via API, you can use an API call definition and ask directly the database for information.

To fetch data directly from a report, follow these steps:

1. Go to Menu > Analytics.
2. Navigate to Reports, Custom reports, Goals, or Ecommerce .
3. On the left, click a report that you want to work with.
4. Click the three-dot icon next to the report section that you want to use.
   

   

5. Click View API call definition.
   

   

6. Here’s your API endpoint and API query.
   

   

7. Prepare your Client ID and Client secret (Where to find it?)
8. Send the first call to get your access token. Our API uses a bearer token to authenticate each call.

   curl -X POST 'https://<account-name>.piwik.pro/auth/token' -H "Content-Type: application/json" --data '{
       "grant_type": "client_credentials",
       "client_id": "<client-id>",
       "client_secret": "<client-secret>"
   }'

   Change in this code:

   • <account-name>: Use your account name.
   • <client-id>: Use your client ID. (Where to find it?)
   • <client-secret>: Use your client secret. (Where to find it?)

   Response example:

   {
       "token_type": "Bearer",
       "expires_in": 1800,
       "access_token": "<bearer-token>"
   }

9. Copy your bearer token. And then make a second call that will fetch the data.

   curl -X POST 'https://<account-name>.piwik.pro/api/analytics/v1/query/' -H "Authorization: Bearer <bearer-token>" \
   -H "Content-Type: application/vnd.api+json" --data '{
     {
   	"date_from": "2022-07-01",
   	"date_to": "2022-09-30",
   	"website_id": "<site-or-app-id>",
   	"offset": 0,
   	"limit": 10,
   	"columns": [
   		{
   			"column_id": "referrer_type"
   		},
   		{
   			"column_id": "source_medium"
   		},
   		{
   			"column_id": "visitors"
   		},
   		{
   			"column_id": "sessions"
   		},
   		{
   			"column_id": "bounce_rate"
   		},
   		{
   			"column_id": "goal_conversions"
   		},
   		{
   			"column_id": "goal_conversion_rate"
   		},
   		{
   			"transformation_id": "sum",
   			"column_id": "goal_revenue"
   		}
   	],
   	"order_by": [
   		[
   			2,
   			"desc"
   		]
   	],
   	"filters": null,
   	"metric_filters": null
   }'

   In this code, change the following:

   • <account-name>: Use your account name.
   • <bearer-token>: Use the bearer token from the previous call. Each token is valid for 30 minutes only.
   • API query: Change the content of your API query to the one from step 6 (API call definition). You can also modify it.
