A **task** is a unit of measure in Onlizer that allows you to estimate how many resources the integration uses.

**For example**, if the integration to transfer a request from a site to CRM works once, two tasks are spent.

We receive an average of 500 requests per month - 500 * 2 tasks = 1,000 tasks per month.

### It is now possible to calculate how many tasks will be needed to ensure the volume of requests and to select the appropriate fare.

**How is the cost of integration calculated for one launch?**

The tasks spent are calculated on the basis of integration steps or seconds of integration.

**For example, integration consists of four steps:**

1. Timed integration every hour.

2. Export data from CRM.

3. Formatting the letter text.

4. Send mail via Gmail.

This process consists of **4 steps,** and it runs for three seconds — this integration costs **4 tasks**.

But if integration is 4 steps, but it takes **7 seconds**, then it costs **7 tasks**.

As you can see from the examples above, **the cost of integration is estimated at a higher value of steps or seconds.**

**How do you see how many tasks integration costs per execution?**

Need to go to **Project **— **Runs History**.
