We have two monitor types that consist of several actions that are executed as a sequence: Transactions and Multi-step API monitors. Longer sequences are more expensive to execute, so long transactions or MSA monitors require more space in your account. Until recently, if you needed more space for transactions, you could purchase additional transaction steps. Similarly, you could buy extra API steps for MSA monitors.
We haven’t actually changed this, but we’re giving it a better name. Why was this necessary? The actions in a transaction or MSA are organized in things also called Steps. However, these steps provide a logical separation into distinct chunks. There’s no cost involved in keeping things organized, so it was confusing that both the logical separation and the involved cost were using the word step.
Therefore, the new naming convention is: logical steps are still called Steps. Transactions and MSAs consist of several steps, but the cost of each step depends on what you put in them. The cost for each Transaction or MSA is now expressed in Credits. You’ll keep the same amount you had before, we’re just giving it a different name.
In your Monitor overview, Subscription settings and new Invoices, you’ll now see the terms Transaction credits and API credits.
