Logic Apps pricing model

You can create and run automated scalable integration workflows in the cloud with Azure Logic Apps. Here are the details about how billing and pricing work for Logic Apps.

Consumption pricing model

With newly created logic apps, you pay only for what you use. New logic apps use a consumption plan and pricing model, which means that all the action executions performed by a logic app instance are metered. Every step in a logic app definition is an action, which includes triggers, control flow steps, calls to built-in actions, and calls to connectors. For more information, see Logic Apps Pricing.

Triggers

Triggers are special actions that create a logic app instance when a specific event happens. Triggers act in different ways, which affect how the logic app is metered.

  • Polling trigger – This trigger continually checks an endpoint for messages that satisfy the criteria for creating a logic app instance and starting the workflow. Each polling request counts as an execution and is metered, even when no logic app instance is created. To specify the polling interval, set up the trigger through the Logic App Designer.

    To estimate more accurate consumption costs, consider the possible number of messages or events that might arrive on any given day, rather than base your calculations on only the polling interval. When an event or message meets the trigger criteria, many triggers immediately try to read any and all other waiting events or messages that meet the criteria. This behavior means that even when you select a longer polling interval, the trigger fires based on the number of waiting events or messages that qualify for starting workflows. Triggers that follow this behavior include Azure Service Bus and Azure Event Hub.

    So, for example, suppose you set up trigger that checks an endpoint every day. When the trigger checks the endpoint and finds 15 events that meet the criteria, the trigger fires and runs the corresponding workflow 15 times. Logic Apps meters all the actions that those 15 workflows perform, including the trigger requests. To calculate your potential costs, try the Azure pricing calculator.

  • Webhook trigger – This trigger waits for a client to send a request to a specific endpoint. Each request sent to the webhook endpoint counts as an action execution. For example, the Request and HTTP Webhook trigger are both webhook triggers.

  • Recurrence trigger – This trigger creates a logic app instance based on the recurrence interval that you set up in the trigger. For example, you can set up a recurrence trigger that runs every three days or on a more complex schedule.

You can find trigger executions in your logic app's Overview pane under the Trigger History section.

Actions

Built-in actions, such as actions that call HTTP, Azure Functions, or API Management, and also control flow steps are metered as native actions, which have their respective types. Actions that call connectors have the "ApiConnection" type. These connectors are classified as standard or enterprise connectors, which are metered based on their respective pricing.

All successfully and unsuccessfully run actions are counted and metered as action executions. However, actions that are skipped, due to unmet conditions, or actions that don't run, because the logic app terminated before completion, don't count as action executions. Disabled logic apps can't instantiate new instances, so they aren't charged while they are disabled.

Note

After you disable a logic app, any currently running instances might take some time before they completely stop.

Actions that run inside loops are counted per each cycle in the loop. For example, a single action in a "for each" loop that processes a 10-item list is counted by multiplying the number of list items (10) by the number of actions in the loop (1) plus one for starting the loop. So, for this example, the calculation is (10 * 1) + 1, which results in 11 action executions.

Integration Account usage

Consumption-based usage includes an integration account where you can explore, develop, and test the B2B/EDI and XML processing features in Logic Apps at no additional cost. You can have one integration account per region and store up to specific numbers of artifacts, such as EDI trading partners and agreements, maps, schemas, assemblies, certificates, and batch configurations.

Logic Apps also offers basic and standard integration accounts with supported Logic Apps SLA. You can use basic integration accounts when you either want to use only message handling, or act as a small business partner that has a trading partner relationship with a larger business entity. Standard integration accounts support more complex B2B relationships and increase the number of entities that you can manage. For more information, see Azure pricing.
