Logic Apps Standard, frequent polling, HTTP and costs

Veli-Jussi Raitila 376 Reputation points

Logic Apps Standard has reserved compute capacity (i.e. App Service Plan) for running workflows as well as a fixed cost component due to said compute.

Say, I have an aggressive recurrence trigger set to a 1 second interval. This will fire an outbound HTTP call in order to poll an API. Further assume the API can handle the load, but polling is otherwise my only option due to technical limitations.

Recurrence triggers are not supported for stateless workflows so I have to use a stateful one.

What type of costs are incurred from a workflow such as this? Have I understood correctly that in addition to the fixed instance cost I also still have to - at a minimum - pay for Standard Connector calls (60 x 60 x 24 = 86400 per day)? Or more accurately twice that amount accounting for both the schedule trigger and the HTTP call.

    Hello @Veli-Jussi Raitila - Thanks for reaching out and posting on the MS Q&A!

    The following is stated about billing for the Standard tier SKUs (W1/W2/W3):

    The Standard model includes an unlimited number of free built-in operations that your workflow can run.

    And it looks like both the Schedule trigger & HTTP operations are part of the Built-in operations in the Standard SKU:

    Based on the above & scenario you described, you should only incur costs associated with the specific hosting plan you chose: Pricing tiers in the Standard model

    I hope this is helpful, if you've any doubts or additional feedback, feel free to ask in the comments and I'd be happy to clarify.
