Limits and configuration information for Azure Logic Apps

This article describes the limits and configuration details for creating and running automated workflows with Azure Logic Apps. For Microsoft Flow, see Limits and configuration in Microsoft Flow.

Definition limits

Here are the limits for a single logic app definition:

Name Limit Notes
Actions per workflow 500 To extend this limit, you can add nested workflows as needed.
Allowed nesting depth for actions 8 To extend this limit, you can add nested workflows as needed.
Workflows per region per subscription 1,000
Triggers per workflow 10 When working in code view, not the designer
Switch scope cases limit 25
Variables per workflow 250
Characters per expression 8,192
Maximum size for trackedProperties 16,000 characters
Name for action or trigger 80 characters
Length of description 256 characters
Maximum parameters 50
Maximum outputs 10

Run duration and retention limits

Here are the limits for a single logic app run:

Name Multi-tenant limit Integration service environment limit Notes
Run duration 90 days 365 days To change the default limit, see change run duration.
Storage retention 90 days from the run's start time 365 days To change the default limit, see change storage retention.
Minimum recurrence interval 1 second 1 second
Maximum recurrence interval 500 days 500 days

Change run duration and storage retention

To change the default limit for run duration and storage retention, follow these steps. If you need to go above the maximum limit, contact the Logic Apps team for help with your requirements.

  1. In the Azure portal, on your logic app's menu, choose Workflow settings.

  2. Under Runtime options, from the Run history retention in days list, choose Custom.

  3. Enter or drag the slider for the number of days you want.

Concurrency, looping, and debatching limits

Here are the limits for a single logic app run:

Name Limit Notes
Trigger concurrency * Unlimited when the concurrency control is turned off

* 25 is the default limit when the concurrency control is turned on, which can't be undone after you turn on the control. You can change the default to a value between 1 and 50 inclusively.

This limit describes the highest number of logic app instances that can run at the same time, or in parallel.

To change the default limit to a value between 1 and 50 inclusively, see Change trigger concurrency limit or Trigger instances sequentially.

Maximum waiting runs When the concurrency control is turned on, the minimum number of waiting runs is 10 plus the number of concurrent runs (trigger concurrency). You can change the maximum number up to 100 inclusively. This limit describes the highest number of logic app instances that can wait to run when your logic app is already running the maximum concurrent instances.

To change the default limit, see Change waiting runs limit.

Foreach array items 100,000 This limit describes the highest number of array items that a "for each" loop can process.

To filter larger arrays, you can use the query action.

Foreach concurrency 20 is the default limit when the concurrency control is turned off. You can change the default to a value between 1 and 50 inclusively. This limit is highest number of "for each" loop iterations that can run at the same time, or in parallel.

To change the default limit to a value between 1 and 50 inclusively, see Change "for each" concurrency limit or Run "for each" loops sequentially.

SplitOn items 100,000 For triggers that return an array, you can specify an expression that uses a 'SplitOn' property that splits or debatches array items into multiple workflow instances for processing, rather than use a "Foreach" loop. This expression references the array to use for creating and running a workflow instance for each array item.
Until iterations 5,000

Throughput limits

Here are the limits for a single logic app run:

Multi-tenant Logic Apps service

Name Limit Notes
Action: Executions per 5 minutes 100,000 is the default limit, but 300,000 is the maximum limit. To change the default limit, see Run your logic app in "high throughput" mode, which is in preview. Or, you can distribute the workload across more than one logic app as necessary.
Action: Concurrent outgoing calls ~2,500 You can reduce the number of concurrent requests or reduce the duration as necessary.
Runtime endpoint: Concurrent incoming calls ~1,000 You can reduce the number of concurrent requests or reduce the duration as necessary.
Runtime endpoint: Read calls per 5 minutes 60,000 You can distribute workload across more than one app as necessary.
Runtime endpoint: Invoke calls per 5 minutes 45,000 You can distribute workload across more than one app as necessary.
Content throughput per 5 minutes 600 MB You can distribute workload across more than one app as necessary.

Integration service environment (ISE)

Name Limit Notes
Base unit execution limit System-throttled when infrastructure capacity reaches 80% Provides ~4,000 action executions per minute, which is ~160 million action executions per month
Scale unit execution limit System-throttled when infrastructure capacity reaches 80% Each scale unit can provide ~2,000 additional action executions per minute, which is ~80 million more action executions per month
Maximum scale units that you can add 10

To go above these limits in normal processing, or run load testing that might go above these limits, contact the Logic Apps team for help with your requirements.

HTTP limits

Here are the limits for a single HTTP request or synchronous connector call:

Timeout

Some connector operations make asynchronous calls or listen for webhook requests, so the timeout for these operations might be longer than these limits. For more information, see the technical details for the specific connector and also Workflow triggers and actions.

Name Multi-tenant limit Integration service environment limit Notes
Outgoing request 120 seconds 240 seconds For longer running operations, use an asynchronous polling pattern or an until loop.
Synchronous response 120 seconds 240 seconds For the original request to get the response, all steps in the response must finish within the limit unless you call another logic app as a nested workflow. For more information, see Call, trigger, or nest logic apps.

Message size

Name Multi-tenant limit Integration service environment limit Notes
Message size 100 MB 200 MB To work around this limit, see Handle large messages with chunking. However, some connectors and APIs might not support chunking or even the default limit.
Message size with chunking 1 GB 5 GB This limit applies to actions that natively support chunking or let you enable chunking in their runtime configuration.

For the integration service environment, the Logic Apps engine supports this limit, but connectors have their own chunking limits up to the engine limit, for example, see Azure Blob Storage connector. For more information chunking, see Handle large messages with chunking.

Expression evaluation limit 131,072 characters 131,072 characters The @concat(), @base64(), @string() expressions can't be longer than this limit.

Retry policy

Name Limit Notes
Retry attempts 90 The default is 4. To change the default, use the retry policy parameter.
Retry max delay 1 day To change the default, use the retry policy parameter.
Retry min delay 5 seconds To change the default, use the retry policy parameter.

Custom connector limits

Here are the limits for custom connectors that you can create from web APIs.

Name Multi-tenant limit Integration service environment limit Notes
Number of custom connectors 1,000 per Azure subscription 1,000 per Azure subscription
Number of requests per minute for a custom connector 500 requests per minute per connection 2,000 requests per minute per custom connector

Managed identities

Name Limit
Number of logic apps with system-assigned managed identities per Azure subscription 100

Integration account limits

Artifact limits per integration account

Here are the limits on the number of artifacts for each integration account. For more information, see Logic Apps pricing.

Map (XSLT file) 8 MB To upload files larger than 2 MB, use the Azure Logic Apps REST API - Maps.
Schema 8 MB To upload files larger than 2 MB, use an Azure storage account and blob container.
Runtime endpoint Limit Notes
Read calls per 5 minutes 60,000 You can distribute the workload across more than one account as necessary.
Invoke calls per 5 minutes 45,000 You can distribute the workload across more than one account as necessary.
Tracking calls per 5 minutes 45,000 You can distribute the workload across more than one account as necessary.
Blocking concurrent calls ~1,000 You can reduce the number of concurrent requests or reduce the duration as necessary.

B2B protocol (AS2, X12, EDIFACT) message size

Here are the message size limits that apply to B2B protocols:

Name Multi-tenant limit Integration service environment limit Notes
AS2 v2 - 100 MB
v1 - 50 MB
v2 - 200 MB
v1 - 50 MB
Applies to decode and encode
X12 50 MB 50 MB Applies to decode and encode
EDIFACT 50 MB 50 MB Applies to decode and encode

Disabling or deleting logic apps

When you disable a logic app, no new runs are instantiated. All in-progress and pending runs continue until they finish, which might take time to complete.

When you delete a logic app, no new runs are instantiated. All in-progress and pending runs are canceled. If you have thousands of runs, cancellation might take significant time to complete.

Firewall configuration: IP addresses

All logic apps in the same region use the same IP address ranges. To support the calls that your logic apps directly make with HTTP, HTTP + Swagger, and other HTTP requests, set up your firewalls with all the inbound and outbound IP addresses used by the Logic Apps service, based on the regions where your logic apps exist. These addresses appear under the Inbound and Outbound headings in this section, and are sorted by region.

To support the calls that Microsoft-managed connectors make, set up your firewall with all the outbound IP addresses used by these connectors, based on the regions where your logic apps exist. These addresses appear under the Outbound heading in this section, and are sorted by region.

For Azure Government and Azure China 21Vianet, reserved IP addresses for connectors aren't currently available.

Important

If you have existing configurations, please update them as soon as possible before September 1, 2018 so they include and match the IP addresses in these lists for the regions where your logic apps exist.

Logic Apps doesn't support directly connecting to Azure storage accounts through firewalls. To access these storage accounts, use either option here:
