The task iterates over the configured array variable and calls\nthe sub-integration for each element in the array. The number of times\nthe sub-integration is called is equal to the size of the array variable.\n\nThe **API Trigger ID** and the **Integration name** identifies the sub-integration you\nwant to run.\n\nThe task also lets you collect the response from each sub-integration run and store the value in your\ncurrent integration for use in downstream tasks. You can use any of the following approach to collect the responses:\n\n- Collate the response of each run in an array variable, where each element of the array has the response from one particular run. To collate the responses, configure the `Collect values from sub-integration output(s)` property.\n- Aggregate the responses of all the runs in a single variable. To aggregate the responses, configure the `Response parameter override mapping` property.\n\n| **Note** :\n|\n| - A **For Each Loop** task can run a maximum of 8000 iterations.\n| - The cumulative size of the data collected from each sub-integration run cannot exceed `50 MB`. If the size exceeds `50 MB`, the integration fails, and the downstream tasks are not run.\n| - If an integration in the **For Each Loop** task fails, then the entire task fails, and the downstream tasks are not run. To prevent failure of the entire integration you can specify an **Execution strategy** for the task in its *Join configuration pane* . See [Join](/application-integration/docs/forks-joins#join) for more details.\n\nBefore you begin\n----------------\n\n- Ensure that you have [attached a user-managed service account](/application-integration/docs/access-control#add-service-account) to your integration. If your integration does not have user-managed service account configured, then by default the [default service account](/application-integration/docs/access-control#default-service-account) (`service-`\u003cvar translate=\"no\"\u003ePROJECT_NUMBER\u003c/var\u003e`@gcp-sa-integrations.iam.gserviceaccount.com`) is used for authentication.\n- Ensure that your service account has the **Application Integration Invoker** IAM role. For information about granting roles to a service account, see [Manage access to service accounts](/iam/docs/manage-access-service-accounts).\n\nConfiguration properties\n------------------------\n\n\nThe following table describes the configuration properties of the **For Each Loop** task.\n\nBest practices\n--------------\n\nFor information about the usage limits that apply to the **For Each Loop** task, see [Usage limits](/application-integration/docs/quotas#usage-limits).\n\nError handling strategy\n-----------------------\n\n\nAn error handling strategy for a task specifies the action to take if the task fails due to a [temporary error](/application-integration/docs/error-handling). For information about how to use an error handling strategy, and to know about the different types of error handling strategies, see [Error handling strategies](/application-integration/docs/error-handling-strategy).\n\nQuotas and limits\n-----------------\n\nFor information about quotas and limits, see [Quotas and limits](/application-integration/docs/quotas).\n\nWhat's next\n-----------\n\n- Learn about [all tasks and triggers](/application-integration/docs/all-triggers-tasks).\n- Learn how to [test and publish an integration](/application-integration/docs/test-publish-integrations).\n\n- Learn about [error handling](/application-integration/docs/error-handling-strategy).\n- Learn about [integration execution logs](/application-integration/docs/introduction-logs)."]]
