Using Application Integration in Free Tier is subject to the certain usage limitations.\n\nSee [Application Integration Free Tier](/application-integration/docs/pricing#free_use) for more information.\n\n### Does Application Integration have an API?\n\nYes, Application Integration has a set of RESTful APIs that allow you to programmatically create, update, delete, and manage your integrations.\n\nSee [Application Integration API](/application-integration/docs/reference/rest) for more information.\n\nIntegrations\n------------\n\n### How many integrations can I create in my Google Cloud project?\n\nA maximum of 1000 integrations can be created in a Google Cloud project.\n\nSee [Application Integration usage limits](/application-integration/docs/quotas#usage-limits) for more information.\n\n### Can I run more than one integration at a time?\n\nYes, See [Application Integration resource quotas](/application-integration/docs/quotas#resource-quotas) for more details.\n\n### Can I only create an integration in the region which was used during Application Integration setup?\n\nNot necessarily, Application Integration lets you provision or add new regions after you have set it up in your Google Cloud project. For information on the supported locations, see [Application Integration locations](/application-integration/docs/locations).\n\n### Does each integration version count as an individual integration?\n\nNo, an integration version is the structure or state of the integration and its tasks or triggers at a specific point in time. You can have up to 100 versions of an integration.\n\nFor more information about integration versions, see [Integration versions](/application-integration/docs/integration-versions).\n\n### How do I recover a deleted integration?\n\nRecovering a deleted integration is currently not supported in Application Integration.\n\n### What should I do if my integration flow is failing with errors?\n\nIn Application Integration, errors might occur when you are testing and publishing an integration, or during the execution of an integration. These errors can occur due to various client-side and server-side issues. Application Integration offers multiple error handling methods to respond and recover from the errors that are encountered when creating, testing, publishing, or running your integrations. You can use [error handling methods](/application-integration/docs/error-handling) for both synchronous and asynchronous modes of integration execution.\nIn Application Integration, errors might occur when you are testing and publishing an integration, or during the execution of an integration. To learn how to handle errors, see [Error handling](/application-integration/docs/error-handling).\n\n\u003cbr /\u003e\n\nPricing\n-------\n\nApplication Integration uses the pay-as-you-go pricing model where you only pay for what you use beyond the monthly Google Free Tier usage limitations.\n\n\nPricing for Application Integration is calculated on a monthly basis. It's based on the number of integration executions or metered execution count, the amount of data processed, and the number of connection nodes used.\n\nFor more information, see [Application Integration pricing](/application-integration/docs/pricing#payg).\n\n### Am I charged for using other Google Cloud resources in Application Integration?\n\nYes, running an integration in Application Integration incurs charges for other Google Cloud resources used in the integration, such as Integration Connectors, Secret Manager, and Cloud Key Management Service. Each item is stated separately in your bill, so you know exactly how your costs are calculated and allocated.\n\n### Is there a daily limit for the number of integrations that can be created during the public preview release?\n\nSee Application Integration [quotas and limits](/application-integration/docs/quotas) for details.\n\nIntegration Connectors\n----------------------\n\n### What are Integration Connectors?\n\nIntegration Connectors let you connect to various data sources from your integrations. With connectors, both Google Cloud services and other business applications are exposed to your integrations through a transparent, standard interface. As an integration developer, you can quickly connect to a growing pool of applications and systems without the need for protocol-specific knowledge or the use of custom code.\n\nFor more information, see [Integration Connectors overview](/integration-connectors/docs/about-connectors).\n\n### Should I set up and provision Integration Connectors independently of Application Integration?\n\nNo, Integration Connectors is automatically provisioned in your Google Cloud project when you set up Application Integration.\n\n### Will I be billed separately for use of Integration Connectors in Application Integration?\n\nYes, you will be billed separately for using Integration Connectors. Pricing for the connection nodes vary depending on the type of connectors used.\n\nIf you use connectors for Google services, the first two connection nodes are free. Each subsequent connection node is charged at $0.35 per hour. If you use connectors for non-Google services, then you're charged at a flat rate of $0.70 per hour per connection node.\n\nFor more information about the Integration Connectors pricing, see [Integration Connectors pricing](/integration-connectors/docs/pricing#pricing-for-connection-nodes)."]]
