Data connector alerts notify you when there are problems getting your data from your partner networks.

Singular pulls your data every day from your partner networks. We aim to make all of yesterday's data available every morning by 8 a.m. local time (see Data Freshness and Update Times). Occasionally, some data is not available by that time, either because of technical issues on the network's side, problems logging into the network, or a number of other reasons.

You can sign up for two types of data connector alerts:

• Data delays: General notification whenever data for a particular network is not available at the appointed time. Sign up for this alert if you need to know when data is missing.

  This alert is also available via Slack.

• Login issues: Occasionally, a partner network can't be accessed because of an authentication problem. Sign up for this alert if you're authorized to go into Singular and reauthenticate or reenter your organization's credentials for ad networks.

In some cases, a data delay requires your action (e.g., to provide updated credentials). If so, Singular specifies what you need to do.

But in most cases, if there's a data delay, Singular is already retrying the data pull automatically, and/or the Singular team is investigating the issue. When possible, we give an estimate of when the data will be available by. All you need to do is check back to the Data Connectors page for the status update.

Singular can send you a daily update on Slack showing if any of your data connectors are experiencing delays, as well as if any of them require action on your part. You can receive the notification as a direct message or to a Slack channel.

To sign up for Slack data delay alerts:

1. In the Alerts page, hover over "Data Connector Alerts" and click the edit icon.
2. Click Activate Data Delay alerts on Slack.

To set this up, go to Settings > Data Connectors and click Alert me on Slack:

You can always go to Settings > Data Connectors to see the updated status of your data connectors.

If there was an unknown problem pulling the data, but Singular has since found the source of the issue, the page will be updated with more details and an estimate of when the data should become available.

You can also see when data was last pulled from that network and when the next pull is scheduled.

Learn more in the Data Connectors FAQ.

Custom alerts are automatic notifications you can set up to monitor your data for significant changes or unexpected stats. You can set up alerts with absolute conditions ("Alert me when daily revenue reaches $20,000") or relative conditions ("Alert me if installs decrease by 20%").

When you first visit the Alerts page, you may see an alert called "Default Fraud Alerts".

Singular creates this default alert to get you started. This alert emails all admin users when there is an increase of rejected installs by 10% in the last 7 days. You may safely edit or discard the alert.

Some popular use cases for custom alerts are:

• Monitoring CPI spikes: Be informed of ad network CPI changes to keep your ad spend in check ("Alert me if the CPI on any network increases by 20% day-over-day")
• Shifts in ROI: Know when specific networks are under- or overperforming to reallocate your budgets proactively ("Alert me if network A's 7-days-over-7-days ROI decreases by 10%")
• Overspend warnings: Set weekly thresholds to be alerted when specific dimensions have exceeded the budgeted amount ("Alert me if the past 7-days spend for network B in Germany or US exceeds $5K")

To set up a custom alert, go to Automation > Alerts and click Add new alert. Follow the on-screen instructions. For a detailed step-by-step guide, see How to Set Up a Custom Alert.

When you configure an alert, you first have to choose the type of data (the type of report) you want to be alerted on, and then you can select the specific metric you want to monitor from that report. The available options depend on your account configuration.

There are several time periods you can compare when you set up a relative condition:

If you set an alert for a relative change in a metric (e.g., "clicks rise by over 20%"), you run the risk of getting useless alerts based on very small numbers (e.g., when clicks rise from 2 to 3).

To prevent this, you can add a threshold in absolute numbers. The threshold can be based on any metric but it always applies to the same period of time you defined in the rule.

For more details, see How to Set Up a Custom Alert.

The threshold is calculated based on the same time period as the condition. For more details, see How to Set Up a Custom Alert.

A custom alert is sent to all users specified in the alert definition, plus users who have opted to subscribe to an alert from the Alerts Summary page (even if they are not Singular users.

When you define an alert, if you include a recipient email that is not in the domain of your account (your organization), you see a warning. 

Recipients can choose to unsubscribe.

The data is checked daily at 8 a.m. to trigger any alerts that apply. If you need the check to run at a different time of day, contact Singular support.

If the data for any source (network) involved in an alert definition is delayed, the alert is still triggered based on the data that is available at the time. Singular will let you know in the alert email if any sources are missing.

When alerts are triggered, recipients are notified as soon as possible, with the exception of alerts based on mail reports. With mail reports, recipients are notified within 24 hours (i.e., by the following morning).

Every alert email includes an unsubscribe link. You can also log into Singular, go to the Alerts page and unsubscribe.

Any user with access to the organization's Singular account can modify, enable/disable or delete the account's alerts. Users who are subscribed to the alert receive an email notifying them of the modification or cancellation of the alert.

For more information about managing users and permissions in your Singular account, see Team Management.

To remove a recipient from an alert, go to Automation > Alerts, click the Edit icon for the alert, and remove users as desired. If you remove anyone other than yourself, the person will receive an email to let them know they were removed from the alert list.
