Creating a Plan

Software AG Products 10.11 | Using API Gateway | API Packages and Plans | Creating a Plan

Creating a Plan

You must have the API Gateway's manage packages and plans functional privilege assigned to perform this task.

An API Plan is the contract proposal presented to consumers who are about to subscribe to APIs. Plans are offered as tiered offerings with varying availability guarantees, SLAs or cost structures associated with them. An API package can be associated with multiple plans at a time. This helps the API providers in providing tiered access to their APIs to allow different service levels and pricing plans. Though you can edit or delete a plan that has subscribers, Software AG recommends you not to do so.

You can create packages and plans, associate a plan with a package, associate APIs with a package, view the list of packages, package details, and APIs and plans associated with the package in the API Gateway user interface.

You can create a plan from the Manage packages and plans page.

To create a plan

1. Click Packages in the title navigation bar.

2. Click Create in the Manage packages and plans section.

3. Select Plan.

4. Click Create.

5. Provide the following information in the Basic information section:

Field	Description

10. Click Save.

11. Click Pricing in the left navigation pane.

12. Provide the following information in the Pricing section:

Field	Description
Cost	Specifies the cost for the plan.
Terms	Specifies the terms of conditions for the pricing.
License	Specifies the license information.

You can save the plan at this point and provide traffic optimization configurations at a later time.

13. Click Continue to Quality of Service.

Alternatively, click Rate limits in the left navigation pane.

14. Click + Add Rule.

15. Provide the following information in the Create Rule section:

Field	Description
Maximum request count	Specifies the maximum number of requests handled. Value provided should be an integer.
Interval	Specifies the value for the interval for which the maximum request count is handled. Value provided should be an integer.
Interval unit	Specifies the unit of measurement of the time interval. For example: Minutes Hours Days Calendar Week. The plan starts on the first day of the week and ends on the last day of the week. By default, the start day of the week is set to Monday. For example: If you subscribe to a package on a Wednesday and Interval is set to 1, the validity of the plan ends on Sunday, that is, 5 days. If you subscribe to a package on a Wednesday and Interval is set to 2, the validity of the plan still ends on Sunday, but the validity of the plan is two calendar weeks, that is 12 days. You can change the start day of the week using the extended setting startDayOfTheWeek in the Administration > General > Extended settings section. Restart the API Gateway server for the changes to take effect. Calendar Month. Starts on the first day of the month and ends on the last day of the month. For example: If you subscribe to a package in the month of August and Interval is set to 1, the validity of the plan ends on the last day of August. If you subscribe to a package in the month of August and Interval is set to 2, the validity of the plan ends in two calendar months, that is on the last day of September.
Alert frequency	Specifies how frequently to send alerts to API Gateway destination when the Rate limits condition is violated. Select one of the options: Only Once. Triggers an alert only the first time one of the specified conditions is violated. Every Time. Triggers an alert every time one of the specified conditions is violated.
Violation message	Specifies the text that appears when the rule is violated.

16. Click Ok.

This creates the rule and displays it in the Configured rules table. Click + Add rule to add more rules. You can edit or delete the rules by clicking the Edit and the Delete icons respectively.

At a later time, when this plan is applied to an API through a package, the rules that you configured for this plan are enforced on the applied API.

17. Click Quota and provide the following information in the Quota settings section.

Field	Description
Maximum request quota	Specifies the maximum number of requests handled. Value provided should be an integer.
Block on breach	When selected, it specifies that the access to the API is blocked when there is a rule violation. Also, a notification is sent to API Gateway destination depending on the Alert frequency. By default, this option is not selected.
Interval	Specifies the value for the interval for which the maximum request quota is handled. Value provided should be an integer.
Interval unit	Specifies the unit of measurement of the time interval. For example: Minutes Hours Days Calendar Week. The plan starts on the first day of the week and ends on the last day of the week. By default, the start day of the week is set to Monday. For example: If you subscribe to a package on a Wednesday and Interval is set to 1, the validity of the plan ends on Sunday, that is, 5 days. If you subscribe to a package on a Wednesday and Interval is set to 2, the validity of the plan still ends on Sunday, but the validity of the plan is two calendar weeks, that is 12 days. You can change the start day of the week using the extended setting startDayOfTheWeek in the Administration > General > Extended settings section. Restart the API Gateway server for the changes to take effect. Calendar Month. Starts on the first day of the month and ends on the last day of the month. For example: If you subscribe to a package in the month of August and Interval is set to 1, the validity of the plan ends on the last day of August. If you subscribe to a package in the month of August and Interval is set to 2, the validity of the plan ends in two calendar months, that is on the last day of September.
Alert frequency	Specifies how frequently to send alerts to API Gateway destination when the Quota condition is violated. Select one of the options: Only Once. Triggers an alert only the first time one of the specified conditions is violated. Every Time. Triggers an alert every time one of the specified conditions is violated.
Violation message	Specifies the text that displays when the policy is violated.
Notification settings	Specifies whether notifications are to be sent on rule violations. Enable the toggle button to enable the notifications and provide the following information: Notify after (in %). Provide a value which is a number. A notification is sent to the configured email IDs once the total request count reaches the % value as provided in the maximum quota value. Violation message. Provide the content of the mail that is sent to the configured email Ids once the quota request count reaches the limit specified. Email Ids. Provide an email Id of the recipient to which notifications have to be sent once the quota request count reaches the limit specified. Click to add multiple recipients. Note: The SMTP settings under Administrator settings > Destinations has to be provided for an email to be sent. Send Digital Events Custom destination. Select custom destinations to which the notification must be sent. You can select multiple custom destinations. The custom destinations displayed in this field are populated from the custom destinations, configured in the Administration > Destinations > Custom destinations page.

Important:
Incase of a server crash or restart, the quota status is determined by the value set in the pgmen.quotaSurvival.addLostIntervals property and works as follows:

If the property is set to false, remaining time in quota is retained even after a restart or crash. For example, If quota is of 60 minutes and 7 minutes was used before the server crash or restart, then quota remaining time of 53 minutes is retained after server crash or restart, if the property is set to false.

If the property is set to true, and if the sum of time between server shutdown and restart and quota elapsed time does not exceed the interval of the subscription, the quota usage value is retained. In this case the remaining quota time is calculated as {current interval cycle - (elapsed time + (start time - shutdown time))}. For example, if the current subscription duration is 1 month and if the server starts on the 10th day of the cycle and restarts on the 12th day of the cycle, the remaining quota time is calculated as {30 - (10 + (12-10))} = 18 days.

If the property is set to true, and if the sum of time between server shutdown and restart and quota elapsed time exceeds the interval of the subscription, a new interval is created. Quota usage value is not retained in this case.

18. Click Save.

The plan is created and listed in the list of plans.
