API Gateway Endpoint Policies

API Gateway supports specifying policies on endpoints. For BaaS, this is not enabled in the Admin portal, but instead it can be specified directly on the service.

Only a few policies are supported since most of the API Gateway policies can be applied through code instead.

The following policies are currently supported:

• Quota
• Throttling
• CacheResponse

See the API Gateway documentation for more information on how the policies are configured. Documentation can be found here: https://docs.infor.com/en-us/inforos/. Open the "Infor OS User and Documentation Library". Then go to: Admininistrator -> API Gateway -> Policies.

Examples

Policies are added like this to the "restHandler" in the manifest:

```json
"policies": {
	"quota": {
	},
	"throttling": {
	},
	"cacheResponse": {
	}
}
```

```json
"quota": {
	"userLevel": false,
	"interval": 60,
	"timeUnit": "second",
	"allow": 1000
}
```

```json
"throttling": {
	"timePeriodInMilliseconds": 60000,
	"rateSmoothing.delayAfterCount": 1000,
	"rateSmoothing.delayFactorInMilliseconds": 1000,
	"spikeArrest.maxRequestsPerPeriod": 1000
}
```

```json
"cacheResponse": {
	"userLevel": false,
	"cacheKey.prefix": "myPrefix",
	"cacheKey.keyFragment": "myFragment",
	"cacheKey.keyFragment.ref": [
		"request.queryparam.EXAMPLE1",
		"request.queryparam.EXAMPLE2"
	],
	"expireSettings.timeoutInSeconds": 3600
}
```
