Work with the Throttling API

The Throttling API helps you create, configure and monitor your throttling configurations in order to limit the number of events sent per second.

This section provides global information on how to work with the API. A detailed API description is available in Adobe Journey Optimizer APIs documentation.

IMPORTANT

Only one configuration is currently allowed per organisation. A configuration must be defined on a production sandbox (given through x-sandbox-name in the headers).

A configuration is applied at organization level.

When the limit set in the API is reached, further events are queued for up to 6 hours. This value cannot be modified.

Throttling API description

Method Path Description
POST list/throttlingConfigs Get a list of the throttling configurations
POST /throttlingConfigs Create a throttling configuration
POST /throttlingConfigs/{uid}/deploy Deploy a throttling configuration
POST /throttlingConfigs/{uid}/undeploy Undeploy a throttling configuration
POST /throttlingConfigs/{uid}/canDeploy Check if a throttling configuration can be deployed or not
PUT /throttlingConfigs/{uid} Update a throttling configuration
GET /throttlingConfigs/{uid} Retrieve a throttling configuration
DELETE /throttlingConfigs/{uid} Delete a throttling configuration

Throttling configuration 

Here is the structure of a throttling configuration. name and description attributes are optional.

{
    "name": "<given name - free text>",
    "description": "<given description - free text>"
    "urlPattern": "<endpoint URL - wildcards are allowed>",
    "methods": [ "<HTTP method such as GET, POST, PUT>" ],
    "maxThroughput": <max call throughput>
}

Example:

{
  "name": "throttling-config-external",
  "description": "example of throttling config for an external endpoint",
  "urlPattern": "https://api.example.org/data/2.5/*",
  "methods": ["POST", "PUT"],
  "maxThroughput": 4000
}

Errors

When creating or updating a configuration, the process validates the given configuration and returns the validation status identified by its Unique ID, either:


"ok" or "error"
IMPORTANT

The attributes maxThroughput, urlPattern and methods are mandatory.

maxThroughput value must be in 200-5000 range.

When creating, deleting or deploying throttling configuration, the following errors can occur :

  • ERR_THROTTLING_CONFIG_100: throttling config: <mandatory attribute> required
  • ERR_THROTTLING_CONFIG_101: throttling config: maxThroughput is required and must be greater than or equal to 200 and less than or equal to 5000
  • ERR_THROTTLING_CONFIG_104: throttling config: malformed url pattern
  • ERR_THROTTLING_CONFIG_105: throttling config: wildcards not allowed in host part of the url pattern
  • ERR_THROTTLING_CONFIG_106: throttling config: invalid payload
  • THROTTLING_CONFIG_DELETE_FORBIDDEN_ERROR: 1456, “Can’t delete a deployed throttling config. Undeploy it before deleting it”
  • THROTTLING_CONFIG_DELETE_ERROR: 1457, “Can’t delete throttling config: unexpected error occurs”
  • THROTTLING_CONFIG_DEPLOY_ERROR: 1458, “Can’t deploy throttling config: unexpected error occurs”
  • THROTTLING_CONFIG_UNDEPLOY_ERROR: 1459, “Can’t undeploy throttling config: unexpected error occurs”
  • THROTTLING_CONFIG_GET_ERROR: 1460, “Can’t get throttling config: unexpected error occurs”
  • THROTTLING_CONFIG_UPDATE_NOT_ACTIVE_ERROR: 1461, “Can’t update throttling config: runtime version is not active”
  • THROTTLING_CONFIG_UPDATE_ERROR: 1462, “Can’t update throttling config: unexpected error occurs”
  • THROTTLING_CONFIG_NON_PROD_SANDBOX_ERROR: 1463, “Operation not allowed on throttling config: non prod sandbox”
  • THROTTLING_CONFIG_CREATE_ERROR: 1464, “Can’t create throttling config: unexpected error occurs”
  • THROTTLING_CONFIG_CREATE_LIMIT_ERROR: 1465, “Can’t create throttling config: only one config allowed per org”
  • THROTTLING_CONFIG_ALREADY_DEPLOYED_ERROR: 14466, “Can’t deploy throttling config: already deployed”
  • THROTTLING_CONFIG_NOT_FOUND_ERROR: 14467, “throttling config not found”
  • THROTTLING_CONFIG_NOT_DEPLOYED_ERROR: 14468, “Can’t undeploy throttling config: not deployed yet”

Errors examples

When trying to create a config on non-prod sandbox:

{
    "status": 400,
    "error": "{\"code\":1463,\"family\":\"INPUT_OUTPUT_ERROR\",\"message\":\"Operation not allowed on throttling config: non prod sandbox\",\"service\":\"vyg-authoring-api\",\"version\":\"ed87515\",\"context\":\"com.adobe.voyager.service.authoring.restapis.v1_0.ThrottlingConfigService:384\",\"schema\":\"throttlingConfigs$ui-tests\"}",
    "requestId": "5sgnAYXs8mpswwjAFEIaAU2faQYbtyHc"
}

In case given sanbox does not exist:

{
    "status": 500,
    "error": "{\"code\":4000,\"family\":\"INTERNAL_ERROR\",\"message\":\"INTERNAL ERROR\",\"service\":\"vyg-authoring-api\",\"version\":\"ed87515\",\"context\":\"com.adobe.voyager.common.exceptions.ApiErrorException:43\"}",
    "requestId": "04ZJ4e5ki4bYs3lfO17a7hovRGewjvdK"
}

When trying to create another config:

{
    "status": 400,
    "error": "{\"code\":1465,\"family\":\"INPUT_OUTPUT_ERROR\",\"message\":\"Can't create throttling config: only one config allowed per org\",\"service\":\"vyg-authoring-api\",\"version\":\"ed87515\",\"context\":\"com.adobe.voyager.service.authoring.restapis.v1_0.ThrottlingConfigService:108\",\"schema\":\"throttlingConfigs$prod\"}",
    "requestId": "A7ezT8JhOQT4WIAf1Fv7K2wCDA8281qM"
}

Use-cases

To help you in your testing and configuration, a Postman collection is available here.

This Postman Collection has been set up to share the Postman Variable collection generated via Adobe I/O Console’s Integrations > Try it out > Download for Postman, which generates a Postman Environment file with the selected integrations values.

Once downloaded and uploaded into Postman, you need to add three variables: {JO_HOST},{BASE_PATH} and {SANDBOX_NAME}.

  • {JO_HOST} : Journey Optimizer Gateway URL
  • {BASE_PATH} : entry point for the API.
  • {SANDBOX_NAME} : the header x-sandbox-name (for example, ‘prod’) corresponding to the sandbox name where the API operations will take place. See the sandboxes overview for more information.

In the following section, you will find the Rest API calls ordered list to perform the use-case.

Use-Case n°1: Creation and deployment of a new throttling configuration

  1. list
  2. create
  3. candeploy
  4. deploy

Use-Case n°2: Update and deploy a throttling configuration not deployed yet

  1. list
  2. get
  3. update
  4. candeploy
  5. deploy

Use-Case n°3: Undeploy and delete a deployed throttling configuration

  1. list
  2. undeploy
  3. delete

Use-Case n°4: Delete a deployed throttling configuration

In only one API call, you can undeploy and delete the configuration with the use of the forceDelete parameter.

  1. list
  2. delete, with forceDelete param

Use-Case n°5: Update a throttling configuration already deployed

NOTE

It is not required to undeploy the configuration before updating

  1. list
  2. get
  3. update

Configuration life-cycle at runtime level

When a configuration is undeployed, it is marked as inactive at runtime level and pending events continue to be processed during 24 hours. It is then deleted in the runtime service.

After a configuration has been undeployed, it is possible to update and redeploy the configuration. This will create a new runtime configuration that will be considered in the upcoming actions execution.

When updating a configuration already deployed, the new values are taken into account immediately. The underlying system resources are automatically adapted. This is optimal compared to undeploy then redeploy the configuration.
