Anypoint MQ REST APIs

The Anypoint MQ APIs enable you to use REST to send and receive messages, administer queues and message exchanges, and analyze results.

Anypoint MQ provides these APIs:

Anypoint MQ portals are available in the Developer portal.

Workflow for an API

The following example with the Broker API illustrates the workflow for accessing an API:

mq api workflow

Steps:

  1. An app sends a request to Anypoint MQ and sets how long to hold the lock on the message.

  2. Anypoint MQ sends the message and the lock ID.

  3. The app acknowledges the message and requests Anypoint MQ to delete the message, or the app negatively acknowledges the message and requests Anypoint MQ to make the message available to other apps. The app sends the message ID and lock ID to Anypoint MQ.

  4. If no action is taken and the duration of a lock’s time to live expires, the message is negatively acknowledged and returns to the queue to be available for other apps.

Authorize API Access

Before accessing an API, you need to acquire an access token:

The curl command for each is explained in the API sections.

Anypoint MQ Admin API

The Anypoint MQ Admin API provides access to Anypoint MQ administrative functionality.

You can use the Admin API to create and manage apps, queues, and message exchanges.

You can get the organization ID and environment ID in the payload.txt file that Anypoint Platform creates for any auditable action in MQ. See MQ Audit Logging.

You can get the access token from the Anypoint Platform user. The access token is also known as the Bearer. The access token has a default time to live (TTL) of 60 minutes.

You can use this curl command to get the access token:

curl -X POST -H "Content-Type: application/json" -d '{"username":"USERNAME", "password":"PASSWORD"}' https://anypoint.mulesoft.com/accounts/login

The command returns output similar to:

{
  "access_token": "42424242-4242-4242-4242-424242424242",
  "token_type": "bearer",
  "redirectUrl": "/home/"
}

In the Admin API portal, click Download to download the API as a RAML, Mule 3 zipped connector file, or as a Mule 4 connector JAR file.

mq rest admin portal

Create a FIFO Queue in the Admin API Portal

You can create a FIFO queue from the Admin API portal by including the "fifo": true field.

Note: The organization from which you use the Administration portal must have an Anypoint MQ FIFO entitlement. See Anypoint MQ FAQ for the regions where Anypoint MQ is available.

For the following path using the PUT operation:

/organizations/ORGANIZATION_ID/environments/ENVIRONMENT_ID/regions/REGION_ID/destinations/queues/QUEUE_ID

Use this body:

{
  "defaultTtl" : 120000,
  "defaultLockTtl" : 10000,
  "encrypted" : false,
  "fifo" : true
}

Anypoint MQ Broker API

The Anypoint MQ Broker API enables clients to send and receive messages from queues and exchanges.

You can get the organization ID and environment ID in the payload.txt file that Anypoint Platform creates for any auditable action in MQ. See MQ Audit Logging.

Getting the access (bearer) token requires using either a command like curl or an app like Postman. The example that follows uses curl. If you are a Windows user, you need to download a curl command before accessing the information.

The access token in this section can only be used with the Broker API. Do not use this access token with the Stats and Admin APIs.

To get the Broker API access token:

  1. Log in to Anypoint Platform.

  2. Click MQ > Client Apps, and then click the blue plus-circle icon to create an app.

  3. Get the client ID and client secret and use these values in the curl command below replacing CLIENT_ID and CLIENT_SECRET:

    curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d "client_id=CLIENT_ID&client_secret=CLIENT_SECRET&grant_type=client_credentials" "https://mq-us-east-1.anypoint.mulesoft.com/api/v1/authorize"

    See the Anypoint MQ FAQ for the regions where Anypoint MQ and FIFO are available.

  4. Submit the curl command.

    The command returns output similar to:

    {"access_token":"<token>","simple_client":{"envId":"ENVIRONMENT_ID","orgId":"ORGANIZATION_ID"},"token_type":"bearer"}

Broker API Portal - Publish, consume, ack, and nack messages between queues and message exchanges.

In the Broker API portal, click Download to download the API as a RAML, Mule 3 zipped connector file, or as a Mule 4 connector JAR file.

Anypoint MQ Stats API

The Anypoint MQ Stats API enables you to get statistics and metrics for queues and message exchanges.

You can use the Anypoint MQ Stats API to perform statistical analysis of queue performance.

Use the Stats API to retrieve:

  • Anypoint MQ metrics:

    • Real-time statistics for queues

    • Historical statistics for queues

    • Historical statistics for message exchanges

  • Usage metrics

    View your entire organization’s usage of Anypoint MQ for billing purposes: Usage per environment Usage per organization

  • Statistics for queues and message exchanges

  • Number of messages currently in a queue

For more information, see the Anypoint MQ Stats API in the MuleSoft developer portal.

Use the Anypoint MQ Stats API

To access the Anypoint MQ Stats API, you must first authenticate using the Anypoint Access Management API.

To use the Stats API, you can get the access token from the Anypoint Platform user. The access token is also known as the Bearer. The default time to live (TTL) for the access token is 60 minutes. You can get the organization ID and environment ID in the payload.txt file that Anypoint Platform creates for any auditable action in MQ. See MQ Audit Logging.

You can use this curl command to get the access token:

curl -X POST -H "Content-Type: application/json" -d '{"username":"USERNAME", "password":"PASSWORD"}' https://anypoint.mulesoft.com/accounts/login

This returns output similar to:

{
  "access_token": "42424242-4242-4242-4242-424242424242",
  "token_type": "bearer",
  "redirectUrl": "/home/"
}

In the Stats API portal, click Download to download the API as a RAML, Mule 3 zipped connector file, or as a Mule 4 connector JAR file.

mq rest stats portal

Real-Time Statistics for Queues

You can get an immediate snapshot of how many messages are in the queue and how many are in-flight (see Anypoint MQ Terminology for what in-flight messages are). This data is updated in almost real-time. The Statistics API can fetch real-time statistics for multiple queues and returns a comma-separated list.

/queues?destinationIds={queue1},{queue2}

Sample Request and Response:

https://anypoint.mulesoft.com/mq/stats/api/v1/organizations/ORGANIZATION_ID/environments/ENVIRONMENT_ID/regions/REGION_URL
/queues?destinationIds=DESTINATION_ID

[
  {
      "destination": "95bgpyxYsVyFE",
      "messages": 0,
      "inflightMessages": 0
  }
]

Historical Statistics for a Queue

This API can be used to fetch historical statistics for a queue, however, it does not get updated in real-time, and there is an approximate latency of 5 to 10 minutes before data is published. The retention period of historical data is 15 months. Also, to keep the volume of data under control, historical data is stored at reduced levels of granularity. Data points with a period of fewer than 60 seconds are available for 3 hours, one-minute data points are available for 15 days, five-minute data points for 63 days, and one-hour data points for 15 months.

/queues/{queueId}?startDate=…​&endDate=…​&period=…​

Sample Request and Response:

https://anypoint.mulesoft.com/mq/stats/api/v1/organizations/ORGANIZATION_ID/environments/ENVIRONMENT_ID/regions/REGION_URL
/queues/95bgpyxYsVyFE?startDate=Thursday, 8 Nov 2018 04:49:37 GMT
&endDate=Sun, 11 Nov 2018 04:60:44 GMT
&period=600

{
    "destination": "95bgpyxYsVyFE",
    "messages": [
        {
            "date": "2018-11-08T04:59:37.000+0000",
            "value": 0
        },
        {
            "date": "2018-11-08T05:09:37.000+0000",
            "value": 0
        }
    ]
}

The duration is an integer and is the granularity of data points in seconds.

Historical Statistics for Exchanges

Retention policies are the same as in the previous Historical Statistics for a Queue section.

/exchanges/{exchangeId}?startDate=…​&endDate=…​&period=…​

Sample Request and Response:

https://anypoint.mulesoft.com/mq/stats/api/v1/organizations/ORGANIZATION_ID/environments/ENVIRONMENT_ID/regions/REGION_URL
/exchanges/exchange-test?
startDate=Wed%2C%2014%20Nov%202018%2021%3A53%3A08%20GMT
&endDate=Wed%2C%2014%20Nov%202018%2022%3A53%3A08%20GMT
&period=360

{
    "destination": "exchange-test",
    "messagesPublished": [
        {
            "date": "2018-11-14T21:59:08.000+0000",
            "value": 0
        }
     ]
}

Note that period is an integer here. It’s the granularity of data points in seconds.

Usage Metrics by Environment

The Stats API can be used to sum up the usage for Anypoint MQ across all environments for a particular organization. This is not real-time and has a latency.

/environments/ENVIRONMENT_ID?startDate=…​&endDate=…​&period=…​

Sample Request and Response:

https://anypoint.mulesoft.com/mq/stats/api/v1/organizations/ORGANIZATION_ID/environments/ENVIRONMENT_ID
?startDate=Thursday, 8 Nov 2018 04:49:37 GMT
&endDate=Sun, 11 Nov 2018 04:60:44 GMT
&period=1day

[
    {
        "timestamp": "2018-11-08T00:00Z",
        "apiRequestCount": 0,
        "messageReceiptCount": 0,
        "billableUnitCount": 0,
        "messageByteCount": 0
    }
]

Usage Metrics by Organization

The Stats API can be used to sum up the usage for Anypoint MQ across the master business organization:

/organizations/ORGANIZATION_ID?startDate=…​&endDate=…​&period=…​

Sample Request and Response:

https://anypoint.mulesoft.com/mq/stats/api/v1/organizations/ORGANIZATION_ID?
startDate=Thursday, 8 Nov 2018 04:49:37 GMT
&endDate=Sun, 11 Nov 2018 04:60:44 GMT
&period=1day

[
    {
        "timestamp": "2018-11-08T00:00Z",
        "apiRequestCount": 0,
        "messageReceiptCount": 0,
        "billableUnitCount": 0,
        "messageByteCount": 0
    }
]

Example: Anypoint MQ Stats API

To access the Anypoint MQ Stats API, you must first authenticate using the Anypoint Access Management API.

These statistics are provided:

  • messagesVisible

    The number of messages that can be retrieved from a queue.

  • messagesSent

    The number of messages added to a queue.

  • messagesReceived

    The number of messages received in a queue.

  • messagesAcked

    The number of acknowledged messages, including any messages deleted using the Anypoint Platform > MQ user interface.

Example request to list statistics for July 26 to July 28, 2018:

curl -X GET \
'https://anypoint.mulesoft.com/mq/stats/api/v1/organizations/ORGANIZATION_ID/environments/ENVIRONMENT_ID/regions/REGION_URL/queues/randomQueue/?startDate=Thu%2C%2026%20Jul%202018%2000%3A00%3A00%20GMT&endDate=Sat%2C%2028%20Jul%202018%2020%3A00%3A00%20GMT&period=600' \
  -H 'authorization: Bearer BEARER_TOKEN' \
  -H 'cache-control: no-cache' \
  -H 'postman-token: ACCESS_TOKEN'

Example: Create Queues and Exchanges with Groovy

To create queues and exchanges programatically, you can use a language such as groovy.

The following example consists of the cloudhub.properties file in whi you list the queues and exchanges to create, and a script file that references the properties file.

Dates

Anypoint MQ lets you specify start and end dates for the Stats API in standard ISO 8601 format.

For example: 2018-10-23T13:00:00Z

Invoke a Command

After modifying the properties file for access to your Anypoint Platform account, use this command to start the script file:

groovy <program_name>.groovy

Configure a Properties File

The following example properties file defines the access credentials, organization ID, environment ID, region ID, and the names of the queues and exchanges to create:

username="<anypoint_platform_username>"
password="<anypoint_platform_password>"
organizationID="ORGANIZATION_ID"
environmentID {
    development="DEVELOPMENT_ENVIRONMENT_ID"
    qa="QA_ENVIRONMENT_ID"
    staging="STAGING_ENVIRONMENT_ID"
    production="PRODUCTION_ENVIRONMENT_ID"
}
regionID="REGION_URL"

queues=[
    "Queue1",
    "Queue2",
    "QueueN",
]

exchanges=[
    "Exchange1",
    "Exchange2",
    "ExchangeN"
]

See the Anypoint MQ FAQfor the regions where Anypoint MQ and FIFO queues are available.

Create a Script File

This example script creates the queues and exchanges listed in the properties file:

Example: Broker API Publish a Message

This example uses the MQ Broker API to publish and consume messages and test Anypoint MQ from the command line using curl.

You must substitute the placeholder string, 42544254-4254-4254-4254-425442544254 for the proper values for authorization and token strings. These examples use Postman to access the queue.

The following curl command publishes a message:

curl -X PUT -H "Content-Type: application/json" \
-H "Authorization: bearer 42544254-4254-4254-4254-425442544254" \
-H "Cache-Control: no-cache" \
-H "Postman-Token: 42544254-4254-4254-42544254-425442544254" \
-d '{ \
  "properties": {
    "userDefinedHeader": "User defined stuff",
    "anotherUserDefinedHeader": "Random stuff"
  },

  "body": "This is a message payload"
}
' "https://mq-us-east-1.anypoint.mulesoft.com/api/v1/organizations/42544254-4254-4254-4254-425442544254/environments/42544254-4254-4254-4254-425442544254/destinations/postmanExchange/messages/552"

The following curl command gets a message:

curl -X GET -H "Authorization: bearer 42544254-4254-4254-4254-425442544254" \
-H "Cache-Control: no-cache" \

See the MQ FAQ for the regions that Anypoint MQ and FIFO are available in.

Example: Postman, Studio, and Browser

This example enables you to test Anypoint MQ from Postman, Anypoint Studio, and a browser:

Set Up Postman

The Postman app provides a platform for accessing the Anypoint MQ APIs. After downloading and installing Postman, supply this information to create an environment:

  • ORGANIZATION_ID

  • ENVIRONMENT_ID

  • Bearer (Authentication) Token

  • Host ID (from Anypoint Platform/Anypoint MQ)

  • Client ID (from Anypoint Platform/Anypoint MQ)

  • Client Secret (from Anypoint Platform/Anypoint MQ)

  • Queue name (you can set this queue name in Postman)

After you authorize access to an Anypoint MQ API, you can then publish a message, consume the message, and get the lock ID from the returned information in the body.

For example, this information is returned from the consume (GET) command:

{
    "properties": {
      "anotherUserDefinedHeader": "Random stuff",
      "userDefinedHeader": "User defined stuff"
    },
    "headers": {
      "messageId": "514",
      "lockId": "<lockIDvalue>",
      "created": "Tue, 23 Oct 2018 21:17:57 GMT",
      "deliveryCount": "2"
    },
    ...

After you have the lock ID, you can add it to your Postman environment to facilitate future requests.

Set Up Studio for API Access

Anypoint Studio enables you to create a Mule app that uses the Anypoint MQ connector. This section summarizes the steps.

You can set up a Studio project with:

  • An HTTP connector:

    • Host 0.0.0.0

    • Port 8081

    • Path in the properties menu set to /mq/{messageId}.

  • Anypoint MQ connector with the client ID and client secret from Anypoint Platform > MQ, and the Destination set to the queue you created in Postman.

  • Logger with Message set to the #[payload] value.

    1. Right-click the project name in the Package Explorer window and click Run As > Mule Application.

      Ensure that the Console messages end with the DEPLOYED value. .In Postman, publish a new message.

Browser Access

After you set up an HTTP Listener in Studio, browse to the address 0.0.0.0:8081. The browser displays the message sent by Postman, which the Anypoint MQ connector received, and the HTTP connector sent to the browser.
