Step 2: Set up Postman

Now that you've created a user that's able to access the Amazon Pinpoint API, you can set up Postman. In this section, you create one or more environments in Postman. Next, you import a collection that contains a request template for each of the operations in the Amazon Pinpoint API.

Step 2.1: Create Postman workspace

In Postman, a workspace is an organizational container for projects and environments. In this section, you create at least one workspace to use with Amazon Pinpoint.

Create a workspace

In Postman, choose the more actions choose File, then choose New.

  1. On the Create New window, choose Workspace.

  2. Enter a name, summary, and set the visibility to personal. Then choose Create Workspace.

Step 2.2: Create Postman environments

In Postman, an environment is a set of variables that are stored as key-value pairs. You can use environments to change the configuration of the requests that you make through Postman, without having to change the API requests themselves.

In this section, you create at least one environment to use with Amazon Pinpoint. Each environment that you create contains a set of variables that are specific to your account in a single AWS Region. If you use the procedures in this section to create more than one environment, you can change between Regions by choosing a different environment from the Environment menu in Postman.

To create an environment

  1. In Postman, choose the more actions menu, choose File, then choose New.

  2. On the Create New window, choose Environment.

  3. On the MANAGE ENVIRONMENTS window, for Environment Name, enter Amazon Pinpoint - Region Name. Replace Region Name with one of the following values:

    • US East (N. Virginia)

    • US West (Oregon)

    • Asia Pacific (Mumbai)

    • Asia Pacific (Sydney)

    • Europe (Frankfurt)

    • Europe (Ireland)

    Note

    At a minimum, you only need to create one environment for a single AWS Region, and that AWS Region must contain one project. If you haven't created a project in one of the previously listed AWS Regions, see Creating an Amazon Pinpoint project with email support in the Amazon Pinpoint User Guide.

  4. Create six new variables: endpoint, region, serviceName, accountId, accessKey, and secretAccessKey. Use the following table to determine which value to enter in the Initial Value and Current Value columns for each variable.

    Region Variable Initial and Current value
    US East (N. Virginia) endpoint pinpoint.us-east-1.amazonaws.com
    region us-east-1
    serviceName mobiletargeting
    accountId (your AWS account ID)
    accessKey (your IAM access key ID)
    secretAccessKey (your IAM secret access key)
    US West (Oregon) endpoint pinpoint.us-west-2.amazonaws.com
    region us-west-2
    serviceName mobiletargeting
    accountId (your AWS account ID)
    accessKey (your IAM access key ID)
    secretAccessKey (your IAM secret access key)
    Asia Pacific (Mumbai) endpoint pinpoint.ap-south-1.amazonaws.com
    region ap-south-1
    serviceName mobiletargeting
    accountId (your AWS account ID)
    accessKey (your IAM access key ID)
    secretAccessKey (your IAM secret access key)
    Asia Pacific (Sydney) endpoint pinpoint.ap-southeast-2.amazonaws.com
    region ap-southeast-2
    serviceName mobiletargeting
    accountId (your AWS account ID)
    accessKey (your IAM access key ID)
    secretAccessKey (your IAM secret access key)
    Europe (Frankfurt) endpoint pinpoint.eu-central-1.amazonaws.com
    region eu-central-1
    serviceName mobiletargeting
    accountId (your AWS account ID)
    accessKey (your IAM access key ID)
    secretAccessKey (your IAM secret access key)
    Europe (Ireland) endpoint pinpoint.eu-west-1.amazonaws.com
    region eu-west-1
    serviceName mobiletargeting
    accountId (your AWS account ID)
    accessKey (your IAM access key ID)
    secretAccessKey (your IAM secret access key)

    After you create these variables, the MANAGE ENVIRONMENTS window resembles the example shown in the following image.

    The Manage Environments window in Postman. The screenshot shows an environment named "US East (N. Virginia)". The environment contains the following variables: A variable named "endpoint" and an initial value of "pinpoint.us-east-1.amazonaws.com". A variable named "region" and an initial value of "us-east-1". A variable named "serviceName" and an initial value of "mobiletargeting". A variable named "accountId" and an initial value of 123456789012 (a fictitious AWS account ID). A variable named "accessKey" and an initial value of AKIAIOSFODNN7EXAMPLE (a fictitious access key ID). A variable named "secretAccessKey" and an initial value of wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY (a fictitious secret access key).

    When you finish, choose Save.

    Important

    The access keys shown in the preceding image are fictitious. Don't share your IAM access keys with others.

    Postman includes features that permit you to share and export environments. If you use these features, make sure not to share your access key ID and secret access key with anybody who shouldn't have access to these credentials.

    For more information, see IAM best practices in the IAM User Guide.

  5. (Optional) Repeat steps 1–4 for each additional environment that you want to create.

    Tip

    In Postman, you can create as many environments as you need. You can use environments in the following ways:

    • Create a separate environment for every Region where you must test the Amazon Pinpoint API.

    • Create environments that are associated with different AWS accounts.

    • Create environments that use credentials that are associated with other user.

  6. When you finish creating environments, proceed to the next section.

Step 2.3: Create an Amazon Pinpoint collection in Postman

In Postman, a collection is a group of API requests. Requests in a collection are typically united by a common purpose. In this section, you create a new collection that contains a request template for each operation in the Amazon Pinpoint API.

To create the Amazon Pinpoint collection

  1. In Postman, choose the more actions menu, choose File, then choose Import.

  2. On the Import window, choose Import From Link, and then enter the following URL: https://raw.githubusercontent.com/awsdocs/amazon-pinpoint-developer-guide/master/Amazon%20Pinpoint.postman_collection.json.

    Choose Import. Postman imports the Amazon Pinpoint collection, which contains 120 example requests.

Step 2.4: Test your Postman configuration

After you import the Amazon Pinpoint collection, we recommend that you perform a quick test to verify that all of the components are properly configured. You can test your configuration by submitting a GetApps request. This request returns a list of all of the projects that exist in your Amazon Pinpoint account in the current AWS Region. This request doesn't require any additional configuration, so it's a good way to test your configuration.

To test the configuration of the Amazon Pinpoint collection

  1. In the left navigation pane, select Collections, expand the Amazon Pinpoint collection, and then expand the Apps folder.

  2. In the list of requests, choose GetApps.

  3. Use the Environment selector to choose the environment that you created in Step 2.2.

  4. Choose Send. If the request is sent successfully, the response pane shows a status of 200 OK. You see a response that resembles the example in the following image.

    An example response for Name, Id, Arn and Tags.
    Note

    If you don't have any projects created in the AWS Region then Amazon Pinpoint returns { "Item": [] }.

    This response shows a list of all of the Amazon Pinpoint projects that exist in your account in the Region that you chose in step 3.

Troubleshooting

When you submit your request, you might see an error. See the following list for several common errors that you might encounter, and for steps that you can take to resolve them.

Error message Problem Resolution

Could not get any response

There was an error connecting to https://%7B%7Bendpoint%7D%7D/v1/apps.

There is no current value for the {{endpoint}} variable, which is set when you choose an environment.

Use the environment selector to choose an environment.

The security token included in the request is invalid.

Postman wasn't able to find the current value of your access key ID or secret access key.

Choose the gear icon near the environment selector, and then choose the current environment. Verify that the accessKey and secretAccessKey values appear in both the INITIAL VALUE and CURRENT VALUE columns, and that you entered the credentials correctly.

"Message": "User: arn:aws:iam::123456789012:user/PinpointPostmanUser is not authorized to perform: mobiletargeting:GetApps on resource: arn:aws:mobiletargeting:us-west-2:123456789012:*"

The IAM policy associated with your user doesn't include the appropriate permissions.

Verify that your user has the permissions that are described in Step 1.1, and that you provided the correct credentials when you created the environment in Step 2.1.

Next: Send additional requests
