Test the API

Highnote’s test environment replicates the full functionality of the live environment, providing simulations for tasks related to real-time transactions or compliance scenarios. Highnote's documentation has an API Explorer that lets you interact with the Highnote API to simulate capabilities and transactions in your test environment. This guide provides an overview of how the API Explorer works and instructions for using it.

The API Explorer can be used in two ways:

• Embedded code snippets: Highnote uses embedded instances of our API Explorer directly in Highnote's documentation. These instances appear as testable code snippets. You can use the sample query supplied in each instance of the built-in tool to send requests to the Highnote API executed in your test environment.
• Highnote API Explorer: The Highnote API Explorer provides an interface to execute API calls in your test environment, perform queries, and search the Highnote API schema. You can use the default collection or create a custom collection of API mutations and queries that can be shared with your team:

To use Highnote's embedded code snippets, you must sign in to your Highnote account. Once signed in, the embedded code snippets will communicate with your test environment.

In the following steps, we use steps from the embedded code snippets provided for Create your Card Product as an example:

1. Review the query section of the embedded API Explorer. You do not need to change anything in this section for testing purposes.
2. Click Variables to open the variables section. You can either use the pre-filled inputs or customize them for testing purposes.
3. Click Run Query to execute the request in your Test Environment.
4. The Results section will populate the request response.
5. Open your Highnote dashboard and verify that the request is executed correctly in your test environment. If you use the default values, "My Test Product" will be listed as a Commercial Debit product in your dashboard.

To use the Highnote API Explorer, you must sign in to your Highnote dashboard.

The API Explorer’s default collection is organized into several folders representing different parts of the Highnote platform. Pre-configured queries and mutations that represent operations are nested inside each folder.

Use the following steps to use the API Explorer's default collection:

1. Open the API Explorer, click on any folder, and select an operation.
2. The pre-configured query, mutation, and variables associated with the operation automatically populate in the API Explorer interface. You can edit the pre-configured fields by clicking on the corresponding line and replacing the existing text, or you can leave the fields as they are.
3. Click Run Query or Run Mutation to execute the API call.
4. The response will populate in the Results field. You can also launch your test environment and verify the API call is executed correctly in the dashboard.

In the API Explorer, you can create custom collections by clicking the Collection drop-down and selecting Create New Collection. In a custom collection, you can create new operations and folders, build customized queries and mutations, and execute them in your test environment.

Use the search schema functionality, query, and mutation resources when creating custom operations.

The API Explorer has an autocomplete feature that populates options based on what’s in the schema. You can use the autocomplete feature to help you build your queries and mutations in your custom collection.

Use the following steps to use the autocomplete feature to build a simple query:

1. Open your Custom Collection and click Create New Operation to populate an empty query.
2. Start typing qu and choose query from the autocomplete box.
3. Add curly brackets { }.
4. Inside the curly brackets, start typing ca and select cardProducts from the autocomplete box.
5. Click Run Query. The corresponding objects for the query will populate in the Query field.
6. The Results field will return a paginated list of card products from your test environment.
