Testing the APIs

The ASIG sandbox is an isolated test environment where you can try out the standardized APIs. Below are instructions on how to make your first API call within this sandbox, or an API REST tool like Postman (see below). A sample set of data is available for each API to allow you to simulate an API call in a production environment.

 

API Calls

A series of fields are enabled to customize the call for each API. All API calls are structured with the following components:

Resource URL

Header Parameters

Try it out!

Some APIs will also include a Query Parameter.

 

 

Return Codes

 

The API will always return an HTTP STATUS. The table below summarizes the general response codes that are returned in the APIs.

 

 Code

 Description

2XX

The API call was successful.

4XX

The API call had an error. The error will be encoded in the body of the response.

5XX

The API call was unsuccessful. You should retry later.

API Testing

 

Select the API that you want to test:

Bank Contact

Bank Contact API Test Data

Use the sample bank contact test data below to test varying outcomes. The data with the positive response has been preloaded into the sandbox.

Follow the instructions provided for the specific API test components and use the highlighted areas to populate the relevant fields.

 

Resource URL

Resource URL needs to be customized for the Bank Contact API. If you hover your mouse over bankid, you will find an explanation of the field. Edit and insert a 9-digit value in the Resource URL.

Bank ID Resource

 

 

 

Set the Query Parameter with the reason for inquiry.

Query Parameter

 

 

Header Parameter

Select “application/json” in the drop down menu for Content-Type for the Header Parameter.

Header Parameter

 

Try it out!

Set API Key information as previously provided in the Getting Started page. 

Try it Out

Insert the following information in the open dialogue box:

  1. Name = "apikey" (all lowercase)
  2. Set value copied from the “Consumer Key” (make sure there is no space before or after the string of characters)
  3. Select “Query”

 

Custom Token

 

After customizing the call components, click the “SEND” button to execute the API call. The “RESET” button will reset all the fields to the ones used by default.

 

 

Response

A positive API call will return a JSON that contains the information about the bank contact:

OK Response

 

If you test a call that does not include one or more of the required values, or if you test a call that provides an invalid value, you’ll receive the appropriate error response. When there is a 4XX error, additional description will help debug errors.  

 

Example of an error response with an incorrect bank ID (i.e., bank transit routing number):

404 Not Found Response

An error response for an invalid inquiry request e.g., WIRE_FRAUD: 

404 Bad Request

 

Account Validation API Test Data

Account Validation test data is provided below with a variety of realistic account information.  This data has been preloaded into the sandbox and should all return a successful account validation outcome of 200 OK – Enabled or 200 OK – Disabled if used correctly in the API.

*NOTE: A response may return as 200 OK – Disabled if the API call request information is correct, but the account is closed, or may not accept a credit or debit payment.

 

Using the sample customer-related data below will provide you with examples of failed API calls.  These should all return a negative response of 404 Not Found – Disabled.

Postman

In this section, we take a look at how to make direct HTTP requests by using Postman.   If you are new to Postman, see the Postman documentation and tutorials.

For a GET request like Bank Contact API insert the Resource URL and set the Consumer Key “?apikey=” with the appropriate credentials, followed by the reason i.e., “&reason=ACH_FRAUD” as shown below:

Postman GET

 

For a POST request like Account Validation, information has to be passed in the header and the body of the HTTP request (changing the values as required) as shown below.

 

 Postman POST

 

The header includes the Resource URL and Consumer Key with raw json content sent in the request body.

Postman Body Raw

*NOTE: In order to send json in the request body, select the radio button raw and set the text to “JSON(application/json).”
