Get Started

Before using the Postman Collection, you will need to begin your integration and compliance review with TabaPay. This includes receiving your Sandbox Credentials and whitelisting your IPs. To begin your implementation, email help@tabapay.com.

Step 1: Download the Collection

Download the TabaPay Postman Collection

Download Postman (if you don’t already have it installed)

Step 2: Configure Your Sandbox Environment

To begin testing, you’ll need to populate the following environment variables in your TabaPay Sandbox Environment. These values are provided by TabaPay when Sandbox credentials are issued.

You can customize the descriptions below or link to a credential reference page.

Required Environment Variables

Variable Name(s):

FQDN: The Sandbox base URL you are testing against
bearertoken: Authorization credential used to make authenticated API requests
ClientID: Your unique 22-character client identifier issued during onboarding

Note: These values are sensitive credentials. Never expose them publicly or share them with anyone who is not authorized.

Step 3: Make Your First API Call

Once the environment variables are populated:

Navigate to Retrieve Client
Select Send

A successful response confirms:

Your credentials are valid
Your client configurations and limits

Your environment is configured correctly, and you’re ready to begin testing additional workflows

Tokenization

Tokenization is the process of replacing sensitive payment data (e.g. a card number or bank account number) with a unique, non-sensitive placeholder called a token. TabaPay enables its users to generate tokens in many different use cases, but one of the main uses is payment tokenization with Account IDs—rendered as the variable accountID. An accountID is TabaPay's own unique set of 22-character string generated by Create Account that represents a single payment card number or bank account.

Managing accountIDs in Sandbox

Due to PCI standards, tokenized payment credentials are widely used among fintech platforms. Tabapay's accountIDs are commonly used among clients for all use cases for both payment acceptance and payouts.

Using the TabaPay Postman Collection, you can generate these accounts in Sandbox.

To Generate an AccountID:

Go to the TabaPay API Postman Collection
Go to Account > Create Account
Choose the request based on your payment instrument:
1. Card
2. Bank
3. RTP-enabled bank
Select Send

When the request succeeds:

A new accountID is generated
The Sandbox Environment variable is automatically updated under Current Value
Once configured, you can freely test different payment flows using your generated accountID.

Optional: Disable Auto-Updates

If you are testing different use cases, and generating multiple accountIDs you may want to avoid automatically updating the accountID environment variable. If you prefer a more manual control to avoid the accountID variable automatically updating, complete the following:

Go to Collections > *TabaPay API *
Select Account > POST Create Account
Go to Scripts
Paste in the following, comment out, or delete the script in Post-res (Post response).

JavaScript
//var jsonData = pm.response.json();
//if (jsonData.accountID){
// pm.environment.set("accountID", jsonData.accountID); 
//}

Your accountIDs variable should now remain unchanged after creating new accountIDs.

Note: The script will be active by default you will need to comment out to disable.

Working with transactionIDs

The same process or updating will happen for the following unique IDs

transactionIDs: Generated when transactions are created. The transactionID variable is automatically updated in your Sandbox Environment by default.

If you do not want this behavior:

Navigate to the relevant Post Create Transaction - Pull Card, or, Post Create Transaction - Push Bank

Go to the Scripts section > Post-res and follow the same steps as in Optional: Disable Auto-Updates.

Other Auto-Updates include

KeyID: To remove go to Collections > Key > POST Create Key > Scripts > Post-res.

Types of Transaction Flows

Other transaction flows include:

Create Transaction – Pull Card
Create Transaction – Pull Bank
Create Transaction – Push to Card
Create Transaction – Push Bank
