Client request

Transaqo API

Provider route

Illustrative request pattern. Final fields and supported operations depend on the implemented API version and connector.

Start in Test Mode

Explore the platform before requesting production access.

Create a Transaqo account and begin integration work in a non-production environment. Review credentials, configure supported test connectors, send test requests, inspect responses, and validate operational flows before preparing for launch.

Test and production remain separate. Production access is requested after the intended providers, deployment model, security configuration, and operational contacts have been defined.

Create a Test Mode account

Access the dashboard and begin reviewing the available developer environment.

Obtain test credentials

Use non-production credentials for the applicable integration and test environment.

Configure a supported connector

Add the credentials and settings required by the selected provider sandbox.

Send and inspect test requests

Review request handling, responses, payment outcomes, errors, and webhook events.

Prepare for production

Confirm the implementation scope and request the appropriate production environment.

One API for Multiple Providers

Keep provider-specific logic behind one technical layer.

Use a consistent Transaqo integration while connecting to different PSPs, acquirers, payment methods, authentication services, and other supported payment providers. The platform maps supported requests into the format required by each connection and returns payment outcomes through a centralized environment.

01Client application

Submits the supported payment request and receives operational events.

02Transaqo API

Provides the standardized integration entry point and response model.

03Connector layer

Maps supported requests, statuses, errors, and webhook events.

04Selected provider

Processes the eligible operation under the client’s provider account.

Developer Resources

The references needed to build, test, and operate an integration.

Developer materials can cover the initial setup, supported operations, event handling, connector requirements, and the path from Test Mode to production.

Final documentation URLs and downloadable resources will be linked when the applicable public documentation environment is published.

Quickstart

Create an account, obtain test credentials, configure a supported connector, and submit an initial test payment.

Guide

API Reference

Review available endpoints, parameters, response structures, authentication requirements, and supported payment operations.

Reference

SDKs & Checkout Components

Understand the available implementation options for supported web and mobile payment experiences.

Components

Webhooks

Receive payment and operational events and update order, customer, or internal workflow status.

Events

Test Data

Use available test cards, provider sandboxes, and simulated scenarios to validate the implementation.

Testing

Error Handling

Distinguish declines, technical failures, authentication requirements, and configuration issues.

Reference

Connector Configuration

Review the credentials and settings required to activate supported payment providers.

Setup

Postman Collection

Explore selected API requests without first building the complete application integration.

Testing

Request, Response & Event

Follow one payment through the integration flow.

A standardized request can produce a normalized response and an operational webhook event. The exact schema and supported fields depend on the published API version and selected connector.

The JSON below is illustrative and is not a substitute for the final API reference.

{
  "amount": 4200,
  "currency": "EUR",
  "payment_method": "card",
  "reference": "order_test_1042",
  "mode": "test"
}

{
  "id": "payment_test_1042",
  "status": "processing",
  "reference": "order_test_1042",
  "mode": "test"
}

{
  "type": "payment.status_changed",
  "data": {
    "id": "payment_test_1042",
    "status": "completed"
  }
}

Build the Payment Experience You Need

Choose the integration approach around your product and infrastructure.

Use hosted or embedded payment components where appropriate, or build a custom experience using available APIs and the selected payment-data architecture. The implementation method affects complexity, customer experience, and payment-security scope.

Hosted components

Use a provider-managed or platform-managed payment surface where it fits the selected implementation.

Embedded flows

Integrate supported payment components into the client’s web or mobile customer experience.

Custom API experience

Build the customer-facing workflow around the available APIs and supported payment-data configuration.

Separate Environments

Test safely, then define the production implementation.

Test Mode and production processing are separated to reduce the risk of using live credentials or processing real payments during development. Production readiness is reviewed against the intended providers, deployment model, security configuration, payment flows, and operational contacts.

Non-production

Technical Support

Support for implementation decisions and production readiness.

Transaqo can assist with the technical questions that connect provider configuration, payment-flow design, integration work, and production preparation.

Support scope and response arrangements depend on the selected commercial plan and implementation.
