Start with your needs.

For businesses whose applications need to exchange data. We map the source, destination and exchange rules before building the integration.

Reduce duplicate entry

Data moves through an agreed workflow so the team need not keep copying the same information.

Clearer transaction status

Webhooks and status checks help the application follow changes from the provider.

Easier for your team to maintain

Documentation explains the endpoints, configuration and failure handling implemented.

Clear scope from the start.

The following points guide the discussion. Included work and handover deliverables are defined in your proposal.

  • Map data, endpoints and integration flows.
  • Server-side authentication and credential storage.
  • API or webhook integration based on vendor documentation.
  • Data validation, failure handling and retries appropriate to the workflow.
  • Test core flows and agreed failure scenarios.
  • Configuration documentation, deployment and handover.

Choose the right next step.

Start with focused needs and expand the scope when necessary.

Know the next steps.

Each stage has a purpose and deliverables you can review.

  1. Map systems and access

    Share API documentation, business workflows and access limits.

  2. Build and test in a test environment

    The integration is checked with test data before handling live transactions.

  3. Launch and hand over guidance

    Activation follows approval of the workflow, with documentation and result checks.

Prepare for the discussion.

Initial information helps us assess your needs and prepare a suitable proposal.

  • Applications, vendors and API documentation.
  • Example workflows and test data without sensitive information.
  • Sandbox accounts and technical access limited to what is required.

Frequently asked questions.

Confirm the scope and terms before starting work.

Are API provider fees included?

Vendor fees, payment processing fees, API subscriptions, servers and licenses are separate from development costs unless included in the proposal.

What if the existing system has no API?

We review official options such as data imports/exports or supported connectors. Feasibility and limitations are explained before work starts.

Can you integrate Midtrans or Xendit?

This can be discussed based on your API product, documentation and merchant access. Account activation and provider approval remain subject to vendor terms.
