Payment and Financial API
Integration

Connect your fintech product to the services it depends on.
Zimozi develops payment and financial API integrations for fintech applications. We connect selected providers with your product and build the status tracking, validation and exception handling around each connection.

A PRACTICAL FIRST STEP

Make connected information usable.

01

The starting point

An integration needs more than a successful API call. Your application must understand what a response means, update the right records and handle situations where a provider does not reply.

02

How we scope it

We define those behaviours before connecting the systems.

03

Payment gateways

Payment gateway and payment service provider connections.

04

Handle uncertain transaction states

A timeout may leave the outcome unknown. The integration needs a way to check status before repeating an action. We plan safe retries, provider status checks and operational review for unresolved cases.

05

Testing and ongoing changes

Testing includes authentication, expected responses, invalid inputs and provider failures. Documentation covers the data mappings and recovery process. Support can include provider API changes and credential rotation under an agreed plan.

From idea to everyday use.

  1. Discover

    Understand the users, current process and intended result.

  2. Assess

    Review the data, systems, access and review needs.

  3. Develop

    Build a focused pilot around the agreed use case.

  4. Deploy

    Connect the solution to the workflow and test exceptions.

  5. Evolve

    Monitor quality, usage and costs, then improve.

IN PRACTICE

A practical use case.

Testing and ongoing changes

01

The situation

A payment provider sends a transaction update more than once.

02

The workflow

The application needs to recognise the repeated event and avoid creating duplicate records. We can build event tracking and validation so updates are applied consistently and exceptions remain visible.

03

In context

This example illustrates a potential workflow, not a claimed customer result.

04

Project scope

Testing includes authentication, expected responses, invalid inputs and provider failures.

05

Delivery details

Documentation covers the data mappings and recovery process. Support can include provider API changes and credential rotation under an agreed plan.

Send message

We assess the selected provider, account eligibility, API access and supported payment flows before confirming the work.

Access varies by provider and market. The product scope must reflect the APIs and permissions actually available.

Yes. API version updates, error investigation and integration monitoring can be included in ongoing support.
