Fintech Integration Phases

Getting Started > Fintech Integration Phases

Introduction

A commonly asked question by new Fintechs to the Fintech Integration Network (FIN) is “How quickly can we implement our product into a financial institution’s environment?”. We have broken this process into phases for better understanding and project planning.

Pre Development Phases

Phase 1 - Joining the FIN

Before a Fintech is able to begin using our Enterprise Integration software, they will need to join the FIN. This process may be started by submitting a FIN Interest Form.

Turnaround Time
7-14 business days

Phase 2 - Paperwork

To become part of the FIN there will be contracts, paperwork and fees to be completed. The amount of time during this phase varies depending on a the turnaround of the FIN paperwork and payment to Jack Henry (JH) by the Fintech.

As part of the paperwork and FIN payments process, a Fintech will provide JH the name(s) of the REST providers they wish to integrate into their solution.

Turnaround Time
1-2 months average

Development Phases

Phase 3 - Development

Once the previous phase is completed, access will be granted to the Fintech into our development sandbox. This sandbox is used by all Fintechs in the FIN to complete their initial development efforts.

The amount of time during this phase varies substantially, depending on Fintech’s product complexity, and Fintech resources allocated.

Turnaround Time
3-12 months

Phase 4 - Integration Readiness Check

After the development efforts are complete, a Fintech’s product must pass a Integration Readiness Check (IRC) before being allowed to implement at a Financial Institution. Complete details on this requirement can be found on our Fintech jXchange REST Requirements and Readiness page.

If you have completed development and are ready to take the IRC, please fill out the Integration Readiness Check Request Form and someone from the Developer Relations team will provide next steps.

Turnaround Time
5-10 business days

Phase 5 - Final solution documentation

At the conclusion of the IRC, the Developer Relations team will request information regarding the product and Fintech contacts to receive credentials. This ensures that we have everything documented internally for our operational teams to understand the product’s integration requirements.

Turnaround Time
1-2 business days

Implementation Phases

The following phases are designed to ensure clear communication between the Fintech and the Financial Institution (FI) during the implementation of the Fintech solution within the FI’s environment(s).

Note: These steps must be repeated for each new FI that the Fintech integrates with.

Phase 6 - Preparing Your FI for Integration

Once all development phases are complete, the Fintech should notify their Financial Institution (FI) contact that they are ready to begin FI implementation. This step requires the FI to complete the subsequent phases and will also require the Fintech to provide the FI with the following information:

  • Fintech Name
  • Fintech Valid Consumer Name
  • Fintech Valid Consumer Product
  • JX-REST Products

Responsible Party: Fintech

Turnaround Time: Varies dependent on the Fintech

Phase 7 - Implementation at Financial Institutions

Once the previous steps are completed, the Fintech will need to inform their contact at the financial institution that a For Clients Portal case will need to be created with the following:

  • Problem Summary: Request to implement {Fintech’s Name and Fintech’s Product} solution

  • Description: Please route this case to the jXchange Implementations team to implement the following

    • Fintech Name
    • Fintech Valid Consumer Name
    • Fintech Valid Product Name
    • Financial Institution Environment(s) to be used for the implementation
    • Any FI specific special instructions
  • Product: JX_JXCHANGE

  • Problem Type: Implementations

This phase is repeated for each new financial institution that wishes to implement the Fintech’s product.

Turnaround Time
The usual Implementations Team backlog for this item is 30-45 calendar days.
