Corporate Onboarding

Unlock multi-currency accounts for your clients, compliantly and at scale.

Integrate Sokin’s compliance-first Onboarding API to provision multi-currency accounts for your clients directly within your platform.

As a Sokin Partner, you remain the primary interface for your clients. Sokin provides the regulated financial infrastructure and performs the required review.

Once approved, onboarded clients gain access to:

26+ currency accounts

Payouts to 170+ countries

A secure, globally compliant payments infrastructure

You manage the user experience. Sokin manages compliance and account issuance.

Overview

An onboarded client is an organisation or individual (Soletrader) on your platform who is issued a Sokin account under Embedded Payments.

Before an account can be created and activated, the client must first be onboarded to Sokin. This ensures compliance with applicable regulatory and due diligence requirements.

Onboarding is initiated by submitting the required data via the API.

Flexible due diligence models

Sokin supports multiple onboarding models to align with your regulatory structure and operational setup.

The applicable model is determined by your partnership setup and your client’s jurisdiction.

Available models

Non-Reliance

Best for partners who prefer Sokin to conduct full verification.

Global coverage

Full corporate and associate documentation required

Sokin performs complete compliance review

Semi-Reliance

Best for partners operating under structured reliance frameworks.

Global coverage

Full corporate and associate documentation required

Mandatory Due Diligence Bundle (Partner-provided KYC/KYB evidence)

Shared compliance responsibilities

Limited availability model

Data Only (Non-Doc)

Onboarding API structure

The onboarding process is divided into three API groups, each representing a stage in the onboarding life cycle.

It is strongly recommended to implement them in sequence, as earlier calls return identifiers required in subsequent requests.

API groups

1. Create a new Corporate

Initialises the corporate onboarding request and creates a draft corporate entity in Sokin’s system.

This endpoint:

Captures core business and compliance data

Determines onboarding model validation

Creates the corporate record

Generates required IDs for associate and document submission

Initiates the account creation workflow (pending approval)

POST
/corporates

2. Add Associates API group

Submits individuals or corporate associates linked to the entity.

Examples include:

Directors

Beneficial Owners (UBOs)

Partners

Corporate Partners

POST
/corporates/associates
/corporates/parent-entities

Associate requirements depend on entity type (see below under Legal entity associates requirement section).

3. Document Attachment API group

Uploads supporting documentation, where required by model.

Corporate documents:
POST /corporates/documents
(For Semi-Reliance, this must also include submission of the Due Diligence Bundle)

Associate documents:
POST /corporates/associates/documents

Parent entity documents (if applicable):
POST /corporates/parent-entities/documents

Mandatory API sequence

To successfully onboard a corporation and provision its account, the following API calls are required:

1.Create a new Corporate
POST /corporates

2.Add an associate to a corporate onboarding request
POST /corporates/associates

3.Add onboarding documents (if required by model)
POST /corporates/documents

4.Add associate documents
POST /corporates/associates/documents

5.Finalise Submission
POST /corporates/finalise-submission

Conditional API call

If the ownership structure includes a parent company or layered corporate ownership, the following endpoint becomes mandatory:

Add a parent entity (corporate associate) to an onboarding request
(POST /corporates/parent-entities)

Parent entity details (company and associate details, along with required documents) must be submitted before finalising the onboarding request. Failure to provide required layered ownership data will result in validation errors or rejection at review stage.

Final submission triggers compliance review.

POST /corporates/finalise-submission

Legal entity associate requirements

Associate structure is validated based on the legal entity type provided in the Create Onboarding Request.
