Bulk Onboarding API - Introduction

The Bulk Onboarding API enables partners and large accounts to onboard multiple merchants programmatically - at scale, with minimal manual effort.

Instead of onboarding merchants one by one through the Customer Hub or through our Onboarding Manager team, you can automate the entire process using a single API flow. This is especially useful for acquirers, PSPs, and platforms managing hundreds or thousands of merchants.

What you can do with Bulk Onboarding API?

• Onboard multiple merchants or MIDs in a single request
• Automatically create merchant records with required identifiers and metadata
• Reduce onboarding time from days to minutes
• Eliminate manual setup and human error
• Seamlessly integrate onboarding into your existing systems

How it works?

As a large account or partner, you have full control over merchant lifecycle management in Justt - create (onboard) merchants on demand, retrieve merchant lists or individual merchants by ID, and deactivate merchants whenever required.

If your merchants use multiple integrations (PSP or gateway connections), you have full control over their integrations as well. You can add new integrations, retrieve the full integrations list or a specific integration by ID, and deactivate integrations whenever needed.

Designed for scale

The API is built to handle high-volume onboarding while maintaining data integrity, transparency, and clear error reporting - so you always know exactly what was onboarded and what needs attention.
