The Unified API for customizability
Merge is a Unified API for customer-facing integrations. Embedded integration platform as a service (iPaaS) is a low-code tool.
With Merge, you only need to build once. Merge also offers the same depth of data extensibility as an embedded iPaaS.
01
Stop maintaining one-off integrations
Merge allows your app to connect to an entire category of software through a single integration. Unlike an embedded iPaaS, you won’t need to use developer resources to build one-to-one integrations for each platform you want to support.

With an Embedded iPaaS
02
Access any piece of data with a single API
Whether you need to read and write custom objects or custom fields and attributes, Merge supports you with features that enable deep data coverage in a single build
Passthrough request
Write code to interact with any third-party API endpoint. Merge is a unified authentication layer.
Remote data
Access integration data via API in the original format
Field mapping
You and your customers can map custom and standard third-party fields into standard fields you create
Remote fields
Get rich metadata for fields not mapped by Merge. When supported, write custom data back.
03
Merge supports the entire integration lifecycle while an embedded iPaaS puts the burden on you
Merge maintains integrations, so you don't have to. Merge also offers observability tools like searchable logs and automated issue detection, enabling your support team to proactively resolve errors.
An embedded iPaaS requires your engineering teams to monitor third-party API changes and to implement logic to catch and debug any issues.

How Bonusly built their HRIS integrations 20x faster using Merge instead of an Embedded iPaaS
“Embedded iPaaS solutions require extensive customizations and force you to build one integration at a time, which isn’t scalable. With Merge, we can build once and access dozens of customizable HRIS integrations that are ready out-of-the-box.”
