Integration App
Build your own Unified API and much more.
Merge.dev
First-generation static Unified API
Real-time Data
Integration App maps requests and responses in real-time. You always work with fresh data and real-time events.
Data Snapshots
Merge makes a copy of your customer data in their database once a few hours and lets you query it. Your integration data is always outdated.
Any Integrations
You can integrate with any app using Integration App. Apps can be fully unstructured like Airtable, Notion, file storages or databases.
Unifiable integrations only
With Merge you can only integrate with apps that have standard data models. This means no Google Sheets, Airtable, Notion, or databases.
Editable and custom connectors
Over 1500 pre-built connectors provided by Integration App is just the starting point. You can edit any part of any connector and build your own with our powerful Connector Builder tool.
Static Connectors
Merge.dev offers a pre-built set of connectors. You cannot edit them. You cannot add your own. If Merge-provided connectors don't cover 100% of your use cases, you are stuck.
Editable and Custom Data Models
We offer unified data models as a starting point, but then you can change how they work for each individual application or even individual customer with field mappings, data sources, and metadata.
Static Data Models
When you need a data model Merge does not provide or even if you need to change something in the data model they provide, you can't do it.
Pre-built or fully custom UI
We offer a library of pre-built UI components and headless API that lets you build fully custom UI without using any of our HTML or styles.
Pre-built Ul only
You have to use Merge Link UI even if it doesn't work for your application. There is no way around it.
