Sandbox Accounts

Instantly access sandbox environments

Merge provides sandbox accounts with third-party API providers so you can build and test your integrations with confidence.

Talk to our team to learn what sandboxes are available.

Meta Endpoint

Programmatically access required schemas

Third-party providers require specific (and often different) fields to write data to their APIs, making your code a mess.

Dynamically fetch required data schemas from Merge’s /meta endpoint to make POST or PATCH requests that just work.
