Linked Accounts represent your users’ integrations after they authenticate a third-party platform through Merge Link. You can create both Production Linked Accounts and Test Linked Accounts. We understand testing an integration in your sandbox environment is important for you before offering an integration to your customers!
If you want to test an API key rather than a production one, we suggest you create a test account to link. In the Merge Dashboard, under Linked Accounts, you will see both Production and Test Linked Accounts. On the Launch plan, you are eligible to link up to 3 test accounts, and on Grow and Expand plans you receive unlimited test accounts.
It is important to note Test Linked Accounts do not count towards billing and can only be synced manually through this dashboard.
