Trusted to power integrations at




Ensure the freshest data with multiple sync options from third-party APIs to Merge to your backend, including webhooks, periodic polling, and forced resyncs. Plus, you can always POST or PATCH data instantly.

Merge generates webhooks whenever updated data is available so you can keep your database up to date with minimal polling. You can also access webhooks emitted directly from third-party API providers.
Even better, Merge is able to set up these webhooks right out of the box, where supported. No configuration from you or your end user required.
Merge features a smart rate limiting engine to dynamically handle differences in rate limits and pagination across integrations. You'll never be limited by what data you access.
