If you'd like to use a Merge SDK to integrate with Merge instead of forming your own API requests, you can find the installation and usage instructions for all of our available SDK's here.
We highly recommend using our Complete Category SDKs as they are more frequently updated and provide flexibility in case you find new Merge API categories useful in the future.
API requests to Merge's Unified API are rate limited to the following per linked account (as identified by the
account_token attached to the request):
- Launch: 100 / minute
- Grow: 400 / minute
- Expand: 600 / minute
