Click here to access Sendlane’s API Documentation, which contains a full index of Sendlane’s API calls and how to implement them!
Before Getting Started
In order to use the Sendlane API, you'll need to have your your Sendlane API Key, Hash Key and Subdomain ready. These can be found in your Sendlane account under Account → API.
If you are located outside of the US and have a proxy set up, you may experience issues making successful API calls.
Turning off your proxy is the best option for troubleshooting an error where the system “Could not get any response.”
