Current Version API: 1.0

EnvoyRelate provides a fast and flexible API to allow you to input transactions from your web services. In order to use this you must have an EnvoyRelate account (get started here - don't forget to confirm your account in the activation email we send you) and a Group configured.

We use and accept only JSON.

All calls to the API use the following base URL –

Remember, your Unique Group Key gives update only access to your Group and it is up to you to ensure the confidentiality of this Key.
