Start Integrating with LOOP API
Our API allows you to merge, convert and combine files on the web. We can convert and fill (merge) a number of file types.
Supported file types (bold file types can be filled (merged) with data)
Supported Interfaces
Our API supports both SOAP and REST interfaces. SOAP is an XML based interface designed specifically for web services and object serialization. REST is an interface based around the HTTP protocol used by normal web calls with a primary goal of simplicity.
REST Authorization
Every SOAP call explicitly takes a userId, password and key. While not explicit, these parameters also need to be passed with every call to any of our REST methods. These parameters can be sent through the querystring, post parameters or the authorization header. For security reasons, we recommend using either the authorization header or post parameters. If these parameters are sent over multiple channels, the authorization header takes precedence, followed by the post parameters, followed by the querystring variables.
Querystring or Post Parameters
userId=userId&password=password&key=key
Authorization Header
Authorization: userId=userId,password=password,key=key
