Skip to main contentThe Invopop API is split into multiple services. Each service is effectively a namespace
for the different problem domain that we’re trying to provide solutions for.
The current list of key services is:
- Silo 
/silo/v1 · Data store for GOBL documents and their attachments. The silo is also responsible for validating incoming data with the GOBL libraries, managing versions, and state control. 
- Transform 
/transform/v1 · Responsible for storing workflow definitions and executing “jobs”. 
- Sequences 
/sequences/v1 · Provides reliable and scalable support for generating sequential codes typically added to invoices. 
- Access 
/access/v1 · Provides access to workspaces and additional functionality required by Applications for enrollment handling. 
- Utils 
/utils/v1 · Is used for testing the connection and access credentials. 
The details for each service are described in the following sections.
