Developers
Invoices reach Billabex through several channels at once, and the agent takes it from there. Three ways to feed it and drive it: a REST API, an MCP server for AI assistants, and no-code connectors.
Each one reaches the same business objects: customer accounts, contacts, invoices, credit notes, follow-ups and tasks. Which one you pick depends on who is calling, your application, an AI assistant, or a workflow built without code.
For a deterministic application integration, from your ERP, your billing tool, or your own scripts.
So an AI assistant can read the context of an account and act under your supervision, over Streamable HTTP.
To assemble a scenario without writing code, when the tool that needs to talk to Billabex already has its place in your stack.
The cases below are the ones the API serves in production today. Endpoints, parameters and schemas live on the developer portal.
Push accounts, contacts, invoices and credit notes from a tool Billabex does not connect natively, using a source identifier as the reconciliation key.
Read the aging balance, per-account balances and payment promises to feed an internal dashboard or an existing report.
List open tasks, answer them from your own tool, and close them once the missing information has been provided.
Retrieve the follow-ups sent and the replies received, with their delivery status, for archiving or auditing.
Update the paid amount on an invoice or record an announced payment, so the next follow-up takes it into account.
Read the organization audit journal, one entry per successful command, filterable by account and by actor.
An agent or a client generator can discover the full contract without creating an account and without authenticating first.
Three public repositories, usable and readable before you commit to an integration.
