AL Bridge
by AppLibra
Let cloud BC print, read folders and reach local devices - the shared foundation under every AppLibra connector.
Live on AppSource
Overview
Business Central SaaS is sandboxed: it cannot print to local printers, read or write folders, run local processes, or convert PDFs and digital signatures. AL Bridge closes that gap. It is the shared foundation - a local agent plus AppLibra cloud services, orchestrated from BC over an encrypted job queue - that every AppLibra connector app plugs into as a module. Install it once and the whole connector family can reach the on-premise and external world.
Key features
- Local agent via job queue - modules queue an encrypted job; a local service verifies the module licence, decrypts it and runs it on site, driverless, with nothing installed on BC.
- File-system operations - save, create or check folders, move and copy, read file or folder, delete, extract XML, including reading inbound folders.
- AppLibra cloud services - PNG-to-GRF for Zebra labels, PDF from JSON templates, PDF page count, e-invoice P7M signature decoding and attachment extraction.
- Generic REST client - calls external APIs with Basic Auth or Bearer token, headers, body and ETag, used for carriers, OAuth and cloud services.
- Built in - PDF viewer add-in, job logs, error messages and AES encryption of job content.
Business benefits
- SaaS without limits - printing, file access and local integrations from a cloud ERP.
- Driverless - no Windows drivers or installs on Business Central.
- One shared base - a single infrastructure instead of a custom bridge per integration.
Typical scenarios
- Print from SaaS - send labels and documents to local printers.
- File exchange - read and write local folders such as e-invoice SDI and PEC folders.
- Carriers and APIs - reach carrier and cloud services through the REST client.
What makes it different
AL Bridge is not another point integration: it is the enabling glue of the AppLibra platform. It rides the free AL Message Passing bus, so one encrypted job queue and one cloud-service layer serve the entire connector family - printing, files, PowerShell, carriers and e-invoicing all compose over the same foundation, with each capability licensed as its own module.
