Connect the workflow your standard tools miss
How we help
A one-off script may work until an event arrives twice, a credential expires or an older system rejects a new field. Without an agreed contract, the receiving team cannot tell whether an operation failed, is still pending or already completed.
BrownBag reviews the available interfaces and designs the smallest useful connection for the business task. We specify requests, responses and events, implement access controls and duplicate handling, and document how the team detects and recovers from failed exchanges.

How the work is handled
Agree the interface contract
Define record identifiers, required fields, update ownership and expected outcomes. Review authentication, supported access and any rate or payload limits before selecting an API, webhook or file-based approach.
Implement reliable event handling
Build the agreed endpoints or event consumers. Validate incoming data, preserve transaction references and use duplicate protection so a retry does not accidentally create a second order or operation.
Test recovery and hand over
Exercise timeouts, rejected records, out-of-order events and credential changes. Deliver examples and operational instructions showing how to inspect failures, replay eligible events and escalate an unresolved problem.
Clear handover

Your questions, answered
What is the difference between an API and a webhook?
An API lets one system request information or an action. A webhook sends an event when something changes. The useful design may combine both, such as receiving an order event and fetching its full details.
Can we add more events later?
Yes. A documented contract makes additions easier to review. We assess compatibility, receiving-system behaviour and recovery rules before introducing a new event or changing an existing field.
