Start with what is going wrong.
You do not need to know whether the answer is an API, automation or data project. Choose the symptom that sounds familiar. Each guide shows what to check, what usually causes it and where specialist help fits.
Your automation keeps failing, and nobody notices
Trace one failed record from trigger to business outcome, repair the responsible layer, then add safe retries and an alert for the person who can act.
Diagnose this problemYour stock numbers do not match between systems
Choose one stock authority, trace every event and writer for a real SKU, then fix the ownership, mapping or delivery rule that first causes the figures to diverge.
Diagnose this problemInvoice entry and approvals are taking too long
Measure the whole invoice route first, automate stable capture and routing steps, and keep people in control of exceptions, approvals and payment release.
Diagnose this problemThe numbers do not match between your systems
Take one disputed record, align the definitions and dates, then trace it through each source, transformation and report before rebuilding anything.
Diagnose this problemXero and your CRM sync, but the records are wrong
Map the objects, stable identifiers, field ownership and historical replay rules before changing or re-running the sync.
Diagnose this problemThese pages cover problems evidenced in UK search language, practitioner discussions and APIwise's current service material. They do not promise a result before the systems and baseline have been checked.
